I posted the same question asking for help on installatoin of the venom400 on hondatech.com and herez the thread... They all said it sucks??? ANY here that has it has any proof that it actually do anytihng??

I'm quite disappointed with the result personally after spending $200+... Please tell me that it works....

VXCL

how many of them actually have it? it definitley does something. they might not have the correct programming in it for their car. like i said it sucked when i was stock, but know it makes a very noticable diff. i will dyno it eventually and run it at the track soon hopefully.

I've said this before...The Venom 400 is best used when racing from a roll. I chirped my tires all the time doing roll races, which is pretty significant since I have a slushbox and am allmotor. From a stop it isn't that noticable. Its more for quicker downshifts and lowering the vtec engagement point.

I can def. notice a difference with it. I dunno if it was worth $200 tho. Downshifts are mean gettin on the highway and once after racing from a roll, it still seemed active at the next stoplight (I smoked an Accord 6 w/ the same mods). Too bad there's no way to make it active all the time (for racing etc..) I know I won't get rid of it till I get something better (VAFC perhaps).

CLpower

haven't looked into the venom 400. what does it do?

ib_jimmy

is it worth getting the Apexi VAFC for a 3.0CL?

CLpower

from what i've heard no.

DrDre1443

why is it not worth it for the 3.0???

CLpower

because you won't get much out of it. There isn't enogh tuning really to do to make it worth it. Now if you were turbo, or had some custom cams or something like that then yea it'd be worth it. But w/ basic I/H/E you won't get anything out of it.

JLai

I heard the opposite. I heard the VAFC makes a big difference...Given you tune it correctly. Much better than the Venom IMO. However, tuning costs $. The engagement point can also be set lower and you can get a smoother power band.

DrDre1443

see, thats why i think it would be really worth it b/c as you add intake headers and exhaust, youre upping the air flow and by using the VAFC you can up the fuel flow at certain RPM's and coupled with the VTEC engagement point it would really produce a good chunk of power......but then again thats my common sense viewpoint, i have yet to have any mods or the VAFC so only time will tell!

Butter98

From what I've read and heard, I agree with Dre and Rice. Only thing is, once you shell out the $ for it, you have to spend some time on the dyno, which can get pricey. The Venom aint bad if you can get it for around $100. Payin $200 or more and you'd be better off getting the OBX headers (more bang for the buck) and havin them bent to fit (for the 3.0's). JMO

CLpower

go over to the v6accord board and look it up. From what i've seen people have seen very little improvement from tuning the vfac on our motor. My opinion the minimum improvement isn't really worth the $$ (but then again, i've become cheap)

CLpower

has anyone here tuned a vafc? Just curious? What kind of results did you get?

VXCL

the venom chnages a/f ratio automatically, a vafc would do the same excpet you can get better results and mess with vtec. if i get a vafc the venom will be up for sale

dustbuster4

From what I've read, getting a VAFC (and paying for the dyno/tune time) isn't really worth it unless you are running some type of forced induction (turbo/supercharger/nitrous).

However, if you're ok with 5 HP or so from the VAFC on a N/A car, then I guess it's worth the cost.

There is more potential with a VAFC than the Venom 400.

JLai

I think we're arguing over two different things. Given we agree that there are more improvements the more mods you have and if you have FI. But...I'm saying it changes the way the car reacts more than straight up HP till later on mods. HP wise, not much is gained through electronically changing configurations on our cars.

CLpower

what do you mean by it changes the way the car reacts? yea it changes A/F ratio and vtec changeover etc. But none of that stuff is really necessary or benefitial for our car w/ the limited amount of mods we can do.

JLai

lower vtec point...smoother powerband...throttle response? (not sure about this one)----> won't be running rich anymore...better roll races...etc etc benefits

CLpower

i don't see a point in lowering the vtec at all. Esp. from the dynos i've seen the max i've seen is about 3 HP peak throughout the power band and alot of times it looks like they've had a loss through the ban.


What would be helping you in a roll race? Lowering vtec? If you are stepping on it from a roll when you downshit you should be right back in your sweet spot.

Not digging at you got rice. just trying to discuss, i'll look up some dyno sheets tomorrow.

97Acura3.0CL

i have the vafc on my 3.0 and i wish i could hsow all of you the power it has behidn it, you would be suprised, hopefully i will get some video soon of the car, but the vafc is good when you have all you bolt ons and you can tune it in on the dyno to get better gas milage and overall better performance. i tell people it feels like a powerban for a dirt bike, it kicks and and throws me back in my seat for a second, ask cilvr2.3 he got a ride in it and he doesnt have any negatives about it

DigiBox

I've had the Venom for a few years now and constantly have it on. When it isn't on, the car just feels like it is missing something. I like the quick downshifts

The Venom doesn't engage vtec any quicker.

I've rode in a 3.0 with the vafc and there is a nice difference when vtec kicks in. Just lowering the engagement point seems to help. At least it feels like it. The good ol' butt dyno..LOL

JLai

I dunno...Its really hard to explain unless you're had a venom or vafc. I felt a much more dramatic kick when flooring it with the thing on. Like I said, it might not be straight up HP gains, but the shifting is alot more aggressive.

truraysa

making the vtec engage earlier shouldnt make power throught out the band but give you more power from where you set it to till the original engagment point.(its just switching to a more agressive cam earlier) take for insteance drag racing, when you change gears you wantyou next gear to be in vtec, if not you'll be running on regular cam and then jump to vtec and same thing with next gear.lowering your vtec will keep you running the aggressive cam. tunig the is a good thing if your running alot of stuff (power will be more of a percentage thing, the more power you already have the more power it will make)
i think he meantt he veno is better in a rolling race cause it trick the ecu its in wot before it actually is which makes it down shift faster(for an auto that is). not really sure if theres anyother benifits.

CLpower

any chance you have a before and after dyno? Did you tune it on the dyno?

CLpower

i know how it works, i've tuned them on a few dohc vtec motors. Just don't see it doing any good in ours. I'm gonna look into it though. My thing is, i can't see anyone justifying spending 300$ on this thing and then another 150-200$ tuning for the power they are going to get. And if it's not tuned on a dyno it is basically worthless. Sure you can go the ghetto way and hook it up to the 02 but that's not really doing you any good.

CLpower

i've been proven wrong, i'd still only mess w/ it if the cam profile was changed but everyone has their opinions

http://www.v6accord.com/forums/showt...ight=VAFC+Dyno

torque plot looks real nice and kicks in earlier

CLpower

now my question is, who is tuning your vafc?

DrDre1443

the people on the V6accord website on that link are posting that some people are swapping their cams for some 3.2Cl-S cams....is that possible/easy/cheap? is there a better way to go for cams?

CLpower

it's possible, but alot of people are holding out to see what the new accord cams will do.


It's not cheap, but it's pretty easy. But no one has anything definate on the increase in power yet from what i understand.
