bootmod3: CustomROM release - Map Switching, Flex Fuel, AntiLag, New Map Editor...

Actually, based on what I read in some posts and on the wiki pages, I think this is technically possible - just not easy to do it at the end user level right now. Specifically, an authorized tuner (with access to the create new CustomROM function inside BM3) would need to create a "new" CustomROM multimap file, then basically "cut & paste" the tune files of your choice into the map slots - like the example above (with the accompanying costs to do it as described in another post).

If this is not how it works, then I believe the "catch" is that all tune maps in the map slots need to be similar tune files that share some base line elements. Remember, the tune "file" inside the DME contains over 4800 different maps/parameters that control the engine. Only a subset of those 4800 maps/parameters are actually manipulated by tuners when creating different tune files with different power levels and/or fuel type requirements. So, for example, the Stage 1 OTS map and a Stage 2 OTS map and stock map may not share enough base line elements to be bundled together in a CustomROM multimap. So this could be a practical limitation of the DME that can't be overcome - at least not yet.

I am not a professional tuner by any stretch of the imagination. What I described in the second paragraph above seems like a technically plausible reason why you can't bundle just any map of your choice. However, I hope that I am wrong as I would like to be able to bundle tune files if my choice, similar to the ones above.

That certain seems to be the case. Shame we all misconstrued what was being delivered in the promo vid back in October

And it appears in the OTS multimap one cannot individually configure the options for each of the 4 OTS slots (so can't adjust burbles for OTS Stage 1 vs OTS CS, for example). All config settings get applied to all 4 slots it appears.

Gotta keep the tuners in biz I guess

Can BM3 now integrate with the MOTIV Reflex? I believe your release says it can but would appreciate it if PTF could confirm.

“ Features in our CustomROM release have been added in a way to preserve all existing DME calibration safeties in place and integrating new and existing CANBus (PT-CAN) messages from other vehicle modules (e.g. steering wheel) and auxiliary CANBus devices.”

Is that just not in atm or not coming at all? Only these bundled maps?
I've been envisioning being able to do the following since the announcement.

Map1: Stock Map
Map2: CS stock power map
Map3: ACN91 octane stg1
Map4: Valet Mode (which was mentioned as coming)

Same for me, but insert stage 2 in Map 3 slot.

Beating a dead horse here, but this would be fantastic. If someone figures out how to do this on a end user basis, please let us know or PM me.

Thanks!

Looks like they haven't even figured out a way yet for us to bundle a custom tune and ots tune for map switching. Hopefully it's something they add down the road

So if I understand this correctly, how much additional HP/TQ will you get if you have the flex fuel hardware installed and run E85 with one of the OTS multimaps? So in other words the Stg 1 93 Oct map makes X HP on 93 Oct gas (I have this in my car now). If I put in a tank of E85, the DME using the flex fuel hardware will make adjustments in real time (adjusting fueling, timing, etc) to the Stg 1 93 Oct map to produce more HP/TQ. This map is clearly not optimized for E85, but what will be the percentage increase in HP/TQ with E85 in the tank while running this map? 10% increase? 20% increase? : ...

Solid question as Im determining if I should get whatever components are required to run the available Flex Fuel setup. If the gains are marginal it might not be worth the time/effort.

I can't answer specifically for this platform but on my SS I gained about 75hp going from 91 octane to E70 without the meth and 1 additional psi. That's about 15% or so. Just make sure you have enough fueling hardware to deliver E85. I would guess that on the S55 you could gain even more because you'll be able to add even more boost where with my setup I only pullied down to add 1 additional PSI.

EDIT: I could easily pulley down more to add a few more PSI and probably another 10% hp. E85 does wonders compared to traditional 91/93.

EDIT 2: Plus having the ability to flex really makes it awesome. If I want to take a road trip and get better gas mileage or if I just can't get E, I can easily throw some 91 in. I really can't think of a downside of a flex tune. If you don't like it, you just fill up with regular 91/93 and go on your merry way.

Here's the steps on laptop:
Flash the new Stg2 MultiMap.
Go into the LiveConfig tab.
Map-switch to #3 for 93 octane.
Set the Ethanol sensor override switch.
Set the slider to 30% (or 85% for E85).
Turn off car for 10 seconds, then start.

Worked great for me!!!
Thanks proTUNING Freaks

I thought you were running the E85 jam from Paul? Why the switch?

Because I couldn't hold any traction in the cold so I went back to 93 for winter, and just mixed a tank of E30 to start playing in good weather. My Paul tune is like 2++ and built for race only so I try to scale back the power unless I plan to use it.

I just did a successful map switch with the car running.

My Ethanol sensor setting is set to override (I have no sensor or hookup) and % set to 30.

Car was running on Slot4 (CS) and I switched live to Slot3 (Stg2 93 octane).

All done with E30 in my tank.

Ahhhhh 10-4. Here’s to hoping we can eventually use the feature of having that and ots in our 4 map pack!

Pretty excited for the new changes. Some of you guys need to read those links in the first post

Good to hear. A quick google search reveals the necessary flex fuel hardware is a $300-$350 problem. Which is not bad to have the ability to put E85 in the tank and then 91/93 oct, letting the DME make the adjustments on the fly as the ethanol content changes with different fuel ups. I would like to see the flex fuel hardware install to see just how DIY'able it might be though...

That would be awesome if someone made a DIY Youtube vid for it.

Where is BlakesGarage ? he could do it

[BYT_M4C]

I believe there is a video for the install of the Bend Calibration kit

[MINERALGREY_F80M3]

Yeahhhhh not what we expected. I was just hoping to switch on the fly from the stage 2 e30 map to stage 2 93 with anti lag in both

[BYT_M4C]

If you buy the flex controller and load a flex tune then you don't need to swap tunes to change fuels. That is the point of flex fuel, one tune to handle everything. Then have the 4 maps setup as your everyday version, a all out version, a flat torque version maybe, a valet tune, a flame tune etc..

Why would they put an ethanol blend map as a map slot when you have flex fuel?! You’re missing the point of flex fuel. It does anything from 0 to 100 ethanol for you bro, way better than doing some fixed blend
