General ECU Reflash Information (Please read to get some basic understanding)


Stage 0 :  Very minimal power gains (from AFR trim. Boost stays as factory boost. Throttle response is improved)

Stage 1 : 30-45 whp 50-90lbs toque peak power gains from bone stock to basic bolt-ons (Intake/exhaust) on 2013+ Genesis Coupe 2.0T
** Results may vary (Dyno results was on the vehicle with intake only) **

Stage 1.5 : 40-60whp 70-125lbs torque peak power gains from bone stock to basic bolt ons 
** Results may vary per octane/car mods/etc **

- Better throttle response
- Usually gets better gas mileage (if you drive the same way)
- Less Rev hang
- Trims Air fuel ratio 
- Overall smooth powerband 
- Extra features 


!!!PLEASE READ and do your own research before purchasing!!!
Any questions other than what's stated, feel free to contact us through via CRM request page. 
We are more than happy to answer your questions. 

Basic features will come with stage 1 (that was in Stage 0.5 as well)

- Boost cut issues taken care of
Some vehicles (especially the ones with many bolt ons) were having issues with getting boost cuts due to exceed amount of turbo overspeed and torque management. We have fully covered and tested that there is 0 problems on boost cut issues that were seen in Stage 0.5
- Full boost Oil Temp is lowered
Sick and tired of waiting for oil temperature to hit 170F (75C) so you can get into full boost? We've lowered the operating full boost temperature to 135F (57C) where it's still safe but very reasonable amount of time to make sure everything is warmed up and ready to go condition

- 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.

- Retune

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.


- 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.

- Launch control (Optional $25. If you don't choose this option you will not get this feature)

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. 

- Mail-in or Pretuned ECU (+extra core)

THERE ARE only 2 options. Either you mail in your own factory ECU (or any other ECUs that we can use) or buy a pretuned ECU from us.

Pretuned ECU will come with either brand new or refurbished (Tested and checked) working ECU from us. It depends on the availability in stock but usually takes 1-3 weeks to your door. 

If you choose I will mail in my ECU, please ship your ECU to SFR USA 281 S. Whitford RD. UNIT 7 BACK SHOP, PA 19341
You MUST include prepaid return label from UPS or Fedex (for USPS, do it at your own risk.. no stamps allowed).

Turn-around time is UP TO what kind of shipping you'd use. We can flash it the same day and drop it off usually (Unless we are closed for certain occasion,
some mishaps with shipping company, etc). Please make sure to just send ECU unit (No bracket or TCU(For AT) attached). Also make sure to put your
order number somewhere on or in the box, at least some name that we can trace.
We also do not need a picture of your stock ECU as long as what you choose correct info in drop-down menu.

Due to how webstore is set up it's being advertised as "Free shipping" however you have to choose either $20 reg shipping or $50 express shipping (This shipping is from our location @ SFR USA) for PRETUNED ECUs ONLY. We apologize for the confusion here. 

This is one of the main factors we can produce more power safely. Don't ever run cheap low quality gas in your vehicle and expect it to perform.
Yes, Hyundai will tell you that you can run 87+ but that's with stock timing and boost map. As we are advancing those categories from the tune, you will have more gains from having higher octane YET less chance of detonation and such. 

Our best advice is always stick to well know brand gas stations and stick with highest octane as possible. You can still go up on octane for fueling (For instance you chose a tune for 89 octane and putting in 93 octane) but you CAN NEVER do it other way around.

As stated above, your vehicle must be in great shape prior to run more aggressive tune. One of the maintenance items you should change at least every 30k miles are the spark plugs. Since the tune will add more boost and advance more timing (thus will make more heat in each cylinders), we recommend running one or two step colder plugs. 
What works the best from our experience is NGK2309. Factory gap from NGK (0.030) has been working great but you can gap them down to 0.028 for less blow by.

- Warranty

ECU orders are custom orders per base so that all sales are final.
If you have to add or correct your order, please contact us ASAP. 
Anything that's our fault on the tune, we fix for you without a doubt.
Any changes we have to make for canned tunes, we will have to charge $100 for any retunes in the future. 

We don't guarantee anything about Hyundai's warranty with ECU flash. 
Get this service/product at your own risk just like any other aftermarket parts you put on.

However, it's not obivously seen or detected compared to any visible mods such as intake/exhaust/etc.

We always use original stock data pulled then modified to tuned data (if mailed in), so all the calibration data and other ECU functions remains exactly the same as stock

Or you can just switch your untouched stock ECU for dealership visits (if you order pretuned ECU).

- Feedbacks

We've been getting bunch of positive and "WOW" responses, but feedbacks are all over the places that can't get all of them at one place.
We've been collecting some of feedbacks that we can find and it's here:
(Please read through the initial thoughts and impression that fellow Genesis owners have experienced) 


Any questions please do not hesitate contact us.

PLEASE MAKE SURE NOT TO mail in any ECUs during this time. We will not be responsible for any loss/delay. Sorry for the inconvenience it may have caused and thanks for your understanding! *******

Stage 1.5 - Night and Day
I will start by saying this tune is a total improvement over stock, especially for a canned tune. The power throughout the mid-range to top-end is much more noticeable. I ran a data log with DashCommand during my test drive and had no problems with AFRs, and I hit a higher peak boost of course. (On stock spark plugs, car is stock except for a K&N Typhoon Intake). Also, upon starting the car after swapping ECU's I had no check engine lights, and no issues what so ever - except for the burning rubber smell coming from the wheels after getting sideways around a couple corners. I ordered VIN coding and my Bluelink works, which is awesome. I received my tune two days after it was shipped, which is awesome since considering SFR had put it in a priority mailer to get it here faster. This, in my opinion, was a huge bonus especially since the shipping was free. Jay has been in Korea but SFR/Jay still answered my questions via email . Overall, I am very satisfied with the service they provided despite the hectic timing of my order during Jay's trip. To the prospective buyer: This tune will totally change the performance of your car for the better. I highly recommend it. To SFR: Thank you for this product!

Like a New Car
I just paid off my '13 Genny and the Stage 1.5 flash is my first mod. After 50,000 miles of driving it bone stock, I immediately noticed the difference in throttle response and reduced engine warm-up time to get full boost. My OBD app shows a 30% increase in peak boost, from 16.8 psi to 21.9 psi. Shipping was fast, the outer packaging was slightly torn as the silly mail person tried to fit the ECU into my mailbox instead of leaving it at the door, but there was bubble packaging on the inside and the ECU was not damaged (would prefer SFR to ship UPS or FedEx instead USPS). Swapping out the ECU is simple, only tool need was a ratchet with a 10mm socket. I was so excited that I forgot to let the new ECU calibrate the wastegate position feedback before starting the car and ended up in limp mode with a CEL code P2562. I realized immediately what had happened, so I pulled the ECU fuse to reset it and did the "key dance" procedure. It has been running smoothly ever since. Since this is my only mod I chose not to go with the NGK spark plugs yet, but will probably buy a set once I add a new intake. My only regret is not buying this sooner.

I could not believe how easy it is to install and do the key switch magic. After that pandoras box was opened! This isn't the same car. These guys are a step ahead in everything. Even with a bad flash on the first try, it was worth the couple of days wait on the new ECU to show up. Now I only lack H2O/Meth, injectors, and turbo upgrades. I plan on solely using SFR for that!
