when I installed my turbo on my b16 I set the vtec at 4400rpm, and when that vtec kicks in, it was like getting hit from behind by a 18 wheeler truck, I get planted to my seat!

 

turn v=tec activation off on the V-afc drive with it like that and after a while like an hour or so turn the v-tec activation on and see if you feel any difference...race the car when you're testing it without vtec and than do it with

 

Sohc Vtec is hard to hear or feel engauge period..

 

if you just want to know when it enguages, get an indicator light.

 

just get an ls/vtec civic sedan i think my neighbors in afganistan can hear me crack vtec. go outside right now, dee if u can hear me, i dont care where u are...

ok... figured it out. i was flooding too much fuel into the motor when vtec engaged. to elaborate... i am running 450cc dsm's w/vafc on my NA crx in preparation for when i get my turbo on. my settings were -46% all the way accross. however, i had set it to -40% on the vtec unmatched screen when i first installed the vafc, which apparently overrides narrow/wide throttle settings. i figured more fuel for vtec right? wrong. too much fuel = bogging. leaned it out to -45% and now i can feel it. i guess i underestimated how much fuel each 1% of 450cc is.

 

i dont htink i could even feel vtec engage when my car was na ---- with the greddy exhaust i could barley hear it

if you want to "feel" it kick in then just drain a quart of oil out of the oil pan and run around. the solenoid uses oil pressure to activate the higher lobes.

every time I would get about a quart low on oil I would be able to feel it as it swapped over to vtec (damn thing would lunge back then pick back up)...that's when I knew it was time to add more oil :P

 

what u can do is what we did...we converted my frenz 98 ex to stick. he now needed a manual ecu so we then got a p72 ecu. vtec rips on that lil' sohc now. u can hear and feel the crossover. u could do that, but there's only 1 prob. u have an obd0, so u can change it to an obd1 and get a 94-95 p72. i garantee that'll work.
