You are quite above that here.

The fuel limitation that others have suggested doesn't appear to be hardware based. There are some adjustments I made to injection timing/phase and PI/DI split that got me around this "fake" limit. In terms of logs, I have both PI/DI injector under 80% DC and fuel pressure stable at the target level. There is, quite literally, nothing suggesting that i'm even close to the limits of the fuel system. PI IDC can be dropped further by tweaking the PI/DI split but it looks like the engine likes plenty of PI at high boost.

Every now and then, the ECU triggers what appears to be a 7200rpm rev limit. That's what Rev Limit B is set to from the factory. I raised this to 7500rpm but it still throttle limits at 7200rpm. Working with ztan on figuring out the underlying logic. Initially I thought it was a cut caused by lean-run but there is no evidence of lean run:

Interesting. I saw a thread with ztan mentioning he was doing some investigation for you. Looking forward to your results. I'll be doing some work on an oft350 setup here locally this weekend. I'm trying to convince the owner to go e85, and this is a nice step in the right direction.

So many great options for FI now, its awesome

amazing
but not easy to buy OFT350 kit here, i'm wondering the OFT tablet can tune Greddy T620Z/T518Z turbo kit?
