Have a ’08, 5.4 screw with tow package. Will be towing a boat quite a bit – not heavy enough for any concern. However, I’m that guy – I just wanna know.

Just purchased/installed the Edge Evolution and have two simple questions.

1)Besides monitoring the trans temp, what else should I monitor when towing? Really don’t need MPH (have GPS). RPM – have the gauge unless the digital is better.

2)Along with #1, what parameters should I expect? What parameters are ok? When should I worry?

Here is the list I can choose from:
RPM
MPH
Engine coolant temp
Engine oil temp
Trans fluid temp – already monitoring this
Cylinder head temp
Intake air temp
Line pressure desired (trans main line pressure)
Actual fuel rail pressure
Output shaft speed (OSS) - Used with TSS to determine if trans slip is occurring
Turbine shaft speed (TSS) - Used with OSS to determine if trans slip is occurring
Mass air flow
Mass air flow voltage
Variable cam timing
Spark advance
Torque control
Engine load %
Accelerator pedal position
Battery voltage
Instant miles per gallon
Average miles per gallon
Current Gear

Appreciate your responses…..

 

I monitor the tranny, engine coolant, air intake temps along with the average mpg. Some prefer the cylinder head and oil temps but I feel what I am looking at gives me a good overall picture especially when towing which I do often.

 

Which edge product did you buy? I installed my edge evolution CTS 2 days ago. The edge 85250. For ford f 150 2004-2008. Gas. My list of displays are missing around 5 different types of settings. Average mpg is one of them. I only have instant mpg. Is your a 85250 edge for gas 2004-2008?

I have a2007 FX4 5.4

 

I have the Edge Evolution - 15051 (gas). It's for the 2004-2008 F150.

 

When towing I monitor:
Comm gear.
CHT
TFT
Engine load.
I also pay attention to the rpms on the dash. If they start bouncing around and the tft goes up along with the comm gear display switching, its time to slow down.
