MFS Connect

Petrol power.
Flashed from your phone.

Mobile ECU tuning for VW Group petrol engines. Plug in the adapter, flash from your phone, reverse it any time.

One email when it goes live. Nothing else, ever.
Built for the VW Group

The whole flash, from the driver's seat.

MFS Connect pairs with the MFS OBD adapter over your phone. Read the ECU, flash a tune, log a drive or pull fault codes, without a laptop, a cable to a garage bench, or an appointment.

Every flash is reversible - the original manufacturer software goes back on whenever you want.

For tuning companies

Put your tunes in front of owners you'd never reach.

MFS Connect is a distribution channel for tuning companies. Your files sit in the app next to ours and the owner flashes them themselves. No cables to post, no remote sessions, no time zones to work around.

Encryption happens on your machine, before anything is uploaded. We hold the file and never the key, so we cannot read your tunes, and neither can anyone who gets hold of them.

01 VIN-locked. Every tune is locked to one vehicle. It cannot be copied to another car, another owner or another account.
02 Delivered in-app. Any supported car, any country. The owner buys, downloads and flashes without you being in the room.
03 Your prices, your name. You stay the tuner. We handle the adapter, the flash and the support around it.

Request dealer access

We're taking on dealers before launch. Tell us who you are and which platforms you tune, and we'll come back to you directly.

We read every one of these ourselves.
