i thought this was not a hack,but wiring the safc like it should be.could you tell me how to set mine up?im running a dohc zc im my crx right now i have a t3 turbo,a vortech fmu,hks ssq bov,and intercooler.it runs nice but it forces me to never realize the full benifit of boost (5psi.)i already have a safc-2 installed and i have dsm450cc injectors but those are not installed.i just need to know how to set the safc-2,like maybe a link to some pics as a guide on doing it.the fmu works nice for now but i want to try something diffrent on my other zc engine.anyway thanks in advance.........oh by the way i want 8 psi-but if 10psi is possible without melt down i will take it.

 

read the FIRST POST of this thread... thats the "hack" (tuning on the negative side of correction) anyone else know how to get rid of this code? im also having hard starts (even when the car's warm) and it stutters for a few secs....

The hell with the hack and all these other workarounds. Get a better solution for less money - Uberdata

 

oh.its no good?i thought i would work well judging by the comments made in this post.still if someone will tell me how to set my safc-2 that would work.when i try i doesnt save it for some reason.i would really like to hear from the creator of this topic.

 

sooo does anyone know how to get rid of my code?

 

I am needing a little help with the afc hack settings, my setup as follows, the cars a 2000 Si, with Vortech SC w/aftercooler, gsr cams, vafc, Precsion 440cc injectors, Walboro 255 pump,etc, thats just the main things i need to state. Anyway i finally setup up the hack to run with my 440 injectors, before i was running the FMU and check valve, and after about 3 weeks i was getting a CEL for rich condition bank 1, and kind of figured the problem was that my fuel preasure is to high, running at 50psi static. So i installed the 440 injectors and setup the hack at -40% across, and i am still getting a rich condition even with my inaccurate air/fuel gauge(PLX wideband on the way), I wanting to know do i need to lower the settings more, or if i had more of a adjustable FPR and lower it down to say 35-40 static fuel preasure and then raise the afc settings up some. Really since my main problem is with the fuel pump putting out to much preasure, and my B&M fpr not giving me adjustment, it wont let me lower the preasure only increase which i dont want. Thanks, hope i gave info, and please help me out, i am only running the hack until i can get it tuned and hondata installed.

 

i just about read this whole thread over the last few days and it was very informative, but i have a question of my own- i have a 94 hb with a JDM B16 swap, t3t/t04e turbo, dsm 450's w/resistor box, vafc and-the tricky part- a 94-95 gsr ecu. now, im planning on getting uberdata in a few weeks, but for now im not sure what to set the vafc at. ive been to

http://www.thedropshop.tv/vafc.htm

and i know what i would be setting it to, but how much farther should i drop it down to take out the extra .2 liters the ecu thinks i have? any advice to get me going a few weeks till i get myself set up with uberdata would be great. thanks.

WOOT WOOT

UPDATE

There were no settings on the AFC that would allow calibration for a 2 bar sensor. Oh well.

 

Saving this bad boy to my Watch Topics....
Might need some help after this weekend

 

Ok so I have a h22 turbo running 5psi on dsm 450's. I set all of my settings to -30% on my vafc2 and it runs pretty well except for I pull a 02 sensor code. Anyone know why this is happening. Im also getting horrible gas mileage... about 200miles on a cx tank

 

wow i jsut read about 18 pages of this afc hack lol.
now right i am runnin a b20z turbo with a revhard kit low boost about 7psi off the turbosmart wastegate.

i have my settings at idle to @ -40% like everyone says to do. and gradually richen it more while in boost correct?
right now imma runnin 440cc injectors w/ afc hack and eventually it goes to -32% on hi settings when in boost. now the a/f meter i dunno if i should even go by that. now i am running a open DP and people have told me that ***** with the readings on the a/f gauge and its reads weird with the fuel @ -34% during full boost and WOT it goes to lean real quick and then back to rich. i have been tryin to **** with it to stay rich on the gauge but no avail. should i even worry about what the gauge says? the car doesnt feel lean at all but it does break up a lil bit during boost(too much fuel up top) but other than that the afc hack runs right to liam for startin this thread like 2 years ago.

 

we have been running this setup for quite sometime here in Reno, actually i am in the process of running the hack on my setup.....
for the hack...

 

I am now one with my vafc....

 

how about this on a JRSC setup.....
i have a b16a2 with 8lbs JRSC and methanol/water injection and i just bough the VAFC.

 

I dont quite understand how the map sensor is connected, so you unscrew the sensor and screw it in where the TPS is supposed to go?

 

Nobody should be running this setup anymore...checkout uberdata! Its much better an idea.

so in order to this AFC hack all i need is a apexi SAFC OR VAFC? (thats it?)
ok so then i can also remove my fmu and install my RC 440's??
then mess with the settings a little??

need some more info

cheers

Yes. take out the FMU. take otu the missing links. install this and larger injectors and diel the settigns into the -30's to -40's and get it tuned. this way will work for fuel. but it does skew the ign timnig a crap load sicne you are messing with the laod that the ecu is thinknig the map sesnro is outputing. That's why ppl ahte HACk's so much. Detonation = kills head gaskets. Only way to safely run it is boost as HIGH as your map sensor allows. then retard your ditributor 2-3 degrees and you shall be okay. This is if you don't want to add any other timnig devices(which don't do jack much either to the hack method) and also if you don't wanna chip your ECU... I've ben running this setup for a while but with stock IGN base timing and I've also chipped my ECU to coutner the IGN advance issue and provide bosot retard. I think I'm ramblnig now...

 

if im going to get alot of detonation then i think sticking with my check valves and fmu is better isnt it?? safer...

 

How much are you boosting.

 

anywhere from 5-10psi

 

if you really wanna stick with FMU then it works, in its own unsafe scary way lol. Puts alot of stress on the inejctors. But if you do boost 10 psi.. I'd sue teh AFC IMO and retard base timing. This is all if you don't wanan chip your ecu to something like uberdata etc or get a real management system.

 

Just read the first few pages. How do you compensate for the advanced timing? (assuming you have to use AFC) Richer fuel mixture? Water/alcohol injection? Would you shoot for a richer a/f ratio like 10:1? Would an aftermarket knock sensor help during tuning? Thx.

 

ok i have i ls vtec turbo in a crx i am running the afc hack with the 450cc dsm injectors at 10 psi. i have two questions the 1st one is that i have my setting at -40% from 1000k to 4000k -35% at 5000k and -30% from 600 to 8000k
and when i reach about 6500k the car starts breaking down dont know if its detonationed or what. oh yeah my sensor type is set on hot wire with 1 in and 1 out is that right because when i put it on pressure with 6 in and 6 out it idles like ****. please help dont know what the sensor type should be on. the timing might not be advanced or something but when i turn the dizzy back to try and retard it the car backfires like crazy when i hit about 6k. sory for the long post but i have been searching for like a week know and cant seem to find any help.
