It is the strobe that shows half of what´s written I was tuning the car last night, and the advance seems to be off: * strobed at 10degrees, so this is right * if I write 40 degrees in the megatune sparktable it changes only +15 crankdegree (to 25 BTDC), not +30 crankdegree (to 40 deg BTDC) as it should ** measured on the crank, of course (not on cam) ** some '''smart strobes are confused by the wasted spark ignition, this actually happens quite often'''. ** Can you do '''measurements the 40deg and 10 deg with same strobe settings''' (or a dumb strobe, and see angle difference on engine ?) *40deg is 25deg measured, and 10deg is 10deg measured '''Can you describe the strobe and its usage in great detail ?''' * type * switches * what knobs * display * ... ** the timinggun is about the oldest that can be had, there is no buttons on it, i will check if i can see a name on it, but i think it´s around 20-25years old. there is just 2wires for power and gound, and a 3rd with the inductive feeler to put on the ignitionwire. ** if it lights up at the time of spark (seems likely if it has no buttons) and you read from the rotating crankshaft, than the chance of getting it measured wrong is minimal indeed. ** Want to test with Sami's 1.0.77 compile that Jorgen drove for quite a while now and found good. Anyone have that firmware image ? * yes i will give it a try, anything to make it work:) This way earliest is 37.5 crankdegrees BTDC (max commanded ignadv is 63.75 degrees. ---- This is from the helpful [http://vems.hu/www.vems.co.uk/forum/index.php?topic=480.15 VEMS FORUM] There are trigger errors when cranking, though the wiring seems OK * and i cant seem to find any info, regarding the "advanced filtering" settings, if that maybe can help filtering that out ** GenBoard/UnderDevelopment/FirmwareChanges, (toothrel_normal and toothrel_missing ) multitooth advanced filtering so thresholds can be set for what is considered as long-gap (eg. 125-420%, in actuality 60/30 and 90/60), and what is short (eg. 16-100%, in actuality 30/90 ). * car will sometimes backfire when cranking ** the "crank minimum usec" shouldn't cause that (you can set it to 370 usec, that is 20 degrees at 9000RPM, or you can even try 0). If it's too high, high-RPM triggerinput will not be believed Link to some info to how ms extra does subaru, can any of you see what the vems is missing to filter the noise, if this ms extra setup works, interesting that they '''trigger on raising egde''' ** MS trigger on falling egde!! http://www.msextra.com/ms2extra/MS2-Extra_Subaru.htm Another link with a sulution to ms setup with the exact same symtems as i got when cranking. http://www.msextra.com/viewtopic.php?f=91&t=28092 ---- We scoped the oe dwell time, and that is 3ms. http://img.photobucket.com/albums/v41/Denmark/NewFile_07.jpg ** Now cranking 200 RPM (OK), ** car runs fine, when it is started, only cranking is out of sync ** but sometimes backfires during cranking? **this is worse when the weather is colder, and better when warmer, like now. ---- '''Crank and camsensor signal scopeshot''' - looks OK.
