93' H22A Build

[H22]

Regardless, it won't get any benefits without a proper tune/replacing some interals such as more aggro cams, all you'll do by changing the crossover point is stuff things up and probably lose power, the engines designed with a certain vtec engagement point which is based off the components and current tune of the engine such as the profile of the cams, the tune it is currently set to etc.

As long as your ECU aint tuned for that exact crossover, ur car will run lean and you will loose power, running lean will make your engine suffer, also your wallet int the end. If you want lower VTEC engagement, get a tunable ECU and have it retuned as for your wishes. Could be everywhere from p28 with Chrome, Neptune, Hondata to a simple piggyback. Hondata IMO is a bit overkill tho for this kind of build.

VTEC controllers should only be put in a car with at least some kind of tuning device, cheapest route is a piggyback wich probably would work gor your build. but best way is an tunable ecu.
