It was recommended that I take a look at the OBDLink LX but they are only compatable with Android and I have an Iphone. The MX Wifi Model is a bit out of budget. Does anyone have any other OBD2 readers they would recommend that would work with an Iphone?
In order to use a smartphone, you first need to get a reliable (and fast) OBDII dongle. To get a good one, you have to spend the money. Have a look on the EngineLink app (it's an iOS app) website, I believe they recommend dongles that work well with their app. Good luck in your quest.
I have this one, which is a cheap ELM327 knock-off. It was affordable and has worked well for me, but YMMV! I've used it to log about 95% of my trips in my gen 3 using the EngineLink app on iOS. Here are some additional threads on OBDII apps for iOS: OBDII iPhone App | PriusChat
I too have an ELM327 Wi-Fi and have two apps for iOS: "FourStroke" and "FORSCAN". Forscan is specifically for Ford products, while FourStroke is all makes. Neither will do jack with codes for a Toyota HSD system
