does anyone know what type of programmer to get to control air fuel ratios and timing that would work for my car?

im concernd cause im runnig NOS and i heard that you can change the timing. But i also heard that tcs adjust the mixture automaticly so it wouldnt matter. And can those programmers turn off CEL?

 

anyone?

 

You want to advance or retard you timing?

You want to adjust your air-fuel ratio?

Any stand alone can do it. E manage can do it to an extent, Emanage ultimate can do it, and Uni Chip can do it to an extent.
