I would greatly appreciate some help with my friend's car please, it's a 2002 Camaro SS manual trans. stock and he recently installed some big rear tires on it for drag racing. (they are about 27" M.T. ET streets). Of course the speedo became way off and the ABS light came on, so I typed in the exact tire size into the speedo calculator and saved / flashed it, but it still has the same problem.

The change that I made in an effort to fix it was:

{H0101} Vehicle Speed Sensor Pulses per Mile, changed from "47020" to "43108".
{H0104} Trans Output Shaft Revs/Mile, changed from "805.1953" to "2535.7856".

Since it does not work I am wondering if other tables need to also be adjusted. Please advise if you can, thanks!!!

The ABS controller needs to know the tire size, but it can only be flashed by TechII/dealer.

Is he running skinnies on the front? You can run 26 or 28in rear tires it's usually the fronts that cause problems.

Hmm, no skinnies - stock fronts. I wish I could fix this somehow with the tune... The car looks a lot like yours! :)
