Apexera SAFC & VAFC

[alexklg]

hi, i don't think it can be done. many discussions had been going around on our ECU and its tune-ability but so far, i do not see any substantial proof whether we can tune Siemens.

hmm... maybe i should change the ecu straight for betta performance... any brilliant suggestions on good ones? axt? obit?

safc 1-button vs 5-buttons

i'm planning to buy an safc 1-button or 5-buttons type to install into my 1jz and get it tuned, how good is the 1-button type compared to 5-buttons or both compared to safc 1? anyone can recommend a good tuner shop in town to tune my 1jz? my ecu's already chipped, how do they tune these type of ecu?

any suggestion and advice would be most appreciated. thanks

I plan to fix LT8 to my Gen.2. Possible or not?

 

[ecupro]

zeroxseven,
You quote:
"I plan to fix LT8 to my Gen.2. Possible or not?"

Bro, first of all, LT8 not support electronic throttle body or "drive by wire".

If you really want it, you have to mod your throttle body like Proton Putra, Pron Waja (Mitsubishi type) or Mivec, then, connect cable to your foot throttle.

And, other thing is, you have to check on crank sensor ( i think on flywheel ) and cam sensor ( on engine head ). You need those input sensor to trigger the injectors and ignitors.

Good Luck

APEXi AFC Neo compatible with i-VTEC?

Guys,

I'm confused.

APEXi's web site states that AFC Neo is not compatible with i-VTEC engines, but local tuners are telling me that it is.

AFC Neo seems to be newer than the V-AFC 2, but is priced cheaper.


The thing is, I've got an i-VTEC engine, which should I put in? AFC Neo or V-AFC 2?


Thanks for the help guys.

Help for the above?

Thanks EcuPro for that info. Ancus Arapan....

hallo ZTH sifu's...
got 1 more question..

is it installed the safc can damage some part...
i think my TB wanna be (KONG) in this time...what i was heard if u r not properly install it has to be..

i'm using 4G92 DOHC Non Mivec and the engine code doesn't has in the manual setup..so can i using the mivec setup...it's same ECU for mivec n non mivec ..

1st day i installed it my engine can't start...(RPM drop until engine died) so my tuner adjust the timing @ TB n then it's ok..

Just Wonder..dont know if my TB really kong coz it's from h/cut..

Lastly for u all info after install the safc my fuel compsumsion it's very2 ok...0.12 Cents = 1km

thanks..

be carefull if ur fuel mixture 2 lean boom engine,i tink ur afs ny tuned properly coz ur symtom happens when its hot in da afternoon i tink ur afs not reading the air temperature properly causing the ecu to nt calculate the air density properly causing wrong air to fuel ration and thus making ur knock sensor go haywire.

hey guys, may i know is there any good tuner (with dyno) for safc in a 4age 20v engine? and how much is the charges?

thanks!

SAFC2-Dyno or Road Tune?

Hi Guys,
New to this so please bear with me. I have a standard Accord 90 with a SAFC2 hooked up and the person who hooked it up for me set it but the car was pinking badly and felt underpowered. So i decided to get it tuned at Sunway with a dyno and my HP increased by 5HP on paper. Now this felt like how my car was before i hooked up the SAFC2. And the fuel consumption was the same before and after dyno tune. In effect, i did not feel any difference in power while driving and in fuel consumption (before i installed it and after dyno)
My problem is this, i installed it on my standard car to get better fuel consumption (primarily) and if the power was better or smoother that was a bonus. But now it seems that its the same!
So is the SAFC2 only to increase power? Is there anyone who can help me tune it for better consumption without pinking? I was told by the dyno-tuner that SAFC2 cannot give you better fuel consumption but only increase power a bit....is this true??
I have read many of the write ups here and my eyes are swollen and blur....but i do know there are many sifu's here and any help anyone can give me is greatly appreciated.
Thank you.
Mel.

