My mate had one, bought it brand new, had it fitted for about a month then took it off and had hondata fitted/mapped. And obviously hondata was way better and wish he hadn't bothered with the spoon.
Not entirely sure what the spoon ecu is mapped for on the k20 but on b18 they are mapped for spoon exhaust and stage 1 spoon cams. As already said k100/kpro is a much better option and specifically for your car and your mods on UK fuel so better and safer
