G'day all,
Newby to the forum, not so new to Landcruisers, but I still need help.
I'm researching options to replace the factory ECU (Manual Transmission) and I have a shortlist of ECUs, but I've struck some unknowns with some stock ECU functions;
1. What does the Stock ECU do with the stop lamp switch input?
2. What circumstances (why) does the Stock ECU crank up the fuel pressure via the FPU pin and the fuel press VSV?
3. Does the Stock ECU heat the O2 sensor before start and after shut-down? How long for?
I'm assuming the previous question may have something to do with the STA input (Start sw)?
Does anyone here have any leads on answers to any of the above?
