will the ep3 ecu run in a rsx base....they both run the A3, only issue i see is that the ep3 uses EPS(electric power steering) and the rsx does not. also that the ep3 has the metal manifold and the rsx base has the plastic, so i was wondering in putting an RBC mani with the ep3, which i assume the ecu gets rid of the dual runners the base rsx uses. can anyone chime in if this will work thank you in advance

 

Well it will run lean with the RBC. Why can't you find another base RSX ecu? What happened to yours?

 

If you're going to install an RBC manifold, just buy Kpro too.
