Rep Power: 0 How to read the speed?
Hi Everyone,
I am wondering if it's possible to read more info like the speed, rpm, amount of gas left in tank, etc..from OBD-II port? if not, is there another computer port on a Honda Civic 2009 that gives me those readings? I think there are some aftermarket spedometers that mount on the dash, etc....so I am wondering how they read the speed and other info. Thanks.
Thanks,

If you think a good mechanic is expensive, try hiring a bad one

The aftermarket toys just use available data to display what they want and how they want it, usually only from the PCM data.
It's all just a matter of what the aftermarket toymakers have enabled or have paid for access to. I doubt any of them ever let you have the amount of data that is available to a real scantool.

My HDS displays FAR more than the 26 pids that this toy gives you. All at the same time.
I kinda wish I could get some of the engine data and some other stuff to display on the IMID in my 12 Civic.

I would suggest the Scangauge II, they cost around $170 new but you can find them used cheaper. This plugs into the OBDII port and gives you all kinds of info like that and also fuel economy data. I've owned one for 2 years now and love it.

I own an Ultragauge, it will do all of that and more. Runs about $70. Plugs into your OBDII port and you can mount it on the dash or on the window. I have mine mounted off the the right a little in from of my instrument cluster. Like this:
