ANNUNCIA TOR OUTPUT ON Select this to activate the annunciator output function once again after you have you disabled it as described below When the gauge first powers up it will indicate the status of the annunciator on or off ANNUNCIA TOR OUTPUT OFF Select this to disable the annunciator output function HORSEPOWER ADJUSTMENT This choice allows you to enter a correction factor for the horsepower parameter and the MPG parameter This one correction factor applies to both These parameters are available on those cars using a factory Mass Air Flow sensor Net horsepower and fuel mileage can be closely calculated by knowing the mass air flow value However since each car is slightly different in efficiency this calculation can be adjusted if the exact peak hp is known after being run on a dyno or the MPG reading needs adjustment For example if the gauge indicates 300 hp and the net hp not rear wheel hp is determined to be 315 you can enter a correction factor of 1 05 adding 5 This is done by selecting this menu option and entering this factor There is no decimal shown so you will be entering this value as a three digit number For example 1 05 will be entered as 105 0 95 will be entered as 095 subtracting 5 Likewise if fuel mileage reading is known to be off by 5 say the gauge is reading 5 low enter a correction the same way 105 As with the shift light entry field you will use the left button to chan2.
