I did a manual conversion on my 33 but kept the auto ecu using the usual tricks, but now I want to get my ecu nistuned... obviously can't with an auto ecu so just wondering if I buy a manual one will it plug straight in? Or does the loom need modifying/replacing with a manual one. Apologies if this has been covered but I can't get a straight answer and research via google image is confusing me hah. Cheers for the help.
