When I look at your primary ignition map there are areas flagged for knock detection. I must be missing something else? I'm only bugging you about this because the issues fits if it is at least still using the fuel knock map, which you have zeroed (14.7:1 AFR). This would make it lean until knock w...

When I look at your tune in tuner pro I see the knock sensor box checked. I am not sure if Nistune handles that differently but it seems odd to me. Do you have another tune with the knock feature enabled or with the secondary maps in place? Yeah I have the knock sensor checked but I do not have any...

No Luck with the 0x0200 Map fix. That map is the Alpha-N map. It sets the threshold for the TPS voltage at which the ECU jumps to the last column of the Fuel Map. So it causes really rich conditions for a turbo vehicle when driving around casually hence why they say you should set this map to max va...

Thank you for the response and helping me out on this! When I look at your logs the switching point to go back to rich happens at the same RPM in two parts of the trace. What RPM is this red line at? http://www.dagengine.com/FORUMS/240/rpm%20switch.jpg It happens at different RPMs, and I think the R...

What RPM does it happen? It happens at any RPM when apply throttle. Any load I apply at any RPM causes the AFR to go lean and then back to normal. This is an S13 KA24DE which has the SCV Butterflies removed. Maybe the ECU is programmed to pull Fuel to account for the SCV at partial throttle? Check ...

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.
