Hey guys, on the way to the track last night my SES light came on (either my new gas cap or my MAF). Being the paranoid person that I am I stopped and re-set the CPU to make sure that the light would go out and all was ok. Then I drove about 100 miles on cruize to the track. My first pass the car was a dog. Second pass it picked up 2mph, and third pass it picked up 1MPH. Is this normal after a re-set? How long does it take for the cpu to learn again?

TIA,
-Nick

 

Thanks!

 

This may mean nothing but when I put on my cat back ( Borla ) It took about 800 miles to adjust. <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />

I believe it usally takes about 100 miles of regular driving for the pcm to relearn. It needs to see different fuel cells, meaning different engine loads and speeds to learn.
