in light of your quoted response, can you give an example by filling in the options in VTEC settings
Lower engage ?
Lower disengage ?
Upper engage ?
upper disengage ?

against below query.

i just wanted to get more information into standard VTEC application, your explanation seemed a little different than standard operating instructions therefore asked the above question in this thread.
it would clear all sort of confusions if you may fill this in respect of standard VTEC understanding.

Remove the "No," and you have clear instructions for how it operates. We did not respond to his specific example of numbers, we were simply trying to clarify operational logic.

Correct me if I am wrong, in online help of VTEC engagement window, instruction were different before recent update.
Yesterday it stated;
"If these were set to 500 mBar then it would use low engagement below 500mBar and upper engagement above 500mBar"
Today after the update, it states:
"If these were set to 500 mBar then it would use the upper RPM engagement below 500mBar (Lower load) and lower RPM engagement above 500mBar (Higher Load)."

Doesn't it change the logic altogether, or am I missing something?

Answered previously stating the advice outlined here was correct and the help page was updated.

Refer to datalogging to verify any logic differences on your application and good luck with the setup. Take care!

Thanks again
