Summary of change:
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. * firmware 1.0.30 * [http://www.vems.hu/files/MembersPage/NanassyPeter/ClonInstallStartUp/mct.txt tables ] * [http://www.vems.hu/files/MembersPage/NanassyPeter/ClonInstallStartUp/mcd.txt config] * mdd0c logs (zipped together) http://www.vems.hu/files/MembersPage/NanassyPeter/ClonInstallStartUp/mdd0c_logs.zip Because of the too much unknown factors ,we will install my known working 5 window camHALL triggered ECU,and try to fire the engine up with that.Any comments appriciated. It's good that you published config and mdd0c logs. However, * if you have sparks and rpm it might be something else than a trigger problem. * so '''take logs with MegaTune''' (remember to say bye after fiddling in Man mode, taking mdd0c log for example). ** we'll watch for fuel pulsewidth (possible fuelcut due to TPS>60% floodclear at cranking or kPa fuelcut, whatever...) '''NO,i checked this,there is PW''' * is the ignition right where you like ? Do you have a lamp? I remember this engien has a custom crankhome VR position, a few degrees off. ** if it's just 2 degrees or so, the normal procedure of varying trigger tooth or ign_tdcdelay should work well * is the fuel system working ? fuel pump, fuel pressure ? '''Sure,its working,there is a LOT OF fuel i the cylinders''' Can u please clarify to me, are the trigger logs good?Is this a trigger related problem?DO I NEED TO CHANGE THE CRANKHOME VR POLARYTY??? so my checklist, HALL measurements Crankhome VR polaryty (WHATS GOOD??) MegaTune log
