STEEDA Tunes for Life User Guide

Dear Steeda Customer,

Thank you for your recent purchase. You will soon receive your files for your SCT tuning device. Please follow the steps outlined in the “What to Do” section to avoid any issues when loading custom tunes.

Some important things to note

Do not install any hardware that requires a tune prior to receiving the tune from Steeda. For example a “tune required” cold air intake or other tune required hardware like a 2018 intake manifold or VMP loom. Your car will not be able to run properly until the tune is installed
Steeda will not change or alter any emission control devices on your vehicle.
Premium fuel tunes will use 91 to 93 octane, US Ratings (equivalent to 97 or 99 UK octane).
We only tune for premium fuel on boosted applications.

For NA (Naturally aspirated) Applications we can provide non premium fuel tunes on request, however performance will of course be less than with premium fuel.

The Typical turnaround for most custom tunes is 3-5 business days except for Gen 3 Coyotes which are 7-10 business days after Steeda Tuning receives your tuning form. This can take longer if our tuning department are very busy, OR if your ECU Strategy code is a “new” one it may require unlocking which can create quite a long delay. However this is usually only the case in very new cars where new strategy codes are still being revealed and unlocked.

What to do

While waiting for the programmer to arrive, go to sctflash.com and download the “Device updater utility”. https://az824306.vo.msecnd.net/software/SCTDeviceUpdater.exe
Install the device updater onto your laptop/pc
Once you receive the SCT handset, take it out of the package and plug it into your computer. Open the “Device Updater” that was installed in the previous step and click “Automatically check for updates”. Let that run its course. NOTE This can take a long time to complete, even a few hours!
Go to the vehicle and read “Vehicle Info”. You will need to write down the strategy and SWPN.
Complete the tuning form on the Steeda website .
Go to https://www.steeda.com/tuning
When you fill in the form put STEEDA UK or STEEDA EU as the sales representative + your order number
MAKE SURE you fully and accurately describe the hardware on your car. Not all Intakes are the same, so if you put down the wrong intake for example it may mean your tune will not run well on your car.
When you receive the email with the tune file, save the file to the computer.
Now that you have your tune ready, you need to “Automatically check for updates” again.
Now is when you click “Load custom tune file to device”, find your file on your computer and add it to the SCT device.
You can now go to the vehicle and load the custom tune to the vehicle. Make sure you use the file in the “Custom” section, not the “Preloaded” section. For the Bullitts, we usually include the Kxxxx number in the file name and description as long as you included it in your order form.
Be Patient! The upload MUST NOT BE INTERRUPTED.
Enjoy your new tune!
Keep your SCT X4 somewhere safe.
