MHD Flasher For 2020+ A90 Supra Discussion

[Shelby Miles]

Just completed the MHD+ update using Multi-Map and enabled Flex-Fuel. All works as advertised so far. I also enabled anti-lag.
When the weather clears, I'll go put some corn in her and let her rip.

Hats off to MHD. Everything is working flawlessly so far. I added 5 gallons of corn and got 35%, next time will be 6 gallons to get closer to E50.
The car rips. I need to get a draggy and do some pulls. Next, @Twisted Tuning for a custom flex fuel tune. No doubt this car loves ethanol.

correct, Through MHD+ menu

I’m loving everything so far except for the BC button cycling through the dash displays on my M340i when I’m navigating the MHD+ menus. Is masking the button’s original function when the menu is active something they can do to prevent this? It’s quite annoying.

Are you saying you still want the button to work for cruise functions when the MHD+ menus are active?

No. On the M340i (Not sure how it works on the Supra), the BC button on the turn signal stalk still cycles between the different BMW info displays on the dash (As it does normally) whilst in the MHD+ menu. I was wondering if it’s possible for them to disable the original function of the BC button while the MHD+ menu is active to prevent this so that the only thing changing is the stuff related to MHD+.

I get it. The Supra isn't like that.

I heard on a video that you can change the engine startup sounds, also curious to hear sound clips of the exhaust valve options. Are these anywhere!?

Bugger, had hoped my car being one or the early models (Sept 2019) a DME unlock wouldn't be required

Has anyone tried the new MHD DIY unlock feature? Any feedback as a home DIY?

Are you talking about the exhaust flap?

By that ROM ID you had the dealer update does. So that requires a bench unlock before you can flash.

The at home unlocker works. You just need to buy the hardware from www.bimecu.com

And then the mhd license.

Or you can use our mail in service for unlock. For $175+shipping

All pre june 2020 need bench unlock if you had the update/recall done.

yes the exhaust flap! What is the purpose of controlling this? Are there sound clips?

Purely for sound.

With stock the exhaust flap opens when the car is warmed up and in sport mode. It's closed in comfort except it will crack open slightly on overrun. The MHD feature just allows you to open and close it at will, not based on Sport mode/OEM programming.

^^^^this is correct

@Twisted Tuning have you any idea of a timeline for MHD+ and femto? I know it’s sometime in Q1 but just curious when
Thanks again

I'd like to know how you control it. Appreciate it's from the steering wheel, but the user guide hasn't been update yet. Anyone got a video?
