I can't say I have been looking forward to the introduction of Multimap as much as many, but I was a bit excited as well.... until I realised that it does NOT allow having different Stages, only a single stage with different settings in every slot (Fuel type, burble settings...)

In reality it should be called "Stage Presets" instead of "Multimap" as the latter is misleading.

I wonder what you guys intend to use the so called Multimap for!? To me it appears nearly useless! It's not everyday one changes fuel types (and even if, putting another type with even little residues from the old creates a mixture, so it will take time to transition). And simply having different burble settings is rather just... childish...
What is the intended application of this, without access to different stages and actual maps? Provide real-life examples please of how you would take advantage of it and for what?

[mike@x-ph.com]

I did not know MHD does not allow storage of different stages.

But even they do, why would you want to change stages? I would run the highest stage recommended for your mods.

I would have two maps with different fuel 91/93 and E85 if you have access to it and two maps with aggressive burble if you like the burble sound.

and maybe a custom map that's too aggressive for daily driving so you can use only when you need to

[Skyhigh]

Your scenario may be applicable to the aggressive tuners amongst us.

Since I often simply commute (with other people and pets in the car), I would keep the car in Stage 0+ or Stage 1 for all those trip where I simply do not need (or cannot take advantage) of a higher stage (sort of like Comfort vs Sport mode), for increased comfort, reliability in the long run or even for impromptu police controls. There is nothing wrong with those Stages after all. It would have been great to be able to jump to e.g. Stage 2 on demand and back.

I have no intent to use a custom map, I don't have access to Ethanol and am not intending to ever use. I would use the highest Oct fuel available, but that's not a regular thing I need access to from the steering wheel, for the occasional change of fuel type.

Having different burble sound levels is childish IMO. Pick one. Done. There is enough versatility through Comfort/Sport in that regard.

What I wonder about is whether there are technical reasons for not allowing Stages to be set as (multi)maps (which is what the name suggests on first place!) or it is simply a concept which is not well designed (yet)? If one can have a custom tune (effectively a completely different map) as a multimap preset (if I understand that part correctly?), why should it not be possible to have a different OTS Stage too?

[mike@x-ph.com]

Not too sure, to be honest, what's stopping them from offering the different stages. Im not familiar with MHD since I do not sell their products.

[T_H_O_M_A_S]

you can have one slot with for instance stg2 93oct and set the power slider to 60 percent , then it will drive as stg0

[Skyhigh]

I know. But I don't need it to "drive like". I would like it TO BE... In every respect, not in terms of maximum power delivery.

MHD already suggested this workaround but that's just silly.
If I get stopped by police who would want to measure emission, noise, etc. on the spot, I may have no luck explaining, that my tune is tuned down to "drive like" a non-tuned engine.... you see my point, I hope Besides that, in terms of long-run reliability, it is certainly not the same for the engine as an altogether less aggressive map.

some more info

a cop can check it ? , are they certified for such conducts ?
if one has zero knowledge about a car. and besides you can tell him what you want right ?

[Skyhigh]

In Germany they can and are allowed to measure noise and gas emissions on the spot. If you fail - you are sent for further inspection for illegal modifications. No need to have knowledge - they simply compare numbers to what's in the type approval.

Explanation like "But I did dial down my max power of my tune because this is all that MHD multimap allows me to do instead of switch to an actual stock map" would not help

I simply find MHD multimap disappointing and (potentially unnecessarily) restrictive. That's all.
Was curious what people are actually gone use it for with the current restrictions. (Please don't say different burble settings!)

[T_H_O_M_A_S]

i thought it would be possible also to switch between stg1 and 2 or else , im prolly not gonna use it anyway . i might give it a try to see what the power slider does, making multiple runs on a dragy with every slot ranging from 100 to 70 percent in 4 steps . i dont care about the antilag feature

cops will come after you if you make yourself noticable in town . my car isnt that much louder catless of catted when driving normal in comfort apart from the smell . in dsc off and sport setting on the zf box , is waay too much . then you will draw attention . now im only using xhp stg2 at the moment . the max makes the nicest wot shift sounds in comfort with zf box in sport . the other settings are much louder and too much bangs off throttle . i have zero burble settings in mhd

I think the multimap settings that are available currently appeal to a much wider audience than what you are describing. I kind of doubt flashing a lower stage would affect emissions or noise level at more than a negligible amount. Hopefully you have your stock cat and exhaust if that's something you're worried about... Fuel changes should be the main purpose of the multimaps IMO.

