Thanks Mike, I don't really need any support as I have all the skills required to develop an ECU. The message was for those who need help from me :) Alexis...
I make a performance chip with a choice of rev limits of 6500(stock) or 7000rpm. For a short time, custom rev limits at the choice of the buyer. About 5 years...
There is still a mystery about the rev limiter on Alfa (ML4.1, it's something very close to 964 M1.3 but with a batch fire injection. The real time code part...
... I think you are right with that. To my current understanding, the ML3.1 needs ~65 usec between two theeths to do all the things necessary to keep the...
Hi all, Back to the temp -> value conversion If I tried to gather all the previous messages. I'm getting the following: First the NOT(byte) acquired from a...
... The first version of "my" formula is correct. T = 2/3 * <map out> - 40 Please notify that both formulas are (nearly) identical. grfstrm and I probably took...
This Yahoo groups software is a mess. It is difficult to exchange file based information and it is unknown to me how to add those informations to my messages. ...
Thanks. You are certainly right about the Bosch code made to work with any sensor. Actually I also need a Celsius value to display it on the LCD screen, I like...
... .6923º is correct not .694º. You are correct with this. I was up all night. Very tired. I couldn't even copy 3 numbers off a calculator without a...
... ML3.1 only has half-tooth precision. It uses quarter-tooth values during calculation of ignition timing but then converts it to a half-tooth value. ...
... I would agree on that. It actually just counts complete theeths and waits for an additional half-thooth, if a control bit is set. But it would be...
The Quarter-Tooth description was provided by my guy at BOSCH describing the ML1.1. He did say all Motronic. He had no interest in later models so all I got...
Hi, The question was already asked on www.checksumm.com/chiptuning/ Does someone know what's inside the TA13255A component which is found on M1.3 and latter...
... What markings are on the part? It is someone's custom in-house part number for special orders. It would help if I knew the manufacturer or his logo. What...
... I guess the M2.1 diagnostic is run by the main cpu with support of the Bosch 30015 chip. The second cpu is a Motorola 68705 - probably running the two...
Hello all, This is my 1st message in this interesting group. In the past I did 'some' disassembling of the code of a few old motronics, mainly the ML4.1 from...
In the ML4.1 the 60-2 wheel is used and the motronic calculates ignition in 0.75 degrees (8 steps in each tooth) accuracy. Considering the 22.5 degrees offset....
... Thanks for the great information. Looks like the ML4.1 already supports the multiple table set access like the later M2.1. Would be interesting to adapt...
... My Bad........ I have not looked at my Excel file for the 944S2 for 6 months and I copied the formula wrong. Put parentheses in the wrong spot. Wrong =0.75...
