I can see using the "valet" slot when I leave the car with a detailer to be washed, claybar'd and waxed every 6 months or so. And, I said the (crank) HP numbers were guesstimates, albeit optimistic ones. BTW, slot 2 felt stronger than 65% of Stg2/91oct. It wanted to spin the wheels with 50% pedal in comfort. And, I have an LSD.

You can not assign different stages on map slots, but, if you want different power, you can use power slider to set desired power per slot

Is that a response from BM3 or MHD!?

That's what I thought. I also asked and got the same answer.
As I complained that reducing power is (by far) not the same thing as having access to different stages, they became really defensive, on the borderline of being offensive.

Map1: ACN91 octane (poor grade fuel, California, etc). Map2: 91 octane Map3: 93 octane Map4: OEM MPPK tune I suppose a bit more useful since the map4 gets closer to stock (between stock and stage 1 for power), but I have no use for map1. |

Perfect!! All I was hoping for, almost!
BM3's setup is clearly better thought through! And ironically, MG Flasher's isn't that different too, featuring a stock map as a multimap slot too: So it clearly CAN be done. One way or the other. Too bad, MHD...

Well that sucks that MG & BM3 can do it and MHD apparently can't.
Also, I noticed that after flashing the multi-map option, my CEL no longer lights at all, except when using the map changing function. So, that's no good. I am going to flash back to single map Stg2/93oct. and hope that my CEL starts working normally again. Fingers crossed...

Well, I flashed back to single map, Stg2/93oct and my CEL still doesn't light up at all. Normally, the CEL lights when the ignition is switched on and and the goes out a second or 2 after the engine is started. Now it doesn't light up at all.
I'm going to send them an email, see what they say.

I remember that you believe that Subject to another thread. Let's not derail this one.

All these switches are useless if you have custom st3 firmware for gasoline, E40-85, methanol))
Anti-lag at 16psi also does not give any miracles)))

Bootmod3 had a great write up of how multi map works. Basically multi map uses the same base map which has thousands of settings and then they alter 50 settings on top of that for the different maps.
This can be handy when you're changing fuel grades and with the ethanol sensor there's even more flexibility. It to changes the percentage of ethanol and then uses a multiplier to adjust other settings |

However how do BM3 pack an OEM MPPSK map in a slot, it being a completely different base map?

I find it useful. This is exactly how my Volkswagen map switching worked with APR. You had stock, 91, 93, and valet modes.
I rarely used them, but it's much easier to switch maps when needed compared to carrying a laptop or flashing with your phone and hoping your battery doesn't die, your phone doesn't disconnect, you're not waiting on an app update, or heaven forbid another iOS update renders your wifi dongle useless. To MHD/BM3's point, if you have a downpipe, why do you want to run stage 1 XX octane instead of stage 2? Also if you get a custom tune, all 4 slots are completely customizeable. So if you have a pump gas and a full e85 map or a map with meth, that's very useful. |

Obviously there are different use case scenarios here. I can only answer for myself:
Quote:
I am currently driving the OEM MPPSK tune with a Downpipe. I know many others here are doing it too. Why? Higher safety margins = higher reliability in the long run. For the times when one can (or is forced to) make it from A to B with "only" 360 PS (Or actually around 380 PS with the DP). It's not very difficult to be fair And what if you have a HPFP, which can only be used in Stage 2+ with min RON 98 fuel, but are occasionally forced to use RON 95? Wouldn't it be handy to be able to switch from Stage 2 to Stage 2+ and vice versa? Quote:
The fact that both BM3 and MG both implemented a stock map in their multimap solution probably says enough about the need/market for it. And at this point I would repeat my personal view that it is not a "MultiMap" if you can only have a single Map, with different parameters. I get it that there are technical constraints. I do. But BM3 and MG seem to have found some way around them. Would be interesting to understand what/how...

This is what I expected from MHD. Unfortunately, theirs is limited to variations on a single stage, without the option to have an OEM base map.

Thinking out loud it makes me think they're only alterning about 50 parameters in their stage1 ots maps.

Not even half, but a handful. Same with flexfuel. Custom tuners have commented on this as they have a separate block for the settings that can be adjusted with these features. It's not a completely new map from the ground up. |

When MHD releases v3.61 of the app later this week, I'll reflash to fix my disabled CEL issue.
I’m planning on flashing these 4 options in the multi-map slots: 1: Stg2/91oct. 100% (daily driver) 2: Stg2/91oct. 60% (valet) 3: Stg2/93oct. 100% (max fun on pump gas) 4: Stg2/93oct. ??% (HP/TQ between the Stg2 91 and 93 oct. maps) Question: What % should I use for slot 4 to get an estimated HP/TQ rating that is in the middle between the Stg2 91 and 93 oct. maps? 90%? 95%? Some other %? If I knew the estimated crank HP/TQ ratings of the Stg2 91 & 93 oct. maps, I could figure it out myself, but I haven’t been able to find those. Anyone know what those are? Thanks for your input! p.s. I asked MHD this same question and their response was one line: "you have to try what works best for you." I understand their reluctance to provide HP/TQ estimates, but that response wasn't very helpful. Edit: Thanks to Skyhigh's bump of this thread, I found this comment from MHD: "on 98 (93oct) you can expect around 390 ST1 and 420 WHP ST2" So, if I put Stg2/93oct. 95% in slot 4, that should give me a map that is somewhere between the Stg2/91oct and 93oct OTS maps.
