needed to installIt carries the connection between the app and your vehicle. One purchase — for all your vehicles, forever.
Safe by design, reversible by default
Tuning isn’t risky when it’s done right — the same calibration a good workshop would load, with the same safety margins.
- Your factory file, always on handWe keep a database of original OEM files, so your factory file is always there to restore — even if your ECU’s memory can’t be read.
- An interrupted flash is recoverableIf a write is interrupted, the ECU simply stays in programming mode, ready to resume. Once the flash completes, your vehicle starts normally — no permanent damage.
- One-tap return to stockRestore your factory file anytime — for a service, an MOT, or selling the vehicle.
- Within safe limitsYour tune is built by experienced engineers to stay inside your engine, turbo and clutch tolerances — never past what your hardware can take long-term.
Every map is calibrated by ActiveMotion, a professional tuning house that has tuned tens of thousands of vehicles. Available right in the app.
- 10+ yearsin engine software & calibration
- Every enginedeveloped on the dyno
- Custom-builtnever a generic file
- Reversibleback to stock anytime

Drivers like you, already on it
“Very satisfied. Despite a few errors during the update that I had to restart 2 or 3 times (without really knowing why), the promise is kept. No errors since, the on-board computer says everything is OK, and a real power gain you genuinely feel (+55 hp on my model). Super fast delivery, new map online in 36h (24–48h announced), nothing to complain about. I gave 4 stars because some options are quite expensive in my opinion, and you can't toggle options on or off without changing the rest — it's all or nothing. Something to think about for the future.”
“Received on time, ultra-responsive after-sales service… and it works like a charm!! I recommend!! Map requested for a BMW 428i — went from 245 hp to 280 hp and from 350 Nm to 430 Nm… wonderful, with the factory sport display adapted to match the new map.”
“Effective product, simple to use. Nothing to complain about.”
“Operation completed without a hitch in 9 minutes. Spectacular result. Spectacular acceleration for more safety. Bravo.”
“I did 2 E85 remaps on my two cars — an Audi A3 1.5 TSI and a BMW 218i. I have to say it's very simple to use and fast. Everything went well and I now enjoy both cars on ethanol. I recommend.”
“Hello — I remapped a BMW 525d F10, 204 hp, which went to 300 hp. Great result. There was an issue during the flash but Théo was very responsive — outside support hours at that — and it was sorted in a few minutes. Good product and a good team.”
“An easy, effective and fast remap. I'm very happy and don't regret my purchase.”
“Perfect, fast, good value for money, plenty of options and bonuses, and you can go back to stock whenever you need. Just a fairly long wait for my remap to be sent, but I recommend.”
“Friendly, responsive team — I recommend. Guidance throughout the install. Simple and effective!”
“Very good company with exemplary responsiveness! Thanks Théo for your precious advice, always attentive! I recommend 200%!!! Thanks again, team! 👍”
“The concept is a revolution. Reprogramming your car at will, from your smartphone, is a first. As a remap enthusiast I let myself be tempted without quite knowing where I was going, I'll admit. I ordered a map for my car and a few days later received the adapter, with which I flashed it. I plugged it in and after barely 15 minutes my car was remapped as if I'd been to a specialist. Customer service is ultra responsive — Chuck and Théo are there to answer when needed. The big plus? You can return the car to stock whenever you want, and remap it again at will. I don't have a sports car, just a simple Touran that needed a second youth. I've already done 1,000 km on the remap and everything is perfect. Thanks to the team.”
“Ordered a remap for my RS7 — Stage 1 and ethanol — impeccable. I'm delighted! Everything works well and above all it's disconcertingly easy to set up: 2 minutes and it's done. I strongly recommend their service, at prices that defy the competition… Thanks to the whole team. Laurent”
“I was looking for something discreet with the ability to quickly return to the original map. I chose Stage 1 with EGR deactivation. I was surprised by the gain in power and torque. The vehicle is a VW T5 4Motion, 140 hp stock. In 6th gear at 120–130 km/h I no longer need to downshift to overtake. Pure happiness.”
“Audi A8 D5 50 TDI. ECU remap… top and very easy. No worries.”
Questions, answered
Is it safe?
Is there any risk for my engine?
Manufacturers de-tune engines at the factory to cope with poor fuel quality in some parts of the world and to meet strict emissions rules — so there’s real performance left on the table.
Our maps are built by powertrain engineers to unlock that reserve while staying inside your engine, turbo and clutch tolerances: software optimisation, same hardware. And it reverses to stock anytime.
Can an interrupted flash brick my ECU?
No — an interrupted flash can’t brick your ECU. Flashing is all-or-nothing: if the write is cut short — a flat battery, a dropped Bluetooth link, the dongle pulled out — the ECU won’t run a half-written program. Instead it stays in programming mode (its bootloader), waiting for a complete file.
While it’s in that state the vehicle won’t start, which can look alarming but is completely safe: nothing is damaged and nothing is lost. You simply reconnect and re-run the flash — SmartFlash is engineered to recover from any state, finish writing, and the engine starts normally.
As a safety net, we also keep your factory file on hand, so you can always write the vehicle back to stock.
Will it void my manufacturer warranty — and is it detectable?
We’ve built the solution so that, once you flash back to stock, it’s usually not visible to a manufacturer — though OEM tools evolve, so we can’t promise that forever.
