I have a toyota 22ret i put a megasquirt 2 v3 on. The stock harness has resistors between the battery and the injectors. My question is would the resistors cause a problem when tuning the INJECTOR OPEN TIME and PWM TIME THRESHOLD it only will idle when those numbers are above 1.5 - 1.7. I really dont want to burn out my injectors so is it safe to run the higher number settings with the resistor pack in line or should i take the resistor pack out?
thanks

Re: Injector resistors
With the resistors in place, it should be impossible to burn out the injectors.
However, there are theoretical benefits in removing them and driving low impedance injectors directly - that is the whole purpose of the PWM flyback damping circuit. My MS has been driving low impedance injectors directly for 4 years with no problems. But do follow the tuning instructions to the letter.
