After days and nights of study i was able to make the little mother fucker to read up to 255Kpa@4.97V (original was up to 207). But my sensor is 4 bar, so i`ll need to extend up to 400Kpa. First try was to divide each division of boost previously changed, but of course this will set an overflow on 1...

Delco HDRC.

Long time no see... meanwhile i didn`t used that car and didn`t had time to work on project, but if Bosch ME7.5 (C167 Processor) RAM values can be logged over OBD, would be possible to log RAM values from Motorola 68K over OBD? Any ideea HOW?

Thank you.

Did some digging, but still no luck... Is hard to understand Assembly when all languages that i know are high level (PHP, Java, Visual basic, C#)...

Too much pain in the a**. You need to simulate a lot of sensors, need to simulate RPM signal, pump rpm signal, injection pump controller, pedal position sensor, etc, etc. On this ECU check engine blinks if key is not recognized Done some tests, with changing BNE to BE in routines that i thinked are ...

Can be this part of IMMO? This is the bhi.w branch of a more complex function.


On my car VSS goes directly to ECU. K line goes from ECU to IMMO and then to other systems that use K line

Ok, on my car VSS goes from ABS unit to ECU (If VSS means same thing in my head and in yours or course )

Here did you put the osciloscpe? on K-Line?

Ok, you have some code from other Delco ECU that handles that information? because here i`m stucked, i don`t know what to search for.

My car doesn`t have a BCM.
Has this kind of Imobiliser in car: Car starts without right key, but shutdowns in few seconds and check engine light is blinking.
K line goes from ECU to IMMO and then to OBD port if this matters.
