= ACCELERATOR PEDAL: =

== Desired Torque Profile (0/1/2/3/4/Reverse) ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Accelerator pedal position (%)

'''Map:''' Target engine torque

This map defines the relationship between accelerator pedal position and requested engine torque (throttle response).

* Lower values → smoother and more progressive response
* Higher values → more aggressive and dynamic response

Adjust carefully to maintain drivability and traction.

= BOOST CONTROL =

== Boost Solenoid Duty Cycle ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Actual gear

'''Map:''' Boost control solenoid duty cycle (%)

This map controls the duty cycle of the boost control solenoid.

Continuous high-duty operation may reduce solenoid valve lifespan.

To prevent unnecessary solenoid activity:

* Set appropriate minimum engine speed
* Set appropriate minimum MAP pressure

----

= FUEL: =
All fuel-related adjustments must be performed responsibly. Incorrect settings may cause severe engine damage.
----

== Cold Start Factor ==
'''X axis:''' Engine coolant temperature (°C)

'''Map:''' Cold start fuel correction factor

A cold engine requires additional fuel for stable operation.

Adjust this map if:

* Idle is unstable during warm-up
* AFR/lambda is incorrect during cold start
* Engine stalls or runs excessively rich during warm-up

----

== Fuel Mass to Injection Time Conversion ==
'''Map type:''' Single value

Defines the conversion factor between calculated fuel mass and injector opening time.

Adjustment is required when replacing injectors.

* Larger injectors → lower map value
* Smaller injectors → higher map value

Always verify changes using logs.
----

== Injector Linearization Correction ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Injection time (ms)

'''Map:''' Fuel correction factor

This map corrects injector non-linearity.

* Higher values → more injected fuel
* Lower values → less injected fuel

Adjust using lambda correction logs.

Ensure actual lambda matches target lambda under all load conditions.
----

== Fuel Trim Configuration ==
I don't know what this map doing :D
----

== Injector Dead Time ==
'''X axis:''' Battery voltage (V)

'''Map:''' Injector dead time (ms)

Dead time values are injector-specific.

Adjustment is not required unless injectors are replaced.
----

== Lambda Target ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Engine load (%)

'''Map:''' Target lambda value

Defines the target air-fuel ratio.

Adjust this map to:

* Optimize performance
* Improve fuel economy
* Ensure safe operation under boost

----

== Minimum Measurable Lambda ==
'''Map type:''' Single value

Defines the diagnostic lower limit for the lambda sensor.

If your target lambda is lower than this limit, adjust this value to avoid diagnostic fault codes.
----

= IDLE =

== Idle Target Speed ==
'''X axis:''' Engine coolant temperature (°C)

'''Y axis:''' Actual gear

'''Map:''' Target idle speed (RPM)

Defines engine idle speed under different temperature and gear conditions.
----

== RPM Curve After Start ==
'''X axis:''' Time since engine start (s)

'''Y axis:''' Engine coolant temperature (°C)

'''Map:''' Target idle speed (RPM)

Defines elevated idle speed strategy immediately after engine startup.

Used for:

* Improved cold-start stability

----

= IGNITION =
Incorrect ignition settings may cause engine knock and severe engine damage.

Always validate changes using knock logs and dyno testing.
----

== Ignition Advance ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Engine load (%)

'''Map:''' Ignition timing advance (°)

Defines base ignition timing.

Adjust to optimize:

* Power output
* Efficiency
* Knock resistance

Avoid large changes unless you fully understand ignition tuning principles.
----

== Minimum Ignition Angle ==
''(Recommended rename from "Latest possible ignition angle")''

'''X axis:''' Engine speed (RPM)

'''Y axis:''' Engine load (%)

'''Map:''' Minimum allowed ignition angle (°)

Defines the lower safety limit for ignition timing.

Adjust only if calculated ignition values fall below this threshold.
----

== Minimum Ignition Angle During Catalyst Heating ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Engine load (%)

'''Map:''' Minimum ignition angle during catalyst heating (°)

Defines ignition timing lower limit during catalyst warm-up phase.
----

== Dwell Maps ==
Modification is generally not recommended unless:

* Ignition coils are replaced
* System voltage behavior changes

Improper dwell settings may damage ignition coils.
----

= Overrun Fuel Cut-Off (Deceleration) =

== Fuel Cut-Off Delay During Gear Change ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Engine load (%)

'''Map:''' Delay time (s)

Defines how long fuel is delivered after accelerator release during gear change (clutch engaged).
----

== Overrun Fuel Cut-Off Delay ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Engine load (%)

'''Map:''' Delay time (s)

Defines how long fuel is delivered after accelerator release during engine braking.
----

== Fuel Cut-Off Delay at High RPM and High Catalyst Temperature ==
'''X axis:''' Engine speed (RPM)

'''Y axis:''' Catalyst temperature (°C)

'''Map:''' Delay time (s)

Defines delay before fuel cut-off under high thermal load conditions.
----

= Project Configuration =

== Catalyst Diagnosis ==
'''Map type:''' Single value

Set to:

* 1 → Catalyst diagnosis enabled
* 0 → Catalyst diagnosis disabled (cat-less setup)

----

== Catalyst Diagnosis (OBD2 Mode) ==
'''Map type:''' Single value

Set to:

* 1 → Enabled
* 0 → Disabled (cat-less setup)

----

== Lambda Sensor Configuration ==
'''Map type:''' Single value

Set to:

* 1 → Post-catalyst lambda sensor disabled
* 0 → Sensor enabled

----

== EVAP / Tank Ventilation System ==
'''Map type:''' Single value

Set to:

'''Y axis:''' Engine load (%)

'''Map:''' Intake camshaft advance angle (°)

Adjust this map to optimize torque and power delivery.

Dyno validation is strongly recommended for optimal results.
