doea anyone know how i can get the shift light rpm activated switch on a tachmeter to operate the vtec solenoid ?

 

This is just a guess......but Ebay sells that kinda stuff

 

you have to get a tach that has shift light then set the light to turn on when vtec kicks in.. Why do you want to shif when vtec kicks in?

 

no i want the shift light ta activate the vtec so when the shift light comes on the vtec kicks in

 

wow. this forum gets worse with age.

A light is not going to make V-tec "kick in". It doesn't work that way.....

V-tec engagement is set by the factory in the ECU. Getting a new ECU, (ie. mugen) or V-tec controller (ie V-AFC) is the only way to adjust when it engages. Odly enough a Shift Light can be programed to turn on at a set RPM that you designate. So I would just set your light to the RPM in which V-tec gets engauged. Like say 5,600 - 5,800 or so. This number will fluxuate if you have a non stock ECU, V-tec Contoller, etc.

This only works if you have solar powered vtec.
