I am looking for information about the Polaris Stage II ECU flash you would get when you buy a Stage II kit. I have intake, exhaust, clutch, fuel controller already so I just did the cams instead of the entire kit. I am curious about the ECU flash, if Polaris will sell just that, and if it interfaces well with the Yoshimura PIM2. I also have the O2 DATA mapper from yoshimura but I am waiting on an x-pipe so it has not been installed yet.
