Apexi VAFC for our beloved Honda...

[Riezal-R]

so does that means that a vafc is useless without setting the iginition timing?

no point adjusting the vtec to open at 5K + adding sufficient fuel at 5K above?

Unless you want to use if for fuel economy, which you might as well just buy SAFC :)

The VAFC works well on its own too, depending on application. But when paired with the ITC, it functions even better. They work well together.

And as zero4 says, it really depends a lot on the cams you are using.

sifus,

provided i have vafc & itc only, how do i know at which rpm
is the 'earliest' i can tune the engine 2 'engage vtec' at?
do i trial & error all the way? mine's a small v from da6,
std engagement pt is around 5000rpm
thanks

 

[zero4]

dyno machine is there for a purpose, i would say :)

 

[syiokGILER]

if that the case .. just using safc is enuf .. no need to alter the vtec engagement point .. juts alter yur air/fuel ..

 

[minivan]

riezal is right, minivan you shud see the screws they used for local produced cam pulleys, u will be surprised how fragile the screws they produced looks, and they ARE that fragile


that's why u hear ppl say, mine damn tuning lari, LOL

yeah, i know, pretty scary...
and carnage... yes there are...

Dyno will be best, if you have the cash. Trial and error works too, but too much will damage your engine.

For road use, usually lowest VTEC engagement is about 4800rpm. The mech tuning your VAFC + ITC would know and make sure he does, or else he shouldn't be tuning the stuff. Can be harmful if you dont know what you're doing.

Before any of you invest in buying VAFC + ITC, try do some homework on re-chipped ECU. It might be just nice for you.

 

[zero4]

yeap, re-chipped ECU are usually good enough, unless you are running high cams.

reizal, so you are the one disturbing those ppl sleep (staying near SMTTIDI) in the middle of the night huh? hahhahahaahhaah

no worries, i test my car there too, LOL

Riezal.... for discussion purposes... in what way can it be damaging??

running too lean, for starters :)

The road just nice to drag 2-3 gears laa. I make about 5-6 runs then I cabut to LDP, then drop by there again on the way home. But since the nasi lemak makcik selling there, must wait until she go home first. Hahahahhahaahah.

sound true and logical enuff.... any comments sifus??

 

[Riezal-R]

As mentioned by zero4, too lean will damage the engine. Too little fuel going in. And I was told that if you adjust the ignition timing wrongly, it can also be harmful for the engine.

For the VAFC2, they have the 'knock sensor'. This sensor will alert you if your tuning can cause harm to the engine. But I'm not sure how this sensor works. It is included only in the VAFC2.

LOL, ohhhh, u testing on the nasi lemak makcikc road ah, i testing behind that road loh, the road after the traffic lights one, hehehehehehe, but that road got corner a bit ler, but can push until 4th gear i think

 

[SePaT]

ok


got a Q here



someone wanna sell to me .. a programmable chip that can do launch control on

desired rpm.. came with shift light on the desired rpm ( your check eng lite will function as shift light ) rpm cut .. speed cut.... and of course vtec engagement


have anyone of you have this kindda setup of re-chipped on your ecu .. ??

launch control?? i assume more often we heard it from turbocharge engine to avoid late spooling on bigger turbine.. but what abt vtec?? do we really need it??

 

[zero4]

honestly, for non turbos, we dont need launch control :), i think our legs are able to handle the launching
