Scangauge II stats going wonky in 2000 Dodge Caravan, Please help
 

Lately maybe due to not filling up and re-calibrating the SG2 much in the last several months the gauge started reading strange things in the "Tank" "Today" and "Previous Day" Meters; Sometimes I'll get readings like "17xx gallons used" and "$5,0xx cost" And see "2.3 MPG". Do you have any ideas why it's doing this? It also effected the Fill-up menu; I was going to calibrate the SG2 today when the van was filled up but I couldn't as the SG2 thought we went through 1,789 gallons or some high number since the last fill-up which isn't true; I calibrated it at the last fill-up.

Sounds glitchy. I'd contact the company - they're good at customer service:

Contact Us : Linear Logic - Home of the ScanGauge

Thanks for that suggestion, I used the contact us screen just a minute or so before editing this reply.

Here are some stats from the most recent wonky readings:

Current:

2.6 MPG
1382 Gallons
317 FWT Max
$4908 Cost
-2763 miles (Yes, Minus.)
C785 RPM Max (Yes, C as in Charlie.)
23.8 Hours
124 MPH Max
156 MPH Avg (?)

Today - Same as current

Previous day; Same as current except for:

2.7 MPG
1 MPH AVG

Tank: same as Current except:

0.0 Gallons to Empty
0.0 Miles to Empty

I realize it might be good to contact the company, I thought I'd leave this here for reference. Another note is that my Father occasionally drives the van down to the garage (He has his reasons), Anyway - The point is the van is sometimes turned on for less than a minute and then is turned off so perhaps this is messing with the SG2.

What is the version of your ScanGauge?

4.06

4.06? Linear Logic lists 4.02 as their most recent version. Perhaps you got a buggy beta version of the latest version?

Has that page been updated lately? I found 4.06 in Google:

I sent a few emails and will be checking for a response.

I had a response and the advice was to try resetting the ScanGauge II. I did that today and so far it seems to have helped at least, The "Tank" Screen operated well the last time I checked it. However, The "Previous Day" Screen was still off a bit.

Since I reset the SG2 it was working properly as of the last time I checked it, Though it isn't calibrated. The Tank, Today and Previous Day screens weren't showing "2.x MPG" and other odd things the last time I checked. Perhaps it'll stay that way for a while or perhaps not.
