Hey guys, decide to data log my car on the way home from school today.
2002 Z06: K&N Filter, Borla cat back, and a diablosport canned tune (93).

Don't know much about tuning, and have the file on my other computer so i will try my best to explain everything through text. Did 1 WOT pull from about 30-70, then did a WOT pull in 6th from 70-85. Along with some regular driving.

Long term fuel trim bank 1: %
Min: -0.7813
Max: 9.375

Long term fuel trim bank 2: %
Min: -2.344
Max: 9.375

Short term fuel trim bank 1: %
Min:-16.41
Max: 25.78

Short term fuel trim bank 2: %
Min: -19.53
Max: 17.97

Spark advance: (deg)
Min: 3.000
Max: 39.50

Intake air temp (deg F)
Min: 96.80 (cruising on highway) about 99 degrees here in Texas
Max: 123.8 (Sitting at a red light)

MAF sensor air flow: This one i don't understand that well (g/s)
Min: 1.420
Max: 294.8

Knock Retard (deg)
Min: 0

Just trying to get a better understanding on what all this means, and if it's good for the engine. Any help is appreciated, and if you need any more information, i'll help where i can.

Thanks ya'll,
Logan

It would be better to actually view the log file.
Diablo gives min/max of the entire log. It's good for things like knock retard, but not so hot for other parameters.
Also, with no wideband, hard to say how the engine is actually tuned.
