Recommended Dyno Procedure - Edge Evolution 15051 Installation Instructions & Manual For Maintenance

Ford 4.6 and 5.4 Liter Evolution
"Non-stock condition detected. This is most likely because your vehicle has
been programmed with a competitive product. It is recommended that you
return your vehicle to a stock condition with the product that changed it.
Alternatively, you can plug your device into the internet update system and it
will load the necessary files onto your device to return your vehicle to stock."
If you don't have the competitive product that programmed your truck,
connect the device to Fusion where you'll be prompted to download the
correct stock files. Once downloaded, simply connect the device to your
vehicle, and the device will program the verified stock files to your vehicle.

Recommended Dyno Procedure

Using a dynamometer (dyno) to measure the power output of a vehicle is a
popular and very accurate method to check the performance gains achieved
when making modifications to a vehicle. Traditionally, you would select a
gear that would provide a 1:1 ratio through the transmission. This is usually
th rd
4 gear on a manual transmission or 3 gear on a 4 speed automatic
transmission. Using these gears provides the most accurate power rating
because the results are not affected by the torque multiplication which can
occur when using lower gears.

The F150, however, will not be able to run a full dyno run in 3 gear. The
wheel speeds generated are higher than most dynos will allow. The simple
nd
solution is to perform all dyno runs in 2 gear, although this method can
present problems due to the F150's torque management control system.
Torque management is nothing new. Manufacturers have been using it to
control rev limiters, speed limiters and traction control for many years. The
F150 also uses torque management to control the actual rate of acceleration
of the vehicle. There is also torque management present when the
st nd
transmission is placed in 1 and 2 gears. The torque management can cause
erratic and inaccurate dyno results. Because of the torque management, it is
moderately difficult to achieve accurate results from dyno runs.
Currently, the most consistent and accurate method of performing dyno runs
is as follows:
