I put in a new fuel pump on Saturday as my 20 year old stock one was getting quite tired. With all the extra fuel my tune is completely shot. I did a good bit of datalogging today trying to fix it and that got me thinking... If I've got time increments, and RPMs, and a gear calculator I should be able to calculate very accurate 0-60 and 0-100 times, even come up with a reasonable estimate of a 1/4 mile time.

So I went out and datalogged a 0-115 run. Not to sound like a ricer, but it certainly wasn't a great run, and the tune was worse than I thought, and I spun really bad, and then I bogged, and I had a full tank of gas, and.... you get the idea. Here's what I came up with:

0-60: 4.75
0-100: 11.21

I attached the txt file if anyone wants to look at it. You can see where it was spinning and I had to back off for the tires to catch, then you can see where it's missing a few times at higher rpms and I'm actually losing speed while on the gas. Maybe it's just me, but I find this stuff really interesting. Toward the end you can see time and speed and get a pretty good idea where the 1/4 would be, somewhere in here I'm guessing...

13.133 109.95
13.274 108.55
13.426 109.83
13.555 111.28
13.688 109.23
13.839 110.71
13.978 111.61
14.115 112.75


I'm gonna do it again in a few days with less weight and a better tune, hopefully I see some significant improvements. :thumbup:

from the current mph youll see mid to high 12's et's.so with a new tune wrapped up i see bottom 12's at 115-117


*edit whats up with the tp going dead at certain points? I mean you can seen when you shit but some times it goes down and looks like it stutters or doesnt open up fully

The launch was horrible. I spun really bad at part throttle until I just completely backed out of it (to 5%) and got back in it. Other than that it's at 100% except for shifts.

I'm sure I will, it's come a long way already today. I couldn't take it over 1/4 throttle this morning.

Thanks for the comments guys. I was really disappointed when I started putting the numbers together, but the more I look at it, I think it will be fine once the tune is worked out.
