Looks like @[email protected] has released a new feature:

Our update 1.52 for the MHD Flasher N54 features a new „Coolant target flash option“
You can choose between Stock, Sport and Track Mode.
The following changes were made:
Sport Mode
• Coolant normal 95c (104c Stock)
• coolant high 90c (95c Stock)
• Coolant high+kft 80c (85c / 80c Stock) (This mode is activated at full throttle)
• Amb threshold for high mode 27c (32c Stock)
• Amb threshold for high + kft 32c (37c Stock)
Race Mode (only for drag race application)
• Coolant normal 85c(104c Stock)
• Coolant high 85c(95c Stock)
• Coolant high + kft 80c(85c / 80c Stock) (This mode is activated at full throttle)
• Amb threshold for high mode 22c(32c Stock)
• Amb threshold for high + kft 27c(37c Stock)
Your car will run cooler and the oil temperature will also drop slightly

So I assume Race and Track mode are the same? I have yet to test it out.

Please do I'm curious as well. With summer basically here in the desert I'm all about staying cool.

Do note, you will take a decent MPG hit by running cooler

It absolutely MURDERS my gas mileage. Source: my wallet.

What mode do you run and any other changes or differences in driving? That does not sound right at all. There are heaps and heaps of new factory cars out there that target 90-95C coolant temp. Both my last work cars run 90C stock. I target very close to MHD's sport settings on my 335i and my mileage did not change at all when I did it.

Driving is unchanged but miles per gallon is noticeably reduced for me using the sport flash. Previously I was running the Dec '16 JB4 MHD BEF. This was my first time flashing the combined bummerboost/MHD BEF (March '17) for JB4 and I turned off burble and turned on sport cooling.

I am going to flash the sport mode, shouldn't be any negative effects right? I don't mind fuel mileage but can't see how that would be impacted?

I have a CSF radiator already, haven't really looked at temps. Hard to compare with someone unless they live in AZ. I'll flash it over perhaps tonight.
