hmmm...really funny is funny...cause obviously you are biased against PC3. The dealer did M1186 (0903 product improvement) in front of me cause I was curious. It did not get in the way. In fact the ECM has an access port to hook the laptop up to... the PC3 does not have to be removed to flash them. All is good. and even if it did have to be removed... on a touring bike its like soooo simple.
They also told me this was a timing mod not a fuel mod and I would notice it wouldn't surge if I lugged it or putting around in idle @1st, otherwise probably wouldn't tell the difference. So far seems he was right but he admitted he couldn't actually call up the values. So off he went to do all the bikes on the showroom
BTW for some of us this is the first time dealing with this sorta stuff.
