1/2 Bar OS Enhancement
In the VCM enchancement tab of my tuner the 1 Bar SD is "not available" while the 2 Bar SD is simply "not applied". Is there a reason for that?
This car is N/A and will be so for the coming future, so I don't see a need to do a 2 Bar tune. Is there a way to just do the 1 Bar enchancement? And if no, would there be an issue to run the 2 Bar tune on a 1 Bar sensor?
BTW this is a 2006 E40 PCM.
