thanks so much for your input weejohn...GREAT comparison
from looking at hoodey's site/map..it appears it runs either ON or OFF in this application
http://www.bajanchameleon.com/5efhe_actuator.html
it appears you can build a map to suit pressure vs rpm to control how and here u want to short runners to open, but again this is an on/off position
i'd assume a more ""curved/variable"" point map may be beneficial for track/everyday driving
whereas a fixed on/off rpm point map may be ok for drags
to some people setting up a "variable" trigger for pressure vs rpm may not be worth all the effort, where to others it may be very beneficial
i guess each person would have to decide what's best for them
on another point, there does not seem to be any part opening for the butterflies in the short runners---ie 30%, 40%, 75%, etc
i know there have been some discussions where it was mentioned that on a stock 5efhe ecu controlled system, that the ecu may control partial opening of the butterflies based on load/rpm/etc inputs...
is there any concrete evidence of this, as i imagine it may be hard to partially open these items with the way how the vacuum actuator is set up
what i can see fluctuating is the point at where the runners completely open/close based on those inputs into the stock 5efhe ecu/set-up
just more information for discussion
