Summary of change:
Need help to get this “nice” jap trigger working Car Toyota Engine blacktop Cas distributor 4 spots on shaft * tooth width == 180 crankdegrees ? Problem: When setting up ignition to 17 degrees BTDC at 1000 rpm its only 7 degrees at 5-6000 rpm so its sliding almost 10 degrees. '''Measured how ?''' * Seen this problem long time ago but due not remember what caused it. ** wrong edge ? * tooth width? ** 180 crankdeg, seems good * does validate warn about strange values ? ** apparently nothing relevant * is RPM smooth (or fluctuating) ? * '''MAYBE TIMING LIGHT triggering on wrong edge ?''' ** is it a smart timing light ? * Logiclevel coil ? Maybe the coil firing on the wrong edge ? * maybe the wheel changes position ? ** cambelt sloppyness + mechanical hysteresys ? ---- Triggerlog 1 17 degrees http://www.vems.hu/files/MembersPage/PeterJensen/toyota/v3.3_n004171-2012-09-26-15.53.17_17degrees_.triggerlog Triggerlog 2 27 degrees http://www.vems.hu/files/MembersPage/PeterJensen/toyota/v3.3_n004171-2012-09-26-15.50.09_27_degrees_.triggerlog ---- Log (Config missing) http://www.vems.hu/files/MembersPage/PeterJensen/toyota/ ---- '''Bench Testing Results''' We ''benchtested your setup today''' with 1.2.6 firmware and scope. It '''behave perfectly, we didn't find any "ignition sliding"'''. Ignition seems to fire at good times at any RPMs. For example at 1000,3000 and 5000 RPM (with sparkadv locked to 25 BTDC), ignition angle is ~55 degrees (TDC after the trigger is 80, so 80-25=55) as calculated. http://www.vems.hu/files/MembersPage/PeterJensen/toyota/1.2.6-v3.3_u004521-2012-10-01-13.50.42.triggerlog http://www.vems.hu/files/MembersPage/PeterJensen/toyota/1.2.6-1000-3000-6000RPM.logicdata.zip
