I haven't got it yet but for those asking, the difference between the III and the V is:
Cold Start feature that adjust fuel with engine temp
Can Flip between 2 maps with the flick of a switch (ie Fuel economy to performance)
Can power up using USB cable alone
Once i get it installed i am going to get it dyno tuned. We will finally have a definative answer on how much HP you can get out of bolt on mods like exhaust, PCV and an airbox mod. I will keep everyone posted.
O and i have a stock sprocket (thought about changing it but don't want to sound like a gnat on the freeway)
