Default Visconti Tuning - 2015 WRX STI - Tuned With EcuTek RaceRom !

Event: Dyno Tune !
Location: MR Performance| Westbury, NY
Ambient Temp: 65 degrees
Elevation: sea level
Weather: Very nice out

Car: 2015 STi
Tuner: Visconti
Dyno Info: Mustang AWD-150
Peak HP at RPM: 293WHP @ 5400
Peak Torque at RPM: 325WTQ @ 4200
Baseline hp/tq for a stock on same dyno: 279WHP / 255TRQ (Peak)
Target Boost: Intelligent - Wastegate / Sport 17PSI / Sport Sharp 20PSI
Target AFR: 11.0
Fuel: 93 unleaded
Engine/Power Modifications: Visconti STG1 EcuTek Tune



If you haven't driven one of these yet don't unless you plan on buying one, this car is pure awesome! I absolutely love the built-in boost gauge and the steering wheel makes me drool. The tach takes a bit to get use to..and IMO it's a shame it still has the old EJ motor in it but Subaru did such a nice job on everything else I'm willing to forgive them

Tuning wise everything is pretty much the same, factory tune is aggressive and held in closed loop until higher RPMS. This particular car during the baseline was running 23degrees of timing in the upper RPMS - yikes! So just like previous years anyone with one of these cars would benefit from a STG1 tune to prevent cracked pistons / rings.

Customer plans on coming back sometime next week to get a downpipe installed, will post the results once it's back on the dyno.

Car was tuned using EcuTek RaceRom, and has both on-the-fly adjustable Launch Control with boost off-the-fly and Flat Foot Shifting

Remember when a turbo swap was required to get 300WHP? This thing did 293 out of the box on Pump gas as a "stage 1" tune with no exhaust! They sure have come a long ways.

Anyways, results speak for themselves nice smooth curves, no mountains.

Ecutek is silently doing some really cool stuff.

Any small updates to this engine over the previous ej257?

if you aren't willing to immediately get a tune, what is a safe way to break in this car so that the rings wont be an issue?

impressive numbers you guys.

The car is a lot of fun. Picked up a good amount of midrange power, and is super smooth. You need this if you have a 2015 STI. It is noticibly quicker with just the flash.

The adjustable 2 step launch control is great. Adjusts launch rpm with the cruise control button on the steering wheel. Very trick. Flat foot shifting is a nice feature too.

This car with a lot of power should be awesome. Can't wait to mod more!!

If it had an FA20 in it i would have bought one, shame, subaru. Shame.


Also, those numbers seem a little high to me...|



Does anyone know if these EJ's have the same pistons in them as the previous generation 257?

Yeah, they have some really trick stuff

I'm not aware of any changes, car ecu a few extra maps now, but nothing major

impressive numbers you guys.
If your on 93 octane it's not so bad, just avoid handing out at redline under full boost.

The 91 octane cars I've done were pulling 5 6 degree of timing stock, just amazes me

Not everyone breaks in the motors the same.. I personally let the motor see a range of rpms off boost and do a good amount of engine braking.

I knew you'd like the Launch Control

If that other 2015 doesn't come in by tomorrow then all that exhaust stuff is up for grabs

Yeah, I did the baseline several times, almost didn't believe it.

But it only makes 279 right at redline and it's due to the amount of ignition timing it's running.

On the stock cars I normally see 20 degrees fading to about 18 in the upper RPMs, this car ramped the ignition timing to 23 at redline.

So nothing crazy, just a strong car

Wow these new 2015 models look really promising and im loving the interiors. Coming from an 07 to this model would take some getting used to "looks" wise for me. Im just not feeling the exterior but i could talk myself into it suppose. lol

Guys, let me tell you that the new car is light years ahead. It's absolutely phenomenal in every way. It's really much more nimble and tight. The interior is fantastic, steering wheel is superb, and seats are incredible. The feel is astonishing once you get the Ecutek tune. It just feels like there so much left on the table that the Ecutek tune unleashes. And I can see with my own eyes where the stock map timing is in the logs...not great for our horrible Canadian fuel.

Anyone in the Vancouver area want to check out my car, please hit me up. You have to see how amazing the car feels with the Visconti tune!

Thanks John for the clarifications. Then this is why Subaru ramped up and state "the best STI ever produced."

Ways to go Subaru.

I saw M2.35 beat Lexus IsF from 0-60 and even 1/4. Yet the 15 STI beats e M2.35.

Please keep us all updated

so the variable launch control rpms is a tuning function not a factory option?

in order to get these functions one would need a ecutek cable, and a laptop to send the data to the ECU via the obdII port?

Yes, the on-the-fly adjustable launch control is part of EcuTek's custom code called RaceRom, same thing with the flat foot shifting.

You would need a EcuTek ProECU Kit which contains a EcuTek cable and key to run the software on your computer.. you can only flash ecutek with Ecutek hardware
