bootmod3 development team has worked tirelessly throughout the course of the past few months to deliver a new feature to its end users dubbed
bootmod3 CustomROM
CustomROM is a set of changes to the DME software which augment and enhance its functionality with features not provided from the factory.
...
bootmod3 CustomROM Features Overview
CustomROM Map Switching: Switch between up to 4 individual map slots On-The-Fly using a combination of steering wheel Cruise Control buttons
Press and HOLD RESUME buttonfor 3 seconds to activate MapSwitching mode, then use Cruise Control UP or DOWN buttons (1st position UP or DOWN) to toggle between slots
Alternate option to trigger map switching mode on B48/B58/S58 vehicles where Resume button does not work or is not present:
Press and HOLD Cruise Control DOWN button (2nd position DOWN)
CustomROM Flex Fuel: Dynamically adjust any of the Flex Fuel enabled Map Slots in their torque/load, ignition timing and fuel maps when tuning for alcohol based fuels.
Check Ethanol % content in dash on the RPM gauge by pressing the DOWN button (1st of the two DOWN position).
Example: 1000rpm = 10% ethanol, 5000rpm = 50% ethanol
CustomROM Rolling Anti-Lag: Build boost by using a combination of steering wheel Cruise Control buttons and pressing on the accelerator pedal for pre-configured insta-boost when roll racing
Press and hold the UP button (1st of the two UP positions for F series vehicles except B58, 2nd UP position on all others) and pressing the accelerator pedal to go WOT
Various tuneable settings and safeties available when custom tuning such as: Min Accel Pedal required, Max. Time in Antilag mode, Engine Speed, Min and Max Temperature thresholds for Oil, Exhaust Gas Temps and others in the bootmod3 Map Editor
CustomROM Live Adjust: When flashed on CustomROM various live adjustables are now available to help users adjust tuning parameters without re-flashing. Map Configuration screen so far has served the purpose of end-user configuration for any given map. Live Adjust screen takes Map Configuration a step further and applies changes to a running vehicle, without reflashing.
Adjust exhaust burble on the fly, no re-flashing
Ethanol Sensor Content % Override - Useful in cases where ethanol sensor may have become faulty. Without this convenient live adjustable the driver would be stuck with a car not starting on a high concentration of ethanol in the tank and a DME that doesn’t see ethanol content due to a faulty/disconnected Flex Fuel sensor.
4800+ tables available in the new Map Editor
Advanced Logging Updates: Various new as well as custom RAM datalogging channels to assist in tune review and custom tuning including over new/custom 80+ RAM channels
New RAM channels are definable if/when required by requesting it from the Map Editor
Flash Protocol Updates:
Last Flash Indicator on My Maps listing - Now stored with map on DME, does not require internet/server sync
Flash Counter Reset when re-flashing back to stock/re-lock for all MEVD DMEs
HPFP off during flashing to save battery life
bootmod3 CustomROM - Map Switching - 4 Integrated Map Slots
In its OEM form, the factory DME supports changes to Torque Request and Burble via the Driver Mode Selection switches (e.g. Efficient, Sport, SportPlus).

bootmod3 CustomROM Flex Fuel - Tuning for alcohol based fuels
| Info |
|---|
FLEX FUEL HARDWARE SETUP REQUIREMENTS Overview of the how the sensor data travels looks as follows: Flex Fuel sensor can be installed on the feed line as the factory S55 fuel system is return-less. If using the feed line, it is strongly recommended to use a splitter in the line where the sensor is installed to avoid introducing any fuel flow restrictions at higher power levels with higher fuel volume demand. |

bootmod3 CustomROM AntiLag
When racing or trying to achieve best acceleration times, the spool of a turbo impacts initial acceleration of the vehicle. The larger the turbo the more LAG (delay) before the turbo spools up and boost hits.

bootmod3 CustomROM LiveAdjust - Live Tuning Changes, no re-flashing
...
In the case of Ethanol Sensor or ECA board failure or disconnect, where users have a full tank of ethanol in the car, we’ve added the ability to override actual sensor value with a preset fixed ethanol sensor value so the car can be started and driven again. Some users may also override this value at important race events to avoid any chances of sensor cut-out/dying when racing when they’re sure of the ethanol content in the tank from the fill-up prior *** USE WITH CAUTION
LiveAdjust screen demonstrates some of the live changes we’re doing to actual calibration tables in the DME.
