AFC on 4G15

[1603]

will a AFC work on a 4G15 engine??????

kindly advise

 

[ruhaz]

as long as it's injection type engine and got computer box...can!!!

u put in for wat? better upgraded ur intake n ekzos system....do others thing 1st...AFC can do it later

my fren was asking me this question after he ask about RSM

so....just get more info

Yes u can use safc on a 4g15 engine.. as long as it is not a step 2 engine i.e car model 2000 and above are fitted with siemens ecu which cannot be fitted with safc.. but before u do decide to fit in one.. go for engine mod first.. such as cam.. tb.. overbore the intake and so on.. that will give u a nicer response when u tune the car with safc.. but do bare in mind.. a stock ecu will need at least 2 to 3 days time to relearn all value from the sensors before it can perform at its peak.. do a lot of research first before u do anything... u'll save a lot of time and money.. ;)

 

[bnr34]

yes. can. but no point.
cos u cant get more than 5hp with few hundred dollar.
some more need to take risk of being kena smash window.
even in 4g93 also get 5hp only.

 

[jee_square]

Sure can work lah as long as its fuel injection... No mods then no point installing one..

 

[thteh86]

afc....there's a point putting it in, ur air fuel especially

 

[edgar_raphael]

you can fit it.. its even better if you can try to squeeze something out of it.

 

[Wajafly]

Don't put SAFC2 and risk them being stolen. I've lost my SAFC2 and SITC just recently. Somebody stole them. To recover the 7-10 crank HP losses from them, I use my friend's product called JUICE

 

[boyzone]

can we put in afc to get better fuel consumption ?? pls advice

 

[huakenny]

1.5 itself oledi quite safe fuel..juz maintan ur engine well is ok.....put in AFC or not doesnt help much...my 2 cent......

s-afc on 4G15

I do aggree that a 1.5 is an economical car, how ever the fc depends on the way you drive the car. Puting a piggyback such as the s-afc would only optimized the fuel curve.. hence if tuned correctly.. it will defineatly save fuel. but once again.. the fc depends on the way you drive and the condition of your engine. If all the sensor are working 100%.. it should be an economical car unless you made some mod to the engine which would increase the fc.. ;)

SAFCII n RSM can b installed on wira with siemen ecu.
jus need to fine the rite person to do it.

 

[thteh86]

yeap....it can be fitted in a VDO siemens ecu.... and furthermore....4g15 fc good? i mean, i'm driving one and i felt that it's running very rich

 

[ijnek]

well...for a start,dun use bigger than 15 inch rims...
for mi,i'm getting something like rm63 for 515km(old fuel price at 1.52 per lit).
i have not top up my fuel tank yet with the new fuel price...

 

[torque_wrench]

aloo fren...
can u borrow me the diagram to fix rsm (siemen ecu)?

 

[Gti]

yes. can. but no point.
cos u cant get more than 5hp with few hundred dollar.
some more need to take risk of being kena smash window.
even in 4g93 also get 5hp only.

er...last time before mine got smashed...i got 13hp extra...dyno proven at gta
so it's actually worth the money but not the risk of ur car being smashed..

 

[Gti]

Yes u can use safc on a 4g15 engine.. as long as it is not a step 2 engine i.e car model 2000 and above are fitted with siemens ecu which cannot be fitted with safc..
can anyone explain y?
my fren's wira se plan to put one oso...but i told him exactly the same thing...that the new ecu cannot put safc...
then he ask me why...i kenot answer liao...simply saying that ppl in zth say so...
care for deeper explanation...any sifu?

Siemens ECU is "self-learning". It uses a closed-loop mode below 3000 rpm, if I'm not mistaken. In closed-loop mode, it will dynamically adjust the fuel injector pulse duty cycle based on the readings of the lambda sensor, airflow sensor, etc. to maintain cleaner emissions. So, if you introduce some device to fool it into running richer or leaner, like the SAFC, the Siemens ECU will just compensate for it based on what it picks up at the sensors. You'll just end up with no gain. For instance, if you intend to use the SAFC to make the engine run richer for better acceleration, the Siemens ECU will detect from the lambda sensor that you're running to rich, and it will just reduce the fuel injector pulse duration to lean out the mixture.

For the MMC ECUs, they're using fixed maps, which can be fooled by the SAFC and other such piggybacks.
