Using an OBD-II Splitter to Connect Two Devices (Fuel Economy Guage & Zubie)


I’ve added a couple of posts about the fuel economy guage recently but in those posts I left out the fact that I already had one device on the ODB-II port of my 2008 Chevrolet Impala – a Zubie vehicle monitoring device that is cloud-connected via its own celluar connection (the one at this link is slightly different from the ones that we have; they are both white and were also purchased as a two-pack – I don’t know if there is any technical difference between the models).

In order to solve this issue I decided to purchase a iKKEGOL 30cm/12″ ODB2 ODB II Splitter Extension Y J1962 16 Pin Cable Male to Dual Female Cord Adapter. I’m not sure why the item name is written as ODB2 ODB II as it should instead be OBD2 OBD II but it does work properly. I read several reviews before deciding to purchase this devices as I was uncertain whether or not having two devices connected in this way would cause issues. I decided that it was not very likely to be a problem because the fuel economy guage only reads from the system and the Zubie device probably rarely ever sends data, if at all.

I haven’t had a single problem with either device since I connected them to the splitter.


The white fabric is actually an elastic material helping to ensure that the connection to the OBD-II port doesn’t slip loose. Normally, the cables are tucked away better but I had just shifted them before taking this cable to reposition the fuel economy guage.

Update 04/18/2018: Using the splitter with these devices worked great and didn’t seem to cause any problems with my vehicle. 

Using an Auto Meter 9105 Ecometer to Improve Fuel Economy of a 2008 Chevy Impala



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. 

Using a Zubie Key (Vehicle Monitoring Service)


ZubieMy 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.

GL1 OBD-II to iPhone/iPad/iPod touch


For several years I’ve been somewhat interested in having the ability to read automotive diagnostic information. It’s probably a very basic geek concept – my car has a computer so I want to be able to access the data. It also comes from not wanting to rely on a shop to interpret the engine code results.

I’ve found that dealing with mechanics and auto parts store employees is a grab-bag of experiences and most of them have been negative or at least unimpressive. Actually, since I’ve became I homeowner I’ve found this to be true with many service industries – the bad ones are really bad and the good ones are really good. There doesn’t seem to be much middle ground.
