Hey mate mate bought an op-com reader off ebay and we plugged it into mygsi and it came up with laods of stuff you can read and change settings on. no fault codes luckily
but just wondering how good these things are? and what other stuff you can do with it??
lookin at getting one for just reading fault codes on but then im thinkin about gettin something that reads more cars as i dont want just a vauxhall specific one
