Would recommend this for an m57 engine. Using this on my x5 with no issues so far. ### 5/5 — 2011 335D *2026-02-13* Simply lovely, I was looking around at the few tune options I had to choose from and bit the bullet choosing DFlasher simply because of the good power and because it is an app which makes everyones lives easier. Flashing is super easy but MAKE SURE your battery has over 12v before you flash. I made the mistake of flashing with 11.5v connected to a tender and it bricked my ecu. Luckily they have a flash back to stock option and a ecu recovery option so all I had to do was charge the battery above 12v, flash back to stock and it relocked my ecu and un-bricked if thats what you want to call it. 10/10 developers and would definitely recommend this to others with a M57! ### 5/5 — M57👍 *2025-10-22* The MHD of Diesel 🙏 ## Frequently asked questions about DFlasher ### What is DFlasher used for?
