Trigger related page for MembersPage/EricN
truck is a 6 cyl. I am firing cop coils and using a distributer mounted trigger wheel. Tooth count is dependent on what sensor I get working
Board is a v3.2 serial number=110

Going to try this for now.
- so much for that idea.
This page hopefully all garbage. I cant get the input trigger to stop cutting out (happens at any rpm all the way to redline) no matter what I try.
OPTICAL TRIGGER DROPS OUT LIKE VR DOES
Built an optical trigger. 6 teeth, set to coil type ignition. Use rising or falling edge makes no difference. Use filtering or not, makes no difference. Trigger drops out at any rpm (tested up to 4000) is worse at low speed. Loose fuel pump, injectors and ign.
Used signal generater, run at 250 to 500 rpm according to lcd. Fuel relay cuts out in the same manner. Tested signal at atmega128 pin 29, looks clean.
Is there anything config related that could cause vems to cut out? Keeping in mind the test bench has no sensors hooked up at all, just a input trigger and fuel pump relay.
- fuelcut_min_kpa
- fuelcut_max_kpa
- TPS > 60% (at cranking, that is RPM / 100 <= cranking_thres )
- MegaTune log could help
- don't forget mcd,mct either (always needed to reproduce)
- are the GND and (at least 3) GND5 signals all connected ?
