I agree on the spark plug comments - mine works and I have a spare just in case it doesn't.

The ECU question is probably one for Kev, but I do not think it's possible to connect to the standard ECU - let alone re-program it..

The PC enables the user to create custom maps, so can be fine tuned to any bike. If you're going for the full air box mods, then to get the best from the engine you'll need a free breathing pipe (I have the X Racing single can) and at least the Kev fuel mod (I've got this too). Kev is working on the 02 eliminator, but even with the 02 sensor in place and connected Kev assures me the fuel mod is working fine. I've not done enough miles yet to really comment, but I can say that compared to the standard set up my K&N/Snorkel removed/X Racing/Kev's fuel mod spins up better and is much crisper - sounds better too!!!

Without going into the engine and making changes, I'd suggest the Scottoiler too. You can lose power through an unlubricated chain.
