Hey guys, I'm thinkin bout doin ECU tuning. The mods I got are AEMV2 CAI
Megan header and Megan Test pipe and Greddy TI-C dual.
Thinkin either J's N1 ECU or Apexi NEO.
Main question is, will the J's ECU work on my model?
2004 Ap1 F20c2?
S2k's here are different to the states so I'm strugglin to find info.
Would it be easier to just do Apexi?
Does the J's ECU replace my stock ECU?
please help!

 

Yes, the J's Racing ECU is a complete replacement, straight plug-n-play which will work on your model.

 

the J's ECU isn't programmable though and it isn't meant for your mods. Go with the VAFC2.
