• Torque limits for L raised to 100%, reverse raised to 75%
• Component protection mode for fueling lowered to increase torque and horsepower, especially right after the pedal is floored.
• Ignition timing per cylinder is optimized for maximum power as well as drive-ability, careful consideration was used not only for when at wide open throttle, but as well as cruise, throttle transitions, ect.
• Throttle feel and control is thoughtfully improved, to control through a whoop section, on/off feel in short course style racing or playing in the woods, eco mode is improved but offers the less aggressive pedal for technical rock sections or simply loading on a trailer.
• Speed limits removed, your speed limit is your rev limiter/gear
• Rev limiter raised to 9200 RPM
• Rough road detection is raised to max to prevent power loss
• Plus more!
