Which OBD vendor did you select?
Wanted to bring about the discussion of OBD2 bluetooth sensors and what brands or online retailer you selected for this. I havent researched much but my plan is to drop an Android tablet into the dash of my FR-S and use the OBD2 Tuner program for all relevant car statistics.
The most important stat which I am trying to achieve is miles before empty. From what I'm reading, people have had great success with a wide range of devices that differ in price from 20-200. I would love to see what other people purchased and how they are using their sensor. Are you leaving the sensor plugged in even when the vehicle is not on? |

I have a "Torque" program on my smart phone that gets a signal from the OBD2 port via an inexpensive bluetooth sender.
It works OK, however, I'm afraid to keep it plugged in all the time. Why? Because the sending unit has a little red light that stays ON even if the ignition is OFF. Why does that bother me? Because the government may be spying on me ..... humfrz |

it depends what you want it for. if you just want to see parameters on a screen, particularly ones that don't change often like temps, then any old bt obd2 device will work (even the cheap ripoff elm327's from ebay).
if you plan to watch something that changes rapidly (afr, boost, etc) and gain useful information or log from it, then the chinese clones are all but useless. really, any elm327 is as the minimum reliable polling rate for even a legit elm327 is 300ms, and the knock-offs often can't do even half of that. the best devices i've found for logging obd2 are the innovate ot-2 or tactrix cable, depending which software you plan to use. both are capable of speed more than adequate for logging. plx also makes a bt-compatible device that should provide useful data. |

Well the most important stat I want immediately is miles until empty. I want to then use that info to push to a new in-dash system. I would also like to not have to disconnect the sensor everytime I turn the vehicle off. Are my desires unrealistic? |

the in-dash system you plan to use will dictate what type of interface you need to buy. |

I am pretty sure any BT OBD device will be able to poll more than enough for a DTE calculation.

If you actually want to take logs and do work with it, a PC-based (or maybe Mac, but basically not a tablet) solution might be easiest. For universal OBD II use, I prefer the OBDWiz software with one of the compatible plug-ins. http://www.obdsoftware.net/obdwiz.aspx . Elmscan 5 is cheap and works well.
If you are going to put a tablet in there and look at it all the time--well you've got glare issues, and battery life issues, and all of that stuff. You have to put it somewhere. I think once the novelty wears off you won't find it that useful. If you just want distance to empty, use your phone. |

"The Kiwi 2 Wifi incorporates a new advanced power saving circuit, designed to shut off power to essential functions of the unit allowing the Kiwi 2 Wifi to be permanently installed in your vehicle without draining your vehicle's battery. After 5 minutes of inactivity, the Kiwi 2 Wifi automatically enters a low power sleep mode. To turn the unit back on, a simple press of the soft switch wakes the device back up." But the con is it seems you need to press a 'soft switch' to wake it up. At least the kiwi one. Others may have an auto wake on car start.
