I have a 2009 Cross Bones in Japan and need some help getting it to pass emissions testing here. It will not pass the cold start, too rich. What can I do? re-MAP?

 

Thats gonna be tough. Assuming it is bone stock. In cold start it is open loop, wont run a whole lot leaner than it already is. Will take a tuning expert, whom I assume will answer you today sometime, with better knowledge. Never attempted to tune there myself, always working on the nice warm go fast mode. Sorry for the no help, good luck.
