Hey all, I have a catted Invidia turboback exhaust and Cobb SF intake on my 2012 WRX. I'm running the Cobb OTS Stage 2 + SF (93oct) NWG Map using the AP.

I simply request that those of you with tuning expertise would please look at this 3rd gear WOT datalog and tell me if things are looking normal.

My future plans are to get a 3 port EBCS, PLX DM-6 SM-AFR Wideband, and Torqued Performance Stage 2 tune. Until then, I just want to make sure my car likes the Cobb tune.

Thanks in advance for any input.

I can post up more logs if necessary, but this was the only one I was able to get while out on lunch today.

FYI There aren't many tuners on this board that will work for free. I tune my own car but would not trust myself to tune others.

That being said, you're making a healthy 263whp @ 5210 and 288wtq @ 3777 . Your tune is getting a bunch of "acceptable" knocking, in that its hearing knock but then pulling it right back out. You need to hook up a WB and log your AFRs to verify how safe the tune is.

I didn't realize I was asking for free tuning, lol.

I have just been used to going on cobbtuning.com to the forum and posting up a log, then [email protected] responds with some vague comment about how everything looks pretty good other than a little knock, then suggests a couple of ways to troubleshoot it. Now that the cobb forum is no longer active among Cobb employees, they said they would be on the other subaru forums regularly to help with this stuff still...

I guess I just didn't realize looking at a datalog and telling me if it looks like my engine's gonna blow up or not was asking a tuner to "work for free." My apologies.

I suppose I will just hope nothing blows up until I can get a protune.

Thanks.

Your log looks fine. Your A/F learning is a tad on the higher side of what you would like to see on a GR but it isn't alarming. You have a tiny bit of FKL which isn't a bad thing, but keep an eye on it. If the values get higher or more frequent than they are you may want to consider running the 91 map with your 93 fuel.

Kept an eye on FKL on my drive into work today. Didn't have any for the entire drive and I got on it a few times. It has been super humid in the mid nineties here for the past few weeks, so I thought maybe the heat was causing some of the knock. It was mid 60's on the drive into work today.

Thanks for the help!
