BMW ECU Remapping

BMWs are among the most requested cars in our workshop, and for good reason. A bespoke calibration brings out the performance the engineers built in: stronger, smoother and more responsive across the rev range.

  • Original software kept on file
  • Licensed WinOLS
Overview

Why remap your BMW?

BMW engines are engineered with considerable headroom, and the factory calibration leaves a lot of it unused. A bespoke remap refines boost, fuelling and ignition timing for your specific engine, giving more power and torque, sharper throttle response and often better economy on a steady cruise.

We inspect and log every car before we tune it, then write a calibration for that vehicle. On models with an automatic gearbox we can also tune the TCU, so shift speed and torque limits match the engine.

Engines

BMW diesel and petrol tuning.

Diesel

BMW diesel tuning

BMW’s turbo-diesels respond exceptionally well to calibration. Expect a much broader spread of torque, stronger in-gear acceleration and effortless overtaking, often with improved economy.

Petrol

BMW petrol tuning

From four-cylinder 20i and 30i engines to the six-cylinder M340i, M40i and M cars, a petrol calibration sharpens response and lifts power throughout the rev range.

Great experience with tuning my 4.4 TDV8 L322. The car feels much more responsive and seems to be more economical. Given the extra power I may be driving like a hooligan, so will be difficult to confirm. Callum knows his onions and I would highly recommend.

I had my Audi A1 remapped by Callum recently and the difference is amazing. Better acceleration, more torque and now averaging almost 60mpg on a long run, 45–50mpg around town. Throttle and turbo response so much better.

Had my car remapped and could not be happier. Callum was so friendly and really helpful. Had a few issues with the car running hot but managed to sort it and wouldn’t leave the car until he was fully happy with it.

FAQs

BMW remapping: your questions answered.

How much does it cost to remap a BMW?

Pricing depends on the model, engine and any other work you require. Send us your vehicle details or registration and we will come back with an exact price.

How long does a BMW remap take?

Most remaps take 2–3 hours including pre-checks. We will confirm timings when you book.

Can the remap be reversed?

Yes. Your original ECU software is saved before any change, so the car can be returned to standard at any time.

Will a remap affect my warranty or insurance?

A remap may affect a manufacturer warranty, and you should inform your insurer of any modification. We are happy to talk through the implications before you book.

Can you tune the BMW automatic gearbox?

Yes. We offer BMW TCU tuning for faster shifts and raised torque limits. See our gearbox tuning page for details.
