Nitrous Express Maximizer 4 - Manual (Page 7)

RPM Cutoff allows you to set the upper RPM threshold above which the nitrous will be turned off. If
you remove the check mark the nitrous will not turn off at the cutoff.
RPM Trigger allows you to set the minimum RPM required before the Nitrous can be triggered.
3.5 Ramp Set-up
The software allows you to drag and drop any dot on the ramp between 0-100%. The controller will
extrapolate between the dots thus creating a nitrous curve instead of the traditional ramp. We have
provided some additional tools to help smooth the overall curve, which we discuss in the following
sections.
Reset to Straight Line allows you to set the curve to a straight line between the Start and Final
targets.
Smooth Points will apply a smoothing algorithm to your curve. This button can be pressed multiple
times until the desired curve is achieved
Undo is an undo button. If you applied the smooth points feature or dragged a dot, this feature will
undo the change. It has multiple levels so you can undo several changes
3.6 Upload / Download Configuration
DO NOT connect the controller to your PC until you have installed the software.
Before programming the MAXIMIZER-4, it must first be installed in your vehicle because it requires
12-volt power. To connect the MAXIMIZER-4 to your PC, use the USB cable supplied in the box. Plug
the USB cable into the MAXIMIZER-4 and into an available port on your PC. Clicking on the “Find
Controller” button will connect the PC software to the MAXIMIZER-4. Now you can either manually
enter the configuration settings that you want in the MAX-4 or you can upload a previously saved
Configuration file from your PC into the MAX-4. Once you have entered or uploaded the desired
settings the changes will be effective immediately however, you will need to click the “Save Data to
Controller” button to permanently save the settings in the controller. If you exit the software before
clicking the Save Data to Controller button, the changes will not be saved. Clicking File, then Save
(or the Save button) will save a configuration file on your PC.
7 Final Testing
1) Disconnect the solenoids from the MAX-4 to prevent them from firing. On a new install we
recommend that you connect a temporary light in place of the solenoids and make a test run to
verify that the solenoids will be active only when desired.
2) Turn on the ignition power and start the engine.
3) Verify that the engine rpm displayed in the MAX-4 software matches your tachometer
4) Verify that the TPS percentage reads 0% with the accelerator pedal in the idle position and 100%
with the accelerator pedal in the Wide Open Throttle position.
5) If using the VSS input, drive the vehicle and verify that the speed displayed matches the vehicle
speedometer.
6) If using the MAP input, drive the vehicle and verify that the MAP displayed matches the vehicles
boost gauge.
7) If using the Lambda / ARF input, drive the vehicle and verify that the Lambda / AFR displayed
matches your wide bands display and that the AFR displayed seems reasonable for whatever
condition the engine is currently running.
8) Arm the MAX-4 and verify that the LED on the MAX-4 is illuminated when armed.
9) Once proper operation is confirmed, you can remove the temporary light, reconnect the
solenoids and go have fun.
