  1. Tracking kWh Use using OBDII

    Chevy Volt General Discussion, News, and Events
    I recently started to track my kWh’s used to charge my 2016 Volt. I have an iPhone, so I use "OBD-Fusion" which is similar to Torque for Android. Here are a few screenshots. Wh Last Charge refreshes only after removing the charging cable. I usually take a screen shot in the morning before I...
  2. MyGreenVolt OBDII help?

    Generation 1 Volt (2011-2015)
    So what a great app! Get on it if you haven't already. My only trouble is I receive no data to the app even though my OBDII is connected to the phone and the app. Just wondering if anyone else has had success with this OBDII reader or has any advice:? Thank you!
  3. Gen1 Volt: Behind the scenes - Radio + ECU Software Update

    Generation 1 Volt (2011-2015)
    MODERATORS: Please move if there's a better place, or notify if it should be a new thread and I'll re-post it. I lightly documented the software update process for the Gen1 Volt while I had it in the shop today to receive 1.) Radio updates and 2.) an ECU update. I took multiple photo's of the...
  4. Is there a recommended inexpensive OBDII reader and iPhone app combo for error codes?

    Generation 1 Volt (2011-2015)
    Hi all, I have had the engine light come on a couple times intermittently. I'd like to read the code and roughly know what is wrong. I currently have an ELM 327 OBDII reader that transmits via wi-fi to my iPhone where I have the Piston app. I want to make sure I plug the reader in in the...
  5. DashCam / OBDII Combo

    Generation 2 Volt (2016-2020)
    A small dashcam startup, Waylens, has a camera that records a lot more than just video via a BluTooth connection to OBDII reader, which can then overlay a number of car stats in real time. Does anyone have a good idea if this will be compatible with Gen2...
  6. Chevy Volt vs Cadillac ELR - why not make your Chevy a Caddy?

    Software & Programming/Code - Chevy Volt
    So why haven't I heard about anyone reprogramming their Volt with ELR values? Software programs such as EFILive or HPTuners support the ECM (engine control module) but not necessarily all the hybrid parameters. HOWEVER, a GM MDI and GDS2 subscription would allow someone to program in the VIN of...

  8. Maximizing State Of Charge (SOC)

    Generation 1 Volt (2011-2015)
    There has been a technique that has been used by some here instead of using remote start. Instead, we would turn on the car with it still plugged in (L2) and the car would continue to charge for 15-20 min or so. Make sure all accessories are off (lights, climate control, radio, etc). One...
  9. OBDII Y-Cable

    Software & Programming/Code - Chevy Volt
    As we don't have OnStar in OZ, would it be possible to use an OBDII Y-Cable to connect both of these devices to work simultaneously? (1) The OVMS project for the Volt/Ampera (Similar functionality to OnStar app) :cool:
