Hey Guys I need some Help Dr. Tweak could help with this I think. I saw a harness that allows you to use a gen3 ecu on a gen 2 engine and harness. I am wondering can something like that be done so i can use a gen 3 3sgte ecu on a gen3 3sge engine and harness. I appreciate your answers in advance.

Bump..... anyone

I am gonna give you the explaination. I am changing the intake as well fuell rail and injectors. It will basically be a 3sgte when i am dun.

This is what i have so far.


Gen 3 3sgte Intake manifold, fuel rail and injectors

Gen 3 3sgte exhaust manifold and turbo

Gen 3 3sgte map sensor

Ross 3sgte 8.5.1 comp forged pistons

Gen 3 3sgte Ecu

Gen 3 celica intercooler i also have a FMIC

I wanted to know i i can use the gen 3 ecu to run the engine. Thank You

why no just uase a piggy back on the ecu u have

IIRC the 3rd gen intake manifold doesn't bolt onto a 2nd gen head.

It doesn't i'm afraid, neither does the exhaust manifold.
