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

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):

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
