bootmod3 CustomROM (MapSwitching,FlexFuel,AntiLag) N55-M2 Engine Support and the New Map Editor - Now Available!
For details refer to this link:
bootmod3 CustomROM Features + New Map Editor + UI Enhancements
June 2, 2021:
B58-T0-C and B58-T0-D OTS map update is out - Version 2.3
The new update utilizes an increase of TCU limitation to the ECU. This allows for more midrange torque combined with a new boost control strategy.
Moreover, the drivability has greatly improved. Casual driving is now totally different and has a stock-like feeling until pedal goes all the way down.
Ignition timing during spool has also been changed allowing for a slightly quicker spool.
Key features:
- Major improvements on drivability
- TCU limitation of 550NM has been lifted
- Boost control has been improved
- Aggressive OTS map versions now have a more deep burble sound

November 26, 2020:
B48-F-H OTS map update version 2.0 is now out!
Completely new strategy on the new OTS map has been carried out.
Torque calculation and boost control has been changed.
Ignition timing advanced has been changed as well to minimize ignition timing corrections for all the octanes available.
All this results in a flat torque band giving the user great power towards redline.
Map info:
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.
