Went out on my bike today and the weather was quite warm. The bike said it was 22deg.C. The exhaust was popping like mad all the time on the overrun. Is this a sign of a rich or lean mixture?
True. I'm not only concerned about the decell (so maybe my comment out of place), I'm curious to see how it's burning at cruise, WOT, across the band, a dyno tuned map vs stock. The only way I know how to measure with no Dyno, besides my heat gun, is reading the plugs. Assuming whoever writes the file does a good job, the mix should be better across the RPM band, and will also pop less on closed throttle engine break. Also dealers and tuners have told me the aftermarket map cleans up alot of the popping, however not ALL... What I'm curious about is the suggestion that Ducati writes something into the ECU (fuel droplets, whatever) to produce some of the sounds. I have no idea if that's for real or not. Seems odd, but these days alot of thing sound odd to me.Nope.
A spark plug doesn't tell you it's running too lean on decell, but too rich on accelleration below x rpms (or the other way around). Only a decent dyno operator with a wideband o2 sensor can tell you that...
Again true. And my bike runs surprisingly well considering the stock tune with mods, they've done a great job, no surging, or laziness, very liner acceleration, all that. I just know it can be better, and I hate the lean popping and all the heat. As long as the map not flawed, only performance to gain, and heat to be reduced. Good stuff in my opinion... Maybe not for everyone.Well actually, how the engine runs is also a very good indicator. Swift accelleration, throttle reaction, steady speeds, any surging...
The engine will definitely be running cooler, whether you as the rider can notice, people say so, but I cant say from personal experience on this bike. But as soon as I get the tuner I'll flash it and post an update.Is it even possible to reduce the heat of a hot engine to the point you'd actually notice?
Yes but other brands like Arrow and Zard don't seem to care to much even though they have to follow the same rules.Of course they are, else they can close shop (in Europe).
