vAFC and VAFCii

[xodus]

i was looking at the vafc and vafcII would they really do any good for our cars since we dont have real vtec? what would be the upside to getting it if any? i/h/e/im/pulleys/tb are the upgrades so far.

[CrackerTeg]

We do have VTEC, unfortunately its the economy version of it. Whereas the performance VTEC or "real VTEC" crossover is around 5400 (I think) where our economy VTEC or "not real VTEC" crossover is at 2200. The VAFC isn't a beneficial upgrade for our engines nor is it ideal for any engine for that matter. All it really does is switch the VTEC engagement point to whereever the tuner sets it at, but doesn't do much with the fuel and oil demands the engine needs when in VTEC. The best option out there for true performance tuning are standalone EMS's. You can do piggybacks, but they are not worth the money wasted on them.

ok cool , so has anyone tried the greddy e-manage cause i was looking into that and having a buddy tune it on the dyno obviously

[CrackerTeg]

That I don't know. I do know of a few people running K Pro. The only people I can think of that could run the E manage would be the J series guys. Paul (NVA AV6) would be the guy to tell you.

hm cause ive heard of it on the k24 with quite a few people i just dont know the results they got the the greddy emanage

[seththekorean]

* we also dont have vtec on the exhaust cam.

Greddy e-Manage are too me and a lot of other people junk piggy back management. Your best choice is to save up and get K-pro or AEM FIC.

VAFC's are a waste of money, and I've heard from a lot of reliable sources that Greddy eManage is pretty buggy and unreliable.  If you have a K24, your best option would be KPro.  AEM FIC is good too, but KPro is better and worth the extra money.

Yes and No Tim, it depends on what hes doing, either way if your just tryna make some extra hp with no bolt ons,.. you might make 5, 10 at the most with the stock setup, but for F/I the F/IC will be fine for you. If your going N/A and possibly an engine build get k-pro definately.

I say this because most likely you'll have to retard timing with F/I and it cannot advance timing, K-pro can and will do much more but for an extra $700 cost to ya over a F/IC.

So decide what you wanna do and then get a tuning solution appropriate for your plans, unless you got boat loads of cash sitting around  Either way stay away from VAFCs and E-manages!

* we also dont have vtec on the exhaust cam.

No Im pretty sure we do, but as always Skip will come in to confirm for all of us. But I think its the CRV a1 that doesnt have it on the exhaust cam.

[timot_one]

To be quite honest, it does not matter if you're going for a FI or NA application when you're building a motor.  It's a matter of which engine management system works the best.  For K24's, hands down it's going to be KPro (regardless of FI or NA application) with the AEM FIC coming in second.  You're right about staying away from eManage or VAFC's though.

As far as the exhaust cam having VTEC, that's a negatory since there's only one cam lobe.

[Skippy]

Timmy is correct.  I hate how I sometimes don't get update emails when posts are made....it makes it harder for me to jump in and give my opinion before somebody beats me to the punch.

Timmy is quite correct though, our exhaust camshafts lack VTEC lobes.  We only have VTEC on the intake side.

[thisaznboi88]

has anyone used F/IC to tune NA setup? I only seen them on F/I.

Im too poor to get Kpro right now maybe after this summer since I will be working 2 jobs hopefully.

[timot_one]

Doesn't make much sense to get the FIC and have it tuned, just to get KPro down the road and pay for another tune.  Do it right the first time.  You're going to spend more money if you get the FIC first, then KPro later, than if you just bought KPro in the first place.  I honestly don't understand why people say they can't afford to buy something, but then tell us about their half assed plans to do it a different way that's going to cost more money then if they did it right the first time.

[thisaznboi88]

what if I just want to do cams and retainers and call it a day. I won't be going F/I or any huge N/A just want to get it tuned for BC stage 2 cams. Probably the last mod I do to my car besides all the bolt on. Like if I was going for 250whp + I totally jump on kpro. But as of now I am looking for 180whp-200wh since that auto tranny going to Nada if i F/I or frank it... So yeah
