ok my turn....
i just recently bought a 92 civic hb si with a jdm B16A w/greddy turbo kit. it came with a Vafc but the thing is that it has a GSR stock comp in it so how do i go by doing this mod? what kinda settings should i set it at? also it has a vortec FMU and im not sure what the rating on the injectors are but its sopose to be a greddy turbo kit for a GSR with GSR comp and has a very large FMIC. so please everyone your feed back and info will greaty be appreciated!!!

It doesnt "add" timing over what the normal honda ecu would do. There is under certian circumstances, normally at low rpm and in boost, where the honda ecu will advance the timing which is what you dont want to happened. However start with a retarted base timing and you shouldnt have a problem. There is hundreds of people on this board running this setup and love it.

it seems everyone who used this was on a turbo but if I'm to use if on the jrsc for the D16Y8... can I use the stock fuel pump and injectors? and what about the JR FMU? do I have to remove the FMU?....

stock fuel pump is good until about 5-6psi. If you really wanna use a stock pump i recommend getting a fuel pressure regulator and watch your fuel pressure under boost. If your loosing fuel pressure under boost you need a larger fuel pump.

Thanks for replying...
but isn't the jackson racing FMU the same at the fuel pump?
and did u ment having a fuel pressure gauge inside the car to see the pressure when under boost? coz I have a pressure gauge right on the fuel filter under the hood....

the JR FMU increases the fuel pressure per each PSI of boost. Its normally like a 12:1. So for each 1psi of boost the fuel pressure increases 12psi from the base of ~40psi. So for 6psi your talking 72psi ontop of the 40...~100+psi. Its hard on the fuel injectors, fuel pump, and everything else. Also all cars are different some need more fuel some need less. The 12:1 just dumps fuel. Going with the afc hack or hondata it worlds better.

is retarding the base timing by turning the distributor the same as setting the base timing to stock then using devices like apexi ITC to retard timing?
i'm using a jacob's boost timing master with the hack, i set the base timing to stock then retard about 4 degrees with the jacobs.

I dont understand how you retard timing and how much? plz liam elaborate on this, how do you do it manually and how many degrees? Will it damage the idle? Will problems from hot starts arise from this method? Thanks

You move the dizzy. Get a timing light, and adjust the distributor back and forth. With the timing light you can find out how many degrees advance or retarded you are from base.
The helms manual will help you with this more.

Yea i think you can use something like the ITC to adjust timing. But i think its a static adjust...not dynamic in boost like you want. So it would be useful to adjust the timing back to static if you were too lazy to turn the dizzy. hehe Or setting a retarded base timing on the fly from in the car.

Re: h-t afc hack info (liam821)
I don't understand why more people don't use an aftermarket chip with the AFC Hack. J. Davis who is on this board and PGFMI.com altered PR3 and PW0 programs to have 1 degree of timing retard for every pound of boost. Wouldn't this solve all the problems and complaints about the hack?

yea it would. but i have a p28 ecu obd1 so those wont help me any. It also costs more. By the time you add the price of the afc, new ecu, chip, etc etc you could just get a hondata.

Re: h-t afc hack info (liam821)
I have read all nine pages of this thread and i can definitely say that it has been very informative .However jus a few questions 
1. I have a 1993 B16a2 engine, would the settings described previously work with RC440 injectors with a t3/to4e set @ 7psi....
I have seen where most of the persons running this form of the hack are running btwn. 8-10psi...and was jus wondering if 7psi would result in a overly rich situation..
if anyone has this setup plz post your results......

The RC 440cc injectors would work great...as will the settings described.
And the neat thing about the hack - it will give the correct fuel for 2psi or 8psi or whatever you want. I passed california smog just fine with 450cc injectors and the afc hack (another no turbo of course). So i know the fuel delivery is great.

Re: h-t afc hack info (madeiniraq)
I read a thread about changing the inputs/output on the AFC to let us us a 3 bar GM map sensor. I can't find the thread ( in a desent amount of time ), but if we/I were to change the input/output ( IE: not 1:1 anymore, like 1:6 or something ), then could we turn the boost upto 15psi ?
The shorter question is... Is the honda map sensor the reason we can't run more than 10psi or is the map voltage getting too high after/at 10psi and making the CEL come on ?
I'd bet with some DSM 520cc injectors and -45/-50 across the board we could safly run 13-15psi, but the map sensor wouldn't go that high, hense the question about using the GM 3bar map sensor.
I like factory/getto stuff one my honda, I kinda like to show off the fact that it can be fast/cheap/getto/ and "low tech and still run with V8 cars...
I'll save my $1700 ( don't forget the wideband O2 sensor ) for the EMS on the stealth TT, not the 155K mile civic...
I have a chip that someone burnt for me using gettodyne for $15 shipped. It has:
1* retard per psi
fuel maps recurved for dsm 450cc's
7500 rpm rev limit ( I shift at 7K )
option for launch control ( but my clutch switch is jacked up )
Takes out the ecu throwing the code for seeing boost
All for $15.... The current limit is supposed to be 9psi b/c of the factory map sensor.
I see many OBD-1 to OBD-0 conversions in the future ( that's a joke, don't reply why thats wrong ).

There is people running more boost with a 3bar...but they normally they run like **** except for in boost since they tune for that. So off boost drivablity sucks. Doing the hack with the 2bar and -40% you hit the limit not because of the map but you hit the top of the fuel map in the honda ecu. (thats when you get a map CEL)

The honda map sensor is good until around 12psi normally. It sorta depends on the sensor. I have about 5-6 of them in my garage and some max out around 10psi and some around 12psi. You can wire up the map sensor to a volt meter and then a air compressor and check for yourself. But normally the limiting factor with the afc hack is you reach the top of the fuel map in the honda ecu.

Yes correct..if you could read that high with the honda map. The honda ecu doesnt like going more then -42% with the afc it starts idling ruff and running pretty bad in vacuum. WIth a -40% and in ~-20psi vacuum you are at the bottom of the honda fuel map....it just cant run a lower duty cycle for the injectors so you run rich.
The problem with using a 3bar is the honda ecu isnt calabrated to use it. The honda 2bar map sensor is 0-5 volts for -14.7psi -> 14.7psi (thats what a 2bar is). Well the 3bar also uses 0-5 volts but is from -14.7psi -> ~29. So the higher voltage you get the leaner the car is gonna run...so you end up having to tune for the top of the map so then your bottom end runs super rich. Its not a very good solution.

yeah it really ticks me off as that people always expect people like us to get a budget setup of only 7psi or so for extra 60whp and want us to buy a 1000 fuel system. jesus, some of us just want 7psi and that's it, not everyone is soooo damn interested in the 1/4 and with over 500whp... even when i have the money to build up the internals, the most i'm shooting for is 300whp, that's it, i don't care if i only can ran 13's or whatever, that's not what i want. the power is there for other usages, you don't see the nsx going to every 1/4 track in the world do you!!

Yes & No Majority of the people that buy a 1000 fuel system wants to have good gas mileage and get the most out of the system that they have setup...(Efficientcy) Also the hack is awseome but if you add up everything if you don't have the afc then you might as well do it right the first time.. Just my 2 cents... It's all about planing and how you really would like your car setup.. But if you look at the Greddy kits that run 6-7 psi they dump and waste fuel.... Edlebrock spent a lot more than $1000 to give a fuel system... I wonder if it dumps as much fuel as the Greddy/> ? Just makes you wander...
