not sure of the service number. where it is located on the ECU? im totally capable of creating an XDF. i have made plenty of them for volkswagen and audi vehicles.

i have a 4.8 2001 silverado and im interested in getting into tuning the ECU is my truck. i see plenty of information on OBD1 tuning, logging and flashing but nothing as far as OBD2. i know HPtuners exists but i dont want to spend the kind of money if i dont have to. if i can get away with using tun...

If I understand the MC68HC25 datasheet correctly, given that (a) this circuit uses both /CS1 and /CS2 to enable the EPROM and (b) the mode-select byte at $7FBF is $17 (stock bin), then the EPROM is mapped to both address ranges $0800-7FFF (all the EPROM, excluding the lower addresses) and $E000-FFF...

i read the data sheet for the MC68HC25. i see $17 at 0x7FBF and that sort of makes sense. i see some code starting at 0x7FB0, there are 8 bits there and im going to guess they have something to do with the mode select register in the MC68HC25 maybe?

Is there a second chip in the computer? If I align the bin from 0x8000->0xFFFF then that puts the reset vector at 45FD which is out of range, and all the interupt vectors point to 6E18, which is also out of range. I would expect something to be at 45FD at least, although that could then remap the b...

I've been trying to learn how to decompile a digifant 1 ROM using ida pro but i just cant understand it. it seems there is a good bit of people here with a wealth of knowledge on the 6811 processor. would anyone be willing to help me with decompiling one of the stock BIN file? i have several other o...

Yes it does support KWP1281.

has anyone here ever worked with motronic 2.3.2? This ECU belongs to the 2.2 audi I5 20V turbo. it seems strange compared to all other motoronic ECU's of this era because it is 2 separate computers in 1, one for timing/fuel control and the other for boost control. im trying to learn more about this ...
