Blast from the past....

You're better off setting it at -35 across and going from there. Nobody is going to have a "perfect setting" on an AFC, especially from their car to yours. :-\

Thanks alot wojo!! I know no one is going to give me a perfect setting but it will help out to have a starting base. My setup is 91 civic, b18a1, 10 psi t3/t4, on dsm 450's, timming retarded 3 degrees.. wojo any 1/4 times or dyno #'s

Re: Whats your VAFC settings
 

You don't use someone elses tune as a "starting base," that's just asking for trouble. At the very least if you are going to start with his tune, richen it up EVERYWHERE and then tune from there.

Re: Whats your VAFC settings
 

Yea thats what I am going to do, Just richen up every rpm by like 5 and go from there cause I have a lm1 so I should be cool

Re: Whats your VAFC settings
 

Any other suggestions anyone????

Re: Whats your VAFC settings
 

CHIP THAT BITCH!!!! afc will own your ringlands!!!

Re: Whats your VAFC settings
 

the afc settings vary due to engine and injector size and boost and tons of other variables... you need to tune it to your engine, preferrably with a wideband

Re: Whats your VAFC settings
 

I said I have a wideband so it will get a somewhat good tune for now. I will be taking the car up to xenocron to get chipped and get a tune(how much $$$ xenocron).right after christmas.

194whp/ 176 trq no quarter mile times

Re: Whats your VAFC settings
 

Pretty nice hp!!!

Re: Whats your VAFC settings
 

why are you asking what to set it at if you have a wideband

set it to -35 and start the bitch up and go from there, the only good thing about the hack is that can alter the settings as you drive down the road, you'll have it tuned in about an hour

Re: Whats your VAFC settings
 

14.7 at cruise, light load
13.5 - 14.0 under a bit of load and acceleration conditions
13.0 at you cross the Vac/Boost threshhold...
12.0 - 12.5 in boost up to 5 psi
11.7 - 12.0 from 5 psi and up (to 10psi)

Is this good to go by?
what gear should I do the pulls in?

Re: Whats your VAFC settings
 

do the pulls in 3rd and 4th gear
and i think your a/f ratios are ok but a little conservative... it may be better to be conservative with a afc hack because of timing advance not sure though

Re: Whats your VAFC settings
 

thanks a lot anyone else????

this has the settings that you need for your hack assuming that you have 450s. otherwise go with the formula to calaculate afr for differant sized injectors.
