Wheel Diameter Relearn
Hi All,
Does anyone know if any of the tuner software options have a wheel diameter relearn option, and if so, which ones are recommended? Background - I am going with 18's for track, and the tire I chose to pair to the rims results in a 2" diameter reduction. I am not as concerned about the speedo and mileage as it is only for track use, but I have heard (in non-GM cars) that nannies can get triggered and while it would be annoying, one type that scares me is the car triggering into Ice Mode, negating the ability to smash the brakes. I'd be happy to have folks here tell me this is not a concern at all for these cars, but I'd prefer to know if the diameter re-learn is an option.

Not an automatic "relearn" per se, but HP Tuners does allow you to change the tire diameters separately for front and rear, see below.
