2.2 s10

[SW1911]

There are get around ways to tune the alpha n setup in this pcm and works reasonably well. Is it correct? absolutely not. I am still daily driving my 98 S10 2.2 that has been turbocharged for the last 6+ years with 15-20 psi and maintaining the correct afr under boost and normal driving conditions. So have quite of few other people across the internet. Get the 2 bar map thinking out of your head when working with this pcm.

you have peaked my interest with "the incorrect way " is this something you would be willing to share just for comparison ?

thanks
