I'm sure there are more con's than pros to this.. or everybody would have it like that you know.. and Honda wouldn't have designed it to kick in later..

Re: hondata s300
vtec needs to be set where the engine wants it set... not where u or someone told u it should be. the proper way is to set it on a dyno. You run one pass with the vetc set high then another with vtec set low. see where they cross and thats where you set the vtec to come in.

Re: hondata s300
The only way to really know when VTEC should engage is by watching your torque curve on a dyno. The old fashioned "butt dyno" is not the most accurate method. There is an optimal range for the engagement point because our engines are designed to flow a certain amount of air at a certain velocity during various rpm ranges. If you engage VTEC too low, you will increase the amount of air available, but lower the velocity thereby reducing torque. Basically, you will lose power if you set it too early. Finally, you dont need an S300 unit to do this. You could save yourself some money and go with Crome. That way with the money you saved, you can invest in some actual dyno time.
