This always works for me.

I have been trying to change ignition tables for my ecu to suite better for added turbo charger.

I think I also have a Motronic 3.1 somewhere. It's the ecu from the E36 BMW I believe. I actually took the M1.3 because I thought it would be easier to Wed, 28 Oct 2009 23:28:34 GMT Alexis Pavlov http://autos.groups.yahoo.com/group/BoschDME/message/554 http://autos.groups.yahoo.com/group/BoschDME/message/554 The BMW m1.3 already has this huge I/O component with 3 x 8bit ports and some other stuff. Unfortunately when I disassembled the ML3.1 I wrote all my notes on Wed, 28 Oct 2009 18:08:27 GMT Christian http://autos.groups.yahoo.com/group/BoschDME/message/553 http://autos.groups.yahoo.com/group/BoschDME/message/553 BMW 320i E30 for the motronic m1.3 Opel kadett GSI 16V for the motronic 2.5 Regards, Chris Wed, 28 Oct 2009 17:29:23 GMT Alexis Pavlov http://autos.groups.yahoo.com/group/BoschDME/message/552 http://autos.groups.yahoo.com/group/BoschDME/message/552 What car does your M1.3 come from ?

After a while I found a schematic and disassembled files here in this NG of the M1.3. So I Wed, 28 Oct 2009 15:14:23 GMT Alexis Pavlov http://autos.groups.yahoo.com/group/BoschDME/message/550 http://autos.groups.yahoo.com/group/BoschDME/message/550 Hi Chris, I spent some time on that. I did not go up to the end, I just wanted to know how everything works to be able to rewrite the firmware. Other guys went Wed, 28 Oct 2009 13:27:40 GMT Christian http://autos.groups.yahoo.com/group/BoschDME/message/549 http://autos.groups.yahoo.com/group/BoschDME/message/549 Hello Alexis, Thanks for the answer. I've already been looking a little to the assembly code and ofcourse some more questions raise. How do they determine Tue, 27 Oct 2009 16:13:25 GMT Alexis Pavlov http://autos.groups.yahoo.com/group/BoschDME/message/548 http://autos.groups.yahoo.com/group/BoschDME/message/548 Hi, I believe it triggers on the falling edge. It counts every tooth and compares the length of the previous and the new tooth. If there is a difference of 2 Tue, 27 Oct 2009 10:36:48 GMT Christian http://autos.groups.yahoo.com/group/BoschDME/message/547 http://autos.groups.yahoo.com/group/BoschDME/message/547 Hi guys, I was wondering if somebody knows how the trigger wheel decoding algorithm works inside the older motronic ecus. I believe they trigger on both edges Sat, 24 Oct 2009 02:05:37 GMT efidabbler http://autos.groups.yahoo.com/group/BoschDME/message/546 http://autos.groups.yahoo.com/group/BoschDME/message/546 Very interesting, take note! I have not seen anyone who has worked that deep into the KLR. I sort of assumed that the guys at Dinan knew something about Bosch Fri, 23 Oct 2009 10:32:21 GMT http://autos.groups.yahoo.com/group/BoschDME/message/545 http://autos.groups.yahoo.com/group/BoschDME/message/545 Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the BoschDME group.

It is a joke. They just set all target boost values to FF (220 kPa). With the built in 200kPa sensor this
