You need the supplementary manual for immobiliser models which can be downloaded here:

rhinoman.org/manuals/vitara/99501_60G10.pdf

I'm not aware of a version of that ECU that supports auto transmissions.

Hi, I read that you have extensive info on this ECU as this was also in your car and you even rebuilt one completely. Do you also have the pin-out of this ECU as I have this one in my green vitara (2000 1.6 8v, EFI) and converting this car from manual shift to automatic transmission 3-spd...so luckiliy the simple one. All wiring done, incl. 2 relais, but need to connect the white/yellow cable to the ECU for the TCC to function correctly.

A lot of the information that I had on this ECU was lost in a double hard drive failure a few years ago. I want to do some more mods to my Vit so I'm going back over the code, its not a lot different to the earlier 8V ECUs, the 56B30 and its variants, but the ECU uses updated and more powerful hardware based around the 76C175/MH6211 processor. The software has a few tweaks to handle the immobiliser and the stepper motor EGR and is restructured a little.

The source code is linked below, the TunerPro files are posted in the TunerPro section of the forum.

EE88 Source Code

The source code was originally disassembled mainly by hand in a word document but I'm slowly reformatting it in MiniIDE to allow it to be recompiled using the TASM assembler, details here:

I have most of the schematics for this ECU and the source code. Ignition and fuelling tables are known.
