Default Tuner Pro RT data

Hello,

I just got the Tuner Pro RT software working on my 1989 6 spd. Corvette.
I have two questions.
1) analysis - is there someone or place that can help me analyse the data. My O2 sensor was red and over 900 all through the test drive.
2) changes - what hardware do I need to make changes that will improve the car.

Thank you
Joe

900 normally meens your running rich, did your data show you were in closed loop.

Yeah....And do you have any modifications from stock?

If not, this is an exercise is diagnostics...vs analysis. Injector failure would be at the top of my list. (If one/two fail on the driver's side (O2 side), the rest will over-compensate and drive it very rich.

If so, adjusting injector size and/or MAF tables is the first step.
