Well yesterday I made a post about the vafc hack, And with all the help on here plus with the help a google lol I managed to get my car to boost till 7psi fine with the stock injectors. Anything over 7psi and that car would start to pop real bad, Alot of you told me that for this to work I would need larger injectors. Well I made some calls last night and I managed to pick up a set of 450cc blue tops.

So this is were I start today, 450 blue tops + Vafc. I also have some of the self FMU but I think all that is going to be used for is a paper weight lol. As soon as I get the 450's installed I'll update some more.

if you're boosting on stock injectors with the afc hack then you're going to blow the engine within a day. the afc hack assumes you have bigger injectors.

SOHC_MShue

Fail

the "hack" consists of using larger injectors and trimming away fuel.

you're doing it wrong, seriously.

there is a reason why there isnt much current info on the "hack", because you will blow your engine. it was popular for for awhile until everyone starting blowing there motors. and also for the fact you can pick up a chipped ecu for alot cheaper than a vafc.
but anyway, if you stay at a low boost setting it might last for awhile, or forever, but who wants to stay on low boost? boost is an addiction

did it ever accour that I had the vafc before the turbo setup was even a thought in my head? No it would not accour to most of you because you to quick to put some one down.

Yes I know the vafc hack is not the right way of going about it but lets take a moment to think about who's car and who's motor this is...... Ummm It's mine not yours. I didnt ask what yoor opinion of the vafc hack was, I didnt recomend this to anyone else. I chose this for my purpose not anyone elses.

Also I was NOT looking to boost some crazy psi but only to be a DD till the tune. If you would have taking to min out of your busy *** schedule to actually read my post you would have known this.

W.e Im done ranting now

jdmdc529

accour ?

EARLdaSQUIRREL

if you dont want people's advice or them telling you your stupid then dont do stupid things like a vafc hack!!!

like i said in your other post that is still active (*dont know why you started another post when you already have one*) sell the vafc and use that money to chip your ecu

91civicDXdude

AFC hack works and there is nothing wrong with using it especially temporary. The problem i see is you're not doing it right and you're going to blow your engine, but what do i care, its YOUR engine not MINE.

get some 450s, trim the fuel -20%, retard timing at the distributor and boost the **** out of it

inspyral

AFC hack is so 2002
As stated above, it isn't an ideal setup by any means, mostly because of the screwed up timing maps you'll be running as a result of having to set fuel trim to -30-40% in order to idle those 450s. If you do decide to use it as a temporary setup, I would suggest retarding your timing at the distributer(or via a boost/retard box, but who runs those anymore?) and keeping the boost relatively low. Again, I would strongly suggest you sell your AFC and get your ECU socketed and tuned(Crome is free if you can't afford ECTune, Neptune, Hondata, etc). I ran the AFC hack until the screwed up timing cracked my ringlands, so I'm not just talking out my *** here. Good luck with your setup, whatever you decide to do.

What does you having the VAFC before you got the turbo have to do with tea and china? That doesn't justify a reason to run it, lol. What you should have done, was sell the VAFC to someone dumb enough to buy it and then use the money to get a more appropriate tuning solution, injectors, and a fuel pump.

OR, you can cut your losses with the VAFC, and get the above tuning solution before you blow your engine and spend 3x the money plus the tuning solution for the next time anyway.

I am also 95% sure that you're "tunimizing" your car without a wideband. AND, that "popping really bad" is because the car was going stupid lean/detonating like a ****.

This thread sucks.. only one VAFC thread per noob per month please.

come to PR...you guys might learn a lil bit more about the Hack..
A LOT of cars run here for Years with the hack...some of them are even 400+whp cars

You might be surprised to see the 1.8lt Mirages running 11's all day long on just the AFC Hack..

just becaue it didnt worked for you or many others... doesnt mean i cant be done.

Yeah on MAF cars, not hondas which only run MAP's where the stock ECU's advance timing because of the way the VAFC is set up and spliced in.

Free tuning software is only a tiny bit more than the hack cost wise, it doesnt make sense to not run it.

so if you have the afc already then sell it and get a chipped ecu . Its better to do it right the first time so you dont waste money buying a new engine when it blows.

quik sol

considering the vafc advances timing, then yes you would want to retard your timing to counter act the vafc so you have less chance of detenation

the guy told you many many cars run it with no problem. I never said it was good, i never said it was better than tuning, i said it works. If you're arguing against that then you're the retard becuase it does work. I simply stated that it sounded like he was running the AFC hack without bigger injectors which will ultimately lead to a quick and painful engine death. I ran it on my boosted single cam 4 years ago before i could properly tune it and the car lasted over 6 months of beating the hell out of it before it blew a head gasket from having reused head studs. sounds like YOU don't know what the "freak" you're talking about.

Ah, but alas, DSM logic doesn't apply to Honda's. Don't forget, Honda ECU doesn't know what a turbo is, so the hack adds timing instead of pulls timing like it will on a DSM ECU.

*In for the "OMGBBQ I BLOWED UP MI ENGINEZ! HELP HT!" post*

riddlinkid1986

wtf, the VAFC dose not change the timing.... or dose it? As far as i know you can only change when you hit v-tec, an +/- fuel.

I have my turbo si with a base maped p28(550cc boost base map), an a vafc in there also. Now i know when i get it tuned i wont ever need the vafc so i will disconect the map back to stock. I used the vafc to add fuel to richen it up to be safe. lol i mean i went +7% from like 3k-4500, then like +15% 4500-8000 to be safer. An i dont rail on it all the time.

But im running 550cc Tuner Toys injectors an aem fuel rail/reg at 40psi fuel.

Im only running about 7psi, i use the greddy e-01 boost controller as well.

Man, if you dont have a base map'd ecu that retards timing under boost you will blow your car man lol. iv seen it. my addvice is to buy a base map'd ecu from pharable.net for your car its like 200 or so an it plugs right in, but you still will need atlest 440cc injectors to move the fuel an walburo fuel pump. I put mine in befor i turbo'd my car an i could tell it was way better.

you cant manually adjust timing with the vafc, its the way that the vafc tricks the ecu that it automatically advances it, alot.

Read my next post....I said it works on MAF only cars, not MAP only cars like hondas......and I am willing to bet that the hack and advanced timing under partial throttle boost helped to kill that HG of yours....
