Rev2 ECU swap to Rev3 ECU - 6G Celicas Forums

Topic #75579 1 posts Started by jeffrosie


Has anybody done this, seem to remember reading about it.

What I basicly want to do is to rewire my ST185 with top mount air to air intercooler to run with a Rev3 SW20 3SGTE ECU as this is air to air as well.
This will help me get rid of the Air Flow Meter, but I will have to install Air Temp Sensor and Rev3 MAP Sensor along with Rev3 Injectors, maybe the ignitor too.
