Hey guys I've recently brought an Evo 4 running a Evo 6 engine (supposedly) and it seems to be running the standard Evo 4 ecu and runs a bit off, will changing to the Evo 6 ecu make much of a difference? Dumb question I know, and also how can you tell what type of Evo engine your car is running? So I can be sure.

Tough question for sure. There maybe someone here that can intelligently answer this, but wanted to know if you belong to the MLR forum?

If not, it might be worth posting in this section of the MLR. Certainly many more EVO 4, 5 & 6 owners here

I can help you. If it's an Evo 6 motor with Evo 6 injectors (pink/red tops) then you need an Evo 5/6 Ecu. If you have yellow tops (Evo 4 injectors) you're fine with the 4 ecu.
