<br />
=== Crank sensor ===<br />
[[File:07k crank sensor.jpg|thumb|right|07k crank sensor with plug]]<br />
<br />
The 07K engine uses a Hall Effect crank position sensor. This is synced with the cam sensor for Dual Wheel Missing Tooth engine operation and VVT. <br />
<br />
==== Crank sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.'''<br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should be shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
For MegaSquirt, a pull-up resistor is needed for the ECU to recognize the signal. This is done by wiring a resistor between 5v and sensor output.<br />
<br />
===== Incorrect wiring diagrams =====<br />
[[File:07k vs 1.8 crank sens.png|thumb|right|07k vs 1.8t crank sensor comparison]]<br />
<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance (VR). Both are three-wire sensors. The 07k uses two small hex bolts and the 1.8t uses a single bolt.<br />
<br />
In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS), the same sensor diagram is shown but different sensors are used. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground — this is incorrect for the 07k.<br />
<br />
The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />

<br />
=== Cam Sensor ===<br />
[[File:07k Cam sensor.jpg|thumb|right|07k Cam sensor]]<br />
<br />
The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />
==== Cam sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />

<br />
=== Throttle body ===<br />
The 07k uses a drive-by-wire throttle body. To control it, you need a 3rd-party throttle controller called a DBW controller. Preferably wire the controller via CAN bus to the ECU to avoid extra wiring.<br />
<br />
A DBW controller can be made using Arduino or purchased (e.g., ldperformance DBW or DBWX2).<br />

<br />
'''Pin 6: Ground'''<br />
<br />

=== Accelerator Pedal ===<br />
I have only messed with MK5 and MK7 pedals and they had identical pin layouts. They are as follows:<br />

==== Accelerator Pedal Pinout ====<br />
'''Pin 1: 5V'''<ref>https://files.fueltech.net/manuals/Throttle%20Guide.pdf</ref><br />
<br />
'''Pin 2: 5V'''<br />

'''Pin 3: Ground'''<br />
<br />
'''Pin 4: Output 1'''<br />
<br />
'''Pin 5: Ground'''<br />
<br />
'''Pin 6: Output 2'''<br />
<br />
If you want to bypass the safety of having multiple 5v inputs, wire both 5v together. This can also be done with the grounds.<br />

<br />
==== VW/Audi COP issue ====<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 IC being limited by the low trigger resistance (<1k ohm). Standard COPs are ~440 ohm, which causes excessive current draw, misfires, and potential EMI issues leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix is to use three TC4427 ICs (scalable per cylinder count) and one 15 ohm resistor on each output.<br />

For high frequency valves such as idle valves or VVT solenoids it is necessary to connect a diode from signal to 12V in the loom. Alternatively a small jumper wire can be installed inside the case to make all outputs high-frequency capable - this is detailed in the assembly section. (c) 2014-8 James Murray 2018-08-01<br />

Alternatively a small jumper wire can be installed inside the case to make all outputs high-frequency capable - this is detailed in the assembly section. (c) 2014-8 James Murray 2018-08-01<br />

<br />
=== Crank sensor ===<br />
[[File:07k crank sensor.jpg|thumb|right|07k crank sensor with plug]]<br />
<br />
The 07K engine uses a Hall Effect crank position sensor. This is synced with the cam sensor for Dual Wheel Missing Tooth engine operation and VVT. <br />
<br />
==== Crank sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.'''<br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should be shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
For MegaSquirt, a pull-up resistor is needed for the ECU to recognize the signal. This is done by wiring a resistor between 5v and sensor output.<br />
<br />
===== Incorrect wiring diagrams =====<br />
[[File:07k vs 1.8 crank sens.png|thumb|right|07k vs 1.8t crank sensor comparison]]<br />
<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance (VR). Both are three-wire sensors. The 07k uses two small hex bolts and the 1.8t uses a single bolt.<br />
<br />
In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS), the same sensor diagram is shown but different sensors are used. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground — this is incorrect for the 07k.<br />
<br />
The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />
<br />
<br clear="all"><br />
<br />
=== Cam Sensor ===<br />
[[File:07k Cam sensor.jpg|thumb|right|07k Cam sensor]]<br />
<br />
The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />
==== Cam sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />

