Hi cossack84,
yes on DDFI 3 system there is a step motor opening an extra air passage (IAC).
Up to now I am not sure why it is also moving around a lot, as it seem to be governed by engine temperature only.
Warm up Idle.jpg• Looking at pw 1 and 2, rear cylinder is most of the time leaner than the front.
• Sometime injector are not going together, I mean one pw is much higher than the other.
• With the bike idling with untouched throttle sometimes you can see pulses from Acc. correction (up to 4.5 or so)
• In the meantime TPD is floating between 3.5 - 4.5.

I am having an hard time trying to discover the logics behind ECM decision, as the few useful info’s are spreaded one by one all over the net.
I love my Buell, but it seems that Eric's guys left a lot of job to be done by costumers.
As I enjoy learning and put my hands 'developing' my bike I am not so unhappy with that, but I hate they (ISD?) did not supply us with full info over their DDFI systems.
Really I don't think they are so good to worth keeping them secret.
Looking for everybody opinions, up to the next.
