ECU Re-Flash Tune File for:

4 into 1 Slip-On

with fxTuner's Monster Big Air

Version 2

High Performance ECU RE-Flash for the second generation Yamaha VMX17 V-Max equipped with a 4 into 1 Slip-On Exhaust System, fxTuner's Monster Big Air system, and a K&N Air Filter.  

This tune was developed to meet the fuel, throttle and ignition requirements of the VMX17 V-Max equipped with a VelociRaptor 4 into 1 Slip-On exhaust system, a fxTuner Monster Big Air system and a K&N Air Filter. The VelociRaptor system is no longer available, but this tune may be a near match for your 4 into 1 slip-on system. A "Slip-On" system utilizes the original stock front and rear primaries commonly referred to as "header pipes".  

Some of the Features:

• Rev Limit increased
• Speed limit removed
• Throttle By Wire restrictions removed
• Excessive timing retard eliminated
• Individual Cylinder's Alpha N and Speed Density Fuel Table re-tuned
• YCC-T Opening rate adjusted for better cruise response and maximum throttle angle adjusted for peak Horsepower

• Off-throttle engine braking in the first 3 gears has been reduced
• EXUP servo can be eliminated
• Air Induction System valve can be permanently switched closed