<br />
=== Throttle body ===<br />
The 07k uses a drive-by-wire throttle body. To control it, you need a 3rd-party throttle controller called a DBW controller. Preferably wire the controller via CAN bus to the ECU to avoid extra wiring.<br />
<br />
A DBW controller can be made using Arduino or purchased (e.g., ldperformance DBW or DBWX2).<br />

I have only messed with MK5 and MK7 pedals and they had identical pin layouts. They are as follows:<br />

'''Pin 1: 5V'''<ref>https://files.fueltech.net/manuals/Throttle%20Guide.pdf</ref><br />

<br />
'''Pin 4: Output 1'''<br />
<br />
'''Pin 5: Ground'''<br />
<br />
'''Pin 6: Output 2'''<br />
<br />
If you want to bypass the safety of having multiple 5v inputs, wire both 5v together. This can also be done with the grounds.<br />

<br />
==== VW/Audi COP issue ====<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 IC being limited by the low trigger resistance (<1k ohm). Standard COPs are ~440 ohm, which causes excessive current draw, misfires, and potential EMI issues leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix is to use three TC4427 ICs (scalable per cylinder count) and one 15 ohm resistor on each output.<br />

Note the diode. The MS3X mid-current outputs are configured for low-frequency valves (e.g. boost or nitrous solenoids.) For high frequency valves such as idle valves or VVT solenoids it is necessary to connect a diode from signal to 12V in the loom. Alternatively a small jumper wire can be installed inside the case to make all outputs high-frequency capable - this is detailed in the assembly section. (c) 2014-8 James Murray 2018-08-01<br />

<div>== General Setup ==<br />
<br />
=== Crank sensor ===<br />
[[File:07k crank sensor.jpg|thumb|right|07k crank sensor with plug]]<br />
<br />
The 07K engine uses a Hall Effect crank position sensor. This is synced with the cam sensor for Dual Wheel Missing Tooth engine operation and VVT. <br />
<br />
==== Crank sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.'''<br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should be shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
For MegaSquirt, a pull-up resistor is needed for the ECU to recognize the signal. This is done by wiring a resistor between 5v and sensor output.<br />
<br />
===== Incorrect wiring diagrams =====<br />
[[File:07k vs 1.8 crank sens.png|thumb|right|07k vs 1.8t crank sensor comparison]]<br />
<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance (VR). Both are three-wire sensors. The 07k uses two small hex bolts and the 1.8t uses a single bolt.<br />
<br />
In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS), the same sensor diagram is shown but different sensors are used. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground — this is incorrect for the 07k.<br />
<br />
The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />
<br />
<br clear="all"><br />
<br />
=== Cam Sensor ===<br />
[[File:07k Cam sensor.jpg|thumb|right|07k Cam sensor]]<br />
<br />
The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />
==== Cam sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />

=== Knock Sensor(s) ===<br />
<br />
=== Throttle body ===<br />
The 07k uses a drive-by-wire throttle body. To control it, you need a 3rd-party throttle controller called a DBW controller. Preferably wire the controller via CAN bus to the ECU to avoid extra wiring.<br />
<br />
A DBW controller can be made using Arduino or purchased (e.g., ldperformance DBW or DBWX2).<br />

<br />

<br />

I have only messed with MK5 and MK7 pedals and they had identical pin layouts. They are as follows:<br />

'''Pin 1: 5V'''<ref>https://files.fueltech.net/manuals/Throttle%20Guide.pdf</ref><br />

<br />
'''Pin 3: Ground'''<br />
<br />
'''Pin 4: Output 1'''<br />
<br />
'''Pin 5: Ground'''<br />
<br />
'''Pin 6: Output 2'''<br />
<br />
If you want to bypass the safety of having multiple 5v inputs, wire both 5v together. This can also be done with the grounds.<br />

[[File:COP wiring diagram.png|thumb|right|Wiring diagram for COP<ref>http://www.extraefi.co.uk/</ref>]]<br />
<br />
==== VW/Audi COP issue ====<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 IC being limited by the low trigger resistance (<1k ohm). Standard COPs are ~440 ohm, which causes excessive current draw, misfires, and potential EMI issues leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix is to use three TC4427 ICs (scalable per cylinder count) and one 15 ohm resistor on each output.<br />

