I got it back from the shop and they said it wouldn't fit anymore and I haven't tried.

I believe O2 sensor bracket has to be cut/modified?

How’s Stg 2+ MM OTS v1.2 working for all the stock turbo guys?

not apples to apples, since i am on m235i (n55 ewg) stage 2+ MM v1.3, but working as it should on e30 map, 93 map, and flat torque map.

you looking for something specific?

here's my latest logs (back to back, first with 93, then filling up to about e40)
using WMI
93 map: https://www.bootmod3.net/log?id=6468...90c605604263f3
e30 map: https://www.bootmod3.net/log?id=6468...729beaa27d4206

Nice, but why the low timing on the 93 map? No time to adapt?

that's just what the tune is, not an adaptation issue. you can see there were no timing corrections on cyl 3-6

Looks good. Here’s my v1.2 log.
https://bootmod3.net/log?id=6471344fc090c66243bfeef0

Looks like 1psi less boost than v1.1 to help the stock turbo guys.

i'm seeing quite a bit of difference, is it because you are on flextune at e50?

your target boost is less than mine, your timing is way higher, and your lambda is quite a bit leaner.

Yeah, the N55 and M2 OTS maps are a bit different. I am getting more timing advance from the PTF Flexfuel sensor and E50.

I've switched between the maps before and felt the difference but hadn't logged them all together. Pretty cool to see the differences in boost and timing targets bn the maps, and associated changes in HPFP angle, MAF/RAF, WGDC, clutch torque, etc., just from a quick map switch via the steering wheel while driving!

I keep the Multimap in Stg 2+ E30 map by default, but it'll come in handy to quick switch to the 93 or flat torque maps when I'm letting someone new drive my car, or if I need to dial back power on a super-hot track day.

this is with flex fuel enabled?

if so, then this is saying that even with flex fuel feature enabled, and you have e50 fuel in the tank... then it matters which map you select?

i would assume then if you had 93 oct in the tank, then you should NOT be running the e30 map even with flex fuel enabled? this can be dangerous since the multimap for f3x/f2x defaults to map 1 (e30) and an unsuspecting person could be fueling up with 93 oct and be none the wiser

With flexfuel kit, Multimap will auto adjust and downgrade torque/timing/fuel to lowest octane map

hmmmm, mine still targeting 21+ psi. v1.2

Log?

There’s a different tune strategy with v1.2. The target is there as kind of a ceiling, but other parameters are now being used to let actual boost float to a max level while keeping the turbo in its efficiency range.

I have a v1.3 map that does that for my TTE460, just haven’t had a chance to post v1.1, 2, and 3 up with logs and discussion to compare. Should have time soon.

I deleted, I'm running pump gas cycle right now, will do one when filling E50 next time.

I remembered cuz when v1.2 came out on early april. I flashed immediately. BM3 has a bug for dorch stage 2 hpfp config. Car is undrivable, I think I posted in this forum. Then I worked with them and did a log with their test map on 04/26. They updated it couple hours later.
https://www.bootmod3.net/log?id=6449...729bd12ab6de7f

This is the only one I saved on 04/26, Ignore how bad the timing is. I did this just to make sure hpfp is functioning and send it back to ptf.

[TheHaze]

Hey guys. I'm currently running the multimap stage 2 tune and seeing lots of timing corrections/knock occasionally. I didn't want to derail this thread, but if anybody would like to take a look at my logs and let me know your thoughts I would really appreciate it.

I don’t seem to have v1.2, but I just ran v1.1 on track with ~E47 in cloudy 65 degree weather on my stock turbo. 5 sessions and everything ran beautifully, although I haven’t done any logging. It was incredible being able to keep up with a stock G80, older model R35 and a GT4RS (kinda) on the straights.

I was going to install the PS2 I have and run this tune, but I think I’ll try out the Pure500 instead—I love the stock turbo response, but I’d like a little more peace of mind and top end power

Yes, you're right, just filled up with new E45 today and did a short log on the street, highest target is 20.5psi and boost is floating as your log shows. V1.2 btw. Thanks

I am just curious if Bootmod3 is maintaining consistency with version numbers and features across similar engines. That hasn’t always been the case so the software might be different say between the M2 and the 335i even though they both had N55 EWG engines. I try to read both forums but I can’t always tell if the version numbers and discussion applies evenly to both.

The MultiMaps for the 335i N55 EWG currently look like this below with the version numbers and the Map slots. Are they identical for the M2 N55 EWG?

BM3 MultiMap Stage1 version 1.2
Map1: ACN91
Map2: 91
Map3: 93
Map4: M2 N55 stock power level

BM3 MultiMap Stage2 version 1.2
Map1: ACN91
Map2: 91
Map3: 93
Map4: M2 N55 stock power level

BM3 MultiMap Stage2+ version 1.3
Map1: E30
Map2: Racegas
Map3: 93
Map4: Flat Torque Map (500NM)

They’re different. Your v1.3 map list mirrors what the M2 Multimap has always been.

Altho, our v1.2 lowered boost some from v1.1 and changed the tune approach so it’d work better with stock turbos (even tho v1.0 & v1.1 worked fine with my TTE460).

Finally had a moment to post logs of the v1.0 multimap vs v1.2 vs a Stg 2++/3 version that Halim gave me for my slightly larger turbo.

Differences:
Stg 2+ Multimap v1.0 pegs boost at 20.8-psi thru the rev range. My setup could hit that no problem, but Halim released v1.1 & 1.2 which changed the tuning strategy so that the guys with stock turbos could run the Mutlimap with no issues. It means a little less power for my setup (and why Halim gave me a Stg 2++ Multimap to use), altho, I potentially like the tuning strategy a lot more for the track.

You'll note in the Stg 2+ v1.2 and Stg 2++/Stg 3 Multimap logs that the tune is no longer pegging boost, instead boost is higher at lower rpms and drifts lower in higher rpms (3-4psi lower at redline), keeping the turbo in a higher efficiency zone & lower WGDC in upper rpms. For me, that means I should be generating less heat on track, albeit a little less power, but probably worth the trade off.

Hi guys. I just installed Dorch stage 1 hpfp and flashed bm3 stage 2+ multimap. İ do have a flex fuel sensor and i have E34 in the tank. Went out to test the car on the E30 map (first slot). Was doing a 3rd gear pull and even though the car pulled hard I was getting what I would describe as "hiccups" from the engine - a few times during the pull. First I thought it was wheel spin but then after doing couple more pulls I figured it's not coming from the tires. I haven't done a log yet but I will do it on my next drive when there are less cars out. Has anyone experienced this or has any idea what it could be?
