hey guys i stumbled upon Aegisranger's post a few days ago and am going to attempt to do this on my 07 with a pc3 usb.
so far ive got all the software set up, and am going to try and get the switch figured out tomorrow.
okay guys heres where i am so far. i have downloaded the shift kill enable. i have installed it in the power commander. i have repined the 9 volt adapter. and i have ran wire from the adapter to the general area of the shifter. i spent most of yesterday shopping for brake light switches and thinking about mounting options. this is going to be a bitch due to us not having a shift rod. i am now leaning more to using a micro switch. i think brake light switches require far too travel and pressure to be applied.
also on a side note. i went on a ride last night and bridged the shift kill wires together at speed and i can confirm that it is operational! so yes you can put a quick shifter on a vfr with a pc3 usb. incase anyone is wondering this is done with a fuel cut, not an ignition cut/retard.
