I have the Ness Big sucker and V&H Big shot staggereds and am wanting to know which map should I be using with the SERT. Should I use calibration #67 or #89? Both are for a 2007 shorty dual exhaust with O2 sensors 1580 SE A/c and race exhaust. The #67 states "2007 Shotgun/Shorty Dual Exhaust with O2 sensors" and the#89 states "2007 HDI Shotgun/Shorty Dueal exhaust with O2 sensors". So what is the HDI?

 

Someone throw a dog a bone here....

 

HDI - Harley Davidson INTERNATIONAL models.....

 

If your bike has the variable intake and exhaust system it's the HDI.

I would venture to say you don't with the filter and exhaust set up.So use the 67 map. That's what I'm running with the 07 WG, SE air cleaner,Big City Thunder Monsters in the head pipe and modified SE slip-ons.

BTW, best sounding pipe now of all my riding buddys. They want me to do theirs too!

 

That is the one I am running. Will be playing with the Decel enleanment table to see if I can get rid of the pops I get from time to time.
