- Changed injection window to prevent a torque limitation.
October 31, 2023:
B58-T0-D OTS map update:
This new update includes a remake of the boost control and burble configuration.
Boost control has been changed so boost reaches its target quicker than the previous OTS map versions. Moreover, boost is kept close to its target all the way to redline resulting in a slight power increase.
Burble configuration has been redone to work on non mild-hybrid and mild-hybrid software versions.
September 28, 2023:
S58-1 MultiMap OTS map update:
This new update brings more power for users utilizing a flexfuel sensor on their S58-1. Moreover, maximum power is now achieved at 50% ethanol to prevent HPFP from crashing at high ethanol contents.
Moreover, users who had OPF cars experienced a load limitation at higher RPM, this has now been lifted to match the OTS map load limit targets.
Version 1.1, September 29 2023:
- OPF load limitation lifted
- FlexFuel fully revised
- Higher FlexFuel ignition timing targets
August 22, 2023:
GEN2 B58 OTS map update
Various changes have been done to our new OTS maps for the B58 gen2.
This includes the intercooler pump is more active over stock, vanos changes to provide more power in the midrange and topend.
Burble activation has been fixed for mild hybrid cars, due to newly introduced limiters and activation switches for the mild hybrid cars, this was not present in our old version of OTS maps.
Moreover, a boost pressure plausability code would show up on mild hybrid cars as well, this has now been addressed.
Map notes:
- Vanos optimised
- Torque limitation fix
- Burble fixed for mild hybrid
- Boost pressure plausability fix

S58 CustomROM Release
S58 CustomROM support is Now Available !
Over the past year we've worked tirelessly to build significant automation that would allow us to port our CustomROM features across software updates as they get released for vehicles we support. We applied it to the S58 and managed to add support for all 8 S58 software versions including all G8x M3/M4 and G9x X3M/X4M.
FlexFuel, AntiLag, MapSwitching, LiveAdjust Tuning, In-Dash Ethanol Content Check, and close to 5000 tuning tables available in the bm3 Map Editor.
🔸Any new OTS Maps available?
Two new MultiMap OTS maps, Stage 1 and a Stage 2. Each MultiMap contains 4 steering wheel switchable map slots. FlexFuel and Antilag are built into all of them and scale from 0 to 100% ethanol.
🔸Can I get this if my DME is currently LOCKED and requires a FEMTO Unlock?
Yes. You need to purchase a BM3 license, activate your bootmod3 software license, and then send your DME to Femto. We provided Femto with means to load BM3 CustomROM software along with our Transmission Limiter Bypass. Once you get your DME back from Femto, it'll have the BM3 CustomROM on it with their unlock.
🔸Can I get this if my DME is Femto UNLOCKED?
Unfortunately, due to specifics around the Femto unlock, you will need to have your DME resent to Femto for CustomROM software to be applied along side their unlock. Your DME would lose its Femto unlock if we allowed a full flash of the software to be done. If you were to flash the MultiMap without resending it to Femto, you will simply have MultiMap's map1 power available and no CustomROM features.
🔸Do I need to clone my DME for this?
No.
🔸Can I get this if my DME is OBD or Bench unlocked (older X3M/X4M)?
Yes, flash away.
🔸Is there an S58 Flex Fuel hardware kit?
Our S58-specific Flex Fuel kit hardware is on the way so be on the lookout! Any other flex fuel kit based on the off the shelf Zeitronix ECA2 CANBUS controller can also be used. In the meantime, you can use the LiveAdjust screen in the app to scale your ethanol content on demand.

