Overall a very good tune though, good hp/tq given the basic bolt on mods.

You should provide an explanation with your post so the rest of us can learn. It's difficult to take anything from such a vague statement.

hater, do you have a laptop? download enginuity and go for a ride with Jay and have him monitor things while you do a few WOT pulls... he can see any possible knock that way and see if the ecu is pulling timing. and also see if there is boost fluctuation. just a suggestion man.

Travis,

The car was logged on the dyno and on the road when it was tuned yesterday. I think the only knock correction was a -1 somewhere in the powerband on 1 pull and the tolerance for timing pull was set to somewhere around 6. I highly doubt that anyone, in any world, on any dyno, would let a car leave if it were knocking and causing that much of an influx in power throughout the duration of a pull. As far as the boost goes the stock turbo (go Mitsu!) just doesn't seem to be able to keep up. Just means its times for a bigger (go Mitsu!) turbo.

so the car will be driven in a place where there is more oxygen and then run leaner? (lower elevation)

Then have a magical AFR shift after it gets of the dyno?

AFR, IMO, is a meaningless number without other parameters....timing, just to name one. If he's monitoring a -1 KC somewhere....it's probably enough knock to eventually, break a ringland.

Oil consumption FTW!

I believe he was tuned to around 15ish psi. But the poster or tuner would have to reply. I was just an innocent bystandard who was observing and having a good time.

Poster. Please post your "after" tune compared to the "stock". 07's are horrendously different than any other years for Subaru from what I understand. I just think we could all get a better grasp on what's going on with a before and after.

And back yet again...talking to the poster...I think he posted a "mid-day" tune and not the final tune. He should be posting the final tune shortly. Silly poster.

Heres a graph of the final pull. Much better AFR's. The dotted line is the stock (untuned) graph. Sorry bout that first graph! Feel free to rip the stock AFR apart haha.

There's the sheet I thought I was commenting on. Well done in getting the right plot posted. Congrats again on the results.

really hard to read the #'s but im assuming thats closer to an 11.6:1 afr... and yes i agree that the stock tune was garbage in comparison to the final product.

Hey guys,
heres a bit of a run down of the tune...

The oscilation in the curves are the horrid boost control waggling around, dealing with way hot temps in the shop and some heat soak near the end of the day. We saw a torque peak of about 315 ftlbs right where the point in the second plot is, but that was backed off for a bit smoother onset of boost.

The KC map is smoothed to 6, throughout the day there was no timing being pulled from knock, there was one pull with way to hot IAT's that pulled a bit, but nothing that i would ever expect to see in the real world with real world air flow, this was due to some severe heat soak.

The first plot was a midway pull to try out some changes on the throttle duty maps, there is obviously some experimentation to be done with increasing duty to 100%, definately throws the fuel maps well out of calibration. so the duty cycle maps were set back to stock and mildy tweaked.

I could not get boost to hold up top, theres potential for much more whp if boost doesnt taper off so badly.....18g anyone??? i know its waiting...
MYIX8UR8 and Slowturbo's days both being awfully hot. sucks trying to combat heat soak etc, but at least you know the air can only get cooler.

the afr's are also set to 11.6 ish, im not a fan of 12's at all, makes power but it also makes way to much heat. the extra fuel gets used for thermal management, I prefer to set afrs on the rich end of whatever range the car is happy with for that exact reason, too rich and it breaks up, just a touch leaner and its happy and cool.

the 07 wrx turbo feels and tunes like the 1.8t's, good low end spool, not a whole lot of air up top, but makes for good useful torque where its fun to drive.

Thanks again for coming up guys, its always fun and amusing

cheers
