low Z injectors only running in high Z mode

Post by lt1will620 »

so i finally got my twin turbo lt1 up and running on the megasquirt II, but i have one question, im running accell 160lb/hr low Z injectors, but it will only run with the settings , pwm current limit at 75%, correct for low Z, however, when i set the pwm time threshold to 1.0 ms as the MS site says it just fires and then quits, so i went back to the 25 ms setting that was in it, and it runs fine...will this be okay since i am using the current limit setting?

everything is installed correctly, i still havnt measured the resistance, but when i changed the time threshold to 1.5ms and the current limit to 80%, it now runs, but with poor throttle response. these are very large injectors, so maybe it just takes more voltage to keep them open
