I own an 08 with an HR motor. I put Injen twin cold air intake, Borla headers, stillen test pipes, Borla true dual cat back exhaust, JWT light weight fliwheel, JWT stage 2 clutch and pressure plate on and now my rear O2's arent reading correctly even after i put extensions on them. I have been looking for an aftermarket ecu for quite some time and have not seen or heard of any that have been made. Does anyone know anything about when one might come out or if one has already come out can you point me in a good direction??

 

Moved to proper forum. SEARCH is your friend.

 

i didnt even know borla made headers for the HR motor...Never heard it before..

 

They don't.....

 

they dont make it for the motor but they fit. the only thing is your cats wont match up with the flange and so you have to change them out which is y i have the test pipes.

 

i have searched and for along time. like i said earlier if you could point me in the right direction that would be hlepful.

 

Uprev is your friend....... Gonna need a tune bc the rear O2 sensors are constantly thinking somethings wrong bc you have test pipes. Some times the extened sensor tube trick doesn't work.

An uprev tune should fix you right up except I'm not sure about UK cars.
