Summary of change:
KTM LC8 engine. 4-stroke, 75-degree V2. 950/990cc EFI version has 24-2 crank trigger. No camshaft sensor. Problems is with trigger tooth reference table. I think this engine needs custom code and it`s very urgent. It`s hill-climb motorcycle and race is very soon!

Best regards Vems Dave ----- Thanks! I will do it tomorrow. I found shorter triggerlog file: http://www.vems.hu/files/ElbeEngineering/KTM_lc8_24minus2.triggerlog Config: http://www.vems.hu/files/ElbeEngineering/Config_KTM_LC8.vemscfg Dave, was it helpful or I have to get longer trigger log? ---- Hello Elbe Sorry i missed your edit (it helps if you provide a bit more text in the summary of change box so it stands out, just "edit" is easily missed) According to my review the engine should be able to run without any firmware mods; the longer triggerlog without IGN and INJ fuse should provide a bit more info on this, please keep spark plugs in the engine so i can see compression phases also. Review of triggerlog KTM_lc8_24minus2.triggerlog: * 24 minus 2 correct * odd fire engine with tdc at around tooth 14 and tooth 19 * rotation period around 180 msec for 360 degree * tdc time diff 232, 150, 236, 149 msec (roughly) * this translates to 220, 140, 220, 140 tdc crank degrees offsets (roughly) * it seems you might get away with delaying the second ign index using the spark delay function in base setup -> cyl separated spark delay, around 45 deg should do it. If you run into any trouble please let me know and supply new triggerlog / vemslog; i'll review and provide hints on how to proceed. Best regards, Dave
