PCM Conversion Information

Yah, maybe we should just update the document attached in post #1.

Lots of good information here.

As a result of a quick read through the PDF referenced in the second post:

Missing from the abbreviation list: DOD, CKP (in header), CMP (in header), CAX

Missing from the engine RPO list: LK5, L52, LL8, LSJ, LD9, L61, LN2, LU3

References to I4/5/6, L4 and V6 for specific vehicles should be replaced with the RPO.

Which ECUs are MAP/TPS (are there any?) and which are MAF/MAP/TPS? Which ECUs can handle E85 (flex-fuel) with stock programming?

Should it be mentioned that all ECUs need engine temp and intake air temp sensors?

Should it be mentioned that DBC implementations need an IAC system (includes add IAC to the abbreviation list)?

DBW/DBC information is sparse, especially on the newer ECUs.

For those reading who must know what they mean:

DOD = Displacement on Demand, aka AFM

AFM = Active Fuel Management, aka DOD

IAC = Idle Air Control

CKP = symbol for Crank Position and/or its sensor

CMP = symbol for Cam Position and/or its sensor

CAX = calibration extension (if a user knows where an unpublished table resides at in the PCM's flash, they can make a definition to expose it)
