tuning questions

[dboosted1]

I just installed scanmaster and have a couple questions. When reading 02 volts should they jump around or just gradually go up/down. When I am driving they fluctuate greatly ex. 200, 070, 300, 550 . then when I give it gas it moves slowly up.

Im thinking maybe a new o2 sensor?

I am glad I got it because when i got on it my max kr was 15.0! I have a afpr, walbro 340/hotwire in the houe and they will be on tomorrow! I just hope I havnt caused any irreverasable damage driving it before knowing how much I was detonating.

Scanmaster looks like a great product and they even sent a page with basic tuning guidlines, I wish I would of bought it a long time ago

02s jump all over the place. What you want to watch is the 02s at wide open throttle. One the www.gnttype.org page there is a basic guidelines page that has most of the operating perameters for our cars. Print it out and stick it in your glovebox.
