Looking to Tune your 2015 or 2016 Audi S3?
Tuning your Audi S3 is most often one of the first mods you would do to your vehicle. This is generally the first modification because software tunes are by far the biggest bang for you buck when it comes to getting more power out of your 8V S3 model. With the Uniconnect+ cable you have the ability to flash your Audi S3 in the comfort of your garage. No need to pay labor fees to have someone flash your vehicle, and have the ability to flash the car back to stock before you take it to the dealer for service.
This Uniconnect+ Cable will allow you to install a Tune on your Audi S3 at home.
Just Add the Tune you Want to your Order
Once your order has been placed we will need the VIN number of the vehicle you will be flashing so we can allocate the tune to your vehicle. Once you receive the cable you can load the Unitronic software onto your vehicle.

What do I need to flash my Audi S3?
The only items required would be the Uniconnect+ Cable, a laptop that meets the minimum requirements (found HERE), and a battery charger to keep the battery voltage above the minimum requirements during flashing.
Why Unitronic Over the other Tuners?
If you are looking to flash your S3 on your own there are a limited number of options you have. Of those options Unitronic is the most established and reliable brands. This means they do a ton of testing and tuning to ensure your vehicle not only makes great power, but its driveable too. You will also have the support you need to take care of any trouble you might encounter during this process. The last thing you need is to go with a tuner who you cant even get on the phone.
Why Flash My Own Car?
Flashing your own vehicle means you don’t have to drive long distances, sit around in waiting areas or pay labor for someone to flash your vehicle. This doesnt even take into account all the additional features you get from the Uniconnect+ cable.
What else can the Uniconnect+ Cable Do?
The cable has a ton of great features. Aside from being able to install your Audi S3 tune, you can also Data log to help you track down issues, scan and erase ECU faults, Flash your vehicle back to stock, and adjust advanced settings including no lift shifting* and launch control* (* Not yet available on this model).
Do you need an internet connection to Tune with the Uniconnect+?
Yes, a stable Internet Connection is required, as a connection to Unitronic’s servers is necessary to use UniConnect+. UniConnect+ is not just “map switching”. UniConnect+ empowers end users with the freedom to actually reflash their ECU memory.
Does Unitronic offer a Audi S3 E85 Tune?
Not at this time. E85 requires additional fueling which exceeds the ability of the factory fuel system. E85 Tunes also requires calibration adjustments based on actual Ethanol content from fill-up to fill-up which makes E85 tunes very tricky.
Am I limited to which tune I can install on my car?
No you are not. You can purchase and install Stage 1 (for 91 octane), Stage 1+ (93 octane), and Stage 2 (w/ downpipe)
Will the dealer know that I have a tune?
If anyone at the dealer test drives a tuned MK7 R or S3 , they will certainly know that it has performance software. In regards to the dealer being able to detect the tune it is unclear at this time. There is a flagging system called TD1 which will make a note if it detects if a vehicle has been tuned. As far as we know the flash counter is not used to determine if it has been tuned at this time.
Will they know if I flash it back to stock?
At this time we are not aware of any Untronic flashed vehicle that was put back to stock, which was TD1 flagged when it went in for service.
