I just ordered a Edge Color Touch screen display for my E-450 based van.
With this display, I will be able to read 8 items at once. This will include transmission temp, RPM, and perhaps coolant temp, voltage, ect.
It will allow you to change the tire size, and recalibrate the speedometer.
I was most interested in the RPM and transmission temps. IF I am running really warm on the transmission, I will install a larger cooler. I should be able to tell the oil pressure much better. And I can reset the engine codes too.
I bought the Edge CTS from Amazon.com for $310. I had seen them other places for as much as $550, and on sale for $399 at one place.
Good luck,
Fred.
