Manual ECU on auto loom 1jz

**naten** · 24-03-2009, 04:41 PM

hey guys,

Ive searched all arvo and cant seem to find an answer to this. I have 1jzgte mated to a manual box with a auto ecu and loom (motor from jzz30). Can i use a jzx90 manual ecu? Pins are all the same etc but im not sure if its wired differently?

cheers

If the JZ is anything like the 1G and 7M just keep using the auto ecu, wont make a differance.

i have a suspected dodgy ecu so i gotta buy another one to try im not doing it for shits and giggles. Anyone know?

if the plugs are the same it shouldnt be an issue.

You're already using an auto ecu on a manual car. And you are asking if you can go back to manual ECU without repinning?
I am sure the answer is yes. Although you would have had to bridge the neutral start switch in the Auto ECU to get it to run on the manual anyway...

I know what you mean, but the loom is from auto car with auto ecu. Just didnt know if the manuals ran a different loom with different wiring

just going to try it and see what happens
