alright... Im not shure what ecu to run with the f20 swap... sum1 told me to run a p13 but then on here sum1 told me that the p13 would be a lil off... so I dunno what the ecu is for a f20 and where I could get one.. thanx in advance.

 

f20a or f20b?

 

it's an F20b the euro R motor.

 

i would say some kind of programmed ecu then.. you can use a p13, and yes it wont be perfect for the motor, but it should run it good enough.
and fyi, the f20b is not a euro r motor
