I've got a mate whos currently struggling at IVA with the emmisions.

Car has a GSXR1000 K2 engine (2002) and it's currently failing CO at 1% odd between 2500-3000rpm, at idle it's almost zero.

It's got a power commander 3 on it (engine doesn't run lambda sensors but does have cat) and it's been leaned off with lambda showing 1 on a gas analyzer throughout the effected range but despite it showing the CO ok at the mapping place yesterday, it failed it's 3rd IVA today.

Has anyone got any ideas or preferably (miracle time) a map for a PC3 for a gixxer thou that will pass IVA?

Any help appreciated

Ta!

Maybe just needs the cat to get hotter? At my IVA (ZX10R) it was struggling until the inspector answered his phone and wandered about chatting for 10 minutes with the engine running at 2.5k rpm getting hot and bothered and suddenly all the numbers came right.
