Remapping necessary for slip on end can?
« on: August 21, 2016, 08:27:39 AM »
Found this quote from Stairliftman earlier in the year.

"Word of Warning to those that are running cans/systems without a remap, the fuelling is so lean lowdown as standard that if you fit an aftermarket can/system without a remap you are risking doing some serious damage to your pistons/valves due to detonation,especially if you are running on supermarket fuel/ high ethanol content :005:
These bikes need to be run on super unleaded to get the best from them."

Having read several latter post, all mentioning that re-mapping isn't necessary with just a slip on can, I'm rather concerned. :005:
Any update on this??

BMW doesn't recommend a remap with the can only...

Nope niether does anyone else but if you do you will notice a difference just as you will with headers and filter.

True - I had my Hayabusa ECU reflashed when I installed Yoshi cans...the difference was noticeable.
