Here's another iPhone application that demonstrates that soon there is nothing you won't be able to know if you have just one device. DevToaster has created an app called Rev that reads information straight from the OBD-II port on your car and displays it on your iPhone. When it's fully operational, Rev can display things like vehicle speed, RPM, fuel consumption, calculated engine load, and a host of other parameters. You'll even be able to check and reset engine and error codes.

The only hitch is that you need an OBD-II/WLAN interface that can beam the information from the port to the phone. DevToaster is working on that now; in the meantime, you can download Rev Lite at their site and we have a feeling California's going to work on more phone-centric activities to ban.

      cool... but the wifi adapter is sold by one company, and from the looks of it costs 260 euros. Thats quite a bit...

      There's also a freebie version that does stuff like acceleration, etc without reading the OBD.

      I remember seeing an ODBII to Bluetooth adapter... I wonder if that would work in place of WiFi?
        • 6 Years Ago
        It might work, but it also might interrupt hands-free appliances, which are necessary to use a phone in the car. No hands-free, don't use the phone in the car.

        Wifi and Bluetooth can co-habitate. I hope the adapter is read-only, and is securely paired to a single iPhone/iPod touch, not just broadcasting to any wifi listener.

        I have the free lite version, but I haven't yet put it through it's paces. It does have an accelerometer monitor in it.

        There is not bluetooth access as part of the iPhone APIs. So, while it would be cool, currently not available.

      My Pontiac GTO can show all of this mentioned above (and more), just by holding down the Mode and Set buttons on the dash when you start the car. It's a pretty cool feature I just found out about the other day. And you don't even need a special tool (like an iphone and software) to see the information. It shows all the car data in the trip computer.

      "So what are you waiting in line for?"

      "I'm getting the new iPod in limited edition burnt umber. How about you?"

      "I'm getting my car's ECU reflashed."

      "What?"

      "Yeah. iPhone crashed. Took the whole thing down with it."

      "Did you try holding down command-opt.-esc?"

      "Yeah, right after I tried rebooting off the OSX DVD in my sound system (sigh)..."

        right. cause I've been running a program I made off of winmo (with no probs) before the iphone came out. Please try again.
        • 6 Years Ago
        Andrew...I've had WinMo and iPhone. My iPhone has actually been far less reliable. The iPhone just makes up for the annoyance with features.
        • 6 Years Ago
        Sorry, you're thinking of a Windows Mobile device :D
      • 6 Years Ago

      it is BS that WinMo has been around for a loooong time but there are no cheap OBDII apps....then the iPhone comes along and there are like 50.
      • 6 Years Ago
      Why would you want to display vehicle speed or RPM's? That is what the dashboard is for. Other stuff like oil & coolant temps are more useful since they aren't displayed on most cars.

      While it is crappy to have to pay for most of these iPhone apps, there are some neat ones out there and it is nice that they are all consolidated thru Apple's store. But there are tons of WinMo apps (& MODS!) for free that people cook up. If anyone knows of any automotive-related apps for Windows Mobile please let me know!
