Default I put 28" tall tires and now the ABS INOP and Brake dash lights are on.

I put a set of 28 inch dia slicks on my car, but I still have the stock wheels and tires out front. Now the ABS INOP and Brake dash lights stay on.
I'm sure the problem is having different dia. tires front to back.

Is there anything in the tune I can change to turn these lights off ?

I tried a search and still haven't found a fix.

When I check for DTC via HP TUNERS nothing comes up. I assume the ABS computer is seperate from the ECM.

ABS is its own little world and on F-bodies it gets pissed if tires
are about 10% different in diameter. Nothing much (besides an
ABS delete) you can do about it. It'll go off again when you put
the symmetric street tires back on.

You could look for some tall skinnies to match.

Thanks Jimmy.

I guess I'll just have to ignore it. Until I put my street tires back on the car.
