Set the time threshold and opening time both to 1ms, and upped the percentage to 50%. Still nothing, so I figured I'd try working my way down. Set it at 75% and it ran fine. Dropped it a percent at a time until it died at 65%. Right now it's set to 70%, but I'll try lowering it again under ...

Re: Low impedance injectors not working with PWM
Lance,
The Delphi specs show them as 4/1 peak&hold, so I hadn't tried going above 30%. I'll try that tonight and report back. It would help if I had access to an oscilloscope, but no such luck.
Thanks!

Low impedance injectors not working with PWM
I'm running a 1725cc 4 cylinder, MS1 on a 3.0 board running a pair of Saturn TBI injectors (small Delphi style), one per driver. Wired the car without resistors, planning to use the PWM on the 3.0 board. But if I set both the opening time and timing threshold to 1ms like the instructions say, it won ...
