Since 2016 Paul's customers have achieved numerous 1/4mi, 1/2mi, 100-200kph, 60-130mph, and road course world records with various configurations of S55 and B58 equipped BMW's and Toyota Supra's.

****NEW CustomROM Features Available Now!  Our first release of the bootmod3 CustomROM is now ready for the B58 Gen 2 engine vehicles. 

 

Anti-Lag  

All new CustomROM tunes come with our fixed OTS Rolling Anti-Lag (13-14psi) at no charge.   Fully customizable Anti-Lag is an available option for $200 and includes various tunable settings and safeties such as Anti-Lag Boost, AFR, min Accel Pedal required, Max. Time in Anti-lag mode, Engine Speed, Min and Max Temperature thresholds for Oil, Exhaust Gas Temps and others.  **note all Map Switching slots 1-4 share the same Anti-Lag settings.

Map Switching 

This is what to expect from Map Switching:  Initially you’ll buy a new CustomROM tune from us,  Paul and his team will work to dial the tune in on the mods and fuel type you choose.  Next,  you’ll have 3 additional optional slots, sold separately,  to have variations of this map. 

Some examples of great uses for map switching are to have street or drag map variation with torque by gear limitations for different tires or road surfaces,  a kill map with higher boost/timing to be used on occasion, a daily map with reduced boost, valet, or flames map, etc. 

What NOT to expect about Map Switching:  These map slots are not full separate custom tunes.  They only adjust certain things about the base map such as boost and timing but do not include everything that can be adjusted such as valve timing and detailed boost control, etc. Map switching is great but not as powerful or precisely adjustable as having separate tunes.  Separate CustomROM maps are needed if you are wanting to fully optimize all the tables and capabilities for each specific fuel type.

Flex Fuel 

A Flex Fuel tune will start off as a low ethanol pump gas or race gas tune and then dynamically adjust boost, timing, AFR, and fuel supply depending on how much ethanol content is added to the fuel tank.   To allow for Flex Fuel tuning, an Ethanol (alcohol) fuel sensor and an Ethanol Content Analyzer (ECA) CANBus device need to be connected to the vehicle’s PT-CAN. To use Port Injection with a Flex Fuel tune, we recommend a PI controller such as the Motiv Reflex which adjusts the port injection output based on the ethanol content from the sensor.

**B58s require upgraded fuel system components that are sufficient to support the ethanol % that you intend to use with your Flex Fuel tune. (I.E. upgraded HPFP, LPFP, Port Injection, and or Methanol Injection).

bootmod3 CustomROM Release - BMW S55 Engine

Custom tuning for B58 Gen 2 Stock turbos/stock fuel system is available for pump gas, race gas, and ethanol blends with methanol injection.  Results will vary depending on the fuel used and the weigh/traction of your particular N55 model.

With Paul’s Stage 2 93 octane tune on stock turbo / stock fuel system you can expect 500+ Whp on an average reading Dynojet in good ambient conditions.

Upgraded turbo and ethanol tunes for B58 require upgraded fuel systems, port injection, and or methanol injection.
