I bought a Scanguage II for my 5.4 E350 and did about 1500 miles with is within the last week, mostly highway. I don't want this to turn in to another MPG thread, since Jage will disown me probably
, but do you guys who map your MPG with yours find it to be as accurate as the old gallons/miles at fill up equation? I got 14ish to 16.6 at best on my trip over 4 tanks of gas but the Scanguage never reflected this accurately. I haven't read the whole book yet, but followed the quick start method outlined in the user manual, and updated gallons and cost each fill up. Does it get more accurate over time as it maps your habits?
Also, I'm wondering if it will ALWAYS restart your average MPG every time you shut the engine off.
Also, I'm curious who has figured out the Xguage method of monitoring trans temp. I glanced over this somewhere but I'm curious if I need to add a trans temp sensor or something to make this work.
I know some of these questions may be answered in the manual, but my van, manual, and scanguage are many miles from me for a couple of weeks having my pop-top installed. I want to be prepared when I pick it up if I can.
