Reddit reviews Kitbest Bluetooth OBD2 Scanner Mini OBD Car Diagnostic Code Reader for Android & Windows, Check Engine Light Scan Reader. Supports Torque Pro & Lite, OBD Fusion, DashCommand

Yes - I bought a cheap $15 bluetooth ODB2 module that links to my phone. From there, I use Torque to manage everything. Great for testing sensors, checking codes, etc... Also cool to have it in my glovebox for when my coworkers need one out of the blue - makes you look cool for half a second.

EDIT: Here is what I use for the module:

As for the app, I use Torque Pro:

Bluetooth OBDII readers are ~$10 on Amazon!

Combine one with an app like torque- lite version that reads codes and does the basics is free, pro is like $5 and has bells and whistles.

This way, as opposed to simply reading the codes, you can get real-time data directly from your car's ecu.

Shits amazing for ~$20. What you save in repairs by catching issues before they turn into expensive problems is amazing.

Amazon, there are a ton that have fantastic reviews and are only around $15.

I ordered this one, its for Android only, but it does everything you need when paired with the Torque app.

Buy a $10 ODB2 scanner on Amazon, even if they've cleared the check engine light codes or disabled the light, the car will still report the codes and the failed tests.

My friend has this one and it seems to work well enough actually. I'm going to order one for myself right now. I have a magnetic phone mount that goes in my CD slot that works really well due to the layout in my car. I might use a spare phone to run as extra gauges and a music player. You could get a BlueDriver but those are about $100 though I hear they are really awesome. Though honestly for just $10 it can't hurt to at least try it out.

Edit: For $20 this one looks to be a bit nicer. I'm ordering one for myself right now. Thanks for reminding me. These are really handy tools and just plain fun to play around with.

This bluetooth based obd2 scanner (for $20) should work well with a phone app:
https://www.amazon.ca/dp/B01BY2CK32/. You'll probably find cheaper ones online as well.

You can. Get a Bluetooth OBD-II module from Amazon for about $10 and you can monitor your engine on your smartphone.

I just ordered one last week, along with a free app like Torque Lite and you can read and reset your light codes. Most auto parts stores will read it for you, but they aren't allowed to clear the code. I have found that a vast majority of my codes were caused by loose gas caps.

This is the one I have: https://www.amazon.com/gp/product/B01BY2CK32

This and the cheap Torque app will save you a few trips to the dealer in the future.

I bought one of these:
https://www.amazon.com/gp/product/B01BY2CK32/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

then using bluetooth, connected it to my android phone and I run the app called "DashCommand" http://www.palmerperformance.com/products/dashcommand/

That basic app will give dashboard, gauges, performance, but you need the PIDs for the Ford F150 for the 98 year. That's another $10.

Set up the misfire PIDs and run the datagrid while you are driving the truck. It'll show which cylinders are misfiring and how often they are misfiring.

Total cost was about $30 for me and it has more than paid back that cost in the information it gives me.

You can get something like this and use an app like Torque to find out what your engine is boosting to.

>All my LED's are done solid,

Solid? The problem with LEDs is that the computer expects a certain amount of draw and when the draw is low it thinks there is a bulb burned out and you typically get 'fast blink' and doesn't have anything to do with the connection being solid or not. The only way to fix this(properly) is to buy a flasher relay designed for LEDs and these don't work in every vehicle or install resistors(bad way) to bring the draw back up and defeating the purpose of LEDs. So called ODB safe LEDs just have a resistor added into the bulb which makes them very hot and prone to failure/melting lenses. In any case, LED bulbs will not create the problem you are seeing. You are on the right track with the battery sensing circuit. It lessens the life of batteries to overcharge them on a constant basis so newer cars will lower the charge voltage when the battery doesn't need the extra energy in order to extend their life. If you connected an ODB2 sensor, like this one, you will see that even though the battery/amp are only seeing 12v, the ODB2 system will still be seeing 14v(or whatever the alt is producing) and the voltage is being stepped down for battery charging purposes.

You could try a bluetooth OBD2 dongle. Then pair it to something like a Raspberry Pi inside which could connect to the OBD2, monitor data for engine on, and open the garage door if it's closed and the car is on.

I'd be curious to see what kind of lag there is in the cycle if it's going from a cold disconnect to garage door open, but it should be doable.

Not that I'd risk it myself, but I'm paranoid enough about CO that I've been pondering building an exhaust snorkel for my garage for during winter. =P

Also, the recommendations for an OBDII reader are absolutely on point. I have one like this.

It connects to my phone and I can gain all kinds of info about what my car is doing. Is your check engine light on?

FYI, this is the one that I bought, I'm sure it depends on the app that you use it with but so far it has served me well.

This scanner works great and only $10.99. The MyGreenVolt app gives lots of interesting stats.

Do you have a Bluetooth obd2 adapter ? Kitbest Bluetooth OBD OBD2 Scanner Adapter for Android, Car Diagnostic Check Engine Light Scan Tool Code Reader. 5 Year Warranty https://www.amazon.com/dp/B01BY2CK32/ref=cm_sw_r_cp_apa_i_Gls.AbD7XY9H9

Nope won't mess with warranty at all. It's bluetooth and pluggs into your obd port just those those snapshot things the insurance companies will give you for discounts. All torque does is monitor different sensors in the car, you may have to do a little googling to get all the PIDS set up correctly, but most work when you download them from the app. I think this is the one I have, never gave me any issues.

And then the Torque Pro (or torque) App is what I use for android. (not the exact same ob2, but based on the elm327).

Try cleaning your throttle body and run a can of Seafoam in a half tank of gas and see if that helps. Also you might get one of these Blue Tooth OBD2 readers that you can use with smartphone apps like Torque. You can check error codes and watch realtime data from many of the sensors on your engine.

I use Torque as well. You can find cheap small Bluetooth OBDII adapters on Amazon. They work great.

I bought one similar to this:
https://www.amazon.com/Kitbest-Bluetooth-Scanner-Adapter-Diagnostic/dp/B01BY2CK32/ref=mp_s_a_1_9?ie=UTF8&qid=1538833599&sr=8-9&pi=AC_SX236_SY340_FMwebp_QL65&keywords=odb2+bluetooth&dpPl=1&dpID=51z7L6z0ZfL&ref=plSrch

If you have an android phone, these are great. They pair to your phone and give code read out and ability to reset the light if its just a glitch. You have to have an app on your phone, some are free, but one of the best is only is $5.00 (torque pro). I'm not sure about iphone stuff. (edit: its also nice to have an idea what's wrong before going to a repair person.)

You have to buy the wifi version of obd2 scanner if you want to use it with iphone, but in most cases, you want to connect obd2 scanner with pc and check the engine data on pc, you do not need to buy wifi obd. For example, this one , only cost $9.99, much cheaper than wifi obd,but works great.

Eleven bucks, no real excuse.
