Nistune strange injection time issue

Postby ilya240sx » Thu May 17, 2018 9:14 pm

Quick overivew of the car:
- S13 KA24DE
- T28 Turbo (wastegate pressure ~5-6 PSI)
- Stock KA24DE MAFS
- Subaru STI 550cc Injectors (1050uS latency)
- Looking to get 200HP
- S13 ECU with Type3 Feature Pack board

Im having an issue where the injection time is slow to catch up with the fuel map. When doing full throttle run, the AFRs stay lean until, what seems to be a random point, then step down and get to where they are supposed to be (see picture). At that "step" point, the car finally feels like it has power. Looking back at the log, you can see the injection time doing a massive step up (orange line), at which point AFRs richen up and get to where they are supposed to be (green line) and the car comes alive.

Has anyone ever encountered this?

Thank you
