Back in December my commute to work changed from about 15-20 minutes one way to one hour to an hour and fifteen minutes. This significant addition of mileage drove me (no pun intended) to make minor modifications to my vehicle and driving habits to improve my fuel economy. In the beginning I used my vehicle’s built-in Instant MPG data to adjust my coasting and acceleration.
This small move did show an improvement in fuel economy but the digital guage isn’t well placed for frequent checks. I decided to purchase something that was much more obvious as it could be mounted directly onto my dash.
I’ve been using an Auto Meter 9105 ecometer Fuel Consumption Gauge, which costs around $100, and connects directly to the OBD-II port of my vehicle. Not only does it present the data in a much easier format to quickly glance at but I’ve also discovered that the referesh of the data is much faster than that of the built-in guage.
I’d prefer that the display could be dimmed significantly but otherwise it’s nearly perfect. If I’m applying several basic hypermiling habits I can indeed improve fuel economy. My vehicle’s highest MPG rating (highway) is 29 MPG but I’ve been able to achieve 30.29 MPG once and most of the time I hit between 26 and 28 MPG unless I’ve had a lot of in-city driving in my car. I have more MPG data from this year that I may share in a later post.
The guage by itself does nothing to improve fuel economy but it provides the ability to make driving decisions quickly, potentially saving fuel.
Updated 04/18/2018: This device worked great the entire time that I used it. The only reason I stopped using it was because I unintentionally allowed the cable to slip behind the parking break, where it became crimped and shorted (fortunately this didn’t damage the car but I was lucky). But despite no longer having the device I’m left with a much better, innate sense of how to drive my vehicle more efficiently.
Sometimes it’s practical for the same person to setup multiple accounts on one machine for distinct purposes. While the fast user switching feature in OS X does make it easy to quickly move between accounts some people may find it more practical to be able to interact with the desktop of a different account while still logged into another one. If you’re this kind of person then you may find this post useful.
The method I’m using, which is based on information that I found in some forums, involves using Screen Sharing to connect to a different account on the same machine.
All of the necessary features are already built into OS X but unfortunately they won’t work in this scenario (by default). If one enables Screen Sharing, and then attempts to use the Screen Sharing app to connect to the local host, the screen sharing app will not connect and instead state that it cannot connect to the same computer. I’m not certain why this check is actually needed but it turns out that the check for enforcing this is not sophisticated.
It appears to only be checking for a connection to the local machine on port 5900 so changing the service to use a different port will work.
My wife recently purchased a new vehicle and so I started thinking about also purchasing a new vehicle. And then I decided that not having a car payment was something that I currently prefer over having a car payment (note – my wife had a very good reason to purchase a new vehicle, I do not).
Instead of purchasing a new vehicle I decided to add some enhancements to my current one. One of those enhancements is a Zubie Key.
The Zubie Key requires a subscription service that costs $99/year. The device works in conjunction with the Zubie Cloud service, which is used to review data via Web browser or from the Zubie App. When connected to a vehicle’s OBD-II port the device automatically connects to the Zubie Cloud via cellular connection. GPS is also built into the device.
