lmao @ vtec fuel.
and i need turbo fuel too, hahahahaah

no, you cannot change the Vtec crossover on a stock engine; you need a Vtec controller, like a VAFC. but if you dont know what your doing with these, you could loose power.

As for vtec fuel, it might have been Vpower you heard about.. its made by shell, its what I use. Vpower has a lot of cleaning agents in it to help make and keep your engine clean, because gunk build up is bad! Also its a high octane fuel, perfect for the lude, and advancing your ignition timing.

Yeah VAFC by Apexi can do the job and they are the most widely available. Spoon and another company that used to make it is Data System. They have similar vtec controllers but are not as fancy as the VAFC. All of them are from Japan and not cheap ($300+ new). If car is not tuned properly with access to a garage with dyno, probably best is to leave it out.

You can also buy a Buddyclub VCon. However this can only adjust the VTEC crossover point, and it isn't clever enough to engage the VTEC fuel and ignition maps when it moves the crossover point.

Moving the VTEC crossover point without modifying your engine is totally pointless anyways. In stock form VTEC kicks in when the torque curves cross for the two different profiles and maps. Moving VTEC to an earlier crossover point will lose torque down low, and moving up the rev range will deprive the driver of valuable revs.

Leave it where it is unless you've got as a bare minimum I/H/E done. Remember, there's nothing worse than shifting into a hole where there's no torque.
