Note: It is recommended that you perform this on a test track or dynometer
1) Disconnect the solenoids from the relays to prevent them from firing.
2) Start the car and arm the MAXIMIZER-3.
3) With the engine idling, press and hold the TPS learn button until the RED, YELLOW and
GREEN LEDs begin to flash. DO NOT change the throttle position until the GREEN LED stops
flashing and goes out. If the GREEN LED begins to flash quickly, you have a bad TPS signal.
Note: For drive-by-wire it is recommended that you use the falling TPS signal
4) Once the GREEN LED is out, open the throttle all the way while driving the car and then
release it. Repeat this step twice. If the GREEN LED is flashing quickly after this procedure the
controller did not learn the TPS correctly. Power off the controller and start again.
5) If step 4 completed successfully, verify that the GREEN LED goes off at IDLE and on at WOT.

The following steps assume that you have completed the software install and have uploaded your
configuration successfully.
1)
Disconnect the solenoids from the MAXIMIZER-3 to prevent them from firing.
2)
Turn on the ignition power and start the engine.
3) Arm
the
MAXIMIZER-3.
4)
Verify that the RED / YELLOW / GREEN LEDs are off with the throttle in the idle position.
5)
Slowly increase the throttle until you reach the Turn On At RPM setting that you downloaded
for stage 1.
6)
Watch the YELLOW LED. If you set the correct RPM multiplier it will come on just as you
reach the target RPM.
7)
Now repeat steps 5 and 6 and watch the RED LED and use the Turn On At RPM setting that
you downloaded for stage 2.
8)
If the LEDs come on at the right RPM, then you selected the correct multiplier.
9)
If the LEDs come on too late then the RPM multiplier is too high and you need to set the
multiplier to ½ the previous setting and repeat the RPM set-up verification.
10) If the LEDs come on too soon then the RPM multiplier is too low and you need to set the
multiplier to 2x the previous setting and repeat the RPM set-up verification.
Note: DO NOT use the half-step multipliers unless this is a 3 or 10 cylinder application.
The installation is complete!

The Nitrous Express MAXIMIZER-3 introduces the first traction controlled progressive nitrous
controller. This progressive controller can be configured to accept commands from the Davis
Technologies module allowing it to scale back your nitrous ramp. The MAXIMIZER-3 will run its
profile normally, but if the traction control module detects tire spin, it will instruct the MAXIMIZER-3 to
reduce the ramp. How much and how long the ramp is reduced is set by the configuration in the
