JZX100 auto ecu gear inputs
Hey Guys,
this is probably a longshot, but I am hoping to find someone who has done this / knows the ECU a bit better than me. I am having idling issues after driving with my 1jz vvti swap (JZX100) with the auto ecu and one of the diagrams i found has the pinout for the auto ECU. I have read that shorting the auto ECU to think it is in 2nd gear is the trick to fixing the idling issues after driving the car around a bit (always good idle from a fresh crank). Basically my question is, does anyone know if the 2nd gear input pin is a sinking or sourcing input? Does the pin (#G connector pin '2') need to be grounded or does it need to have 12V hooked into it to have the ECU think it is in 2nd gear? thanks Marko https://i50.photobucket.com/albums/f...jzx100-1-1.jpg |
My 1JZ GTE JZZ30 outputs battery voltage on the ECU pins for tranny solenoids. The other end of the solenoid is grounded at the tranny. Don't forget though, that it is a 12v OUTPUT, not input (obviously). So, I don't see how you can trick the ecu into thinking that it is in 2nd gear. The ECU commands it to be in second gear. I am assuming your VVTI is same
