Home and VRRV Chores/Upgrades

 Thursday, June 19

I noticed traffic picking up along FR 357 and decided to displace to home earlier by one day.

Lucky I did, there were several trucks and trailers inbound with OHVs/ATVs along with many campers!  The day use parking lot was full of offloaded trailers.  The Emancipation Federal Holiday had resulted in a "four day weekend" for a lot of people apparently.

I would see a two mile traffic backup that was heading into Divide as I was heading away from it.  Lots more RVs, OHV-laden trailers and just regular cars seeking to escape into the forest I imagine.

Good time to mention the formalization of Colorado Camping in Summer Protocol for me:  Camp only Sun-Thu, escaping back to home on the weekends when the crowds are out.

Thing One and I installed a 16ft propane hose extension on the VRRV.  This to hopefully eliminate the very slow propane leak I'd detected since returning from Europe.

RichardM, as always, helped me diagnose the issue.   The most common being the rubber hoses on RVs just aging and become porous.  Since my VRRV's hoses appear to be the originals, they're almost 20 years old!

I followed the path used by the stock lines.  The new line is secured at multiple point by double sets of zip ties, I may eventually use metal zip ties but I think it'll be OK for now.  The stock line components remain in place, just in case.  That's because I could not break loose the rear connector on the 5 ft portion!

After an abortive attempt to go cheap and use the Torque App to get a reading on the VRRV's TFT: Transmission Fluid Temperature, I had bought a ScanGauge II via Amazon.  Both RichardM and another friend, Dan K. use this product and are happy with it.

Yep, supposedly there's "plug-ins" for added functionality for the Torque app, perhaps including TFT but the website linked in the app is broken.


There is a newer model with a GUI (Graphical User Interface) but it was $110 more than the model II.  Me being a cheap bastard....I went with the II for $159.

Installation was easy, followed the setup instructions, watched Linear Logic's video, they're the ones who make this gadget.

As expected, I had to program in what they call a X-Gauge to report on Transmission Fluid Temperature or TFT.  It wasn't a big deal, just a couple of small hiccups.

1.  The default timeout for the ScanGauge is RPMs.  That is, it turns itself off if it detects 0 RPMS as in engine not running.  This timeout interval proved to short for me to enter the X-Gauge codes for TFT.  (The codes are available from scangauge.com).   

I set the timeout trigger to be COM, as in loss of power from the OBDII port.  That kept it on as along as the ignition key was in the ON position, engine not running.

2.  The second hiccup was inputting the correct X-Gauge codes for a 2006 Ford OBD system.  Mine uses the CANSF system.  The first one listed on the website didn't work, so I had to work my way down through to Method 3.  That one got a reading for TFT.  I was happy.  I will of course have to check it against actual temp via a touchless thermometer while the VRRV is running during stops to see how close it is.

Inputting the X-Gauge values, takes some initial practice, but otherwise easy.

Here's the displays I now can activate while driving:

TFT - Ambient Air
Intake Air Temp. - Average Fuel Economy

CYL: Cylinder Head Temp.

HPR: Horsepower

VLT: Battery Voltage

GPH: Gallons Per Hour

LOD: engine load

MPG: Miles Per Gallon

RPM, self-explanatory

You can have up to 25 custom X-Gauges!  Some of the stuff available I'm going to have to research as I don't know what it's really reporting.  For now, I have what I wanted.  Oh, and Engine Coolant Temp, which is a standard gauge.

Oh, and when your check engine light comes on, you can read the code and clear it as needed.  For instance, the VRRV occasionally pops a code for Fuel Rail Pressure Sensor.  I'll be replacing that soon.

In case you're wondering, the gadget below the ScanGauge is the TPMS monitor.

My thanks to RichardM for his help on the propane issue and suggesting the ScanGauge II.  Thanks for Dan K. for his input and info as well, he's got the III.