<br />
==== VW/Audi COP issue ====<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 IC being limited by the low trigger resistance (<1k ohm). Standard COPs are ~440 ohm, which causes excessive current draw, misfires, and potential EMI issues leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix is to use three TC4427 ICs (scalable per cylinder count) and one 15 ohm resistor on each output.<br />

<nowiki>*</nowiki>Note the diode. The MS3X mid-current outputs are configured for low-frequency valves (e.g. boost or nitrous solenoids.) For high frequency valves such as idle valves or VVT solenoids it is necessary to connect a diode from signal to 12V in the loom. Alternatively a small jumper wire can be installed inside the case to make all outputs high-frequency capable - this is detailed in the assembly section. (c) 2014-8 James Murray 2018-08-01<br />

<br />
=== Crank sensor ===<br />
[[File:07k crank sensor.jpg|thumb|right|07k crank sensor with plug]]<br />
<br />
The 07K engine uses a Hall Effect crank position sensor. This is synced with the cam sensor for Dual Wheel Missing Tooth engine operation and VVT. <br />
<br />
==== Crank sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.'''<br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should be shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
For MegaSquirt, a pull-up resistor is needed for the ECU to recognize the signal. This is done by wiring a resistor between 5v and sensor output.<br />
<br />
===== Incorrect wiring diagrams =====<br />
[[File:07k vs 1.8 crank sens.png|thumb|right|07k vs 1.8t crank sensor comparison]]<br />
<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance (VR). Both are three-wire sensors. The 07k uses two small hex bolts and the 1.8t uses a single bolt.<br />
<br />
In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS), the same sensor diagram is shown but different sensors are used. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground — this is incorrect for the 07k.<br />
<br />
The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />
<br />
<br clear="all"><br />
<br />
=== Cam Sensor ===<br />
[[File:07k Cam sensor.jpg|thumb|right|07k Cam sensor]]<br />

The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />

=== Throttle body ===<br />
The 07k uses a drive-by-wire throttle body. To control it, you need a 3rd-party throttle controller called a DBW controller. Preferably wire the controller via CAN bus to the ECU to avoid extra wiring.<br />
<br />
A DBW controller can be made using Arduino or purchased (e.g., ldperformance DBW or DBWX2).<br />

<br />
'''Pin 4: Output 1'''<br />
<br />
'''Pin 5: Ground'''<br />
<br />
'''Pin 6: Output 2'''<br />
<br />
If you want to bypass the safety of having multiple 5v inputs, wire both 5v together. This can also be done with the grounds.<br />

=== VVT ===<br />
<br />
The VVT idle valve wiring can be found in the manual in section 3.5.4.4 (Page 47/225 MS3X/V3.57 Hardware Guide). This section has been copied below.<br />
<br />
3.5.4.4 2-wire PWM idle valve (MS3X) <br />
<br />
The MS3X connector allows direct connection of 2-wire idle valves. <br />

<br />
<br />
<br />
<br />
<br />
<br />
<nowiki>*</nowiki>Note the diode. The MS3X mid-current outputs are configured for low-frequency valves (e.g. boost or nitrous solenoids.) For high frequency valves such as idle valves or VVT solenoids it is necessary to connect a diode from signal to 12V in the loom. Alternatively a small jumper wire can be installed inside the case to make all outputs high-frequency capable - this is detailed in the assembly section. (c) 2014-8 James Murray 2018-08-01<br />

<div>== General Setup ==<br />
<br />
=== Crank sensor ===<br />
[[File:07k crank sensor.jpg|thumb|right|07k crank sensor with plug]]<br />
<br />
The 07K engine uses a Hall Effect crank position sensor. This is synced with the cam sensor for Dual Wheel Missing Tooth engine operation and VVT. <br />
<br />
==== Crank sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.'''<br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should be shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
For MegaSquirt, a pull-up resistor is needed for the ECU to recognize the signal. This is done by wiring a resistor between 5v and sensor output.<br />
<br />
===== Incorrect wiring diagrams =====<br />
[[File:07k vs 1.8 crank sens.png|thumb|right|07k vs 1.8t crank sensor comparison]]<br />
<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance (VR). Both are three-wire sensors. The 07k uses two small hex bolts and the 1.8t uses a single bolt.<br />
<br />
In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS), the same sensor diagram is shown but different sensors are used. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground — this is incorrect for the 07k.<br />
<br />
The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />

