Turbolarry - Drag results with S-AFC - 12.83@106.3

[Warrtalon]

I went to the track with the settings left over from my 3rd log in the previous post. Interestingly, tuning the car on a 3rd gear pull from 3-7k rpm was nothing like tuning during drag races. I learned some VERY VERY interesting facts when reading my logs after my runs tonight:

1) I had _0_ readings below 5400 rpm. I had no idea how high the RPMs were when I shifted each gear. From launch all the way to the end of 4th at the traps, I never went below 5400 rpm as far as I can tell. It's possible I went a little lower due to the delay between readings, but it certainly wasn't much lower. So, when tuning for the drag strip, I only need to worry about the 5-7.5k settings it seems.

2) I was rich, rich, rich with the previous settings while in drag mode. I was at .95v or .97v in EVERY gear at EVERY RPM on EVERY run tonight. I was only making very slight adjustments (1-2% at each NE-point) to be safe, but I apparently needed to take much more fuel out than I anticipated. My MPH went all the way up to a max of 106.3, so I am pretty sure it was working, but I _STILL_ had _0_ readings of .91v or .93v. I was simply amazed, but also a bit scared at the same time. I really did not want to keep leaning it out more and more without a wideband to verify the AFR was well below 12.

3) Despite being fairly rich, I at least had no major increase in richness at the higher RPMs like I did when I dyno'd without the S-AFC. Because of this, in my opinion, my timing advance was VERY smooth and right where it needed to be. I was tempted to throw in a few gallons of 112 octane and lean it out some more, but the lines were long, so I just went home. I was very satisfied with the 12.8 and clutch that didn't smell funky.

Believe it or not, I have never driven at a drag race before.
12.8 with a filter and an AFC I think is good though.
Seeing that your RPM's don't drop below 5400 maybe load your Ne points higher for more high end tuning;
1K, 2K, 3K, 4K, 4.6K, 5K, 5.4K, 5.8K, 6.2K, 6.6K, 7K, 7.4K
Just an idea for the drag races...?

Oh yea, don't forget to enter that time in the 1/4 mile times;

Wow, get your ass to the track for some baseline numbers!! I don't plan on going often, but I do want to know where I am at certain waypoints (stock, stock+S-AFC, S-AFC+MBC+Exh, etc.).

Yeah, somewhere in another post (maybe on EvoM), I said that I should do the same thing...shift my NE-points up so that I can get max tunability from 5-7.5k. The only problem is that I have the first S-AFC (left over from my Talon), so only get 7 total NE-points at 500rpm intervals. The best I can do is 5k, 5.5k, 6k, 6.5k, and 7k. I plan on doing that for all future trips to the track...

ldstang50's idea (if still on stock injectors);
S-AFC Troubleshooting

It's a shame too because Fontana (California Speedway) is 20 minutes from my house. Gotta love the married with children life.

Yeah, this was my response to his suggestion: "I know what you mean by changing the ne-points for higher rpm so that you have more tuning. I have already changed my hi-throttle points for this exact reason, as I agree that it gives me more tuning points in the rpm ranges that need it most."

I had already begun to do that, and had it that way last night with these NE-points (3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7). Next time at the track, I'm just going to adjust upwards one slot, so that I cover 7.5k, but not 3.5k.

I filled everything out, but it never shows up in the list.