And to void a warranty on tuning grounds, a manufacturer has to actually prove the vehicle was tuned. A tune can still affect warranty cover, so it’s worth knowing your maker’s terms.
Will it affect my insurance?
It depends on your insurer and country, so we can’t give one global answer. Remember the tune is fully reversible to stock.
Is tuning legal?
It depends on your country and how you use the vehicle — laws differ across the markets we serve, so you’re responsible for checking your local rules. Either way, you can always flash back to stock.
Does it suit an older or high-mileage vehicle?
It can, as long as the engine is healthy and well-maintained — tuning rewards a vehicle in good condition, it won’t revive a tired one. Sort any wear or due service first.
Do I need a healthy battery to flash?
Yes. Flashing draws power for several minutes and the engine can’t be running during programming, so a healthy battery matters — and if yours isn’t in great shape, connect a charger. The app walks you through it; just don’t interrupt the process.
Flashing & the app
Can I switch between the tune and stock whenever I want?
Yes. Your original file is stored, so you can flash to stock and back to your tune in a few minutes from the app, as often as you like — handy for a service, an MOT, or selling the vehicle.
Is the tune really tailored to my vehicle?
Yes — never a generic file. Every map starts from a calibration developed on the dyno for your engine, by powertrain engineers.
You pick the stage and options, and it’s then adapted to your exact ECU software version.
How does this compare to a workshop remap?
It’s the same kind of calibration a good workshop would load — built by powertrain engineers — but without the day without your vehicle or the workshop price, and you install it yourself from your phone.
Unlike most workshop remaps, it’s fully reversible anytime.
How do you calculate the gains?
From dyno data for your engine family. Where we show a modelled curve, it’s labelled as such — what a healthy vehicle on the right fuel should make; your exact numbers depend on your vehicle’s condition, fuel and any hardware.
What does the gearbox tune do?
On automatic and dual-clutch boxes it sharpens and firms up the shifts, raises the torque limiter to hold the new power, quickens kickdown and launch, and removes factory shift restrictions.
It’s a separate optimization from the engine map.
Will more power increase my fuel consumption?
Not necessarily. Driven the same way — especially cruising — many customers see similar or even slightly better economy, because the engine works less for the same result.
Use the extra power often, though, and it’ll drink more, as you’d expect.
Does it work if my vehicle is already tuned or modified?
It depends on your ECU. Where we can fully read its current memory, we can back up an existing tune as a separate map you can keep and install whenever you like.
But our own tuning always starts from a clean factory base — we won’t graft options onto someone else’s map, since we can’t vouch for that work.
So if you have a Stage 1 from another tuner, we can save it for you — provided, as above, that the ECU’s memory can be read; but to get Stage 1 + Pops & Bangs as one of our maps, you’d take Stage 1 from us too (we can always build Pops & Bangs as its own map).
Stages, maps & options
Do higher stages need any hardware changes?
Some do. Stage 2 needs an exhaust change — on diesels the DPF must be physically removed, on petrols the catalytic converter (and the GPF if fitted). The configurator flags this when you pick Stage 2.
Stage 1 is software-only.
Can I add stages or options later?
Anytime. Add any stage or option later for its normal price — you won’t re-pay for the vehicle you’ve already set up — then a €49 build-or-update fee to roll it into a new map or update your current one.
I'm selling my vehicle — can the new owner keep my tunes?
Yes. We offer a transfer of your maps to the new owner's account, for the same vehicle (same VIN), for €99. Everything you had bought for that vehicle becomes available to them — they'll just need an OBD dongle to install it.
If you prefer, restore the vehicle to stock before the sale — free, a few minutes in the app. Either way, remember to tell the buyer if the vehicle is sold tuned.
Can I have more than one map for the same vehicle, and switch between them?
Yes. Everything you buy stays in your toolbox, and you can build several map variants from it — one with Pops & Bangs and one without, an everyday map and a full-power one.
There’s no on-the-fly switching in the app yet (it’s on the roadmap), so you switch by reflashing — a few minutes. Your first map is included; each extra is a €49 build.
The dongle & delivery
How soon do I get my tune file?
Once you’ve registered your vehicle in the app, most tunes are ready within hours — never more than one working day. You’ll be notified when your tune is ready to install.
When does the OBD dongle ship and arrive?
Dongles ship from our EU warehouse within one working day — same day if you order before midday — and arrive in 1 to 5 days depending on your country and whether you pick standard or express.
Exact delivery times show at checkout.
Where do you ship?
Anywhere in the EU.
Can one OBD dongle be used on several vehicles?
Yes. The dongle is just the plug-in interface between the app and your vehicle — it isn’t tied to one vehicle, so a single dongle works on any vehicle you own.
You buy it once; each vehicle has its own tune.
Guarantee
Do you offer a warranty?
Yes. We stand behind the calibration itself, and if your manufacturer later pushes a software update to your vehicle, we re-do your tune for free.
Every order also comes with our 30-day money-back guarantee, and the tune is always reversible.
How does the 30-day money-back work?
Within 30 days, flash your vehicle back to stock and send the dongle back to us in its original box and condition.
Once we’ve confirmed the vehicle is on its factory file and the dongle has arrived, we issue your refund.
