I'm still working on my d16z6 swap into a 93 dx. I'm using the dx ecu and harness and I need to know how to run an external vtec wire to a switch inside the car(and is this possible?) Thanks, in advance.

 

yea its possible i never have done it but i know you have to run the vtec wireit to a power sorce and then to switch ... but someone on drag should have done this b4 and might be a little more specific

 

Oh wow....I can't see why you would do this. If you had no way to make the ECU control it, then why not make it a WOT switch so it's engaged as long as you are full-throttle and not on the rest of the time.

Not like it's going to make a damn bit of difference, but hey if it makes you feel better.

 

You can make a trigger for your vtec out of a shift light. Haha. Its the funniest shit.

 

You could just chip you ECU and add vtec to it. I would recomend doing that that what you are trying to do.

 

You could use an RPM activated switch... but for the cost and work, I would just get the ECU chipped or get a different ECU. You also need to consider the additional fuel requirement when you engine is in VTEC. Good Luck.

 

yeah....totally not a good idea.
there are seperate fuel and timing maps for vtec x over...
jesus....

 

Dont be stupid. Just do it right.

 

get a p28 and call it a day.
