can you adjust the vtec without a controller. i would like to bring it down so it would kick on like at 4500 rpm instead of 5500.

im prety sure u need a vtec controller
can u use a vtec controller to adjust it then take it off? or will it go back to the factory setting?
yes you can mod your vtec to crossover without a vtec controller, you must chip/modify your ecu.
if you have minimal mods, the default settting for Vtec is already at the best position. the only way you can tell whats the best vtec crossover is by putting your car on a dyno. i seen many cars making the vtec crossover too early, and instead of gaining power, they loose power.
