Ok, I figured out what I need to do. I fixed the RPM issue and sure enough, I can tune!!

This is great news for people who want to tune themselves.

BUT it appears I've hit a cap. I have so much boost going into the system, I hit the 5v MAP sensor cap way early now, and the lack of fuel at 100% duty cycle is the cause of the detonation... and the timing is way advanced at that point. I have my ECU tuned by powerchipgroup to compensate for a 25% overdrive pulley, but I think that tune is having the same problem... the fuel just isn't there!

WHAT THIS MEANS: I need larger injectors. I've been in contact with a fuel injector builder that can possibly change the cores out of my stock ones and upgrade them to guarantee fitment in my fuel rails and manifold.

FOR NOW: I'm back to using the ASP pulley, and I was able to tune it better to allow for better use of my headers. AND IT ROCKS! So, sorry, my ASP kit won't be for sale in the next few weeks, until I can get these custom injectors.

BUT: I am excited because as far as I know, I'll be the first M112 engine that is pushing so much through the system that I need upgraded injectors.

As always, I'll keep you all posted!

P.S. I'm also sending my ECU back to powerchipgroup to see if there was a mistake first. If it's not, and that's as good as they can do, I'll just have them set it back to the factory fuel mapping, which seems to be very forgiving anyways, and I can tune the rest with the Apexi.
