Ecu Mapping
Does anybody know where I can get map of the LEXUS V8 ECU. I am looking for the location of fuel-ratio map and Transmission map in the ECU. I want to access those locations using OBDII.

I read that car manufacturers promised to release their OBD-II information in september of last year, but I haven't seen it yet.

I know that it is proprietary information, but maybe someone can point me to the right place!

Good luck, I have yet to see that even in the repair manuals.

There is information about GM LT1 ECU, but I couldn't obtain anything about LEXUS ECU.

Assuming that LEXUS doen't make their own ECUs, who is their vendor?
