Refresh old topic for 20V SVT/BT ECU putting SAFC or NEO???

[TRDae92]

Hi, forumer, some might already talk about this topic before, so just to refresh the topic.

Can the 20v SVT/BT ECU equip with SAFC or NEO for adjust the fuel ratio??? Just one of my friend install SAFC into his 20V BT so he sms me saying " warr, the power now gain, no like before, like adding racing clutch ". But of course i won't going for it cos i got IMEC ecu for my own. Well,kindly share u guys opinion.

From my personal experience with 20v BT, running open ITB, auto ECU, yes I can feel the difference in fueling with the blue screen SAFC. In fact my highway mileage can go better than 15km/liter of fuel with normal driving (110kmh). For me, it does the job well.

Although there are people mentioning that that Toyota ECUs don't work that well with SAFC due to the nature of "self learning", however on my auto ECU it seems to work just fine.

Regards.

So there if setting nicely there will be no piggy back result lor??........anyone have use other electronic device for controlling the fueling??? SVT or BT.

hello..from my experiance using safc on 20v svt/bt is good.hp sure gain only 7hp-10hp.i already used it almost a year(blue screen)..but using safc in svt or bt we must use bigger abit d injector.bcz what did my mech sed using safc is not for improve our fuel ratio.1 of my fren use it later his piston crack.at first we donno why n how dis happen.n then my mech do some abit r&d, saw the fuel not enough at d piston.he try to increase the fuel but still got knocking..at last he put some big injector.the problem occur..

what am i telling is, using safc is good.but we have to change bigger abit the injector.dont throw away o sell ur safc.just change ur injector.use GSR..:regular_smile:

~cheers~

If can, i oso want to ask some ques.....

SAFC2 fix to 4age 16v non tvis ok arrr......got differents arrr?.....will i have to change to bigger injecters toooo????

Do any of the Toyata sifus know or can recommand me to go install and dyno tune safc2 ???? what i mean is some pro for toyota one

thanks in advance

7-10hp increase with SAFC,thats a lot,and how did u know that,can you show us the dyno chart before and after the setting,thanks

Change to a bigger injector??? are you really serious????
SVT or BT injector already 295cc.which is good for 200bhp...
emmm you should consider checking ur fuel piping or your fuel pump.

Actually last time I installed Pivot ACS oredi... Power and F.C also not much improvement.. Then I take out and install APEXI AFC... Performance and F.C gone worse.. Coz i read from the APEXI Manual not support AFM type Air Flow.... Hahaha.. So both also taken out oredi...

 

[wfhan]

my curiosity from the old previous few topics discussing this, by only changing the ecu (without whatsoever mod of adjustable pulley, disable of vvt, etc...)
many have said that piggy back ecu won't do much good due to the 4age 20v stock ecu auto learning & has the tendency to re-adjust itself after some time.

But some said can and gain improvement from their experience, 'til now, this is still a myth for me due to my lack of knowledge and newbie in this area,.
well, can someone provide more details of explanation on the successful case that what is to be done to somehow 'override' the auto learning of stock ecu, and make good use of piggyback either on svt (afm) or bt (map) ? is the myth busted or not ?

i heard people said 20v cannot use safc..true ah? can it be bolt to blacktop with map sensor?

Yes, i also read the oldest apex'i SAFC 5 knob button one, the wiring diagram didn't include for ae101 ecu which mean for SVT, state that not support AFM type, only got the ae111 ecu wiring and i read the pin is for black top use only. Well, glad that some forumer share the experience and also do ask other helpfull question.

so thats means any safc will work on blacktop with MAP sensor?now new safc price around rm1000 plus, might as well get greddy e-manage..hmm..

yes.get emanage.its much2 more powerful than safc.But....still all depend on the tuner.....hehehhehe 20v tend to be too rick on the midrange and high end.there is still more power in it.And 10-15bhp from NA is very2 good.

A small question.. Ur fren using svt/bt?? Injector is Sidefed rite?? How 2 change topfed injector??

 

[TRDae92]

corolla92levin bro,

i'm not clear which engine u running now??? svt or bt??? about ur friends engine, svt/bt???......and about the injector, if ur friend not running turbo mod no need to change the injector to bigger volume size ler???? as GT20v say that 20v svt/bt injector is already design 295cc per pieces borrr??