SAFC11-Dyno or Road Tune?

Hi all.
I am new to this forum and have read many great and extensive reporte on the SAFC2. However i still have some questions and given that i am new at this i hope all of you would put up with me.
I installed an SAFC2 on my 1990 Accord primarily for tuning to better fuel consumption. The person who installed it manually tuned it and i found the car under powered and pinking very badly. So i took my car to Sunway and got it dyno tuned and the pinking stopped and apparently i got 5 HP more!But the tuner told me that SAFC2 can only be tweaked to get a bit more power but would not better my fuel consumption. Further, my fuel consumption is the same after dyno and before instalation of the SAFC2. The power is the same too....so my question is does this SAFC2 work to cut fuel consumption? If it does work, is there anyone who can tune it for me?
I bought this unit 2nd hand and was told it will cut fuel consumption and increase my power a little bit....so far i have seen neither and my car has been tuned 2 times!
So i would appreciate any help from all the sifu's in this forum to help me in any way to tune my car for better consumption without my car pinking.
Thank you all,
Mel.

u got it all wrong
first thing first
if u got a modded car then only get a safc
if not its waste of money n time
a safc will only reduce consumption if the current tune by the standard ecu is RICH , then u use SAFC to make it stoich
if the current ecu is not giving enuff fuel , then u use safc to add fueling
in my opinion , anyhting less than 10hp will nt give u the kick of extra power , 5hp is nothing la bro , if u say 100hp then u can feel it, 5hp increase cant be felt
and tuning on dyno really need good expertise
if the load is nt adjusted properly , the tune will be fine on dyno bt will nt be on the road
my opinion , sell off the safc or keep it till u mod ur car

 

[melsolo]

Common sense...

jinkl,
But aren't all cars in stock tuned a little rich by the manufacturer? If so, wouldn't fine tuning it give better consumption by runningg a little lean? I do not know the technical details cos new to this but merely using common sense....And 100Hp is a very heavily modded car bro....u tell me 30 hp ok la, can feel, even my car 5HP i can feel the difference....but 100 HP , that is already race car la....

Mel.

 

[jinkl]

bro im just giving example about the 100hp thing
my saying is that , u cant get much or expect much for stock car
consumption might be better bt nt noticeabel few bucks gone down cant notice mar , n its good u could feel the extra power
bt i always choose on road dyno , cos u run on the road everyday n not the dyno machine :) , if ur car is pinging , then u r most probably running lean rite
the reason y they make it a lil richer is to increase the lifespan of the engine, its still very near to stoich

 

[melsolo]

jinkl,
thanks for the info...at least i know now roughly what to expect...By the way, who can road tune and how much would it cost?
Thanks again.

 

[heefmy]

tune on road or dyno is not the same....

in dyno they use big wheel under ur tyre to determine n calcualte ur hp, the different car have different load or weight, rim size....so dyno is not 100%

if tune on road then is the 100% then go dyno ur car for hp or torque. a bit danger la....for tune on road....last time i tune my acr on road for 4 hours.....full tank fuel gone.....charge me average la.....

i tune on dyno for 3 times.....then last is on road tune....i feel can feel road tune is more suitable for my car la...anyway my car is wira hybrid 1.8 mivec, emange

dont consider the hp for all time....torque is the most important.....the powerband graph for ur car...which point is the max torque n last how long for the torque...next time u race u can follow the shiftpoint to accelerate.

fuel comsumpsion Rm70= 450.....70%highway, 30%urban

as ur case.....safc2 can tune to save fuel de but u will lost a bit power.....more fuel more power this is the characteristic for car engine

 

[melsolo]

Heefmy,
Thank you for that great illustration. It has opened my eyes a bit nore and what you say has made a lot of sense to me. For that i thank you sir. However, i do have one question....who did your road tune for you? Was he good? How can i contact him? And how much did he charge you?
Once again , thank you sir.
Mel.
