Question about 2008 Ducati 1098
I have a 2007 Ducati-1098 with 3K miles. I bought it about 6 months ago from the origional buyer. It has a Termi full system, Race ECU and Power Commander. It felt a little rough after i purchased it, so I checked the plugs and they were fouled. So I changed them and the new plugs fouled. I took it to the local ducati shop for a Dyno-tune and they said they could not get it to tune they had the bike for almost two months!...they said the bike wanted too much fuel. But they said it would run good with a zero map. They did not know what was wrong. So they put a zero map on it and sent me home. When I got home the plugs were fouled again. I changed them, rode the bike for approximately 10 miles, noticed it was still running rough, checked the plugs and sure enough they are fouled...I mean pure black and sooty. I do not know what is wrong...Anyone??? Please help??? Thank you for any help.

Theoretically a zero map in the PC effectively eliminates it from the fueling circut as though it wasn't even there. Theoretically. I have one in mine and from what I can tell it does. That includes plug reading. So, assuming that's the case, the problem lies with the ECU fuel map, the adjustments in the circut or a bad sensor (engine coolant temp, ambient air temp,engine rpm, throttle position and I believe barometric pressure) giving false info to the ECU. It could also be something as simple as a filthy air cleaner. The ECU does not sense A/F ratio or mass airflow and relies solely upon a fixed map for fuel. A dirty airfilter would cause the richness. Were it me I would do a plug cut on the front cylinder at a steady highway rpm to see if it's rich at that engine speed and load vs only at idle/low rpm. Rich lower ranges will crap up a plug in no time and a cut will tell you if that's the case. Rather involved process but doesn't lie. The ECU map is rumored to be rich in the lower ranges. If that proves to be the case then it would be a simple matter of reducing fuel, via a negative map, in the rich rpm range. Given that they had it for two months and claimed they couldn't fix it would give me concern as to the qualifications of the dealer. It's just a machine and as such CAN be straightened out. I wouldn't buy into that at all. Lastly you can remove the PC and eliminate any possible effect it MAY be having. Not that hard to do, remove some bodywork and fuel tank, disconnect the PC injector connections, reconnect the stock ones and pull it out of there. Going back to stock is always good practice when confronted with something like this. Also you can then go back to the dealer KNOWING the problem is with the above mentioned stuff and KNOWING that it CAN be fixed if they've a mind to.
