B58-T0-C OTS map update:


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

May 10, 2020:
B58-G Stage 2+ OTS maps now available!

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)


- 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

B58-G OTS map version 2.1 is now available!
Version 2.1, May 10 2020:
- 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.

ACN91 and E30 Stage 1 and Stage 2 OTS maps has also been added

New boost and load control, making spool faster and throttle wide open!
