Earliest VTEC can come on

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.

the ONLY 'safe' point to allow VTEC to engage is where you have sufficent oil pressure i.e >~60psi

if you engine makes >60PSI at 1500rpm, it is 'safe' to engage it there...
