Default ASR OFF Light on and off after cam install

Just picked up my car yesterday after getting a cam installed. Now I realize that putting the car on the dyno will make the light come on and then it normally goes off after a few miles. Now the ASR off light randomly comes on. What could be the cause of this?

Have you had it tuned? Mine even after a tune tends to do it sometimes. Does'nt bother me much but I'm gonna work on it. I was told a while back on here that this can be taken care of through a proper tune. Good luck!

You might actually have abs wheel sensor going bad (totally unrelated to the camswap).

Sorry, didn't see the "tune." But as I said mine has a tune and still does it to.

Your P0121 error min and max map values are set wrong in your tune.

If you have different sized (diameter) tires in the front to the back, it will cause this problem as well as the ABS Inop.

Negative, its a problem with vaccum sensing at the map sensor. If the parameters have not been changed there to make that light go on and off it needs to be.

They are just diagniostic test so setting them so the light doesnt turn on will do no harm. Usually 0 for the first few columns should do it

I had my car retuned again, the min and max values were changed again. I still get this light. Looks like i'm just see if I can disconnect the bulb.
