dyno tunning?????

[dealz]

ok ive been wanting to dyno my car for a while now just to see what my car is pushing but ppl tell me dyno places tune your car for you as well, i looked up prices and they charge a bit extra if they tune your car. What would dyno tunning do for my car or what would they do to tune my car i have no afc, no dsm link, no ems or anything i have

Faze 0-35 psi boost guage on the inside
A Manual Boost Controller
Big 16G turbo
ported Evo 3 exhaust mani
apexi 3' turbo back exhaust
And now an ACT street disk w/xtreme PP
fidanza flywheel

i really dont see what they could do to tune my car.

there is nothing to tune except maybe raise and lower boost. The only benifit you would get from a dyno run would be knowing how much hp you got.

thats what i thought, now on the other hand if i get an afc then dyno tunning would optimize the use of my afc right or wrong?

You are correct about both points. I would recommend that you get some sort of fuel management for your setup unless you only plan on running minimum boost pressures. Also you might want to consider getting a boost gauge that reads vacuum as well.

Just my .02

ya, basically getting your car tuned on a dyno is benificial for 2 reasons. One because they log your exact air/fuel and can tune for an exact air fuel ratio and two because they can see if what they did increased hp or not. So if you got some bigger injectors and a safc they could tune it for ya and you would get the most out of your setup but you can tune just as good as they can if you got a datalogger and a wideband setup. Dyno tuning can be very expensive and chances are one session would pay for a wideband sensor but that means you'd have to do it on your own and you wouldent get to see your hp unless you got a g-tech or something.

PLEASE don't pay them to tune with the s-afc when you get it. I was raped $100 an hour in addition to a $75 hook up fee by this retarded shop that did nothing but hit a target a/f ratio that I requested and raised the boost to what I told him. I wanted to kill someone when I saw the $230 bill. You could teach your little sister to do that on an AFC in a matter of minutes.

Watch your a/f on the dynojet readout. Add or remove fuel at the right rpm points on the AFC to get it where you want. When its all smoothed out, you can begin by leaning or richening it across the board to see what happens to the torque curve. Most dyno operators have seen it all and will give you tips and suggestions if you press them. Go with what works and keep the a/f at or below 11.5 on 93 octane and well below with 91 octane. ...that's IMO of course....

yeah my guage does read vaccum as well, i think ill invest in a afc and fuel upgrades first, my car gets a fuel cut off around 20 psi..

i dont know squat about an afc or tuning it but i guess i can learn a little when i get it

If you can turn on your computer, connect to the internet, and successfully make a post on this site (which I see you can), then using an AFC is child's play. Its nothing more than adjusting bars representing RPM points up and down with a little joystick and twist nob to scroll between them.