Bootmod3 B58-G OTS map update - Version 2.2
Power increase / Boost pressure increase / Boost control changes / ignition timing changes are all part of the new version 2.2 B58-F OTS maps.
When comparing the version 2.1 and 2.2 of the Stage 2 93 octane OTS, a noticable difference during spool is shown (torque spike is gone). The torque band is higher throughout the entire RPM range.
Next up we put an upgrade HPFP on the M140i and went on for the Stage 2+ E30 octane OTS. Power was improved throughout the entire RPM range as well.
Many users have been asking for a Stage 2+ E50 octane map, we made that as well :) On stock turbo, this car pushed out 514WHP and almost 600WTQ!
Stage 2 OTS maps were tested on a M140i with a high-flow downpipe and exhaust. When doing the Stage 2+ maps we installed an upgrade HPFP.
Version 2.2, December 14 2021
- 550NM Torque limitation from gearbox disabled, this increases torque over the previous version for those without a TCU flash
- Torque is calibrated for higher load
- Ignition timing tables have been revised to reduce ignition correction during spool
- Overboost at lower engine speed during full load has been addressed
- Boost pressure has been increased over the entire RPM range providing additional power

S58 OTS map update is out - Version 2.5
We made a change to how drivability is on the update, slow/part throttle driving will be more stock-like.
Fuel tables have been modified on pump gas OTS maps to run slightly richer AFR targets in higher RPM/Load area.
Moreover, the S58 Competition LCI Stock tune calibration has been added. This produces slightly more torque (650NM) than the non LCI version from factory.
Version 2.5, November 4 2021:
- Part-throttle drivability improvement
- Richer AFR at higher RPM/load
October 27, 2021:
B48-F-L OTS map updates are out - Version 2.3!
- Many changes have been applied on this update. Biggest change is an increase on the internal torque limitation, this allows the OTS maps to make power - all the way to redline!
- AFR is now a tad richer, this works much better on all octanes, minimizing ignition correction on lower quality fuels.
- Boost pressure target is different, the OTS maps handle that by a limitation in pressure ratio instead.
August 9, 2021:
B48-T0 OTS map update is out - Version 2.0
- CHN91 (Chinese 91) OTS maps have been added for poor fuel quality with lesser ignition timing and slightly less boost pressure over the ACN91 OTS maps.
- We also added E30 OTS maps for those who'd like some more power on their 4 banger
- AGG OTS maps have been optimized for burble so they are really aggressive this time, duration and aggresion have been changed to suit the map name.
- Drivability overall have been improved, yet with better throttle response. This is done through a different torque strategy compared to previous maps making the car feel more comfortable during slow driving but a beast when going WOT

bootmod3 CustomROM (MapSwitching,FlexFuel,AntiLag) N55-M2 Engine Support and the New Map Editor - Now Available!
...
Version 2.0, November 26 2020:
- New torque structure
- Ignition timing revised
- Boost control revised
- Power increase
July 3, 2020:
S58 OTS map version 2.4 is out!
After gathering tons of datalogging from users across the world, even more improvements were found, applied and tested
These findings resulted in a smoother boost curve at high engine speed allowing for a more clean ignition timing curve thus more efficient power, especially on stage 1 cars with stock hardware.
Furthermore, burble is now working better for cars with particulate filter (OPF).Version 2.4, July 3 2020:
- Boost taper at high RPM fixed
- Unstable wgdc at high RPM fixed
- Burble activation for OPF cars
The stock turbo can flow on the B58, but the limitation is the HPFP, with the B58TU HPFP or Dorch Engineering HPFP you can unleash the true beast of your B58!
Boost pressure is around 20 psi
Required hardware:
- High flow downpipe
- Upgraded fuel pump (Dorch Engineering or B58TU fuel pump)
*** AFTERMARKET HPFP MUST BE SET IN THE CONFIG ***
- OEM BMW B58TU Fuel pump part # 13518631642 - This fuel pump is plug and play, Map Configuration should be left unchanged or set to OEM
- If using the Dorch Fuel pump, Map Configuration for the HPFP should be set to DORCH
We recommend XHP transmission flash to take advantage of the high torque
- Boost and load control changes
We spent a lot of time on boost and load control on this Version 2.1
Slightly powerincrease on the topend.
Some users would experience overboost in the lower RPM range causing a midrange to drop slightly in power.
This should now be resolved.
