PJT CustomROM, Flex Fuel Tunes S55

****NEW CustomROM Features Available Now!  Our first release of the bootmod3 CustomROM is now ready for the S55 engine vehicles while we continue to work on adding these features to other vehicles in the bootmod3 lineup. Changes done for the S55 are being ported to the N55 vehicles followed by the B58.

Anti-Lag  

All new CustomROM tunes come with a fixed OTS Rolling Anti-Lag (17-18psi) 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 dynamically adjust settings in the tune depending on how much ethanol content is in the gas tank.   Keep in mind the Flex Fuel tune is all about convenience whereas a CustomROM tune dialed in for a specific ethanol % will offer the most precision and performance for that specific ethanol %
