First time at the track this year and my car only trap at 101 three times and 97 another. I data logged the car the next day with free scan and my o2 were reading .80-.98 the whole time. I registerd knock around 4800 rpms at times knock went up to 8.3.

Last year i traped at 105.75. And since then i added ram air.
I also have nittos now but my 60 foot times are still bad (2.2-2.4) Like last year.

I think i could have let off early on the 97 mph run but my et was the same.

Where can i go to learn more about the readings i got from the free scan? I am going to buy lt1 edit, but would like to know what i am doing first.

Thanks
Kevin
