So here is the situation:

I have a 04 with head gaskets leaking and I'm thinking of buying a built 06 Revup Motor.

Am I going to require wiring harness mods and ECU to get the Revup Motor to work in my car that has a Haltech Stand alone?

Thanks for any help / insight.

 

it will work with no modification. Your stock ecu will think its still a non revup. Only thing is you will have 2 sensors that are not connected.

 

buy my flashed revup ecu. i used this ecu with a haltech as well

 

Perfect solution
