Click to expand I'm not a hack i'm saying i've seen it before they just did it to see what would happen lol. I really don't know y they decided to put it on a switch but they did and it worked. And mine deff did hit vtec in neutral it was a y7 block with a d15b head and a d15b ecu and it would hit vtec sitting still and my friend had a hatch with an obd0 ecu and it would hit vtec in park. I had the d15b with the obd1 computer and it did have vtec in neutral and yea vtec won't engage at all if the car isn't warmed up or if it doesn't have oil in it.

But i meant vtec was on a button not a switch, so he could be driving and push the button and vtec would engage you could tell that vtec engaged too it got faster but only if you hit it at the right time if you hit it to early the car would like bog down. I checked to make sure vtec worked on my car by simply reving it up and holding the vtec selanoid. Actually no it really doesn't matter i get negative repped doing the same thing other people do so i don't see the point in trying anymore.

Ensure your Honda is capable of being "tuned" properly and can benefit from a VTEC engagement-point adjustment. This may necessitate the addition of aftermarket parts or other upgrades from the manufacturers' "stock" engine. Reflash your engine computer. This is likely the least intrusive way of changing the VTEC engagement point, as it does not involve any additional engine hardware.

Instead, the flash-based, on-board computer software is essentially reprogrammed. The design isn't a whole lot different from what pneumatic or electric valvetrains might offer, resulting in valves that can open or close at any time and remain open for as long as they want. If you're thinking of picking up your first Honda project or are ready to pull the trigger on a swap and can't decide which engine is going to be right for you, then check out this quick, basic guide to some of the best options available.
