ok i been doing alot of thinking and once i get the ECU troubleshooting guide i will be able to try this. i have the apex VAFC II and i read somewhere here in the forums a guy with a v6 accord used the accelerator intput instead of throttle and it is working....well our vtec kickin and red line are only 1000 rpm apart and when we shift we shift out of vtec...right? well if you look at my dyno the last 200 RPM the power curve goes flat...im thinking if i lower the vtec engagement about 1000 rpm down to about 5000 rpm maybe 5200 we can stay in the high power band when we shift. im pretty sure we wont get anymore power from moving the vtec engagement. just keep our selves in vtec when we shift. that way we will be able to pull faster times in the 1/4 mile. imalso gonna redyno with the O2 sensor to see if i have anywhere to play with the A/F ratio. if i dont then shiet im stuck but if i can play with it and get a lil more power ill be happy if i can get 5 hp with the VAFC II ill be happy. will post when i have the ECU trouble shooting guide and can get the VAFC II working if not then oh well wait for something else to come out

 

That would be great to see a dyno with the air fuel readings. 1000 rpms might be a bit much to drop the vtec point; 500 rpms lower might well eliminate the vtec dip and give you a little bump in power. The only way to really be able to tell the best place is by doing some comparative dynos. With your intake/exhaust you'll definitely be able to lower it a little bit. Let us know how it goes.

 

I look at 5200 or 5300 RPMS....that would be just about right.

 

5200 is roughly 1000rpm drop...i just wasnt sure if the vtec was supposed to klick in at 6000 or 6200...all i want is a 1000 rpm drop

 

ah ok, it's a 6k stock! Let us know how it works

 

see thats what i thought it was but hey i just want to stay in vtec longer...ill let you know how it comes out..its gonna take me a while though i gott alot of research to do again
