MPPSK paired with MHD
Hi all
I recently purchased a 440i GC and about to fit a MPPSK system to it. I was wondering can I just fit the exhaust and use mhd to flash the MPPSK stage 1 on it without BMW putting on MPPSK software on my car? If I were to get the MPPSK + tune, and then I flashed MHD Stage 1, would that change the function/sound/burble settings of the exhaust given that I'm changing the tune? Sorry if the questions are confusing, just trying to get my head around it |

MHD would override the MPPSK tune. If you just get the exhaust and use MDH it would be basically the same.

MPPSK Exhaust (Note: not sold separately from the dealers) + MHD MPPSK tune = MPPSK - vehicle warranty (if still existent).
Not sure why you would want to do that. Either go full/legal MPPSK from the dealer, or exhaust (Yes, the mppsk one is a great one) + Stage 1 or Stage 2 tune.

Yes. Ethanol 30% blend won't hurt

You can flash Stage 0+ with MHD, which should be the MPPSK tune itself, incl burbles.
Or you can have another OTS stage and set the burbles manually to match MPPSK or your liking.

I am also interested if its possible to install MHD on B58 and RETAIN ORIGINAL MPPSK burble settings. This is what my purchase decision hinges on. No, you CAN NOT configure MHD burbles to be the same as the MPPSK defined burbles.

Trial and error. I personally have the MHD burble settings fully off but still get a nice bang on upshift in the high rpm. All personal preference.

Do you have the MPPSK on your 440i? If so, if you flash a MHD map with "burbles" unchecked, do you still have factory burbles? On N55, this is true. I am curious if it is also true on B58

I am interested too, but why don't you ask MHD directly?
Let us know what the answer is.

on Bootmod3 you can choose to keep the oem burbles (MPSSK if you have that installed) or BM3's own default burble setup or a fully customized burble setup with any of the flashes.

Correct, un-checking burbles in the MHD options will use stock burbles.
Anyway MPPSK burbles sound terrible, I replaced it with X3 M40i burbles and the difference is night and day.

I must say, I am puzzled about how this works, technically….
MHD replaces the stock ECU software. How would it "overtake" specifically the "OEM burble settings" depending on whether there was basic or MPPSK map on the ECU!?

I'll explain more...
MHD does not replace the OEM tune, the installed MHD software re-direct the DME to read from another section of the DME memory which has the OTS or custom tune. MHD OTS tunes use a stock *40i tune and heavily modify it, so if you have MPPSK you will have stock *40i burbles. Un-checking the burbles in the MHD options does not mean completely turning off burbles, it means using stock *40i burbles as it is (NOT MPPSK) If you want MPPSK burbles you have to go custom tune and ask your tuner to copy the MPPSK burbles tables and paste it to the new custom tune.

Which one is it ) Clearly MHD's answer is more likely to be correct and I have seen that answer before. (Hence my question how it works and how it distinguishes between what stock map (and burbles) were previously on the car.

P.s. another related question I have seen being asked is what does one return to if you chose to return to stock and had MPPSK before MHD??
If not mistaken, MHD brings you back to whatever was there before, hence MPPSK? Probably related to the definition of "OEM" for Burbles….
