As in the title, I was wondering if people could give their recommendation for a code reader. I have a 03 sti if that makes any difference to which scanner to buy. I would like one that can read real time values if possible.

 

An elm327 Bluetooth from eBay along with an app called torque on android, many use it and would recommend it, will give real time data plus allow to read and delete fault codes, won't work with apple phones tho but I believe they do a wifi version which will allow you to connect to a laptop, just have a browse through eBay, there are a few half about efforts on there tbh, don't let the cheap prices put you off, after all no point in spending a big amount on something that will do exactly the same job as the cheaper ones

 

ive got a memoscan cheap does the job,but i too have been looking at the elm327 looks a handy little gadget,heard good things about aswell.

 

I have one has well that i use and love it and it did not cost much at all
