MHD N55 E-Series

Everything from minor diagnostics to tuning and editing capabilities are in matched. I’m able to upload even custom tunes from my tuner if I’d like through MHD App. Their OTS tunes have had my car pushing that little extra power but still underrated to bmws OE parts so I’m not constantly worrying about my engines health.

I’ve had a terrible experience with this company. Purchased orange mhd adapter and mhd monitor license. Could not log at all. It only showed READY and no option to log until they released app update. Then the adapter keeps disconnecting randomly. Mhd blamed phone Bluetooth, and it still disconnects with bt disabled. Mhd is a liar. Asked for refund and received a rude response.

I've had this for almost two years and it does everything within the app, diagnosing, reseting adaptation, logging, guages, and all tuning options you could ask for. I HOPE to see an anti-lag option soon though, YES we want an anti-lag option! Thank you for developing an app so easy to use!

Honestly can’t really tell a difference between stage 1 and stock. Running latest map. Stage 1 seems like no power added on a 135is

They need to add Vargas Stage 2 and Pure Stage 2 Turbo upgrade maps ASAP. The N55 E-Series cars are way too left out, underworked and left behind. So much stuff that N54‘s and F-Series N55‘s get to choose from we don’t have.

Car is responsive, insane power , great customer service 5 stars deserved!!!!

great platform, very easy UI to navigate and amazing customer service

Tuning made easy

This tune is way better than my old piggy back tune. Had an issue with my data logging and their support system responded right away.

This is an absolute treat. I love what this has done for my E92 N55 it’s like a new car to me. I’m still looking for more goodies to improve my car. I purchase the super license and it was well worth the money. Suggestion: can you include signal pass thru so that the iPhone can still function while using MHD? Thanks for your consideration
