Hello I´d like to disassemble MP3.1 bin. Can anybody upload 8k internal ROM for this ecu? Thanks Here you have 2 files from Motronic MP 3.1 Bosch nr 0261200695 fitted to Alfa 33 1.6 boxer. 32kb file are read with eprom reader, and 40 kb file are read with Tunerpro and Motronic plug-in, and contain ...

OK, I see. I have a bin from a Alfa 145 1.7 16v with 2.10.3 Motronic, and a pretty good xdf file. This xdf file I have made myself, and are tested on bench simulator. I post here the bin and xdf. This file are pretty similar to your Saab file, and I think you can make a equal xdf based on this one. ...

I hava explored similar ECU (2.10.3) for Alfa 145, and I have a pretty good XDF file for that.
What do you want to obtain for your project. Does the Saab have any immobilizer on these ECU's.
I will dig up and post later on.

I dont know how to adapt the ecu to work with different type of throttle potmeter.
However, get hold of a potmeter from BMW motorcycle fitted with Motronic MA2.2/2.4 ecu, this potmeter fit perfectly to the MA1.7 ecu.
This potmeter are plenty available on ebay.

Hi. Does anyone have experience in disassembly of this type of ecu. There is Intel SAB80C517 processor. I have all needed maps, however I need to alter the trigger angle for the inductive sensor. At the moment the ecu see TDC at the 15. tooth after missing tooths, and I want to alter this to the 20....

IF YOU HAVE ANY NEWS FOR BOSCH MA1.7

I need change tps ,you have xdf?


THANK YOU , IN ADVANCE.

Sorry, but I did not see the reply until now. If you still are interested I will make a quick xdf for your file.

In the last pages of this document there are some schematic for this ecu.
Document are in French.

HI. can someone help me make a full XDF or only solve a problem, this bosch ecu is the FIAT TIPO 1.6 ie, with MA1.7 monomotronic, has great performance, but the butterfly potentiometer is of the type with two tracks (double) this bosch injection not has MAF or MAP, would have to make better regulat...
