bootmod3 for BMW F series Vehicles - General Discussion

That's interesting, what's the reasoning for not just running how it is on the street at the track as well? Decreasing the load on the driveline when it's less critical to make more power, etc?

I prefer the throttle response of the CS / CS+ maps. It makes things a lot more linear and less punchy.

Agreed, and the reason I also run CS on the track and St 1 on the street. And with the new map switching capability (without a re-flash) now offered by BM3, it makes the switch between these two maps even more ridiculously easy..

Ahhh forget about maps and just go to straight e85 lol

Car has 14k miles on it. Runs flawless. I've got charge pipes and an AA mid-pipe along with a Kies installed 4-pin crank hub. I'm planning on just doing a stage one 93 tune for starters.

I've read most of the thread and I'm curious about one thing. I've got an exhaust valve controller that is operated via remote and/or my garage door button. Should I remove that before I run the tune?

Regarding trans/diff tuning. Any recommendations?

Thanks for anyone's help.

I like the Thor App for Diff tuning. Went with the GTS diff as well as the GTS steering and that was amazing. They have transmission tunes too but I have a 6MT so didn't apply in my situation.

Haha.. Well, now that BM3 offers flex fuel control, a flex fuel kit is on my short list of mods in the not too distant future. Does that count…?

Just flashed the new Stage 1 multimap and GTS DCT today. Since this is my first go at it I don't really have anything to compare it to, BUT the fact you can switch between ACN91, 91, 93 and CS tunes all with the cruise control buttons in a matter of seconds is extremely sweet. Not sure I'll ever do it, but all the maps are flex enabled and all that needs to be done to activate that is buy and install a flex sensor like Zeitronix ECA-2 and it auto adapts.

I did have a moment of slight panic while I was running logs after the flash with my laptop plugged in. Had no idea that the collision and pedestrian systems are inoperative with an OBD-2 device active.

Make sure you get the bend kit with the fuel filter… it might save you some failed injectors and a hpfp down the line lol

Yup, that is the one on my list…

[Trevorstein]

Consult...

I may be just losing it but, Does everyone now have a 6th map ("stock" included) in "My Maps"?

In my case:

* "Stage 0+ (M4 GTS) **** Map generated using CustomROM Conversion"

It seems to be configured ("version") exactly like the like titled OTS map I already have there.

I truly don't remember this being there previously.


Cheers!

So can you flash the new Stage 1 multimap without installing the flex sensor first or can you turn on/off flex fuel enablement in the config settings?

Also I understand you switch tunes on the steering wheel but how do you know which of the 4 different tunes you are actually in, is there a visual indicator?

Yes you can flash the tune without the sensor. All 4 maps included in the multipack are standard octane and flex enabled as I understand it. Based on what I read on BM3's website about the update, the tunes will auto check for a flex sensor. Without one they are standard octane, with one they will adapt to the sensor's assessed value of ethanol in the mixture. I currently am running it without a sensor.

To switch, with the engine on, you press and hold the cruise resume button for 3 seconds. The tach will then go to 1, 2, 3 or 4k RPM indicating slots 1 through 4. 1-ACN91, 2-91, 3-93, 4-CS. From there, use the cruise speed adjustment toggle (left side of wheel) up or down to select the tune you want. The needle will move as you toggle. Then press and hold resume for another 3 seconds to choose. It will take about 1-4 seconds for the tach to return to the current engine RPM signaling that the switch is done.

It's impressive to say the least. Big fan.

If BM3 detects a flex sensor (Zeitronix), it will basically throw map 1-4 out of the window and go to an ethanol default setting. Depending on your ethanol content, it will self adapt and add power accordingly - up to 540 whp at max ethanol content if I recall correctly.

[TopJimmy]

The flex tunes don't ignore or change the map slots. When the BM3 tune starts with the car it resets the E% value to zero, then checks for a sensor reading and loads that into the E% spot. You can also LiveAdjust the E% value (each start) in case your sensor reads wrong or even if you don't have an E sensor.

If the tune makes use of the E% value (a flex fuel tune) then it usually alters fuel volumes/pressures and spark timing tables to match up to the fuel changes to try and make more power/torque.

On car on/start the picked multi map slot # shouldn't change unless you just reflashed, then it defaults to 1. The fuel type named for a flash map usually determines the max fueling, timing and boost chosen by the person who wrote the tune. So if you fill up on 93 gas but picked the 91ACN map slot you won't get more power until you switch it.

Guys my car has istep of 2016 and I want to update to lastest without locking DME. Is it safe?

I think you'll lock the DME.
Ask PTF first.

Pretty sure being 2016 you’re fine and won’t lock yourself out

[FrankMstein]

Searched but could not find it. Is there a way to recalibrate the sport displays to match my dyno results?

What about a 3/2015? Want to use istep+.

Why hasn't BM3 been made to be compatible with Apple CarPlay?

Wouldn't it make sense to have live engine parameters right on the dashboard? I think it would be a lovely feature.
