BMW 5 Series and M5 tuning
The N54 and N55 535i, the B58 540i, and the S63 M5 in F10 and F90 form — custom MHD tunes, on our hub dyno or remotely.
Priced per car on a call · in our Corona shop or remote anywhere in the US
The 5 Series is supported where it shares engines with the rest of the range: the 535i’s N54 and N55, the G30 540i’s B58, and the M5’s S63 twin-turbo V8 in both the F10 and the F90.
The 535i and 540i are the most common six-cylinder 5 Series to tune; the M5 is the S63 V8 at its most serious, and the F90 sends it through xDrive.
On our dyno in Corona
Bolted to a Mainline ProHub hub dyno — no tires, no straps — and calibrated against measured power, with the conditions on the sheet. Our hub dyno runs rear-wheel-drive cars. xDrive (all-wheel-drive) BMWs are tuned remotely on MHD, from your logs.
Remote, anywhere in the US
- In MHD, screenshot the DME’s bin number, software version and readiness page, and save the stock .bin file MHD reads from the car.
- Send them to us with what is fitted and the fuel you run. We write the calibration for that car.
- Flash it with MHD. You log, we read the logs and revise until it is right.
What we tune
Models, engines and unlocks
Every car here runs an engine MHD supports. What changes from car to car is what has to happen before the first flash.
| Model | Chassis | Years (US) | Engine | Before the first flash |
|---|---|---|---|---|
| 535i | E60 | 2008–2010 | N54 | Flashes over the OBD port |
| 535i | F10 / F07 GT | 2011–2016 | N55 | May need a bench unlock, depending on software |
| 540i | G30 | 2017–2023 | B58 | May need a bench unlock, depending on softwareCars built after 06/2020 need a special unlock |
| M5 | F10 | 2013–2016 | S63 | Check with MHD’s Unlock Check |
| M5 / Competition / CSxDrive | F90 | 2018–2024 | S63 | May need a bench unlock, depending on softwareCars built after 06/2020 need a special unlock |
Unlock requirements are MHD’s, and they follow when the DME was built, not the model year. MHD’s app has a free Unlock Check that tells you exactly what your car needs.
Before you buy
Questions people ask
- Can you tune an F90 M5?
- Yes. The S63 in the F90 is on MHD. It is all-wheel drive, so it is tuned remotely from logs rather than on our dyno, and a car built after 06/2020 needs a FEMTO or AutoTuner unlock first.
- How much does a 5 Series tune cost?
- It is quoted on a call while we finish publishing BMW prices. The figure depends on the engine, what is fitted, the fuel, how many maps you want, and whether the DME needs an unlock first. Call or send the quote form and you get one number before anything is booked.
- Do I need an MHD licence for a custom 5 Series tune?
- Yes. MHD licences are bought per car and held on your MHD account, and a custom tune needs at least the MHD Flasher licence — the map packs are optional. You also need MHD’s wireless adapter. If you do not have either yet, tell us on the call.
- Will a tuned 5 Series pass a California smog check?
- No. Since July 2020 California Smog Check reads the engine software’s calibration ID, and software that is neither BMW’s nor covered by a CARB Executive Order fails. A custom tune is for off-road and competition use, and we will say so before you buy, not after.

A tuned BMW will not pass a California smog check, and adding power costs longevity and economy. We say so before you buy. Emissions disclaimer
