K20 swapped Elise S2 - Hondata Kpro V4

Engine is running on for around 30seconds after ignition key is turned off, I can’t figure out why!

Could be related to wiring/ECU voltage, alternator or mechanical issue but so far I have not been able to get to the bottom of it.

Any tips or ideas as to what could be causing it please?! Can I diagnose the ECU or anything else?

Thanks

Try the ECU in a known working vehicle and see if it works properly. If it does, then you have a wiring issue that needs to be resolved.
