First datalogs after engine rebuild. Thoughts?
I know, everyone is probably sick of these "i'm new to teh datalogz, plz halp" but any input would be appreciated. I'm beginning to understand what i should be looking at and what it all means.
Cobb stage 1 93 octane
Use shell/bp 93 octane gas
1200mi since new shortblock, valves, etc
85degF, ~50% humidity
First Log (my commute from work to the highway):
Second Log (highway cruise):
Third Log (3rd gear pull):
I'm comfortable with the first two logs, but the third log has me slightly concerned. The DAM is at 1 which i'm pleased with and the maf seems to be reading consistently, boost is hitting target and tapering off, the knock feedback is pretty low and occurs right about throttle lift-off time, but the knock learning is what concerns me.
I plan to get a pro-tune in a few months when i get all the requisite stage 2 items, but wondering if i should invest in one before then.

I'm new to datalogs as well, just started learning about them today and what all the stuff means. I think it looks pretty good, just that your ecu remembers where it encountered knock and pulled timing, twice in a few places. I'd be concerned about that too. Maybe you can try to reset the ECU to see if you get feedback knock and it learns the same values again?
From what I've seen on the romraider forums, you don't need the accel position, just throttle position. AFR would be interesting to see, however I think it would be ok since AF Learning is pretty neutral IIRC.
