Hey, thanks for those
I can't really say what the differences are between the MP3.1 and MP5.1 just yet - I only looked at an MP3.1 bin for the first time today.
Guessing that's from a 0.261.204.052 ECU, ex Peugeot 306 1.6?

Here's a very rough xdf to view the tables, lots of errors in it though.
A few of the tables are pretty easy to work out what they are, it definitely looks pretty similar to the MP3.1 table set except the one I was looking at had what I think are the target lambda tables set to 1.0 everywhere, but your MP5.1 bin actually has realistic values in there...

Hey, some weird one more

festy,thanks checked your xdf file.First 12X12 tables are possible VE! 6A07 6AB3
AFR duplicates - 6856,67AA.
And a lot of limp home values!
In case of sensors failure basicaly it can work only with CAS sensor!
Yes,it is from p 306 tu5jp 8 valves.
So,mp3.1 has dummy afr table(haven't checked - no suitable bins - do you have 0261200213 - 492 bin to check?).
It has similiar structure to earlier m and ml motronic.
And it is transitional stage for later bosch low cost mp.
Very interesting how the pressure to load function is implemented in mp3.1.
Dont say that is similiar to ml and m<1.5

MP3.1 uses same bosch chip companion 30015 as motronic ml4.1 and m1.3
As mp3.1 uses waste spark mode so it dont't use 30015 16 pin ZDG.
Schematics attached.No motronic mp3.1 ecu at this time.
405 1.9 sri mp3.1 bin added.

Do you have the whole schematic for the MP3.1? I'm in the middle of disassembling a bin and trying to work out some of the sensor connections.

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

Good information there. Thanks for posting!

Good morning

I have a Peugeot 306s16, with bosch motronic 3.2, anyone have the XDF file of this ECU?

Thanks

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 the 8 kb internal rom.
I think the MP3.1 fitted to Peugeot/Citroen 1.9 engine, Bosch nr: 0261200202/0261200214 have same internal rom, because I have tried to swap eprom between the Alfa ecu 0261200695 and the Peugeot ecu, and the ecu work as normal.
However, I can make a full 40 kb read from the Peugeot ecu if needed.
Enjoy.
