    Spoke to Clive Woods today and it's going in for de-cat, exup removal, filter and dyno.
    TBH I can't believe this has not been done yet on this bike, unless it's against racing regs.
     
  2. Nope, not at all. You'll need either a dyno tuner who's got tuneboy or tuneecu on their computer, or your laptop with tuneecu on it and have a chat with the dyno guy, see if he's OK with using your computer & software. After that it's just a OBD2 lead (about £10 off ebay) and a bit of time. TuneECU will take longer to tweak the map than it would on a powercommander, but it'll do everything a PC3 would do, plus a few other bits and bobs.

    Download yourself a copy, load a pre-made map on it and see what you can do with the software. If you're confident enough, then plug it up to the bike and see what it does, but I'd leave the main bits of the the tuning to while it's being dyno'd so you can see exactly what's going on. Bear in mind that there's essentially 2 maps too: 1 which relates to the throttle position and is where you're going to get your power gains etc. then there's a 2nd map which doesn't have throttle position but inlet vacuum on there. This is for at the smallest of throttle openings, but in my opinion can be considered a braking map if you like, and can be used to tweak where the feel of the transition from a closed throttle to a neutral one and can get rid of much of the snatchiness you tend to find in these scenarios.
     
  3. So guys, what would all this modding cost in an ideal would? I'm very intregued =D

    About £90-100 for the headers or the hourly rate of your local fab shop if you can find a friendly one to do it for you.

    £60 for the filter (K&N, standard MWR) or £100 for the race MWR

    Dyno should be about £45-60 per hour (say £150)

    Should be able to get it done for less then £350
     
  5. Ow wow that's good... I wonder how much all this will affect my warranty lol
     
  6. As far as I am aware;

    First statement is correct, and as you previously stated humidity also greatly effects power output. More moisture in the air has the same effect as NOS/Megasquirt, further increasing the density of the mixture within the combustion chamber, therefore more compression = more power.

    Clive told me around £270 so what Trip Jim says is about right. I'm going for a MBC race filter.
