Actually, funny thing is the miles to empty doesn't work on normal 96-97 models lol. The PCM needs to have the fuel tank sender connected to it, and up to 97, they were connected directly to the cluster ... So a bit after I upgraded to a 2002 Express van PCM, I hooked my sender up to it. Thing is, I don't think the range computation is accurate at all, as on a full tank it shows 450 miles... Most I've ever been able to go on a single tank was like 340. I use the heck out of the "Fuel Utilization" display tho, as that's pretty accurate.
