BigBirdSucks Posted August 27, 2005 Share Posted August 27, 2005 your VTEC should kick in around 5600 rpm. I don't know why you'd feel a loss in power unless you were using the wrong ECU. Link to comment Share on other sites More sharing options...
hellyeah!! Posted August 27, 2005 Author Share Posted August 27, 2005 i have a p30 ecu is that the right one? if not what should i have? it kicks in when the tach says 6000. Link to comment Share on other sites More sharing options...
airjordan223 Posted August 30, 2005 Share Posted August 30, 2005 i have a B16 SIRII in my del sol did you do the swap? Link to comment Share on other sites More sharing options...
hellyeah!! Posted August 31, 2005 Author Share Posted August 31, 2005 no but the ecu that is in it is the one that comes with the b16a3 in the vtec models. i think i fixed the problem by gutting out my catilitic converter because i can definantly feel when vtec kicks in.

blackdelsol Posted August 31, 2005 Share Posted August 31, 2005 that shouldn't make that much difference. mine doesn't kick at all, it just pulls slightly harder at around 5500 rpm. Link to comment Share on other sites More sharing options...
hellyeah!! Posted August 31, 2005 Author Share Posted August 31, 2005 well i can tell the diffrence from before and now. its not really a kick just a harder pull. like before it lost power as soon as it hit vtec until about 6500rpm's then i could feel it, but now i can feel it right at 6000rpm's (which is where it comes on at) and by "kicks in" thats what we say in hick vill instead of turns on.

..SSR.. Posted August 31, 2005 Share Posted August 31, 2005 There should be no "loss" in power. VTEC should never kick, even with insanely huge cams, it should always be smooth. if it kicks, your VTEC engagement is not set at the optimal RPM.

hellyeah!! Posted August 31, 2005 Author Share Posted August 31, 2005 no its not kicking when it comes on that is just what i used to say that it switched to the bigger cam lobes. like when you say kick in to 4 wheel drive there is no kicking involved you just engage it. my cat. was clogged up so that when it engaged it would be really loud (sounded like it was coming from the intake) but would loose power until i got to around 6500rpm's. and im comparing it from when it usta loose power to now when it gains power which is definantly a increase. the way i figured out that vtec lost power is that i got into some grass and started spinning the tires in 2nd and as soon as i would hit vtec it would bog down until 5500rpm's and then go up to vtec and it would do it again.
