Can someone help me with my AFR? I'm guessing the most obvious answer is that I need a piggyback system... but I recently decided to hook my Wideband O2 sensor analog to my laptop. I did notice that my digital gauge is off by a lot. It was reading mostly from 11.3-11.9 when I had the pedal to the floor and it was reading from 12.5-12.9 at idle.
Here is a graph of a session where I was shifting first through fifth gear. I wasn't kinda lazy shifting the car to try to separate the gears as much as possible to be able to read the graph better. When I was in gear though I was flooring it, except for 1st and 2nd gear due to traction issues.
My question is, if I were running a turbo, supercharger, or spray and had this graph as my result, am I okay? Or am I running lean?
Can't really read that cuz I don't know what I'm looking at but you should be running 11.0 -11.6 WOT (pedal to the floor). You should be running about 14s at idle. Now that's if you're turbo. That's all I can tell you.

Seems to me you are looking at the spikes going over 20afr. Those are probably DURING shifts. When you let off the gas, your AFRs will go thorugh the roof cause there is no gas in there, which is fine, cause your not reving your engine up.
when you are accellerating, your ARs should be in the 11s (boosted) and then as soon as you let off to slow down or whatever, your AFR will go full lean untill you slow down enough, or shift to the next gear.
that chart would be more helpfull if the bottom line was RPM or throttle or something like that.
