MG Flasher

Plain and simple, this is the best interface for the gen 1 B58. I looked at MHD and Bootmod3 and this one was the easiest to use for me. Their customer service is great as well.

I mostly switched over to this platform for the antilag options but I began to love it even more because they allow you to play with so many more perimeters than the other platforms allow for. Definitely love it so far

Amazing platform

Having tested MHD and BM3, by recollecting data from logs, dyno and dragy times, I can tell that by far MG flasher has the best OTS maps available for the B58 engine. The time gains in high altitude environments (8600ft) and low altitude envs is remarkable, without putting the engine components under maximum stress (from the data I’ve read on the logs testing the multiple maps they offer) which make them very reliable maps. I’ve been running stage 2 for 1 year in a 2018 M240i with 0 issues. Also the app is very well crafted and easy to use. The flash itself is very smooth, and it has great features such as map switching on the fly which is great feature for those out there using pump gas for the regular commute and E30 on the weekends. Their support is great and they always listen an reply to your questions in a timely fashion. I just have positive words for MG flasher and no complains, keep the great work guys.

Love how easy it is to use and great tunes

This product is awesome. The extra power for my B58 is kick-in-the-pants noticeable. I’ve sent them a question twice now and both times responded quickly and helpfully. Highly recommend.

I’ve been using MG Flasher since I believe March 2019, I’ve put roughly 20k miles on my 2018 340i XDrive since release and it’s awesome. I started with the android app and switched to iOS when it was released. It’s cloud based now so you aren’t locked into a specific system anymore. I flashed initially with cable but now use the Thor wifi adapter. The car feels great, beast at times when I push it, it’s the ultimate sleeper and daily driver. I also flashed with the recommended xHP transmission flash, running stage 3. I drove the mg flasher stage 1 for roughly 2/3 of the miles and the last 1/3 with stage 2 since I installed the Precision CG-1 downpipe and BMS intake. I’ve had zero issues, absolutely none. This is my first BMW and now I’m spoiled. I’ve read about how people have to remove the ecu to unlock and mail away for the G20 and for other brands. This is so easy it’s ridiculous. I haven’t dyno tuned, but the car must be in the 480-500HP at the crank range now. I’m looking forward to stage 3 once it’s released.

Been using these guys for about a year, anytime I have ever had a question they were quick to get back to me and help me. These guys special in a couple bmw models and IMO are masters at their craft!
