The 690 SMC's & Dukes have a switch setup for swapping FI mapping, but my 690 SMR does not. I am curious to know how much grief is involved in putting a rig to do that on my bike would be. I have seen the FI map handswitches that some aftermarket dealers sell, but there must be more to it, and I believe those switches only work if the preloaded optional maps are already there. Has anyone rigged something like this up on an SM/R and if so how did it work? Thanks!
