Basic feel of reflash2.0T SFR ECU Reflash F.A.Q
*Video of dyno results from SFR canned tuned on 2.0T with AEM intercoler kit+piping+downpipe+axleback exhaust
~35rhwp ~70lbs/ft gains on Mustang MD Dyno with load!
* 4th gear results (45rhwp 100lb tq on 5th gear)- What are the modifications do we need to do?
You MUST take care of the vehicle (Just regular maintenance from oil change to scheduled Hyundai recommended items such as Spark plugs, coilpacks ,etc) make sure the vehicle is problem free and has no mechanical problems.
Canned tune is off the shelf tune that works from anything bone stock to full bolt ons. Also means you can add canned tune at anytime and start adding other bolt on modifications (intake, exhaust,etc). There is no such thing as bolt on tunes (Don't be fooled by some competitor's tactics making their tune looks superior) when there is no way of matching all the combinations of different bolt-ons you might have.
Every car also has slight variances from factory the get-go and where you live to how you drive/take care of your car can vary results. Being said, we've seen the results over and over that canned tune works for all cars. Sure it may not be perfect but that's when you want the custom tune on the dyno ( It can be only done in person @ SFR USA or any tuning events we might have). Also means you WILL NOT BE ABLE TO run our canned tunes for stock turbo/wastegate/solenoid, injectors, etc on your bigger turbo,bigger injector, etc application. Those applications will need either different canned tunes or custom tunes.
If you are only putting in some bolt on parts such as intake/exhaust/etc, you don't really need the retune. Flahsed ECU will act just like stock ECU that will relearn itself overtime. It only takes few seconds to reset the ECU by pulling the ECU fuse in the fuse box located near the battery. You will not loose the flash by disconnecting the battery or pulling the fuse out. ECU flash is permanent. ECU will go back to when we first flashed the ECU after the reset. If you are coming with other tuner's tune, we will have to charge extra to returning ECU back to stock first to get the basedata made. So far we are the only vendor that reuses the ORIGINAL stock data converted to tuned data.
- Custom Tune
We are very proud of the FACT that we are the only company who offers In-HOUSE tuning solutions using In-HOUSE tuner for popular Hyundai/Kia vehicles.
Don't be fooled by some remote tuners who pretends to be working on your vehicle or just middle-man who bringing tuners from overseas.
Our in-house tuner's been working on these vehicles from the day 1 who will have solutions and answers for you (No language translation issues, some half made answers come from the middle man).
Though you can still get great gains from canned tune, it's still a tune that is meant to be used for any cars with different mods/environment. In order to maximize and squeeze most out of current set up, custom tune is recommended. It can be only done on the dyno in-person that you'd need to visit SFR USA or come to one of our tour locations (if there is custom tunes are offered). We can also custom tune bigger turbo/injectors/etc that we've been doing.
* Please note we have rights to refuse to tune the vehicles that are equipped with anything that we think it's dangerous or will give problems on the dyno.
Please contact and provide us pictures of the set up and list of parts on the car prior to the tune session so we can give some suggestions.
We've already done Tomei/Evo X/Evo 8/9 kit/19T turbo/GT35R/Precision 6262 turbo, BK2 OEM injectors/ 500cc/ 550cc/750cc/1000cc injectors, etc.

- VIN CODING (Pretuned ECU only Extra $25)
IF you are mailing in your own ECU, you DO NOT have to choose this option.
We can code your VIN number on pretuned ECU so there is no "VIN not matching" Check engine light and also it's easy to get inspected and such without inconvenience of switching the ECUs. IF YOU DO NOT CHOOSE THIS OPTION, we will code with just RANDOM VIN that contains "SFR" at the end.
Those who are running BLUELINK remote start system (BK2 2.0T AT only), you MUST have matching VIN to use that feature.
- 2 Step
You can only apply this to Manual transmission for launch control.
THERE IS NO SUCH THING AS LAUNCH CONTROL FOR AUTOMATIC TRANSMISSION!
If you have AT model and you still want to have it, we can add it. However it won't be used for launching the vehicle.
(You can use to show off and such..... as it's been requested many times)
* It's an ignition cut limiter while building the boost (about 5-7psi) that will bounce off at 4K.
We offer Brake boosting feature (BK 2.0T AT only) for Auto transmission instead.
If you select Launch control option, you WILL LOOSE CRUISE CONTROL feature from factory.
- KOREAN POPCORN (Crackle and pop )
Adds aggressive crackle and pop during deceleration letting off the gas pedal around 2-4k RPM at light throttle.
Has no gains as far as the performance goes. Sound will be depended on your exhaust set up.
