right lets start with why you shold fit the race ecu, the red line is raised and I have been told by Ducati that the timing is changed and the mixture.
You will have to take the bike and the ecu to be fitted because the ecu has to be set, ie throttle sensor has to be syncronised with the new ecu and the C'O value has to be set, there might be more but it was enough to stop this mechanic in his tracks, I dont have a mathiss(ie the computer that only Ducati dealerships have) and at thousands of pounds I wont be buying one any time soon,
shame as I like to do all the work myself,
as for the PC111 you will need one if you want the bike set up as well as it can be done, as the race ecu is set on the cautious side of rich, it's not even close but your bike wont burn a valve or piston. and that's why they do it.
So put the race ecu on and get a custom map for your PC111 and the best is as you know is an advanced map, please let me know how much you pay,
I hope this helps you
