Excellent tuning app and outstanding customer support
I contacted MHD with a few technical questions about Stage 2 and Stage 2+ on my S55 engine. Their team responded quickly, clearly, and honestly. They didn’t try to sell me unnecessary upgrades—instead, they explained exactly what made sense for my setup and fuel quality.
It’s rare to find this level of transparency and technical knowledge. The app works great, the tuning is reliable, and the support is first-class.
Highly recommended!

For b58 better off getting mg flasher
Comparing the mhd b58 stage 2.5map 95oct with the mg flasher b58 stage 2.5map 95oct, the mg flasher has better throttle response , faster turbo spool , cleaner logs with no timing corrections.

Update Issues
The recent update has created two error codes for CAN 1 and CAN 2 sensor timeout. The Ethanol sensor value is at 0%. Following a reflash the car generated a Power Management Fault and Incorrect Shutdown Error. The Ethanol sensor value went to 0 again. No issues with car or software since last release. Why do updates get pushed automatically? I’d rather update after everyone exposes bugs and they are resolved. Clearly MHD tests code in production.
