Hello,

I need help identifying some maps from MSA 15.5-5.5 (Jeep Cherokee year 1998 2.5 TDI)

I've seen msa15-tuning-guide, but not much help in this specific case.

For now I have identified this maps:

052AE - Drivers Wish ????
02370 - Drivers Wish ????
04620 - Smoke limiter
05826 - Pump Voltage

I can not find:

EGR map
Boost map (Turbo map)
Boost limit
Torque limit
N108 Beginning of Injection map
N75
SVBL

Any tip??

Best regards,
Rui

There is dump files:

cherokee_2.5tdi_dump.zip

.

This Jeep has the 2.5 TDI engine, not 2.5TD (CRD) as it appears on many websites on the internet.

In fact this jeep also came out with the 2.5TD (CRD) engine with the ECU EDC15 C2.

"location" is the address of a map in the file.
ECU uses different maps for calculations, and i need to identify the correct maps to modify.
You have maps to control Injection quantity, turbo pressure, start of injection...
