I have a V1 Flashscan and need to do a CKP relearn. With the last set of modifications to the engine I had a dyno tune done on the car and the tuner used HPTuners with a 2 bar OS. When I go into the bidirectional tab of the EFILive Scan software there is no option on the dropdown for the relearn. I'm assuming the issue is the with the HPTuners 2 bar OS in the ECM I can't use EFILive to perform the relearn? Any other options? e.g. can a TechII/III at a dealership still perform the relearn with the custom OS or do I need to get my hands on HPTuners?
p.s. the place that tuned my car is several hours away so I can't get their in a practical way
Car is an '04 Cadillac CTS-V (original LS6 ECU) with a Magnuson supercharger added.
