R3 / MT03 ECU Flash

Decel Fuel Cut
[ DISABLE ]
- Disables fuel injector deceleration cut-off. This helps smooth reaction when you let off the throttle reducing abrupt engine braking, also sends unburnt fuel to the exhaust causing some backfiring when decelerating from high RPM. This can be corrected with exhaust valve block off plates, but most people like it!


Cooling Fan ON Temperature
[ 180F (82.2C) ]
- Fan temperature is modified to turn the fan(s) on at a lower temperature (selectable) OEM is 212F. We recommend 170 to 180F.

AIS Valve 

[ DISABLE ]
- Disables the secondary Air Injection System (AIS) routes fresh air from the airbox to the exhaust system in order to aid the combustion of unburned fuel in the exhaust.
