Did you know that the PFC actually switches over to both injectors at about 47% duty cycle even though we are told that it is 40% and the DL injector Pri/Sec Transistion (%)setup is at 40%. Maybe an Apexi program error? That is why my PFC tuning notes and I have posted that you should change it to at max 30% which will then logs at 37%. Helps to a smoother transition even with stock injectors.

Did you know that the DL injector Sec Transistion (ms) is too large and what we were told on how to change it for larger secondaries was wrong. For 550 primaries, no matter which secondary size you run, use .100. Actually going smaller does not have any affect as the programming limit has been reached.

All of this is in my notes along with logs that prove this infromation.
