Hey mate, cheers for the response. From what I quickly searched on FAQs for Uprev, as long as it's properly unmarried, it should work.
I guess returning to stock should do, is there any way of finding out if you have properly unmarried it? Lol just don't want to get stuck.
Also do you know your ECU number (you can PM it to me) if you don't mind me asking, just wanted to compare with mine because I know there can be compatiablity issues (though your's worked fine).
:-)
