MHD Flasher (G-Series / Supra)
What is this beast?
The absolute holy grail of modern tuning! Wagwan, you don't need to take your car to a shop anymore. You plug a Wi-Fi dongle into your OBD port, open the MHD app on your phone, and in 3 minutes your Gen2 B58 transforms from a tame daily driver into an absolute rocket ship. Flash a Stage 2 map, pour in some E40, crank up the exhaust burbles so loud it sounds like gunshots, and go terrorize the streets. MHD gives you the power of a professional tuning shop right in your pocket. Pure magic!
Why the stock part is absolute pain
MHD makes tuning your Gen2 incredibly simple. It completely rewrites the engine computer, turning up the boost, optimizing fuel and timing, and removing the speed limiters. The app also lets you monitor dozens of engine sensors in real-time, so you know exactly what your engine is doing when you are doing 150 mph down the highway. Just remember, if your car is 2021+, you'll need a FEMTO unlock first to let MHD do its magic. Once unlocked, it's game over for the competition.
