Qnes on VAFC and SAFC

[Honda_insane]

Hi, i'm quite new to car modding....just curious to know wat do VAFC and SAFC used for?

Is it a good item for an auto car..me driving honda jazz?

[Ltcy]

Both VAFC and SAFC are for tuning of your Air/Fuel ratio. VAFC is for Vtec cars. So, your Honda Jazz should be using the VAFC.

For hondas use VAFC, others SAFC can liao cos no need the vtec function.

 

You can actually lean our your A/F mixture and set your vtec wild cam to open earlier or later. If your jazz is not the vtec version then SAFC for you.

so does u mean it make yr car more responsive and use yr fuel more efficient?

getting one will mean u need to send yr car for some tuning, rite?

[Koren]

tune you car according to the power ratio.. u'll feel the difference..

 

for jazz.. you should get the SAFC as it doesnt have vtec..

[Blitzza]

No effect. Waste money. I just sold my SAFC.

[Honda_insane]

hmm.....seem like same as other gadgets...some feel have effects...some dun....

anyway, thanks for all the advise....

[Vtec78]

u need a gd tuner to get gd results....some ppl say the learning power of jazz n fit is too strong, so after some time it tends to override the safc/vafc setting....wat i did was reset my ecu like every 2 mths....u can get the safc cos jazz bo vtec.....another advise is complete ur mods b4 u tune the safc....save money in this way.....

[Noregretforever]

yaay true..

[Noregretforever]

but issit worth the money anot...muz ask urslef..

The most increase in performance, and perhaps for some, FC, is if you've modded some parts of the Intake/Header/Exos before tuning with the likes of SAFC or VAFC (now VAFCII).

 

For e.g., with a better air intake, the engine is able to breath and rev easier. The air fuel mixture would also need to be adjusted so it's not too rich or lean (which leads to engine damage via pinging). If you use a CAI, the burn is also likely to be more efficient as well since a cooler mixture has less loss in power.

 

If your car is totally stock, you may or may not benefit from SAFC/VAFC, or even better ECU tuning like eManage or FCon series. Some benefits could be derived if your car is tuned too conservatively in the first place, i.e. too rich so as to prevent any pinging - car manufacturer playing it safe.

 

Lastly, the skill of tuner is most important. For eManage/FCon etc, performance maps must be customised to your car and level of tuning. Look out for those that will actually dyno their tuning results, along with special listening tools to hear for pinging at various driving revs.

For SAFC is it can only adjust the air fuel ratio? What elso can we do with it and How fast is the respones for you to feel it?

bro...understand tat u got install Broquet...want to chk wif u hw much diff in the car performance u felt after installing it?...

[Honda_insane]

hmm...if u ask me the broquet...ermm...dun think fuel consumption got improve....as for whether it helps in keeping engine clean...i'm not too sure. maybe next servicing i ask the mechanic....whether it worth having...the answer is no...i regreted.

[Turbonetics]

not much diff actually....

but they said if ur car minimum ron needed is 95,with Broquet u can pump 92 ron....

[Gary84]

hmmm...cos the broquet quite exp right?...The other time i was at mcwell the guy was persuading me to get it heng ah nv buy at that point of time...

[Gary84]

huh....so tat is its purpose huh...chey~ heng wa bo buey....

[Metalslug]

quite good, i have one on my civic. will intend to put on e fit if can change over...
