Cobb AP data log - knock retard?
I tried running Cobb stage 1 map and has knock retard values in one of the runs as follow:
4000rpm 2.11
4700rpm 3.16
5300rpm 2.46
6500rpm 0.70
Occasionally i get values of 0.35 appearing in 1500rpm to 3000rpm range.
What do these numbers mean? Does it mean i was knocking? The strange thing is that it only appeared in one of the few runs which I data logged. Im running 94 octane, what gives?

Those are so minimal you should only worry if you see anything higher then 3.00-4.00. 1.00-2.00is normal even on the stock tune w/ or w/o bolt ons.<-- to cplise
To OP dont run stage 1 unless your stock. Otherwise it wont like you.

Well am i knocking or is it just preventing knock? also anyone know if ABS. pressure is boost. i have gotten 31-36 psi ( other have asked me the same question)!
( legend goes SEC. RPM, ECT, TPS, ign advance, LTFT, KNOCK RETARD ( 7th column ) , WGDC fine, maf, abs. Pressure , load boost / fuel, load timing. SEE SNIP
Thanks

so should i worry about this i have seen as high as 1.05? i took 3 more logs today. i guess i should see if its getting worse. do you think i could of gotten some bad gas or is the cobb map bogus?
