ADJUSTING TUNES
Each tune has a variety of settings that can be adjusted to customize how the engine handles. Not
all tunes will need to be changed for all riders and riding styles. The MSD Blaster FI will prescribe
parameters exactly as they are entered by the user. The unit will not protect the engine from damage
if setting parameters are made outside of safe operating range.
SETTINGS
In this tab users can put in the basic parameters for the engine.
Engine Speed Limit - This is the overrev limit and is always active in order to help protect the engine from
damage. The engine will not be allowed to go faster than this setting at any time.
Vehicle Speed Limit - This is the maximum speed (mile per hour) the vehicle will go. When the ECU
sees the given speed a rev limiter will be activated even if it is below the Engine
Speed Limit.
Decel Fuel Cutoff - This setting allows the user to automatically shut off the fuel during deceleration.
Doing so can help with fuel efficiency, depending on driving habits. The user
defines the lowest rpm at which the fuel should be cut off. There are a number
of other parameters, such as engine temperature that cannot be controlled by
the user. After all parameters are met, the fuel will be shut off when the throttle
position is fully closed and the engine is reving over the set speed.
