Fuel Economy instrumentation - do you use it?

[krousdb]

I have a Magellen Explorist 400. Most GPS's have elevation. You can find the Explorist on ebay for under $100.

I don't have any FE installed yet. I do have a used Apexi Vafc which allows 8 or 16pt fuel adjustment +- (its the old Vaft, precursor to the NEO which is approx $400). i'd like to connect the Vafc and a good AFR gauge (on another thread). hmm i think a seperate toy- apexi auto timer has battery voltage readout on it come to think of it. How does a Vacuum gage or Voltmeter help with fuel efficiency?

I don't currently use FE instrumentation but I do use a GPS to calculate my miles, max speed, ave moving speed, time stopped. I'm still new to hymermilling (3 tanks) but my last one was 37MPG which means ((37-28)/28)*100 = 32% I think I'll get a vacuum gauge.

(I realize this is an old topic but thought I should reply anyway since I voted "Yes".)

I do have a Scangauge II V 4.06, And it has been of help and I can still learn more by using it. However, The gauge has gone wonky lately (And it might be due to starting the car and turning it off quickly) and hasn't always shown proper tank data in the 2000 Dodge Caravan 3.0 Litre model; Sometimes the tank data reads something like 2.3, 2.6 or 2.7 MPG, 4,000+ miles and something like a maximum speed of 124 MPH but an average of 154. Perhaps I should reset it to the factory defaults?
