97-98' EDGE and Gryphon problems?

[Jackpine]

Nice questions, and I don't have all the answers.

But, as to Tire Size. the 97 and 98 trucks did not have PCM controlled speedometers, so the Edge/Gryphon cannot adjust the readout. You have to replace the VSS (in the rear axle I think) to adjust for non-OEM tires and/or gears.

There's really no other problems though. The older platforms don't have some of the information displays that the newer units do, so that might be what your friend is talking about. Times change, and we're talking technology that is now 11-12 years old? You'd probably send a computer that old to the landfill. But, if it's in your truck, maybe not, since the truck still runs.

Heck, my "daily drive" is a 19-year old Honda Accord (don't throw rocks). It runs great (and looks pretty good too, since I've taken care of it).
