Is AVC-R Similar to S-AFC II

[Peter_hii]

Can someone tell me what is the S-AFC II for?

i just got my AVC-R boost controller and i know that is to boost... i want to know is the AVC-R similar function to S-AFC II ?

and what about REV/Speed meter? what are their purpose? Thank you.

s-afc adjusts fuel mixtures

rev speed is just a gauge for speed rpm 0-100 0-400

cheers

What do you mean by similar in function? The AVC-R controls boost, the SAFC adjusts the air-fuel mix by modifying the volatge signal to the computer. The RSM monitors speed/revs/battery/trip etc, has 0-100km/hr and 0-100m times etc, removes speed cut.

If you mean do they all use the same sort of layout for the commands then yes, all the blue screens work very similarly.

The AVC-R and the SAFC are for performance the RSM is handy but not necessay.

See'ya:burnout:

Ohk ...i got what you guyz trying to tell.....thank you dude...

still got one question,,,i just installed the AVC-R. Is that necessary to fit in the SAFC ??

[KamikazeR33]

it will give u better fuel economy and more power in most cases

[Peter_hii]

And some more question related to the S-AFC.. when is the best time to fit in the S-AFC ? example: after installing intake system..

Can someone briefly explain the use of S-AFC? i mean what will this electric system do to ur engine? Thank you Dude..Do you know what i am trying to ask?

i am sorry if i write something you guyz dont understand.. APOLOGIZE.........

Super AFC controls the ratio of air and fuel the car uses, though it doesn't alter ignition. Tuners will try to alter the air/fuel ratio to somewhere 12:1, therefore giving better economy and power. Do a search and there's many threads on the SAFC.

All three have similar monitoring tools, but their main functions are different.

Oh yeah that is what i want.. thank you Silver-Arrowz

There is no real 'best time' to install the SAFC. It can really be installed anytime. If you're interested I have one for sale:

Forget the S-AFC, get a PowerFC if you can swing it. The AFC is only a small subset of the functions in a PowerFC.

[Peter_hii]

is it? thats mean all the function that the S-AFC got are exactly the same as the PFC?

[Silver-Arrowz]

no. The SAFC only has only A SMALL SUBSET of the PFC functions.

[Peter_hii]

ok... sorry my english is bad .. so .. correct me ..

[T0nyGTSt]

PowerFC = full replacement racing ECU with logging, programming etc.

S-AFC = piggyback air/fuel controller.

I didn't know PowerFC's had datalogging...

I wouldn't forget the S-AFC if your budget constraints were tight. The best thing to do would be to save up $700 or so for the S-AFC plus tuning, and when you save up an extra $1500 or so, sell the S-AFC and you should have enough to buy the Power FC and get it tuned.

That's exactly what I'm doing Pity that the Power FC isn't the first thing on my list of things to get so it's quite a way off yet

[Peter_hii]

ermm .. acatually i care about is not the budget, cause my hobby is to build up a performance car, may be two or may be three cars. ..

[JimX]

Then why are you looking at the S-AFC?

Well my friend you need to look at the PowerFC Pro + the AVC-R + Hand Controller.

That's probably the fat end of $2,500+ gone.

Or try a HKS F-Con Pro. They are similarly expensive.

You would be hard pressed to buy better at any cost for road cars.

i already installed the AVC-R and finding the best PFC now ...

so ... hehe...
