User Manual

Ford 4.6 and 5.4 Liter Evolution

• AFRP (actual fuel rail pressure) – Used to control the flow of fuel

while an injector has been opened.

• OSS (output shaft speed) – Used with TSS to determine if transmission

slip is occurring. If OSS = TSS, no slip is occurring.

• TSS (turbine shaft speed) – Used with OSS to determine if

transmission slip is occurring. If TSS = OSS, no slip is occurring.

• MAF (mass air flow) – Used to determine air/fuel ratio. The value

displayed is divided by 100. (Example: 5.4 displayed = 540 g/s)

• MAFV (mass air flow voltage) – A voltage representation of MAF

(from sensor).

• VCAM (variable cam timing) – Number of degrees the cam is

advanced/retarded in regard to crankshaft angle.

• SPARK (spark advance) – Current timing advance/retard for the spark

plugs.

• TQC (torque control) – Amount of torque reduction to control traction.

• LOAD (engine load %) – Percentage of total power available being

used by the engine.

• APP (accelerator pedal position)

• BAT (battery voltage)

• IMPG (instant miles per gallon) – MPG of your vehicle at that instant

without average that value with past MPG

• AMPG (average miles per gallon) – This is an average of the MPG

over a long period of time.

Diagnostics

The Evolution is also a powerful diagnostics tool. You can view any

diagnostic trouble codes (DTCs) your vehicle may have, which in turn allows

you to fix them. It will also allow you to turn off that annoying “Check

Engine” light when the problem has been addressed (no more expensive trips

to the dealer for a diagnostics scan).