<br />
=== Cam Sensor ===<br />
[[File:07k Cam sensor.jpg|thumb|right|07k Cam sensor]]<br />

The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />

=== Throttle body ===<br />
The 07k uses a drive-by-wire throttle body. To control it, you need a 3rd-party throttle controller called a DBW controller. Preferably wire the controller via CAN bus to the ECU to avoid extra wiring.<br />
<br />
A DBW controller can be made using Arduino or purchased (e.g., ldperformance DBW or DBWX2).<br />

<br />
'''Pin 6: Ground'''<br />
<br />
=== Map sensor ===<br />
<br />
=== VVT ===<br />

=== Accelerator Pedal ===<br />
I have only messed with MK5 and MK7 pedals and they had identical pin layouts. They are as follows:<br />
<br />
==== Accelerator Pedal Pinout ====<br />
'''Pin 1: 5V'''<ref>https://files.fueltech.net/manuals/Throttle%20Guide.pdf</ref><br />

<br />
'''Pin 4: Output 1'''<br />
<br />
'''Pin 5: Ground'''<br />
<br />
'''Pin 6: Output 2'''<br />
<br />
If you want to bypass the safety of having multiple 5v inputs, wire both 5v together. This can also be done with the grounds.<br />

The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 IC being limited by the low trigger resistance (<1k ohm). Standard COPs are ~440 ohm, which causes excessive current draw, misfires, and potential EMI issues leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix is to use three TC4427 ICs (scalable per cylinder count) and one 15 ohm resistor on each output.<br />

==== VW/Audi COP issue ====<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 Integrated circuit is limited by the resistance of the trigger of the coil being lower than 1k ohm. The resistance of the standard COPs is ~440 ohm. This causes the coils to pull more current than SNx4AHCT541 can handle and leads to misfires and potential EMI issues in the MS3X leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix to this issue is using three TC4427 Integrated circuits that can handle the required higher current (the number of ICs can be scaled for more cylinders) and one 15 ohm resistor on the output of each TC4427.

This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance(VR). Both are three-wire sensors, The 07k uses two small hex bolts and the 1.8t uses a single bolt. In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS) have the same sensor diagram but use different sensors. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground, this is incorrect for the 07k. The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />

[[File:07k Cam sensor.jpg|thumb|07k Cam sensor]]<br />
The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />
==== Cam sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.''' <br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />

<br />
If you want to bypass the safety of having multiple 5v inputs, wire both the 5v together, this can also be done with the grounds.<br />

==== VW/Audi COP issue ====<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 Integrated circuit is limited by the resistance of the trigger of the coil being lower than 1k ohm. The resistance of the standard COPs is ~440 ohm. This causes the coils to pull more current than SNx4AHCT541 can handle and leads to misfires and potential EMI issues in the MS3X leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix to this issue is using three TC4427 Integrated circuits that can handle the required higher current (the number of ICs can be scaled for more cylinders) and one 15 ohm resistor on the output of each TC4427.

This causes the coils to pull more current than SNx4AHCT541 can handle and leads to misfires and potential EMI issues in the MS3X leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix to this issue is using three TC4427 Integrated circuits that can handle the required higher current (the number of ICs can be scaled for more cylinders) and one 15 ohm resistor on the output of each TC4427.

