I had ran the engine with ignition set 4 teeth, 4 missing and had the same performance , so I used what others had posted in their msqs ...

Here is a datalog on the stim. Cranking, run at various rpms. Comparing the rpm to SyncStat you can see were the processor doesn't respond to all inputs from the rpm pot at low [starting] rpms , this is also how it behaves when in the car. Matt Cramer suggested I check the BIP 373 pins [Q 16 ...

I changed to a stock Dodge coil known to work before datalogging , changed msq accordingly. John.

MS2 v3 2.905 I switched to direct coil control and still have no spark . LED tester blinks while cranking, stays solid with key on when testing at OPTIN jmp but no longer lights at U1 pin 14 , ground is proto area Gnd . Fuel pump ran while cranking after switching to direct coil control and test LED ...

MS 2 v3 ini 2.905 Worked fine on the stim, has an input of up to 4.05 volts from the hall sensor. I checked the output circuit from the DB37 to the MSD-6 box and have voltage 11-11.98 volts backfeeding to DB-37 pin 36. Resistance from carbody grd to pin 36 is 139.4 ohms. Resistance from MSD-6 case ...

MS2 v3 ini 2.905 I have a hall sensor with a 4.05v input signal at the OPTIN jumper and also at pin 14 of JP2. At pin 17 [JP2] and JS10jmp there is no signal when powering-up or cranking . The BIP 373[Q16] has no input signal ,ground is good , the center pin has a constant output of 11.98 volts when ...
