Stg "2+" 300hp/360trq

Default Not braggin, just sharing: 2010 WRX, Stage 2+, vf52, IAG/Jorge Tuned 300hp/360trq

Long Story short, I blew my headgasket, and had IAG rebuild the motor a bit stronger for future additions. Old setup was COBB OTS stage 2 with spearco TMIC, COBB DP, and K&N drop in filter. never dyno'd. but ran fine from 84,000mi til I discovered the headgasket issue @103,000mi.

just finished the protune by Jorge last weekend and thought I would share.

sorry for the big pic, but i wanted to show everything with sufficient resolution for those that would want to see it. going into the tuning session, Jorge warned me that i would be taxing the stock fuel pump pretty hard, and likely to failure at some point. and he sure wasnt kidding. after getting a bunch of runs in, he showed me the pump strugging to maintain fuel pressure, especially at high RPMs and it was causing misfires. so, he tuned a few other cars while IAG threw in the new pump and he finished up my tune last.

here is the dyno plot. the run conditions are listed for comparison. these runs were made approx 6hrs apart. the ONLY change between the runs (besides ambient conditions) was swapping the stock fuel pump out for a Walbro255, and then some touching up. note, 29 runs on the stock pump to hash out 95% of the tune, then only 3 more runs to touch it up.

ive added on graphs of Fuel pressure, AFR, and Boost. final tune is bolded (obvious)

:shrug: ask Jorge. I trust his judgement. 12:1 isnt THAT lean considering i see most people around 11.8.

heres a plot with SAE correction, not sure what you guys prefer to see.

No need to get ya panties twisted,was just a simple ?

Could be because u didn't care to save the motor long term so run it lean as much as possible or play it safe and run lil rich. Either way was just a question

As for preference... who cares, won't change your tune so it doesn't matter what others wanna see.

?? no ones panties are twisted bud. it was an honest reply. you asked why so lean, i replied that i dont know, and Jorge must have decided it was fine. theres plenty of injector and fuel pump to do so if he wanted to.

Interesting graphs. Let us know how the car feels in winter when those 12.0s turn into 12.5 when it gets cold.

Was the afr reading from the downpipe or tailpipe? That'd explain alot.

I have a PLX M300 wired up, but haven't had a chance to put the sensor in the downpipe yet.

Does it? either way give a pen to a new born baby and they draw a line more linear then that afr.

so hitting mid to low 10-1 afr well before peak trq/psi then leans out at peak trq/psi and continues the to lean out up top...

I paid for a tune like that once. Im actually glad I did as I then learned the right way... My car was a friday last car of the day tune aswell.

OP im not trying to rip on you ive been there years ago...

Folks that have a clue run that lean on E85... PumpGas and your asking for trouble, no less. Maybe on a inline motor but on a boxer. I think not.

1. my take, at least on the low 10:1 and then back up and down, is that you are seeing tip-in response and then a slight overshoot as the AFRs stabilize.

2. this car has forged pistons and an equal length header. slightly lean (higher temps) isnt nearly as bad as with a UEL header and stock cast pistons.

3. Im spitballing here, but maybe ignition timing (which i dont have on hand) would be something else to consider. from what ive seen, Jorge typically tunes conservitavely, and maybe the safety concern of a leaner AFR can be offset by more conservative ignition timing? feel free to correct me if i'm wrong, just thinking out loud.

4. this is a daily driver car. very rarely will it go over 6k rpms anyway.

just my impression based on what ive read in the past, and how i drive the car. feel free to comment/disagree/whatever, but everything is a learning experience.

at the end of the day, everyone knows that Jorge is a top notch tuner, and that IAG is a top notch shop. i have faith in their abilities and experience, and their integrity to stand behind their work if something were to happen as a result of anything they did or did not do.

Yeah thats what jorge told me back in the day... A learning experience it is... tip in and all. now both my personal subarus run double the size injectors i had back when that tune was performed. My afr tip in looks nothing like that. Sometimes proper maf scaling and various injector adjustments take longer then some are willing to spend time on.

Im sure hes running less timing do to the afr but a boxer is inefficient and needs timing and fuel. Just what ive been taught at work. I was in the same and thought that was good and not excuses too. Then my eyes where opened... At one point I deff had alot to learn. my setup could have been more properly built. But overall Im glad. Learned what not to do... But I had no idea of the fail, till I was working with tuners that actually know what to do.

IAG does some neat fab work though.

Im glad your happy with your results. as long as your happy as your the one driving the car and paying the bill.

I believe he tunes for P&L in NJ.

But as an update to people worried about the AFRs, here is a few videos I took today. I installed a PLX M300 WBO2 unit and sensor.

Sensor is in the Cobb downpipe here:



Videos.


2nd gear pulls (not enough road close by for a safe 3rd gear) last vid is a slo-mo vid, half me wanting to capture the updates, and half me just playing with the feature on my phone lol

AFRs seem pretty consistent to me all the way to redline. Dips to high 10's on spool up and then settles around 11.5ish to redline.

I have no explanation why the dyno graph says otherwise. Maybe the car is learning to add more fuel on its own via the O2 sensors? The car isn't running in open loop mode or anything like that.

Either way it runs great. 2700miles on the motor so far. So far so good.
