Rotary injection firing angle

Hi Zack,

The idea with injection timing is to have the injection pulse finish just before the intake valve opens.

One method of determining the correct injection timing is to set the tuning timing (any number), tune the engine, then adjust the injection timing so that your AFR increases. At the point where your AFR is at its richest is the best injection angle. The engine will then need to be re-tuned at the new injection angle.

The PCLink help does have some more information on the injection timing settings, see PCLink Help > G4 ECU Tuning Functions > Fuel > Injector Timing
