VTEC Window upper boundary setting
Posted: Wed Aug 03, 2005 11:26 pm
Okay, so I have a vtec upper and lower boundry... basically one for full throttle, and one for part... got the basic concept. The thing I'm missing / concerned about is what happens at high rpm when you let your foot off. Does vtec disengage at that point, since it is below 24kPa. If so, isn't this very bad since things float at that engine speed?
I can't imagine this is what is happening, I think I would have noticed this in a datalog by now.
Am i understanding the window settings correctly? I am under the impression that when you reach 24kpa, your vtec point is at one setting, then when you reach 90 kpa, your vtec point is at a different setting. I can't imagine vtec doesn't stay engaged at higher rpms if under 24kpa.
Perhaps the behavior is more like the following: Vtec point is at upper boundary starting since you're below 24kPa, then switches to the lower boundry when you hit 90kPa accelerating. Vtec point switches back to the 24kPa setting when the map drops below 24kPa.
In any case, help file wasn't very clear on this. I'm going to load up the seminar dvd and and trainging video files to see if I can find anything on it.