<div>== General Setup ==<br />
<br />
=== Crank sensor ===<br />
[[File:07k crank sensor.jpg|thumb|07k crank sensor with plug]]<br />
The 07K engine uses a Hall Effect crank position sensor. This is synced with the cam sensor for Dual Wheel Missing Tooth engine operation and VVT. <br />
<br />
==== Crank sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />
<br />
'''Pin 1: 5v.'''<br />
<br />
'''Pin 2: Sensor output.'''<br />
<br />
'''Pin 3: Sensor ground.'''<br />
<br />
For best results this sensor should shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
For Mega Squirt, a pull up resistor is needed for the ecu to recognize the signal. This is done by wiring a resistor between 5v and sensor output.<br />
<br />
<br />
===== Incorrect wiring diagrams =====<br />
[[File:07k vs 1.8 crank sens.png|thumb|07k vs 1.8t crank sensor comparison ]]<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance(VR). Both are three-wire sensors, The 07k uses two small hex bolts and the 1.8t uses a single bolt. In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS) have the same sensor diagram but use different sensors. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground, this is incorrect for the 07k. The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />
<br />

<br />
=== Cam Sensor ===<br />
[[File:07k Cam sensor.jpg|thumb|07k Cam sensor]]<br />
The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />
<br />
==== Cam sensor pinout ====<br />
On the rear of the sensor plug the wires are numbered 1 through 3.<br />

<br />
==== 3 Wire ====<br />
<br />
=== Knock Sensor(s) ===<br />
<br />
=== Throttle body ===<br />
The 07k uses a drive by wire throttle body, in order to control the thorttle body, you need a 3rd party throttle controller called DBW controller. Preferably wire the controler via can bus to the ecu to avoid extra wiring. A DBW control can be made by Arduino or purchased like the ldperformance DBW or DBWX2.<br />
<br />
=== Map sensor ===<br />
<br />
=== VVT ===<br />
<br />
=== Accelerator Pedal ===<br />
I have only messed with mk5 and mk7 pedals and they had identical pin layouts as follows. <br />
<br />
==== Accelerator Pedal Pinout ====<br />
'''Pin 1: +5'''<br />
<br />
'''Pin 2: +5'''<br />
<br />
'''Pin 3: ground'''<br />
<br />
'''Pin 4: Output 1'''<br />
<br />
'''Pin 5: ground'''<br />
<br />
'''Pin 6: Output 2'''<br />
<br />
If you want to bypass the safety of having multiple 5v inputs, wire both the 5v together, this can also be done with the grounds.<br />

[[File:07k vs 1.8 crank sens.png|thumb|07k vs 1.8t crank sensor comparison ]]<br />
For best results this sensor should shielded and kept away from sources of EMI like the starter, high-current wires, and any noise source.<br />
<br />
===== Incorrect wiring diagrams =====<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance(VR). Both are three-wire sensors, The 07k uses two small hex bolts and the 1.8t uses a single bolt. In the [[Wiring Diagrams|wiring diagrams]] of both the 1.8t and the B series of engines (BGP, BGQ, BPS) have the same sensor diagram but use different sensors. Per the diagram, both show the 3-wire VR sensor with VR+, VR-, and shield ground, this is incorrect for the 07k. The C series of engines (CBTA, etc.) does not display a diagram for the sensor.<br />
<br />
=== Cam Sensor ===<br />
The 07k uses a single Hall effect sensor on the intake cam. This is synced with the crank sensor for Dual Wheel Missing Tooth engine operation and VVT.<br />

==== VW/Audi COP issue ====<br />
[[File:COP wiring diagram.png|thumb|Wiring diagram for COP<ref>http://www.extraefi.co.uk/</ref>]]<br />
<br />
The MegaSquirt3X cannot drive the VW/Audi coils directly. This is due to the SNx4AHCT541 Integrated circuit is limited by the resistance of the trigger of the coil being lower than 1k ohm. The resistance of the standard COPs is ~440 ohm. This causes the coils to pull more current than SNx4AHCT541 can handle and leads to misfires and potential EMI issues in the MS3X leading to RPM sync loss.<br />
<br />
==== VW/Audi COP fix ====<br />
The fix to this issue is using three TC4427 Integrated circuits that can handle the required higher current (the number of ICs can be scaled for more cylinders) and one 15 ohm resistor on the output of each TC4427. <br />

<div>== General Setup ==<br />
<br />
=== Crank sensor ===<br />
The 07K engine uses a Hall Effect crank position sensor. <br />
<br />
<br />
<br />
<br />
This sensor is easily confused with the similar-looking 1.8t Variable-Reluctance(VR). Both are three-wire sensors, The 07k uses two small hex bolts and the 1.8t uses a single bolt.<br />
