Not really for the R .. need one that will read any car ..

Oh right sorry mate thought you meant for the pulsar ..... you meant just a general obd2 reader then they are pretty much all the same ive used a couple of different brands and theres not alot in it from the cheaper ones what you kinda got to do is work out what cars as in a rough year say like from 2003 -2013 and so on bit like my boss has one it does petrol up to 2008 but only does diesel up to 2001 .... plus two types like ones that do like vauxhall.ford.etc dont do vw.audi etc
