just wondering if anybody knows what mph their vtec kicks in as opposed to rpm. my boy has a jdm type r swap in his 99 hatch and his vtec used to kick in at 25 mph in 1st, 42 mph in 2nd, 60 in 3rd, and 80 in 4th. now its not kicking in till 35 mph in 1st, 57 mph in 2nd, 77 mph in 3rd and dont no 4th. anyone have any ideas what the hell is going on. he doesn't have a tach so rpms mean nothing as we don't know what the rpms are... thanks for helping.
