BOSCH MOTRONIC ME7.1.1

BOSCH MOTRONIC ME7.1.1

BOSCH MOTRONIC ME7.1.1

(OP)
I have a BOSCH MOTRONIC ME7.1.1 ecu that i'm trying to tune.  There are a few questions I have.
I was told that around 018000 is where the I/O are located in memory... from looking at the hex and the ascii code, how do i know where the air pump, air vavle, fuel pump 1, fuel pump 2, ignition, etc is specifially located??  I have some of the protocals from the vehilcles protocal manual but it only states the pin on the ecu and the hex # for the particular I/O.


Any help would be appreciated

Thanks,
NicoliT

RE: BOSCH MOTRONIC ME7.1.1

read the memory, stimulate an input reread the memory. read memory and read outputs write to memory and reread outputs. if you can change only one thing at a time you should be able to  isolate what goes where. you can hope that the hex address of the port is in order. that would make the memory location a predetermined offset (such as 018000) plus the address (so port ff could be 0180ff) or plus the address times 16  (making the memory location 018ff0)
good luck :)

Thank you zimbali,

I have already tried those programs but I still haven't had any luck.  I have programs that can pick up the maps in the rom files but i need to know what each map does.  That is my dimlema.

I do have experience with  assembly language.  The intructions for this file and where the different maps are located must be somewhere in the beginning of the ROM file... if i only had the D**** files...


thanks,

RE: BOSCH MOTRONIC ME7.1.1

Have you tried WinOls? It has a trial version that works well for finding the maps, anyhow you need to distinguish the ignition and iinjection maps yourself. They are usually 12 X 12 tables that are located well at the bottom of Code. 12 X 12 is not a fixed thing and I'm not sure if there is any standard for Motronic ECUs out there. Download the program from www.evc.de .

Besides, after finding the maps what would you like to do? I imagine you want to change them somehow, and here is where you have a BIGGER problem: Checksum correction. You can find a debate on checksum correction on this forum which was back to 2 years ago (I have some posts on that as well). Then for that, you have two solutions:
1- Buying a software that can do the checksum correction for you, prices start from 1800-2000 Euro.

2- Giving your dump file to a tuning company and getting back the tuned file, which starts from 100 Euro.
