Switching Point

[senjam1]

Whe does the map switch from low to high?

[Spunkster]

whenever you set it to?

[megomaniac]

the switching point is when you go from the low cam to the high cam. (vtec)

when is the vtec switch on is it on the lower boundary setting or on the upper boundery setting?im kind a counfuse when i look at my data log it switch to high speed table when it reach to lower boundary? is this normal and is it mean that the vtec is already on?

what is lower boundary for?
what is upper boundary for?


thanks

Please read the help file: http://www.hondata.com/help/smanager/vt ... tec+window

[allm0t0rGSR]

lower boundary=low to hi speed table
upper boundary=hi to low speed table

i dont know i still dont understand?
can u pls tell me how u understand what is lower and upper boundary?and how it work plssss...

[fly_n]

cruising/light throttle/low engine load = cams switch at upper boundary
racing/WOT/high load = cams switch at lower boundary
driving somewhere in between low & high engine load = cams switch at interpolated value between upper & lower boundary.

what the ecu determines as low or high engine load according to upper & lower boundaries is set by the figures u enter to the right of the rpm values.

thanks alot...

what if you put the same rpm for both lower and upper boundary let say at 5000rpm is it still the vtec will pop up at 5000 rpm?

[fly_n]

yes,if u read the particular settings tab in question,it says thats how u disable the boundary window,by setting both upper & lower at same rpm value,then it will always switch at that one value regardless of engine load.
