For the most part everything I see on this forum is for me7 and unfortunately for me my ecu is med9.1. I've been reading that they are similar and from what I can tell the acronyms are the same for the most part. I'm assuming most of the the difference is the di portion for injection timing, duration, and fuel pump control? From what I read if you max out your injection time it would result in fuel cut. How many ms can the stock fuel system support at redline? mk6 golf r for reference. Also, Im really interested in adding mpi if that's an option too, MPI fuel upgrades are just so much cheaper.
