Yes, KJSatz, i too am very interested in knowing what kind of MAP values to expect that indicate the change to i-VTEC.
Overall the R18 seems to a very sophisticated little beast. But from reading the link you posted along with another tech brief from the same place that overviews all of the engine's features, it seems to me that the key to getting into and maintaining position in i-VTEC operating mode is to be very very light on the gas whereby rpm's matter quite a bit less. It also states that other factors are taken into account by the ECU --> this brings me back to my first questions about RESETTING the ECU. Is the ecu learning some of my driving behaviour and thus forcing performance over fuel economy more often than not? From what I understood prior to this, the grand majority of low end cars do not have ecu's of this kind and that 'learning and adapting to driving behaviour' type feature only comes with a porsche or likewise.
The fact that rpm's are almost irrelevant as long as one is between 1000-3500rpm's with an R18 engine makes me wonder about my past driving techniques. Now I am definitly starting to see where a scangauge would've helped quite a bit in figuring out this quite a bit earlier (although I wouldn't have a clue as to why). Assuming the ecu is smarter than what's good for it, do you think resetting the ecu would provide an opportunity to help retrain the ecu to the tunes of fuel economic driving? any other benefits/problems with the reset?
