update:
Rich from Viper Tuning put my ECU back to stock and solved the 16985 error and Viper Tuned my TCU.
He noticed my ECU/TCU was remapped but couldnt say by whom.
quote:
The Map was not great, did not do much with fuelling and ignition was low so you've not lost anything imo, stock map would be better!
TCU map, not quite sure whats going on there! Best be gone with that!
It will be send back tomorrow.
So im very happy with that and i hope to have a stage 1 Viper Tuning map soon...
Rich thank you so very much for your effort and knowledge!!!

If you can't go to the track, bring the track to you.
