This section is underdevelopment. Feel free to add content. Please note we documented the ME17.5.6, some maps might not be present in the ME17.5

Reading, writing and checksums

For reading and writing procedures refer to Reading and writing ECU (ME7.1.1)

Most flashing tools fix checksums automatically, if you wish to fix them manually, you can use LSuite

Engine management

The ME17.5 use a TC1766 micro-controller. The ME17.5.6 use a TC1767 micro-controller. The program memory and the maps are both stored into the MCU which defers from the ME7.1.1 that have two chipsets, one for the MCU and an extermal memory chipset to store the maps.

There is no public funktionsrahmen for the ME17.5. You can use the MED17.5 Funktionsrahmen which will have some difference regarding injection as the MED17 use direct injections strategies while the ME17 use ported injection. For the missing modules, you can refer to the ME7.5 Funktionsrahmen.

The ME17.5.6 have some differences versus the ME17.5, extra modules, extra strategies and different map name. You can refer to the MED17.1.62 funktionsrahmen

This ecu is load-dependent. The driver request a load and the ECU will target the requested load.
