Default How do my logs look guys? Minor adjustments to XPT stage 2

Hey guys I had some problems with my recent flash to XPT stage 2 but I lowered the target boost tables and lengthened the wastegate arm by quite a bit. I think it's running much better now from what little I've come to understand in my learnings so far. I was just hoping some of you more experienced guys can take a look at a couple logs I ran today. I appreciate any feedback, this looking good?

Both third gear, had to let up at the end on both runs...caught up to traffic...

Wgdc is way too low at spool up, no wonder it isn't boosting quickly.

What should I do to correct? Change the max wastegate duty cycle tables?

Yes, with that setup you should make 16 psi before 3krpm. I don't know if the us cars are different, but I never touched my actuator to get that on the wrx's I've tuned.

Why did you lengthen the WG arm you should be tightening it. Could explain the poor spoolup if the WG is loose

Well the short answer to that would be I don't know what I'm doing and I'm a n00b. I will shorten the wastegate tomorrow and log again and see what the results are. My big thing was getting rid of the knock. I don't want to make things worse before I make them better.

There was no new knock events, only the learned knock. That means that the ecu pulled timing and fixed it on its own. Your iam is 16 so it seems like its happy. Pull a learning view and post it up. It shows the overall health of your engine better.

Just return the wastegate arm to what it was, post all of your wastegate tables and boost target tables.
