I rode up Devil’s Staircase in Wales last weekend on my 23 V4 PP. it’s a 1:4 incline and a few hairpins. On every hairpin as I opened the throttle nothing happened until I really wound it so I had to negotiate each hairpin at 8,000 revs riding the clutch. If I eased off the revs collapsed to tick over. As you can imagine this was a little disconcerting to say the least. It works fine when not under the extra load of an extreme hill. Rang the dealer and they told me it sounded like traction control thinking the tyres were spinning and I should recalibrate the tyres. Given that the wheels weren’t losing traction and given the same happened in urban and touring setting this is a strange diagnosis. Anyway there was no indication the tyres (TPS) needed calibrated, which I have had when I changed the tyres. Anyway ideas? It’s in for a service in June and I can’t get it looked at before then and under normal load it’s fine. So far.
I experienced something similar on a a steep corner on a narrow 1:4 hill, the engine lost power to the point where I stopped the bike then had to pull away using my best hill start skills. I put it down to the anti-wheelie system kicking.
If it's any consolation, I once cried with despair halfway up the Devil's Staircase - It was pouring with rain, getting dark, and I had a massive rucksack on my back, and if I dropped the bike I felt I'd never get it upright, even if it was ridable - I couldn't face going up, and I couldn't face going down again I pulled myself together and made it up OK
Dont know Im afraid , I ride that road a lot on V4s no issues at all up or down . Only thing is my anti wheelie is off so makes it great fun on the way up.
Definitely sounds an electronic issue. Give it a bash on a 1098R! Seriously though, I believe there is an accelerometer on your bike. This gauges multiple parameters simultaneously (lean angle, wheelie angle, ABS etc). My mate @Martin Ducati Glasgow had a 1299SL and his accelerometer started playing up leading to all kinds of power loss fuckery. Maybe get it checked out at the next service. IIRC in Martins case it was the physical position of said sensor.
I've intermittently experienced the similar on my 23 PP. Very steep inclines low gear , low speed, steady low to medium revs, full to medium fuel tank. Not a total loss of power but some power surging.. and revs dropping. Increase the revs up over 4500rpm seems better but still slightly noticeable. I guess the anti-wheelie theory could be the issue. I also read/watched somewhere that overfilling the tank can cause stalling problems and not sure if this is related, or maybe related to EVAP system... I don't know though I had my dealer look into it and they couldn't find any faults... Hasn't happened for quite a while now but do tend to increase revs uphill at slow uphill speeds and never over fill tank.
I was working on the theory that the Ducati Wheelie Control (DWC) system uses the inertial measurement unit (IMU) to determine any lift of the front wheel. rather than using the wheel speed sensors to detect the front wheel slowing down when in the air.
Just that the BMW's put the brake on for you when on a hill and I was wondering if the Duc had the same but something wasn't working right.
I have my different road modes set so "urban" has quite high TC and WC with soft engine power and soft suspension. Working through to 'race' everything gets reduced. Once, on a really cut up road in the rain, I was in urban mode and at each up hill section, on a tight bend, the power was being reduced so much the bike was trying to stall. I stopped and switched it back to "tour" (which has stock settings I think) ans the bike was fine. The way I had "urban " set up was causing the problem as the electronics were interfering too much. I can't remember which pass in Italy it was last year (horrible thing, gantry style hair pins, steep, mega tight 180 turns, rain, never again!!) The bike was still struggling in "tour" so slipping the clutch at every turn was essential to get up.
