Hi guys

I'm building evo 4 and going to use reflash-able ECU, currently have 2 options

Option 1: EVO 8 ECU - need to re-seat 5-6 pins on stock harness and ready to go
Option 2: EVO 9 ECU - need to rewire everything (79+ wires) and make some special harness to connect 4 plug evo 4 harness to 3 plug evo 9 ECU

some says that evo 9 has much more benefits ruther then evo 8 ECU, so before going to Option 1 which is easy way, tell me what benefits has evo 9 ecu comparing to EVO 8 ?


thanks for your help

 

If you are going to run speed density, IX ecu's are known not to have common jitter problem. Otherwise no real difference in functions and I have few friends running sd mod in early evo with e8 ecu and those work just fine without jitters (or then jitters are so small that they never noticed it).
