This is my first datalog with my xpt stage 2 map. As far as I can tell everything looks good to me. What does everyone else think??

looks pretty good. As I recall xpt maps call for 8* knock correction, yours drops to 7 in a few cells up top. It's probably a correction made to the fine learning correction table thats pulling a degree of timing. I think your boost target is more like 17.5 too, but contact braden he should be able to answer all your questions.

Boost target is in 4th gear, I did a pull in 3rd gear and according to the instructions should be a target of 16.

Get rid of A/F sensor, total timing, intake temp, knock correction, and wastegate duty cycle
Replace them with feedback knock correction, fine learning knock correction, IAM, and boost error

Is the boost oscillating a bit between 3454rpms and 4604 rpms? It's very slight but it seems to jump up and down a bit.

I only ask because I'm having the same problem. Or maybe it isn't a problem?

OP, was there any audible wastegate flutter during this pull? That might explain the boost fluctuations... but I'm just guessing here. And I generally only hear it at part-throttle so I'm not even very confident in this guess.

Pft-pft-pft-pft, like 2-3 times per second. It's louder on some cars than others.

I've never heard anything like that so I'm gonna say I'm not getting any flutter.

Hey all,

I'm new to subies/NASIOC and dont mean to threadjack, but I may be getting a wrx soon that needs a tune and was thinking of going open-source. Are there any FAQ's/tutorials etc that would be good to read first? Also any personal success/failure stories w/opensource tunes? Thanks!!

logs look good, take the suicidal eggrolls advice on logging parameters though and don't forget to use learning view before and after a logging session!

i run a xpt stage 2 map as well and its a little conservative but a nice solid platform!

be safe!
