how do you know if the v-tech has kicked in or not?

Answer 1

You should be able to hear the VTEC changeover and notice the change in power.

Although it depends on which VTEC engine you have.

Its spelled VTEC too...not v-tech

Answer 2

Depending on the model, ecu, and other variables. (stock, modified, etc.

Usually on the older B series dohc vtec models 1.6, 1.7, 1.8 there is a distinct tone change in the motor. Easier to tell when the crossover is in fourth gear so the rpms don't shoot up so fast.

So to hear is best i suggest shifting relatively early in 3rd gear so the rpms drop to 3500 then accelerate and listen.
Stock gsr 1994 engage at 4500rpm, usdm b16 is 5500, I have had jdm b16 that cross over at 5800, same as type r.

Hope it helps. Keep on asking if there are more probs,

Answer 3

never went vtec cause i turbo charged mine and dropped a b20 in it. but my ex had a 94 gsr and i could always tell by the tone of the engine, it seemed to be a higher tone. if your not in tune with your motor its easy for exhaust and intake to drown out the pitch of the motor. As far as feeling it thats a tough way, it is only 30hp and if you came from a vtec motor your not going to notice a HUGE defference. Also they do make vtec lights so you can have a little tiny red light go on when you vtec kicks in for those of you that are not in tune with your machine

Answer 4

V-tech is meant to be seamless in its operation. If you are feeling a decided change, then there is a problem with your vehicle and need to have it checked out.
Good luck.
