    Hi everyone, I have a 2003 VFR800

    Here are the mods I have currently installed.

    -Power commander III (the serial connector one, not usb)
    -K&N air filter
    -Pair, Flapper, & snorkel mod
    -O2 sensor eliminators
    -Delkevic Slip On Exhaust

    Anyone have a map I could use? I tried using some that came with it but none smoother out the VTEC transition.

    Search for the 'coyze' map, it's well known. Try the vfrdiscussion site if need be ...

    VFRDiscussion has a bunch of maps for Power Commander, 44 listed. The 'Coyze' map seems to be the one everyone likes to go with.

    I took one from the PC site for my PCIII, I modified it significantly so at my usual cruising speed of 90 or so, it leans out for better mileage.

    Unfortunately the famous "Coyze" Map is only for PC3 USB, I guess because the PC3 only does increments of 500RPMs, vs the PC3 USB allows adjust ability in 250RPM increments.

    Luckily I figured out a solution... I went ahead and download the PC3 USB software along with the Coyze Map, I then recorded all the values for every 500 RPM increment. Then I went into the PC3 Serial software and manually imputed each value into the corresponding RPM and % Throttle. After triple checking my numbers I uploaded it to my VFR and took it for a test ride.

    Oh my god. It is amazing! The throttle feels soooo smooth now! And VTEC transitions perfectly now! Exactly what I was looking for! Thanks guys!

    I sorta want to sell my PC3 serial and get a PC3 USB or PCV and try out the map with the 250RPM increments and see the difference, but for now I'm just going to enjoy my bike!

    The only thing I still notice is popping on decel, but I heard that's normal and I guess it's just something I can deal with.

    The threads I find with the Cozye map all seem to be dead. Can someone post the PC3 file, or a file you like better / modified further?

    I'll see what I can do. If I remember when I get home i'll take a photo of all the values and you can just copy them down and transfer them over.

    It's a really good map, very smooth VTEC transition.

    Prior to installation of the PC3 were you experiencing popping on deceleration with the K&N and Delkevic exhaust?
