Car Dodge Viper 10 cylindre ODD FIRE Could be Thorbjorn Engdahl that made this car. http://www.vems.hu/wiki/index.php?page=MembersPage%2FThorbjornEngdahl%2FVIPER Can Vems control this car specially thinking of ignition. The car is running but do not sound well. also burned a engine early this year. Car is now running wasted spark Config http://www.vems.hu/files/MembersPage/PeterJensen/Viper/viper_v3.3_u011200-A-2018.10.26-16.49.23.vemscfg ---- Hello Peter, Yes Dodge Viper v10 is fully supported using the stock ignition system (which is indeed wasted spark). Best regards, Dave - can any body verify the config Peter did upload. the firing is not accurate on some cylinders! i think the ignition setup. Best regards Troels ---- Hello Peter/Troels, I have reviewed your config "viper_v3.3_u011200-A-2018.10.26-16.49.23.vemscfg" and there are indeed some ignition configuration problems there; To avoid any unneeded verification (or confusion) please apply the setup from configlet "Dodge_Viper_V10_10+4_Camsync". If you upgrade the firmware to 1.2.38 (latest stable), wire the coils as follows (also included in configlet txt): * ec36, pin 33 (10) = cyl 1 + 6 * ec36, pin 34 (20) = cyl 5 + 10 * ec36, pin 35 (00) = cyl 8 + 9 * ec36, pin 36 (30) = cyl 4 + 7 * ec36, pin 24 (60) = cyl 2 + 3 You'll have confirmed good starting point from which to continue. I hope this helps; if there are any further questions, feel free to ask. Best regards, Dave http://www.vems.hu/files/PeterJensen/v10%20starts.vemscfg hi. now engine starts but only on some cylinders trigger angle is not the same as in the configlet. does any body know the trigger phasing cam vs crank? it fires 3times in a row one some cyl. best regards troels Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
