Do you mean what is the lowest RPM at which VTEC will engage on a stock car?
If the engine is stock there's not need to alter it, has been optimised from the factory. If modified for more power with bigger cams then it could be beneficial but wouldn't be set any earlier in the rev range.Quote:

Just get a VAFC and have a try, you will get beaten by any non-vtec honda's
i was reading the manual on my dads 04 jazz, and it says VTEC kicks in fully before 3000 rpm, so i dont no if it would be the same for your car
Where is this thread going tekkin_DC2?
Be SPECIFIC in your question so we can give you a propper answer.
earliest is around 3500rpm. standard comouter can do itQuote:

Whatever.... you totally missed the point... again.. i didnt even ask what "the best" ecu was.. and for the "search" explaination.. thanks captain obviess.
just wanted to add, there is no point having vtec x-over this early.
In fact, oil pressure is probably not high enough for a SAFE transition.
The only reason to ever do this is when tuning, and even then its usually around 4k
wtf man,
vtec aint like boost...
u cant jst engage it earlier and have more power dude
if ur engine is stock, leave it as is
5200Rpm...not lower...
exactly what i was about to say.Quote:

get real,Quote:
