I use autotap with the gm enhancement so I can log knock retard. I use JET DST to tune my 96 Vette. I have HPTUners for my camaro and pickup. Bjankuski is right you can use hptuners to scan but you only get the 18 generic parameters which in most cases is ok but you don't get knock retard.

I got mine from thunder racing. It was $199 for autotap and $99 for the gm enhancement. The nice thing is you can use it on anything 96 or newer for the generic parameters and anything 96 or newer with all the parameters with gm vehicles.

thanks for the info. Is there a specific autotap part number or version to use? The gm enhancement allows logging of enhanced sensors such as knock retard?

Autotap ATU is what I bought it has a USB cable opposed to Autotap ATS which has a 9 pin serial cable. I will PM you a link to the site I bought it from because I am pretty sure they are not a forum sponsor.

Also the gm enhancement opens the door to about 250 gm enhanced parameters to scan. The only reason I got it was knock retard. It will be nice if I have to scan some newer stuff with the drive by wire.
