Paul Johnson B58 Gen 2 2020+ G20 M340, X3 M40i, X4 M40i A90 A91 TOYOTA SUPRA CustomROM TUNE

****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. 

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).
