Hacking the Motronic ECU (Audi RS2)

[S2central.net]

Interesting... does it cover both chips ?

If I had more money I would buy it to cross-check against my own info and see what else can be gleamed from it. Seems a very new product. Could be great or could be useless. Tread carefully would be my advise.

I bought this. It is a map editor & came setup for rs2

Thanks. Where you take this information?

[newborg]

Let's give some more hints to cid to keep him going. 0x3A, 0x3F, 0x38 and 0x37 are figured out correctly - thanks. Can you say what is 0x36?

36 - Voltage
37 - Air Temp
38 - Head Temp
3A - RPM
3F - Load

I assume you was the one who requested s2dude to remove the info he wrote. That's someting I'd consider opposite to helping.

I've been thinking about programming a hondata type sw for my own joy. Finding a reasonably priced emu is the problem. Xtronics has its problems too...

Yes indeed cut-off - one cell, I picked it empirically.
Many thanks for your reply.

By correcting for reaching a certain load, as I understand it, it maps 3A-3F, with the axis 3F must begin with a particular importance - the border early correction? How many such cards for the correction of the ignition? I understand that nobody wants to share information, but the issue for me is very urgent.

Faheemo I can raise the limiter no problem.

There are no separate wot maps in our cars. There are some correction maps that are not read before certain load thresholds has been passed.

Good afternoon. I need help. Can you please tell whether there is in our ECU maps WOT ignition and fuel? I found a card ignition / fuel, but changing the map of the ignition angle change only at medium loads. I also have an emulator with an address trace, it shows that when there is no recourse to WOT maps ignition / fuel 16x16. I know about 6 cards 16x16 ignition, the brain turns to only one - the first, and then only in the mode of partial loads. How the brain takes the values of the angles at WOT?

Sorry for my English.

TunerPro = nice but I have been waiting for V5 for well over a year now... sad but true.

[Faheemo]

Anybody have Info they willing to share on lifting the limiter on our cars ? Please !

well.. as long as its feeding the right signals to the ecu I guess you could use one. And if it didn't, it would be extremly useless. As far as i can see it works just like a pigyback ecu. But this would be a pigyback MAF (if in that mode).
Also, according to the manual, it uses TunerPro RT. And thats not that hard a program to use.

I dont want to disorientate the Discussion here but can the Motronic "hackers" take a look at this Option. Can it be that it will be a good alternative for us?

According to a certain yahoo group, there is just a resistor that seperates the RS2 (551C?)ECU from the AAN(551A). Except for the bin's ofcourse.
Wouldn't that indicate that the software should be quite similar aswell?
