Mercedes-Benz ECU tune

ECU tune for your Mercedes-Benz, calibrated for your engine and flashed on our 4WD dyno in Brossard, QC, or remotely with AZM Flash, our remote tuning device, shipped to your door. Cars that can't be tuned remotely don't need the trip either: ship us the ECU, and Tommy and our team tune it at our shop and send it back within 7 to 10 days. Your stock file is saved, so the car can go back to stock any time. Pick your model and stage on the AZ Tuning page.

Ask about remote tuning

For certain vehicles and tuning setups, our specialists may request datalogs to monitor performance, verify everything is running properly, and fine-tune your calibration when needed. Vehicle compatibility and ECU unlocking requirements may vary.

Straight answers

Are the gains guaranteed?

No. The numbers on each page are our estimates for a healthy stock engine. Fuel quality, weather and the car's condition move them. That's why we put cars on the dyno before and after.

Will a tune affect my warranty?

It can. Dealers treat software changes differently. If your car is still under factory warranty, call us before you book and we'll tell you honestly what we see.

Do I need to drive to Montreal?

No. Most cars can be tuned remotely with AZM Flash, our remote tuning device, anywhere we can ship it. For cars that can't (a locked ECU, for example), you ship us the ECU: Tommy and our team tune it at our shop and send it back within 7 to 10 days. Each car's page says which applies.

What does Stage 2 need?

Each car's page lists the exact requirement, usually downpipes. Catless downpipes are for off-road use only. We make our own and can quote the package with the tune.

Do you tune transmissions?

Yes, and on Stage 2 and up we recommend it. The factory TCU keeps the stock torque limits and shift points, so part of what the ECU tune adds gets clipped. Where we have a fixed price it's on the car's page; otherwise Tommy quotes it with the ECU tune.

My car isn't listed.

The catalogue has the cars we have a fixed price for. We tune more than that. Message Tommy on WhatsApp or call with the year and engine, and he'll tell you if we can do it.

How does buying work?

Pick your car and stage, add it to your cart and check out on our store. Right after your order, we text you a link to book your appointment with Tommy. He then calls you to confirm the fitment (ECU and hardware) and walks you through the next step.

Questions before you buy?

Fitment, mods, warranty, a car that isn't listed: ask Tommy. He answers himself, usually the same day.

Open Tuesday to Saturday, 8 am to 6 pm.
