I bought one of these on ebay a few weeks back. I have been playing with it. Shut off a code in the wifes car, which ended up to be an evap code. I had to replace the gas cap also.
There are a ton of apps for android that work with this device. The one I like best is called Torque. It basically does datalogging, and stuff very similar to what a $2500 snap on machine does. With a big screen, this would be real nice (maybe an android tablet)
It works wirelessly over bluetooth using your android cell phone. Most of the apps are free, some are like 5 bucks for a pro version. I didn’t have a need for a pro version.
At the very least it beats paying someone to read a code for you, or riding up to autozone to let one of the parts jockeys do it for you.
They do not work on iOS due to BT stack limitations inbuilt to the OS.
IIRC someone got this to work with a jail broken device, a full BT stack, and some sort of tweak. You need a WiFi OBD II module for use with iOS. You can get them ‘inexpensively’, but still considerably more costly than the ELM 327’s.
So you’re saying this wouldn’t work with an iphone? Sorry I just am a noob with this tech stuff. Everything in the listing that BadnewsMike posted indicates that it would.
