obd2 reader and app for iphone

[Voldemort]

Can anyone recommend an obd2 reader and an app that will work with my iphone and said reader? Prices for both vary from a few quid to £100's.

Looking at my Amazon history the one I got was "OBDLink MX 426101 ScanTool Bluetooth: Professional OBD-II Scan Tool for Android & Windows" and I was very happy with it.

I say "was" because I sold the car and forgot it was on there

If it's for use with an iPhone, you may need to get the WiFi version, as Apple bluetooth does not connect with many OBD readers because of Apple's strange protocols.

Thanks for that: it's what I kind of expected... I'll do more research before buying and might just get the cheapest one that looks likely to work and see what occurs.

I was hoping to get a definite recommendation that *this* unit will work with *that* app.

I spent some time looking into this recently.

Most are based on an ELM327 design, but very few are genuine. The early version was easy to copy so people have done that. Unfortunately they don't support all the protocols and can be unreliable.

As newer versions of the genuine chip were released, the fake ones added new versions, but in name only. For example, there has never been a version 1.5 but loads are called 1.5. they are actually just version 1.0...

I think the cheapest real one is about £60, so I was tempted to buy a few cheap ones and see if any of them were any good. You can get an app to check if it's genuine and what version, but obviously you have to buy it to do that!
