What is Remote Tuning?
x2.jpg)
Since 2013 we have tuned VW, Audi and Porsche remotely, for owners who never set foot in our shop.
No dyno appointment, no dropping the car off for a week, no shipping a computer across the country and hoping. You flash your own car, in your own driveway, with us on the other end reading what it actually does.
Since 2013Over a decade of remote tuning, on cars from MK3 to MQB.
Logs and revisionsIncluded at no extra cost. We tune from your data, not a template.
No PC accessWe never remote-control or touch your computer. Ever.
The cable is yours$40 once. Keep it and reuse it on every future tune.
Works worldwideAnywhere with an internet connection. We ship the cable globally.
What is remote tuning?
Remote tuning means we calibrate your ECU without the car ever coming to us. You plug a cable into the OBD port, our software reads what is on the car, and we write a calibration for that exact engine code and hardware. You flash it yourself, then send us logs so we can check the result and revise it.
It is not a download. A download is a stranger guessing what your car looks like. Remote tuning is a conversation with the data your car produces, and on a twenty-year-old engine that difference is the whole thing.
How it works
01
Order
Choose your tune in the store. A GTS cable ships with your order for a one-time $40, and it is yours to keep.
02
Connect
Plug the cable into your OBD port and a Windows laptop. Our software identifies your ECU and collects what we need.
03
Flash
We build the calibration for your engine code, your hardware and your fuel, and you flash it yourself. You get a message the moment it is ready.
04
Log and revise
You drive, you log, we read it. If anything wants adjusting we adjust it and you flash again. Revisions usually come back the same day, and within 72 hours at the outside. If it is going to take longer than that we tell you.
Datalogging and revisions are included
This is the part worth understanding before you buy anything from anyone. A calibration written blind is a guess. Logs from your car, on your fuel, in your weather, with your hardware and its actual health, are the only way to know it is right. We want your logs, we read them, and we revise. That is included in the price, not sold back to you afterwards.
It matters most on the cars we tune the most. A twenty-year-old 1.8T with a tired in-tank pump, a leaking vacuum line or a lazy N75 will show all of it in the data long before you can feel it. A shop that does not want your logs cannot tell the difference between a tune that is wrong and a car that is worn out, so it will blame the car.
If a tuner will not look at your logs, that is the tell. There are seven more in how to spot a fake tune.

What you need
- A Windows laptop, Windows 10 or later. An Intel Mac running Boot Camp works too. Apple dropped Boot Camp on the Apple Silicon machines, so an M-series Mac needs a Windows laptop alongside it.
- A stable internet connection. A mobile hotspot is usually fine, and plenty of people do this in the driveway.
- The GTS cable, $40 one time, shipped with your order and reusable on every tune you buy from us afterwards.
- An Android app is in development, which will take the laptop out of this list entirely. Ask where it has got to if that would change things for you.
- A healthy battery, or a charger on the car. A flash is a bad moment to run out of volts.
The software is ours
Every part of the flashing chain is written in house. The tool that reads your ECU, the protocols it speaks, the client you run on the laptop: we build and maintain all of it. Nothing here is a rebadged third-party package with our name on the splash screen.
That is not a boast, it is the reason the rest of this page is possible. When a car has an ECU variant nobody else supports, or a checksum that has not been published, we can go and solve it instead of waiting for a vendor to. It is also why support is a conversation with the people who wrote the software rather than a ticket queue.
Your security
We never ask for remote access to your computer. No screen sharing, no remote-control software, nobody clicking around on your machine. Our tool talks to the ECU and to us, and that is all it does. You stay in control of the process from start to finish.
Your original calibration is read and kept before anything is written, so the car can go back to stock whenever you want it to.
Where we work
Worldwide. The cable ships at a flat $11 wherever you are, and remote tuning itself has no border: it only needs the car, the cable and an internet connection. We have tuned cars in Australia, Germany, the United Kingdom, the Netherlands, New Zealand, Hungary, Puerto Rico, Panama, Costa Rica and Barbados alongside the usual US and Canadian work.
Prefer to mail the ECU in instead? Mail-in service is free within Canada and the USA, and we flash it on the bench and send it back.
Hablamos español. Remote sessions, email and support in English or Spanish, whichever you would rather use.

Use the car selector to find the tune for your exact engine code, or tell us what you have and we will point you at it.

Ordering from Canada
GTS has tuned VW, Audi, and Porsche for Canadian owners since 2014, and Canada is our second-largest market. Remote tuning works the same as anywhere: the tune is delivered digitally, and the flashing cable is delivered within Canada, with no customs and no import fees. We accept Canadian cards. Prefer to ship the ECU? Return shipping within Canada is free.
