gear help

I wanted to see if I can pick your brains a bit. I have a 2001 camaro ss m6 without traction control. I did a gear change for a 3:73 with limited slip. The minute I did the change my abs stopped working. I was told that's because I need to get my ECU reprogrammed. I also went from a torsen differential to an auburn. I have no idea what it is but my breaks don't work right now. My ABS INOP light came on as soon as I did the swap. Would a tune fix this problem?

A cheap hand held programmer would do that for you. If you have a tuner, it would only take him a minute to correct the gear ratio.

I'd be interested to know what you come up with. Did you change the whole differential carrier? Did the new one have a tone ring for the ABS? Cars without traction control use a speed sensor in the rearend and cars that had trac control use speed sensors mounted near the rear brakes(correct me if I am wrong on this statement) So I think that if you got a carrier for a car that had trac control, that could be the problem. When I changed from 2.73 to 3.73, I never had a problem with the ABS, just the speedo, which is changed with a tune.

A tune won't fix your ABS problem. It only corrects the speedo. With the ABS INOP light on, your brakes will work like normal non-ABS brakes. You just won't have anti-lock. So if your brakes don't work, then you have more then one problem.

So I finally got it fixed and running. The occurred because I changed my differential from a torsen to auburn and it didn't line up with the sensor on top of the casing. The auburn was a bit shorter and caused my abs to go out. I switched the differential back and it's all good now.. Finally I can drive her!!
