Do I need a PC3?

Just wondering whether I really need a PC3 as all I have on the 1098 is some termi's with the DP ECU?

Anyone seen any dyno runs on these and the differences? I'm assuming any difference would only be in the mid range rather than top end?

If set up right, fuelling on the stock DP ECU is pretty good at full throttle. There is some mileage in tweaking part throttle points to improve feel and rideability low down. These are the "benefits", I wouldn't promise any more power although you may get a bit...

Having the TPS reset and the base fuelling setup and balanced is easy and cheaper and is always my first choice before throwing 400 or so at a PC and dyno setup.


.....but better in YELLOW, or Bloo and now even RED

That's what I had thought. I know how to reset the TPS but what do you mean by the base fuelling setup (setting the CO?). I assume the balance is just ensuring that both throttle bodies are synchronized?

Yeah, pretty much. The 1098 isn't like the older bikes though. Don't touch the balance bar on the throttles or the stop screws. You don't even take the lid off the airbox.
Reset the TPS. There's no idle adjustment as it's servo controlled. Balance the throttles using the air bleeds and then set idle CO to around 4%.
I'd get a couple of runs on a dyno then to see where you're at and go from there.

Is the 4% CO because of the DP ECU as I thought the standard CO reading was 0.7%?

The PC3 sounds like it's of more use for road bikes rather than track bikes.

4% is pretty much a common all baseline setting. The 0.7% is for tree huggers and keeping them happy. The 4% richens things up a bit and the Ducati like their fuel.
Tbh, the PC probably suits road bikes more in that it's the low speed response that can be tweaked. Race/track bikes really need any low down civiality and as the top end fuels quite well, it needs less work.
Basically, to answer your question......Do you have a problem?? If not, save your cash for fuel, beer and curry and enjoy the bike I've tried all sorts of parts and add ons without really seeing any benefit, other than just having them on the bike. If there's an issue with the fuelling, then a PC will probably cure it. I'd get it set up first though

I did wonder where the 0.7% had come from in the 1098 workshop manual as i'd been used to aiming for 4% in the past. Never really noticed a problem with the fuelling and if i'm not really going to find masses of mid range then I'll do as you say and spend the cash on something useful like tyres or beer.

Tbh, if the bike's running fine and/or your happy with it, then tyres and/or a suspension work over will work for you much better.
The front end is pretty good from riding my own and usually a few tweaks will sort it. The rear can be improved as it's too hard and has no sag. K-tech or JHP can work it over for not a lot and the benefit vs. 's spent is much better than a PC.
