Clean as! Was wondering what your car looked like (seen you on grparallye.com) but now i realise i've seen it before!
Do your research and be honest with yourself with what you want from the computer. There are pLenty of choices so it comes down to capability and $ really. If i was to do things differently i'd have gone Autronic, basically a MOTEC (arguably better) and cheaper. Then again if the basics of timing, ignition, knock injector, and a few other simple senors are all you need to control PFC's can be had new on ebay for cheap. Shop around, good luck!
