Cold/warmstart learning.
Quote from Deleted user on September 25, 2019, 3:44 amUnfortunately no and here is why. All EFI, aftermarket or factory, use an O2 sensor to adjust and learn. The O2 sensor is only accurate and working until after the engine is running and the sensor has warmed up. Therefore there are values in place that create a base tune for cranking and Warm up. For some those values work, for others changes must be made.
Expand on what issues you are experiencing and also describe the engine build. I may be able to lead you in the right direction.
