How to Test a Titan Dyno
Dyno tests are performed on a variety of different vehicles to determine performance information about the engines. Nissan Titans are powerful pick-up trucks that are used for towing and pulling. Testing the Titan dyno will help you understand the torque, horsepower and exhaust temperatures for your truck, which will allow you to modify the vehicle to increase engine performance.

1
Complete a preliminary evaluation of the Nissan Titan to make sure that there are no leaks and that all of the fluid levels and tire pressures are right.
-
2
Back up the Titan so so that the rear wheels are perpendicular between the two rollers of the dynamometer. Back up as straight as possible to guarantee an accurate and safe reading.

3
Select the "Down" option from the "Safety" menu of the dynamometer. This will drop the rollers. Once the rollers have dropped, put the Titan in "drive", and ease off the brake. This will make the wheels spin slightly until the truck is centered on the rollers of the dynamometer. Put the truck back in "park" and turn off the engine.

Prepare the Titan for the test by strapping it securely to the dynamometer, using the meter's straps. Attach the strap on each side of the dynamometer to the truck frame or tow hook on the opposite side of the truck, so the straps cross each other, providing extra security. Crank each strap to tighten it until the truck will not move on the dynamometer, but not so tight that there is tension. Attach the front strap to the front of the frame and crank it until it is secure. Place wheel shocks on the two front tires and secure them to the floor to protect them during testing. Place the exhaust hose over the exhaust pipe so the testing area does not fill with exhaust. Put a large fan in front of the car's radiator and turn it on, to prevent overheating during testing.

Attach all the gauges and cables to the inside of the truck. Place a strip of magnetic silver-lined tape on the accurate pulley and mount the optical sensor next to it, so the eye of the sensor is facing the tape. Clip the spark-plug meter to the spark plug.
-
6
Start the truck. Select "Calibration" from the dynamometer menu, then select "Dyno Parameters." This will open a new window with information about each test you can conduct with the dynamometer. Calibrate the RPM meter by selecting 2500 RPM from this menu, then switch the car into "drive" and bring up the RPM gauge on the car until it reaches 2500 RPM, then select "OK" on the dynamometer. This calibrates the dynamometer for your Titan.

Select "Test" from the dynamometer menu, then select "Performance." Choose the test that you would like to perform on the Titan. There are many tests that can give you torque, horsepower and power-curve figures. Input the information to complete the test, including the weight of the car and the start-stop speed. The start-stop speed can be any figure, but testing at 60 to 80 mph is generally a good window for testing.
-
8
Select "Start Test," then begin to accelerate the car until you achieve the start-stop speed that you outlined in the test parameters.
-
9
Repeat this process with all the dynamometer test options that you desire.
