Need Advice on S-AFCII Limited Addition !

[Soundstream]

Hi Guysz,

Need your advice/help on the SAFCII on the setting stuff,

Can i know what is the correct and adviceable setting for,

Setting Menu

-Throttle Lo/Hi % ?
-Ne-Point ?
-Dec-Air ?
- Knk Set ?


Sensor Types
-Hotwire In/Out ?
- Flap In/Out ?
- Presure In/Out ?
-Karma In/Out ?


As i just install 1 yesterday on my VDO engine. The thing is the mech.
setting is slightly not same as the guide book.....


So any of you guys with VDO engine there installed SAFCII. Mind to share
your setting with me >?


Still a newbie for this stuff.


Thanks ppl !!!!

:) :p ;) ;) :D :rolleyes: :cool:

thr hi lo depends on urself..... the % indicates the thr flap open how many % eg. if u set 10% lo n 30% hi... your car will run on low fuel map after the thr open 10% and on hi fuel map after open 30%

 

[Soundstream]

Confuse...???

hmm,

what is the purpose if we set lo/hi ?

what if i set lo 25% snf hi26%

what is the advantages on this ?

mind to share with me...

thanks ya !

VDO engine?? I never heard of that b4.
If u have bought a new set of SAFC2 please read the manuals.
However.. i need to tell u this. wirings must be correct especially the air-flow (in-out) the pink and orange wire from safc must be correctly wired to your ECU. (Pink and Orange for karman type airflow sensors) most mitsu engines are karman type except for the 4G92 Mivec. How much you got your Ltd.Ed. SAFC2? :D

I suggest you dun play with the fuel map since you may not have enough knowledge in this area. Bring it to a mech with at least wideband o2 tuning so they can tune your SAFC for you. For best results, dyno tune... but only available in KL... sigh. No engines will have the best preset optimum SAFC settings. Thats why apexi do not have any tuning guidelines for it. Gd luck!

just to add few more stuffs.. if your fuel map correction are all 0% there will be no effect for lo or hi throttle settings... as how you floor your gas pedal... the airflow will have no change. The factory ECU will still take control of your fuel needs which is safe for the time being. Setting -ve correction (running lean) is very risky as you may blow your engine.. setting too much +ve will cause fuel overflow (running rich) thus u'll loose power instead of gaining... and cause premature spark plugs damage & clogging your combustion chamber with carbons.

In the SAFC there are two airflow correction settings based on throttle position and engine RPM, say... while u cruise on d highway.. you step on d gas pedal at 30% effort... thats your throttle position.. if u set your SAFC lo throttle position at 30%, means the SAFC will use the lo airflow correction settings. Suddenly u see a V6 crusing pass u.. u decide to overtake him... this time u floor the gas pedal all d way.. which means 100% throttle position. This time... if your settings for throttle position for lo is 30% and hi is 50%.... (now u are at 100%) which means SAFC now will use hi throttle airflow correction settings instead of the lo airflow correction settings.. Get it? lol... seems difficult for me to explain too... hope that helps.

So if the throttle is below 30%, the SAFC will use back the ECU's original air fuel ratio setting?

 

[ftzone]

Glocker.. it depends on how u set your airflow correction for lo throttle. What I said earlier is that if your didn't set any airflow correction (all 0%) den u'll still use the ECU default airflow.

maybe by reading this write up u may have more idea how the SAFC works.

ehehe

yo bro,

Thanks for the input.
Well now i understand clearly. I bought 1.3k + installation...
N off coz i read the manuals but quite lots of words which confuses me.
Dat's y i'm here dude.. ; )

:D

safc on VDO system ... didnt have TPS signal to SAFC ,

Coolblue

KSP when got Lelong Cheap sale ah? :p

 

[Soundstream]

what is dat bro.....TPS ?

safc on VDO system ... didnt have TPS signal to SAFC ,

THrottle Position Sensor. = TPS

.

may I ask how does it different from other Mitsu engine? Is it because of the MAP? I'm running MIvec too and have been thinking of plonking an SAFC if my budget on standalone engine management is restricted :(

thanks.

 

[PutraCraze]

wah... the price is 1.3k kah...

 

[ahchuan]

hmm... just asking few question here..

i went to dyno setting for my vafc, but i didnt see any increase in power when i'm driving.
but after few weeks, i went to my mech, he set for me, i can feel my car respone more fast and more light and hav a better fuel consumption. why ar??

my mech told me the shop didnt set my vafc, coz all is still at 0%.
the shop tipu me, coz i my dyno setting on the mechine just less then 15minute.. vroom.. vrooom...vroooom...finish... then pay money.. WTF!!

 

[Soundstream]

no meh ? hmm so what is the function is the TPS ?

n y no TPS on VDO engine ?

please verify...

thanks