[ATL_Nak-Muay]

Is case the wife/kid/buddy wants to drive, you can hit that 50% power valet mode on them. Differents spicy for diff days. My tuner always gave me high boost, low boost, and valet when I was using the Cobb accessport's on prior vehicles.

Potentially. I am therefore trying to understand what people intend to use multimap for. No sarcasm meant.

What is the exact purpose of on-the-fly change of fuel settings? I thought one needs to refuel (potentially more than once...) to acquire and make use of a different fuel type And how regularly do people actually change fuel type? (For me it is on average a once a year event, in case I am somewhere on a journey and forced to use lower octane temporarily).

I think of setting my Tuning Stage to match my engine’s hardware upgrades. And the Multimap as variations on that best HW tune. So I use it like this:

Map slot 1: Stage 2, 91 oct, 100% power (Normal)
Map slot 2: Stage 2, 91 oct, 85% power (Snow)
Map slot 3: Stage 2, 91 oct, 60% power (Valet)
Map slot 4: Stage 2, 95 oct, 100% power (when I fill up for a fun weekend with Race gas)

If you typically run 93 or 95 oct, you could do the opposite to me in Slot 4, and use a slot for 91 in case you ever have to tank up with the lower stuff on a trip…

I’m not running E85 mixtures, and don’t tweak burbles, etc. on the other slots.

[Wires]

Oh interesting. BM3 has a multi-map, but it's basically one stage, with different octanes. So if i couldn't get 93 octane, I could "on the fly" downgrade to the 91 octane map. Catch22 is 91 is very common, anything higher is not, so I just stick with a single stage 2 91 octane map.

Hm. I guess your setup could be of some use to higher powered RWD vehicles.
XDrive on contrary is always in "Snow" mode, irrespective of the power, no point of any reduction We don't have valets in Europe, so that takes that one out too Fuel change is clearly one thing, if that is a somewhat regular event for some...

Exactly the same with MHD. It looks like MG Flasher however have made provisions for different Stages within the slots. Maybe just a "stage-alike" table of the same map, I don't know.

I've been waiting for map switching, but this is a little disappointing. I thought it would be any 4 OTS maps. I was planning on:
OEM+
Stage 1, 91 oct.
Stage 2, 91 oct.
Stage 2, 93 oct.

I guess now I'll just do:
Stage 2, 91 oct.
Stage 2, 93 oct.

When I heard BM3 was doing multi-stage, your initial thoughts is exactly how I'd want my multi-stage to look like. Maybe pop a request into them and see if they will add one for that?

[T_H_O_M_A_S]

i can install the multi map , but i change change any maps
it stays in slot 4 all the time , regardless how many times i press the lim button

[IMS-340C]

Try pressing LIM twice and while the car is stationary.

[T_H_O_M_A_S]

not handy while driving ,

but according to mhd enthousiasts page op fb , there is a small bug with the lim button , it will be fixed in an upcomming version

[PeterWT]

So, these are the Stage 2 slots I flashed today. The HP numbers are my guesstimates.
91oct, 100% (~400HP) (daily driver)
91oct, 65% (~260HP) (when I need to leave the car with someone else)
93oct, 100% (~450HP) (when I want max power)
93oct, 95% (~430HP) (not sure if I'll use this, but wanted to put something in this slot)

[Skyhigh]

So, if you don't mind me asking, how often do you foresee changing between your Slot 1 and Slot 2 and between Slot 1 and Slot 3?

If I imagine a similar setup, in my case it would be:

Slot 1 to Slot 2 - unknown. Usually if I ever let someone else drive, it is to demonstrate capabilities, not disabilities. Maybe when dropping off for maintenance (which may however trigger a false response if someone thinks that something is not right with the car So let's say once every 2 years.

Slot 1 to Slot 3: I only get access to higher octane when going abroad. Prior to COVID that would be twice a year on average.

P.s. MHD Stage 2 93 with 450HP!?? Dude…. Wishful thinking
