Here's a 3rd gear data log of my second nitrous pass yesterday.(forgot to log the first pass) Too bad I didn't have time to mess with the jetting before they told me I was done for the day. I'd say it's a "little" on the rich side! :gives:

dear lord. over 10 ONCE! hahah.

might want to fatten it up some. looks like you're running out of fuel.
 
Damn you should see big gains leaning it out...prolly even fatter in 1st and 2nd gear I'd imagine with less load on it.

Who knows, the car never seems to pick up lol We pulled fp off my nitrous fuel system but we needed to change the fuel jet size and didn't have time to get that involved plus I was done for the day. Wheelz wanted to get crazy but we didn't want to do to much after the first pass since I didn't log it so we just pulled fp out. Looking at the plugs we knew it was rich but the log tells just how much. It was pretty much the same through all the gears, never above 10:1 really.
 
good lord! you done for the year or are you going to try one more time? Ubly still open isn't it?

damn. Yea i'd say you have a little room to lean on it :lol: Still doesn't beat CableGuys car, runs 7.5:1 coming into boost leaning out to 13:1, now figure that one out!

What type of wideband/logging setup are you using?

Wasn't aware of any widebands that will read much lower than 9.0:1 (actually the equivalent lamda which is just converted over to gas for most software)...mine bottomed out around 9.2 and that's a bosch sensor...what were you guys using? I wouldn't trust anything below 9 on any wideband anyways...

Ubly is closed so I'm probably done for the season. Who knows maybe I'll make Lapeer one more time, I'll just need to get my fire suit to make Ed happy. lol
 
Cool! Let me know and I'll come out and tape it.

Innovate LC1 w/ Bosch sensor. Worked fine in my car so I have no reason to believe something was wrong with it.
