TPS threshold value.
Under TPS, press the Up or Down Arrow to toggle the TPS mode ON or OFF.
Move the cursor right to the 200 setting, then use the Up and Down Arrows to select the trigger level. This
number is set to near 200 at the factory. You can adjust it from 50 to 248. To choose your level, look at the
third Stats screen. (Press “SEL” to get to the Main Menu, then select Stats, and press “SEL” until the third
Stats screen appears – “N2O” is displayed in upper left-hand corner). With the engine on a test stand,
quickly press the throttle fully and release it. Note the number under “MxTP” This is the maximum value
your TPS will output. Let the engine idle, clear the Stats screen, and note the MxTP number, which is the
minimum TPS output. Choose a number close to the maximum for full-throttle activation. If you choose a
number too close to the maximum, it may sometimes fail to trigger. If you choose a number too low, it may
trigger when only moderate acceleration is desired.
Press the “SEL” button to return to the Main Menu.
