Ok, as I stated in the previous thread, it was not my night. I don't know what was up, but I could not get my act together. Bad shifts, bad launches, big time tire sway, poorly prepped track...whatever you can name, it happened. :shrug:
However, I knew that everyone was waiting on these results, so I kept plugging. I made 6 passes total. The first pass I launched, grabbed second too fast (grind), then missed third! Wonderful. I also lifted when I missed third and just threw in the towel. I lost that slip.
The second pass was going ok, until I had really bad tire sway...so I had to lift and pedal. I barely got into 4th.
Here is that pass:
Third pass was ok, but the 60 foot sucked.
Fourth pass and I had issues finding 4th (that was a first for me and it was certainly a WTF moment):
At this point I was frustrated enough to consider leaving. It was just not happening. However, I put on the JLT. I figured I could do no worse, and maybe I would get my night redeemed.
After installing the JLT, and a total of 46 minutes after the last pass, I made my first JLT run. The run was clean. 60 foot was 1.8 and the pass netted a 12.18 @ 112.93:
As it was late, and I was beat and had my 14 year old with me...and an hour and a half drive ahead of us, I went back around and got in line...where I sat for probably 25 minutes. 32 minutes later, I made my last pass. It was clean and the pass net me a 12.043 @ 114.74. Here is the slip:

Ok, so this is where we sit. My best pass with the box is a 12.58 with a 112.98. That was a clean pass, with a weak 60 foot of 2.0. Corrected down it is 12.486 @ 113.84 a the DA was 827.
Best pass with the JLT was a 12.04 @ 114.74, corrected down it is 11.971 @ 115.384 with a 1.743 60 foot. This was my best pass ever, if you accepted corrected values.
The tune. I had 1 degree of global timing removed from both tunes (93 tune) because we had picked up some timing retard with the JLT on Tuesday. Shaun thought maybe it was hearing some knock, or there was "ghost knock". This did the trick as from what I have seen from the logs, commanded timing was followed and the knocks added enough to bring it back up to where it was supposed to be.
I sent Shaun the datalogs and he will be reviewing them today. I can take some screen shots if I can figure out how so people can see the runs.
One thing I noticed, I need a shift light. I was shifting past where I wanted to do. I did manage to pull 6400 and change on the big end, with my 3.31 and 26 inch tire combo. However, I do not think the 26 inch tire is optimum. I may try some tubes because apparently they will "stiffen" up the tires, and right now I have too much sway and had to run the pressures at 17 psi cold.
I said this in the other post, and I will say it here. I feel confident that the JLT made a difference. The car felt better, pulled harder out of the hole and just felt better throughout the pass. Shaun and I worked hard on the tune, and there was no issue with the tune not delivering. If anyone didn't deliver, it was me.
I will be out again and there will be a stage 2 of this test. The JLT is on my car, and will stay. I informed Jay that I will purchase the JLT as agreed. This was not a free part, and I have absolutely no vested interest in this part working.
Take it for what it is.
