AT One
Many customers want to tune their vehicle at home, on their schedule, and often your workshop is simply too far away. But with the AT One, your workshop is in their pocket.
It's the ideal tool for maintaining contact with your customer and enabling them to flash your tune from their home. With the AT One and its mobile application, your customer can easily read his vehicle's data, send you the engine calibration file and contact you within the interface with questions or concerns.
Bringing OBD protocols from the Tool to the One
Protocol selection is fully automatic. No guesswork. No risks. Just results your customers expect.
We are working hard to bring all the OBD protocols from the Tool to the One, but this process takes time. While this is our goal, we are initially targeting the main manufacturers, ensuring the best coverage and functionality for the most commonly used vehicles. Stay tuned for updates!
At AutoTuner, we like things quick and easy
Discover more benefits
Customers want to tune their car when they want and where they want. Now they can.
With the AT One's MyFlasher mobile app, everything is at their fingertips: read/write, file transfer, data logging, code scanning, live chat, all in one place.
It’s like having your entire workshop in their pocket. And that means you now have a global reach, and a larger club of loyal customers, all without adding staff or opening new locations.
No subscriptions. No huge buy-in. No master tool. No closed ecosystem. Just a 10-pack of Ones and you’re officially in business.
We’re passionate about the tuning industry as we were tuners ourselves. The AT One lets you focus on creating awesome tunes and providing excellent customer service, not worrying about your balance sheet. It’s simply the AutoTuner way.
Here’s how it works: You can buy a little as 10 AT Ones at a time. The per unit cost is extremely low so you don’t have your cashflow tied up in inventory on the shelf. Then when you sell it to a customer, you then pay for the activation. That’s it. You set your own pricing. We don’t nickel and dime you.
Our top friends in the industry are using the AT One to distribute their own tunes and linking up with other tuners and expert file services to meet their customer needs on other vehicle brands. What you do is totally up to you and your shop’s needs.
And here’s the best part: We handled the hard stuff nobody wants to touch: the hardware, the read/write protocols, the cloud backend, the mobile app, the updates, the support… all so you can focus on tuning and making customers happy.
Are your tools falling behind? They probably are.
Tuning the latest vehicles gets harder every year, but not with the AT One.
It’s built on AutoTuner’s cutting-edge OBD protocol catalog. And since the One is designed for your customers, protocol selection is fully automatic. No guesswork. No wrong selections. Just results.
And the AT One device? No wires. No mess. No laptop. Just a smartphone and you customer is tuning.
That’s not the future. It's now.

For the end customer
The MyFlasher mobile app can be customized with your logo and brand color, delivering a seamless experience for your end customers.



Talk with your customer right through the app. No need to call, text, email, or hunt down prior conversations. The vehicle details, files, trouble codes, data logs, and chat logs are all right there in one convenient location.
We make it simple. When a customer reads their vehicle, the files automatically send to the AT Cloud interface. No hunting down files or remembering if you chose the right one.
While each One device is linked to a single vehicle via its VIN, the app allows you to manage multiple One devices, enabling support for multiple vehicles.
For you, as a tuner
The AT Cloud management interface is your dedicated dashboard for managing your AutoTuner tools.
A tailored offer for your business
As a tuner, you first purchase the hardware, then activate the software when selling to your end customer. This allows you to start with a low investment and quickly optimize profitability.

No. You set the price. There’s no minimum advertised price, or MAP, and we don’t sell them to end consumers, just businesses like you. Bundle it with your tune and deliver incredible value to your customers.
You only pay for the One pack and the Software License when you sell it to your customer and activate the device. That’s it.
There’s no dealer buy in. No setup fees. No subscription or maintenance fees. You don’t need to own the AutoTuner master or slave tools. Nothing for the cloud service or mobile app. Not even anything extra for the branding!
The total price is the same for every vehicle. We don’t charge more for something exotic. There’s no limitation on the number of files or times you can read/write, and there’s no extra fee for flashing multiple controllers such as Engine and Transmission.
Maybe we should have just answered “No.”
No restrictions: you can send as many calibration files as you like, at no extra charge.
Here is the link to the AT One compatibility list.
It's in our DNA: the number of vehicles supported by the AT One is constantly growing... So don't hesitate to keep up to date by subscribing to our newsletter!
The One is a single tool for one vehicle. The AT One has been designed so that the end customer can reprogram his vehicle, not so that he in turn becomes a car reprogramming professional. The AT One is linked to the chosen vehicle by VIN number. However, you can exchange as many engine calibration files as you like with your customer, at no extra cost.
Yes. They’ll need to be connected to the internet, either with Cellular or Wifi to download the file from the cloud.
We have rigorously tested the One in a wide range of situations. Unfortunately, it's never impossible for your customer to encounter a problem related to battery voltage or incorrect actions during writing... Thanks to the AT Cloud management interface, you can consult all operations carried out by your customer and help them if they encounter the slightest problem. And, of course, our support team is always close, should you encounter any problems.
No you don't.
No. You’re not locked in, either by investment, or proprietary
file types.
The AT One supports a binary file format, so you're free to use whatever editing software you want and deliver the tunes however you want.
You do whatever is best for your business and your customers, which surely means using the One of course!
We sell them in packs of as little as 10 devices.
