I just got the VAFC control installed the other day. I am planning on taking it to get it dynoed tuned. When it is tuned, do I want it to run rich or even it out?? Where will the most power come out, when it is rich? Also, I want to get rid of the carbon shooting out from the back, so then I do not want it too rich? Also, I would like to save a little more gas as well, what would be the best thing to do?

Gas prices are too high for me to mess with it =(

tuning a vafc is about as easy as it comes. I could teach my girlfriend to do it if i had to. If you were in my area, i would dyno tune it for 100 dollars.

you want to be in the 13:1 area at full throttle and 14.7:1 at part throttle. Part throttle is going to be rather hard to make perfect due to the small range of adjustments that you can make.

Getting the a/f to what you want is about all you can do. If there is a dip in power at vtec crossover, you need to raise the vtec crossover rpm.

everyone and their mother is gonna tell you to ditch the vafc and go obd1. and the more i look into it, and almost the same price and you can do a sick tune.

it definitely has its perks. But there are some people who have no intentions to go beyond the basic i/h/e setups. A vafc will do just fine for that.

about how much is an obd1, and the converstion?? I am planning on doing more, but thats later on when I get money. I just try to do a little because of school and work...

wats the best v tec setting for H to L an L to H?
also wats the best shift point where all the power is at?
idk if it makes much difference, but I have intake, Exhaust and AEM power steering and Altenator Pulleys, no aftermarket headers

you need a dyno to figure out optimal vtec crossover and where your power is. DO NOT just start messing with your fuel without anything to monitor it.

So let me get it straight... Its easy to tune it or do you need a professional to do it?... Is installation going to be a problem for a noob like me as well?
