30% is probably too low. Put it at 40% and see if it better.

If you need the extra fuel, use a fpr.

 

do think i need a fpr with the walbro 255. if so what psi should i set it to

 

I assumed you felt you needed more fuel by backing down on the afc because that's what your doing when you stepped it down to 30%.

 

People still run the hack?

 

yeah i think i need more fuel but i am not to sure if it is fuel or timing i am going to get a timing gun tommorow and see where its at because when i try to retard it when i get in high rpms it stars breaking down and backfiring and i am also not sure if the sensor type setting is right because i have it on hot wire with 1in and 1out is this right?if not what does it need to be set on. is -30% enough torun 10psi or do i need it at -35% to not through a cel. i have a air fuel gauge and i know the are not all that accurate but when i get in high rpms it goes all the way into lean is that normal? so for so many ?'s but i have been messing with this for like 4 days now and it is pissing me off plus this is my 3rd motor and i dont want to blow it up. i am just trying to get everything done before sunday night cause i wanna smash this kis camaro ss. with this setup i should be able to run at least low 12's high 11's but it keeps breaking down in high rpms

ok you blew the previous two engines?
you want to make this one last?
you are going to race a camaro in a few days?
you don't exactly understand how the hack works and you still are going to use it?????
why??????????????????

 

i do understand the hack the problem was my timing was to far advanced i got a timing gun today and checked it and it was like 10 degrees advanced so i retarded it now it is driving fine. but i am still not sure what the sendor type should be on i am gonna try 6 in and 6 out tommorow and see what happens, that is the only thing i really dont understand is the sensor type if you could tell me i would be greatly appreciated i just dont know what that is exactly doing.

 

At this point in time no one should really be running this. I had a friend that just had his car street tuned on chromepro for 150bucks. That was by a "pro" tuner too. Its so much safer and yields so much more power than the hack. It was great for its time. I even ran the hack back in the day. But its time is over. There are MUCH safer and basically easier solutions.

 

yeah i know what your are saying i am going to go with TurboEdit i gues because my car is OBD0 but i just wanted to get this setup running right for now.

So no one should be running this hack anymore. Was it proven to be unsafe or is it outdated?

 

just read all post that jdavis made in this tread and in others about the hack and you will understand.

 

wow this is craziness

 

Hey liam wasupp man am question can I use 440 precision injector or just dsm 450?
and that s how u do it vafc 450dsm and fuel pump how about setting the vafc to
-40% low and high
And the one isaw here from 1-4k -35% something then 4k-something k then x% how do I know what percent to put in each rpm thanks

 

check my thread to see if i should run the vafc on my boosted lsvtec.

here comith the flame war.

 

so has anyone had any big reliability issues with this? how long have people been running this with no problems?

 

So what is a better system to use that is not going to break the bank???

 

For the price of a vafc, you can get a chipped ecu with a basemap.

Then if you want to get into the DIY craze, simply download crome for free & make modifications to your basemap...

IMO vafc is a waste of time & money when we have crome, uberdata etc....

there's nothing wrong with the hack when done right. i ran it for almost two years with no problems what-so-ever. made 257whp at 6.5psi. i did blew my ringlands tho... but not because of the hack, it was because of a faulty boost controller. spiked to over 11psi.

 

my my my, we sure have come along way

 

I Love The VAFC Hack.
