Went to the track today. My previous best is in my sig and that was at 55* weather. The only thing I changed was the 90mm and increase my timing by 4* Temp was 100 plus degrees in the hot muggy Texas weather. I ran a 13.5 at 99.xx mile per hour. Maybe back home in Oct. when it is in the 40's or 50's maybe I can it 13.00 or 12.99

There was this girl at the track. She had to be the most gorgeous girl that I have ever seen. Small, skinny blond. She was racing a motorcycle and ran a
8.5 1/4 at 151 MPH
I am in LOVE
My A/F was running about 11.5 to one but when I hit third gear it drops down to 10.5 to one. I don't know what to do about that, anybody have any thoughts on that.
Thanks
Mark

Look at your maf hertz and air speed when all is good. You see that you enter a different air speed/hertz when you go rich. Mine is backwards, I am (was)lean in the 1/2 area and normal in the third gear. You could just think you are rich in the higher area. What are you commanding when you are at 10.5? If your commanded afr is off you just need to rinse and repeat the maf quiet a few times. You'll never be able to get it on, but real close.

I have a couple of threads out in cyberspace about why so lean in 1/2 and normal in 2 through 3. Seems to be the maf.

I have seen that also. Heat soak can be the cause alot of the time. As long as you are not showing lean in the higher gears it is a good thing.

sinces I started this post here in FI I will not move over to the tranny section.
Today my tuner tweaked my tune a little and I went out to take it for a test drive and launched the tranny. I have no foward or reverse gears. I neither felt nor heard anything. I was on the top of second gear and all of a sudden I bounced off the rev limiter. Thought maybe it missed the shift for some reason. So I slowed down and pushed on the throttle and nothing. Came to a complete stop and tried all gears and nothing. It was 7:00 pm on a Sat evening and I am 1700 miles from home in Arlington Texas. I had bought my tranny from Rock-On transmissions. I knew he was somewhere in Texas. So I thought I would give him a call and leave a message on his voice mail. But Dave picked up. Come to find out he is about 60 min. from where I am. So I had AAA tow my truck back to the Hotel and He said he will have his tow company pick up my truck from the Hotel on Sunday and start working on it Monday morning. He was very nice about it and said he will take care of me. Great customer service.
I will keep you guys posted.
