bootmod3 for BMW F series Vehicles - General Discussion

Maybe you have a boost leak or intake leak somewhere?

[TheONE24]

I would imagine it would throw a different code that would be readable by a standard reader for a boost leak. On my N54 I had boost leaks all the time and it would still be driveable but in limp mode. This seemed like limp mode but it did nothing when pressing the gas. This seems like a fuel issue possibly to me like the error states. LPFP from what I'm finding on other models. I've flashed back to stock map. I will run it hard this weekend to try and get it to pop back up so I can take it into the dealer. I was going to take it on a trip tomorrow but now don't trust the car, which is 100 percent the reason I jumped into an M4 from the 335i ironically.

Had that error pop up a couple times at the track, mostly on really hot days. Engine oil and water temp were fine, so it wasn't that, but I suspect the fuel pump might be having issues keeping up at really high boost (I run BM3 Stage 2 91) in hot temps.

Every time it happened (all 3 times, I think), I pulled off into the hot pits, turned the car off, turned it back on, and everything was good.

My 10k service came due, so I flashed back to stock last night (from OTS Stage 1 to Stock + DME Locked)

After flashing back to stock, the car was throwing a Fuel pump code. The car would also loudly run the fuel pump when I would open the door or trunk.

To correct the issue (and clear the code), I used the "Online Recode" option in the BM3 application. Its found right under the Flash button.

I'm still confused why people pick CS maps over stage 1?? isnt stage 1 faster than CS???

You answered your own question. More power <> a faster car if you can't put the power down.

The stock power levels are already borderline too much to fully use on the street. Stage 1 seems like it would be extremely frustrating in actuality as you'd constantly be struggling for traction.

The car needs more top end, not more mid-range. The CS+ seems like the very upper limit and even that probably needs boost reduction in 2nd to put the power down in warm/dry conditions.

20% boost reduction for 1st and 2nd gear in the winter.

You nailed it, CS+ is great for every day and if I know I’ll be doing high speed pulls or something, that’s when I switch to the Stage 1 map.

This was my experience on track with stage 2. For that reason I dropped back to the CS map. No problems at COTA earlier this month.

Thanks for the info Dave. I'm running the exact same map with catless downpipes. I flashed back to stock and ran it really hard this weekend in all aggressive settings and couldn't get it to happen again. When I did have the issue friday I was getting on the highway and punching it pretty hard in sport with transmission setting 2 selected. I wonder if it's something with this particular map? I've noticed what I now believe to be this happening before when I would randomly hit the gas either at a stop or even while running in auto mode where I just figured the transmission didn't react in time and the car seemed to just not respond to stimuli but only for a second or two and then it was fine. In particular it happened friday morning when the car was still really cold. I will probably wait a week and flash back to that map. I haven't really messed with data logging but I'm guessing it probably won't help unless I just so happen to have the issue occur while I'm logging if I understand it correctly. I wonder if there is anything else I can do to see if my LPFP is going bad.

My car is a manual, so that might make a difference. Also, I do have catless downpipes, same as you.

Hi all, I wanted to get some opinions on my Data Log. 2016 M235xi VRSF DP, intercooler, charge pipe, BM3 Stage 2 93 octane. Three screen shots of a 60-110 mph run. Appreciate any tips or if you see anything.

[swifty]

Has BM3 provided the option to keep valves open in Efficient mode as well.

It would be great to have this for members residing up North who run in Efficient mode more frequently in winter but want to still hear the exhaust.

[Temper Tantrum]

Sick and tired of the cold start, so going to pull the trigger with BM3.

Is it simple enough now to mod your own stock map? I take it you will end up with 2 stock versions under 'my maps'. One edited and one standard?

I have catless dp. Intakes and charge pipes go in next week.

99/100 with downpipes are on STG2 or higher
Intakes is a waste of money (I would of used that spare for Custom Tune or Tires instead)

Custom tune will come with Pure Turbos 😈.

New tires will come after I burn these ones up on stg2 tune and get the turbos on 😈.

Not seeking power with intakes.

how long have you been running this tune? your STFT seems to be greater than my logs, do you always get such large corrections?

after taking a look at some of mine, i'm usually .96 +/- .02

I only have about 500 miles on this tune. The STFT makes changes every time you drive, it's always been around that .95 I'm no expert at all

0.88-1.10 is where u want to be, FYI I recommend joining the FB Group and posting your question in F30 N55 section better answer than in F80 S55

-12% to +10% stft is normal for a tune that has adapted after 500 miles, assuming fuel is consistent?

Just loaded up my first BootMod3 map , sticking with the CS map for winter and I'll move to a Stage 1 map once I can put the summer tires back on. What a great platform! Burbles, to me really add character to the exhaust note that was lacking on my bone stock non zcp M3. I wouldn't mind the ability to add a little "gunshot" pop to the sport+ setting in the future.

Even with the CS map, I can feel a seat-of-the-pants difference in the midrange torque in 3rd gear.

It's only December and I'm already looking forward to spring and getting some sticky tires on this thing.

You should be able to go into the map configuration menu (when you click on the map you want to flash, click on the gear icon at the top right) and adjust the sliders for the burbles for Sport and Sport+ separately. Try a high "aggression" (like 5) with a very short duration (0.3 or 0.4 seconds) and you'll get just one or two loud gunshots each time. How loud will depend on your exhaust setup. If you're saying "gunshots" to mean lots of them and not just one or two, set the duration to be 1 or 1.5 seconds and keep the aggression high.

I have mine set to only burble with an aggression of 3 for about 0.5 seconds and that's perfect for me. I also set it to only burble if I shift past 3,500rpm so it isn't doing it when just cruising around town.

Isn't aggression 5 the OTS default setting? I have it at 5 and it's not aggressive at all. I'm running just the AA midpipe and can't hear it unless my windows are open.
