Lets make one thing perfectly clear here. There is no EFi system yet developed that can compare to a carb in terms of horsepower, torque, driveability, tractability or reliability for any gasoline engine manufactured to this day. The only reason the carb was abandoned in favor of any FI system was to keep those catalytic converters from burning. It is strictly an issue of emissions not usable power.
Even your most basic FI systems is far more complex than any carb. It is an extreme over simplification( bounding on criminal) to suggest that all you need is a PC and software to mod any Fi system to suit your needs in ten minutes. It takes hundreds even thousands of hours of very expensive development time to arrive at a mapping of fuel/timing that works without shortening the useful life of any SI engine.

this is very interesting stuff...first of all Im happy with my 907, but at low revs say 2 to 2500 revs it shakes (nothing a gearchange cant fix) then starts to smooth out at 3000, and you are wright re bit about pulling out of coners, but can this (torque at low revs) be improved...or can a 907 be more like a later model ducati by changing the FI system say a P8, and does it plug straight in or is it a re-wire and what about the rest...pick ups and sensors are they compatable?

Intresting topic, but very funny to read ALL opinions, as seems, that everybody have own attitude .... Thank's for all

ANYWAY i am in quite same line, as Angelix with things...

Have to add little: P7 is better with FIM chip, IF AMB circuit board is fitted to P7 and FIM chip is finetuned with FIM software. No any doubt; all carbs are crap compared to finetuned and well maintained injection no matter is it P7 or P8...

IF someone here have changed from P7 to P8 computer (in 907IE!!!), let us know results!!! (and then needs also some dyno run papers with P7 and then with P8...) I dont trust before i see such papers what confirm that changing ECU makes much improvments. Ok, this is little "side" from what Angelix say, but he is in right way and he have played with things to know...

Anyway; I love 907IE injection compared to any carb systems. (I keep my bike's fuel systems in clean condition allways)

907 Pasonut: "but at low revs say 2 to 2500 revs it shakes" ??? What? Such engine is designed to work FROM 4500 RPM upwards !!!! All such Ducati engines SUFFER ALOT, if drive them with too low RPM and if such happen, then u can find hard engine failure quite fastly... Simply, Ducati engine DONT work and it suffer if driver drive it with too low RPM....

It is difficult to find 14 to front in 907, but easy to find bigger to rear and that is huge imporvment to behaving of bike. I use 15 in front and 46 (!!!) in rear and never back to original gearing. Rear is same as in many Monsters, SS, etc... I really dont need 210km/h top speed but now i can use also bigger gears more often to reach allways good and suitable RPM in engine (as gears are now more closer to each others)

Just that way !!!!

here we go...the boxing gloves are off!!!
