Auditrigger on a inline 5 cylinder Audi engine,but now only with distributer,and 1 coil.

After 16 hours of hard work we tried to start the engine.Everything looked great,we had RPM signal during cranking,we had spark (at the right cylinders),and injectorclicking too.Unfortunately the engine did not fired up,after 4 hours of continous problem searching,we did not found the cause of our sadness.We tried different ignition and fuel settings.I also realised that the car dont really want to pull vacuum under cranking (in the vems,map sensor),tough i can feel it with my hand.(no plumbing,only throttle body).Note that the car was running in the past with dual K-jet without problems.We also checked Compression in the cylinders,and they are good.

I formatted the binary logs with /svn/firmware/utilities/vemslogger/auditrigger_logformatter <mdd0c_3.log >mdd0c_3.txt and watch:\nÿ1ÿ

The offending crankhome VR pulse typically comes after 1 crank rotation (==0.5 cam rotation, 2.5 events) instead of 2 crank rotations. So that means : check your cam-HALL ! that is responsible to mask every second crankhome VR pulses

It's good that you published config and mdd0c logs. After trigger hammered, don't forget

Q

Is it possible to just ditch the camsync HALL signal and map the ECU for only crankVR signals?This is just a theorethical question,tough the car now uses distributer,so full sequential running is not needed.Can the current Auditrigger firmware handle that??
