Reddit reviews CREACLE V2.1 Super MINI ELM327 Bluetooth OBD/OBD2 ELM 327 Multi-Language 12Kinds Works ON Android Torque/PC

I'm from Romania so I've got it from a local store. The price is similar on Amazon : https://www.amazon.com/Version-Bluetooth-Multi-Language-12Kinds-Android/dp/B00N2K6M2A

For Linux a very good starting point is obdsim project.

Good luck with you project and keep us posted.

That's $80. You could buy 8 of the cheap bluetooth ones for that price.

I've bought 4 of them so far (for me, brothers and dad) and they're all going 2 years strong.

If you are on Android - test out the Torque App on Google Play before you buy Torque Pro just to make sure your bluetooth transmitter is compatible and you like the interface and all of that. When I was looking into a year or two ago, Torque was like THE highest rated and widely used app amongst performance car enthusiasts.

This is the OBD2 Bluetooth Adapter I bought a while ago and it works great with Torque - but there are dozens and dozens of choices for adapters.

I have owned 3 2.2s. They tend to run cold because they don't produce a ton of heat like larger displacement engines. If it's cold out it runs cold. If it is hot out and the mechanical fan is stuck on it runs normal temps. Also the dash gauge is not as accurate as the ECU temp readouts.

My guess is that you live in a cold environment and your mechanical thermostat is broken or old enough that it doesn't work right.

I currently have a built 2.2 turbo. When it is cold out, the gauge will read 150-185 when it is 30 or lower to 60 degrees. That is cruising on the highway at 50-70. Now I also use HPtuners to tune. I monitor my temps. Typically the loop from the heater core to the block will be within 180 to 195 where it is supposed to be.

My recommendations.

1. Buy the torque application for your phone. (7 dollars?) Then buy the 10 dollar amazon bluetooth obd2 port adapter. Monitor the temps the ecu can see. If the temperatures are from 180F to 199F your engine is running within range

2. Consider swapping the mechanical fan out for an electrical fan and temperature sensor relay. I have done this to every s10 I have owned. You gain 5-10hp (no joke). Better gas mileage and you can ensure your engine is running at the correct temps.
   
   
3. Temporary fix for winter. Take a cardboard box. Measure half the radiator size. Cut the cardboard box to half the radiator size. Then block off half the radiator. This will drastically help your temps. If you have a a/c, put the cutout cardboard in front of the ac condenser.

Sorry, first is Dash and second is Torque. Torque is by far the de-facto application for interfacing with OBD readers. Let's you create dials however you want and supports themeing to get it looking how you like.

My current reader is just a standard ELM327 reader http://www.amazon.com/Version-Bluetooth-Multi-Language-12Kinds-Android/dp/B00N2K6M2A/ That chipset comes in MANY readers so just find something that's available and priced decently and get it.

Yeah, I bought this one. Comes with a disc that has Torque Pro and DashCommand on it. I never could get DashCommand to work though. It wouldn't connect to the adapter and was only the trial version anyway.

$12 and it can scan codes, log, virtual dash, etc on both my 08 A4 and my wife's 08 Highlander via my kindle fire hd6.

If you want to go deeper, VCDS or the schwaben/foxwell scanners are the only readily options.

I'm not a mechanic, but:

If the CEL is on it has codes.
If the CEL is off it doesn't have codes, either because it is fine, or because the owner cleared them with a reader.

Get in the car and turn the key but don't start it, see if the CEL lights up, if it doesn't, they likely pulled the bulb because afaik, it should always light up when the key is in the on position but the car isn't started.

As for stores, you need to specify a location.
I personally use this one along with Torque and [DASH]

In the USA I believe Autozone does free scans, but they sell readers as well.

As the other poster mentioned - I'd get an ELM327 OBDII reader cheap, though you need an android device to use it. There are some that work over wi-fi for Apple devices, but the linked one below is bluetooth only.
I have this one, mated to a Nexus 7, and use the Torque app ($1.99, I think):

less than 15 for both ;) http://www.amazon.com/Version-Bluetooth-Multi-Language-12Kinds-Android/dp/B00N2K6M2A
