    Compact Design. The SF4/X4 Power Flash Tuner measures in at 2.7” wide X 5.5” tall making it much smaller than the original SF3/X3 for easy storage in your center console or glove box. The cord is detachable and there is no battery or power supply needed. It uses the power from your vehicle's diagnostic port or computers USB connection.

    Diagnostics. The SF4/X4 Power Flash Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own trouble codes rather than paying a dealer to do the same. Its as easy as a few simple steps.

    On Screen Data Logging and Monitoring. With a full color LCD display, the SCT SF4/X4 Power Flash Tuner makes it EASY to read the Built-In Data Logging or Real Time Monitored Vehicle Data, view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source.

    Easy to load; easy to restore. When you load a SCT pre-configured strategy tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done.

        What is the difference/benefit of the SCT tuner vs. the BAMA tuner? They look exactly the same...?

        • The SCT SF4/X4 Power Flash Tuner does not come with custom tunes whereas the Bama tuner comes with custom tunes and free tunes for life.

        Helpful (33)

        What's is the difference between the bama tuner x4 and the sct sf4? Do both have free tunes for life? I would like to know the difference before I purchase either one thanks

        • The tuners themselves are the same, but the BAMA x4 sf4 tuner is included with our free tunes for life program, whereas the SCT tuner of the same style does not come with free tunes for life.

        I recently purchased this the SCT SF4 tuner and during set up it "asks" if the car has a Steeda CAI. I am considering purchasing the Steeda CAI and I was wondering if tunes are already pre-installed on the tuner, or do I have to get custom tunes. Please let me know. Thanks!

        • With the SCT tuner, this will come with preloaded tunes that you can download onto your car for what mod you have. However, since you bought the tuners from us you will be automatically enrolled in Bama's free tunes for life if you wanted to get a custom tune as well! Sincerely,

        how many tunes can this device hold if any?

        • The SCT SF4/X4 Power Flash Tuner would be able to hold up to 10 tunes on the device.

        Helpful (7)

        Will this tuner get better use of any CAI kit? Assuming that it would program the computer to allow for more airflow in the intake.

        • Any aftermarket cold air intake will benefit and create more power with an new computer tune to the motor. Allowing the vehicle to pull more air will overall make additional power even if you cold air intake does not require a tune.

            Sct x4

            Very nice and works really great. Super easy install just make sure you update the device before installing there was about 470 files that needed to be updated FYI. Big difference shifts kinda hard but I’m going with a mpt custom tune to really get the full potential of my car.

            Be careful on racing tune

            This only happened to me once so far. I was on the freeway running the high octane racing tune, when the car decided to go markedly faster on it's own. (I wasn't pressing the accelerator.) I was up a good 30 mph faster than my cruising speed of 55 mph, when just like that it backed down to normal on it's own. This could be a problem if you don't keep your head and panic. Be careful it may happen to you. Other than that good product, and racing tune definitely can smoke some tires off a light.

            This ruined the computer in my car. I read the reviews and I didn’t see any other reviews saying something similar to this but I installed the the tuner step by step and it wouldn’t drive right (when I was accelerating the brakes were being applied and forcing me to slow down) after to the point where I had to replace the entire computer in my car. Very disappointed. Wish I never bought it it cost me time and money.

            An absolute disappointment

            When I first received this tuner roughly 2 years ago, I was thrilled to play around with it and adjust it to my preferences. It worked perfectly well for a while, but then I didn’t touch it for a year or so. Recently I attempted to use it again and there was a “program error” that showed up on the screen and allows me to access nothing on it. Considering this was roughly $400 and it is only a couple of years old, this was a complete waste of money and I am thoroughly disappointed with SCT. Also, it only has a one year warranty, which leads me to believe that this problem may be an intentional one by SCT.

            Preloaded tunes don’t work at all and AM fails to mention anywhere that tuners are NON REFUNDABLE until you actually try to refund it so it’s a waste of $400 you’re better off just going somewhere and getting a tune

            So I bought this and went with MPT 91 performance tune and it is night and day difference. The throttle response is so much better the trans turning shifts so much fast and cleaner, not to mention the overall power gains. If you are on the fence with this go ahead and buy it!

            This tuner has worked great for what I needed, switching tunes back and forth from e85 and 93 also the datalogging is what I needed for my tuner to adjust things on the fly for me. Easy to use easy to understand and navigate. Have been leaving it plugged in because the gauge display comes in handy.
