I'm looking for a obd2 adaptor that I can plug my iPhone into that can monitor oil and transmission temps when towing. Has anyone used something like this?
Okay, so I have a Galaxy S7 (favorite feature is wireless charging) and have decided to get a wireless OBDII code reader but when I look up "ELM327" on eBay I get many different ones, brands, colors, sizes. Which one is preferable?
Can you read the ATF temperature with your new device?Coming to this thread late. Got a little board sitting around and a New 2017 Rav4 Lim. sitting in the garage and looking for a new toy to play with. found the OBD 2 scanners on Amazon and got to looking into what they could do and the apps would support them. Now the dealer set up the Rav4 for me as to all the options (turn / lane signal flashes and door locks, etc.) so didn't need that function (save a lot of $$ on that). I have Apple hardware (iPhone and iPad Pro) so was cautious about Bluetooth. The WiFi OBD2 connections were much cheaper. After reading the customers reviews I chose the Veepeak Mini WiFi OBD2 Scanner Adapter for iOS and Android, Car Check Engine Light Diagnostic Code Reader Scan Tool for Year 1996 and Newer Vehicle in the US (less than $20) and then went to the App Store and downloaded "DashCommand" ($10) Setup was easy, just follow the instructions, and a little looking at their website (DashXL.net) found some great dashboards. (Im using the 4Rummer dash, just search for it) Don't have a PC anymore so can't download the editor and create my own. So for less than $30 I now have a new toy to play with.
PS: check if your OBD2 adaptor should be left plugged in. Some will drain your battery. The more expensive unites can be left plugged in with out this happening. Check!
