2008 F250 V10 question

I think the SCANGAUGE would be my choice as it can be programmed to do several functions. I love mine on the V10.

Thanks I will check into that

If you have a smart phone you can get an adapter (bluetooth or WiFi dongle) with that and an appropriate app this will give you everything the scangauge gives you and then some. I am using an Iphone 4 with the Dash Command APP and a WiFi dongle.

:S I just cannot seem to keep up. What is a dongle?

A dongle is a small electronic item that plugs into a port.

I also recommend a Scangauge 2. They are very useful devices in so many ways.

Edge Insight CTS (color touch screen). More expensive, but more versatile and expandable.

Thought all F250 V10s had gauges plus a tachometer. My 2002 and 2008 had gauges, including tranny temp.

They have what a lot of people refer to as "idiot gauges". They don't actually indicate pressures and temperatures. Instead a limit switch and the computer just directs the needle to point into a reasonable range unless there is a problem.

It's not just Ford doing this. My GMC has an oil pressure switch. The computer calculates what pressure the "gauge" should indicate. If it drops below about 7psi the needle drops immediately to zero.

Oil pressure in the Fords is a simple switch.

The engine and transmission temperatures do get a sender signal, but the PCM buffers the signal so it doesn't fluctuate within the normal range.

My 07 Cummins had some real gauges, some buffered. Engine coolant temp was dead accurate until a certain level, then, even as the actual temp continued to climb, the needle didn't. Then, once it reached another threshold, the needle would move 20% up in 1 second, then back to being accurate again. Oil pressure was also buffered. Its common. The scangauge I had gave the real/actual numbers.
