just wondering if the vtec is controlled by the computer? if so is it possible to make the clp change at lower rpms like the s model? just curious.

what are you talking about? ofcourse you can change it ! the cl-p is already lower than the type S 4400 instead of 4800

clp is 5500?

i read that in the faq too, but you definatly hear the crossover around 4500ish rpm on the cl-p. Weather it actually engages or waits till 5500 i dont know.

Its been discussed before that the FAQ is wrong. The CLP crosses over earlier than the S

its lower on the P models because the Type S can make more power than the P motor @ lower Rpms...but u can change it with a Vtec controller like an Apexi Neo

Unless you have come serious mods and have extensive tuning knowledge I wouldn't attempt to change it. Acura set it to its current RPM for a reason

you know, i thought i felt it kick in around 4500. i thought i was imagining it. i guess not. thanks

i thought the apexi neo controlled the fuel output. i didnt think it could change when the vtec kicked in.

How VTEC Works:

the chip controls when vtec kicks in but in the dev days it was done off of oil pressure alone.

Changing it will slow you down.

I got a CLS and past 4800 when the VTEC kicks in, it's beasssttty as hell. But like some of the people here said, Acura puts it at a certain RPM for good reasons. You better bring your A game if you're trying to tune the governing software on the VTEC.
