I've got a problem that is causing me all major of headaches. Engine is:
Custom 36-2 trigger on the crank
Honeywell 1gt101dc hall effect sensor with a 1.3mm air gap, wired to 12v
1230cc low-z injectors
Splitfire coilpacks (wired in wasted spark)
MS3 v3.57 with ms3x.
The jumpers and pots are set up according to this:http://msextra.com/doc/ms3/ignition.html#geartooth
Basically, during cranking I get perfect rpm. As soon as the engine fires it starts getting sync losses. Changing the pots and/or the jumpers around makes it only worse. With boths pots fully counter clockwise i get no rpm signal at all.
I've scoped the signal coming from the sensor and its great. The signal at the cpu isn't so great though. The only thing i can think of is that the injectors are creating terrible noise????? Any thoughts?
Attached is an msq and a log of it trying to idle.
Any help is greatly appreciated. It's driving me nuts!!!!
