I just bought a zctron scanner for my 92 LT1 how can i tell in the numerous readings the air fuel
ratio or if the car is running lean or rich ? :conehead
Sorry, I use diacom, but it should be similar? You want your BLM and Int at 128 as much as possible. At WOT it will show 128 on both, then look at the O2 sensor voltage. I know this is brief, but you need a book! Check out "How to Tune and Modify Chevrolet Fuel Injection" by Ben Watson. It's a wealth of info.
