Some aftermarket intakes don't exactly have a fixed filter location, and this can cause MAF calibration issues, so you could try to adjust it a bit to see if it makes you run a little leaner.
Thanks for taking a look. From what I've read the Cobb OTS Tunes are usually on the rich side. How do they compare with the stock WRX tune from the factory?

The car feels ridiculously fast. I'd appreciate if some of the regulars on here would take a look at the log and let me know their thoughts. Thanks, guys.

Damn that looks like it is a blast to drive! I saw that Ron just picked up a 2015 WRX to play with. I think good things are on the horizon. Now I just need a E85 station closer to my house. My body is ready.

It’s so much faster than my 93 octane tune. I couldn’t believe the difference that 5 gallons of e85 makes. When I first got tuned by Ron on 93 we were battling high rev knock from the get go. He eventually got it cleared up, but this time around with the e85 in the tank, there was no knock and each revision just got faster and faster until the final one in the log I posted above. The thing rips.

Eric, you mind taking a look at my track log?

If you want to get rid of it you either need to use higher octane fuel, or you need to get an Accessport and maybe a custom tune either through a protuner or with the Accesstuner software. If this DAM reduction is only recent, it's probably just due to a bad tank of fuel.

In my experience, these engines are pretty knock-prone at 1.0-1.3g/rev on the stock tune. You'd be in this load range a lot cruising up hills. Lower gears and higher revs while climbing hills may result in less knock and DAM reduction. DAM reduction reduces timing more at high loads than at low loads, so you're likely very safe in terms of high load knock (the damaging kind). The learning is happening at low-moderate loads, and your engine is then protected from knock at high loads because of the reduced DAM. The downside of this is that you sacrifice quite a bit of power with a lower DAM. Buy an Accessport. You won't regret it. Even with an OTS map, you should get less knock than stock.

Edit: It seems you've used 92 from two different stations. Does it have 10% ethanol? These engines run better with some ethanol. Do you have access to even higher octane? A DAM as low as 0.18 on 92 octane is pretty odd. If you put some race gas in and still have a lot of DAM reduction, you might be looking at a bad knock sensor, though it's pretty unlikely.
Thanks for taking a look and your response. It makes alot of sense, and is very helpful! I was out last week, so I haven't done alot of testing, but after seeing your post, I started monitoring load alot more, and alot of my driving to and from work is cruising at around 1.0g/rev, and that is typically when I am seeing my DAM drop. I kept my revs higher and it didn't drop as bad. I am thinking that nothing is wrong, and it is a combination of the hills I drive every day, how I am driving them, and the problems you mentioned with knock on the stock tune in that range.

The 2 stations I used, both have 10% ethanol, and 92 is the best I have access to. I am thinking of altering my driving on those hills (higher revs) and see how things improve. I am also looking into getting an Access Port, and will hopefully have one in the not too distant future! Your post really helped me out, and makes me feel much better about what I am seeing. Thanks again!

Wasn't liking how the car was running on the cobb intake. Seemed a choppy when in boost at WOT. Ended up putting the stock intake back on.

Logs were created with the default markers set on the AP. I don't believe it includes command fueling.

I am posting on behalf of a friend. Can you guys look at this log. He got a e-tune done by a well known tuner in Canada and after one map rev the tuner is calling this as final.

Why is target boost so low? Am I missing something?

Probably because it's really cold and intake temp compensations are reducing the boost target.

We asked why he set the boost so low and his answer was to keep it conservative for winter and that he will revisit the tune in the summer.... Is this always the case? Dose everyone in Canada run a winter low boost map and a summer high boost map?

Only people whose tuner doesn't understand how to properly use temperature compensations.

One revision and the tuner calls it final. That should speak for itself. Looks like he gave you the most conservative tune possible because he didn't want to take the time to do the job properly.

Tell your buddy to find someone who gives a **** and have his car properly tuned.

I mean the car feels good and it pulls hard. But even with the target boost set low, you guys have any comments on the log/tune?

We weren't sure if these big name american tuners like PhatBotti and BrenTuning tune us Canadian vehicles, with our poor quality fuel and our large temperature swings from +40c to -40c.

Get a bren tune if you can.

It is possible to have a car finished in very few revisions.
And the tuner may be “dumbing down” the explanation on cold weather boost for the general consumer so I wouldn’t say any of this is wrong.

Also look at the creep he’s getting. That means the tuner is being super conservative here in the cold. That may be what he means

Bren has tuned my 2015, I live in Quebec. I had absolutely no problem with tune in winter. I have just traded for a 2019... I have a hard time waiting to tune again... so much difference in drivability.

New Botti etune following Perrin header addition. e60 for tuning. Will drop back down for daily.

The first log looks like a big boost spike at 24PSI,

also these logs look like you're running pretty lean.


I'm thinking I may have a boost/vacuum leak. Any one know what target boost is on MAPerformance tunes? I'm seeing 15 PSI regularly. I'll probably get a log later today to look deeper into it. I'm thinking I may have a boost/vacuum leak.

Yeah...boost control needs to be fine tuned.
It's intentionally targeting 12.4-12.3 on E58 mix... it's a little lean but fairly safe for the amount of ethanol.

Hey would someone mind checking out my log, make sure everything looks healthy. Plan on going full stage 2, but want to make sure it's rock solid before I put anymore mods on it.

2016 WRX - MT
- Stock minus AP, muffler deletes, and drop in filter
- On 93 pump gas, using COBB's 91 stage 1 tune

3rd/4th gear pull attached https://drive.google.com/open?id=1df...F4czJNCAtXfbEN
