Once you have activated your BM3 license and purchased a custom tune from us you will need to request a custom tune within the BM3 app.

Here's how:

Within the Bootmod3 app you will go to your "My Maps" screen and click the button at the top "Request Custom", then choose  "Paul Johnson Tunes".   In the description/comments list your mods, fuel(tested eth% etc), and goals for the tune.

Once we receive your payment and your BM3 tune request Paul will prepare the base map for you to flash. 

Once the base map is flashed to the vehicle you will datalog the car.  Paul will review the logs and make the necessary revisions to the tune based on the logs.

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. 

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.

To read about these new CustomROM features available on the S55 engine refer to this document.

Custom tuning for S55 is available for pump gas, race gas, full E85 and E85 blends, as well as WMI.  Results will vary depending on the fuel used. 

We also offer road course specific tune calibrations where linear power delivery, smooth pedal sensitivity and torque management are dialed in so that you can exit the corners as smoothy as possible.
