[eeh1025]

I keep see if your cars tuned right, what is the proper was to tune your mustang, what do you do? is there one single thing to tune or more then one??
thanks

depending on the level of mods, people use dynos, TwEECers, and all that other high tech stuff i dont understand.
i can change a jet in a carb, but this computer stuff baffles me (i cant even figure out how to have an avitar. LOL).

If you're just talking about a stock mustang, a tune is simply cleaning/replacing plugs, wires, cap, rotor, air cleaner, fuel filter, and pcv valve then checking timing, tps, and idle.

If you've modified parts on your engine, then the tune might include adjusting fuel pressure (if you have and adjustable fuel pressure regulator), sometimes using a dyno along with adjusting the timing for max effiency.

If you added a chip to the brains of the EFI system, then it might include all the above and then modifying fuel mixture curves and engine control functions, also done on a dyno.

In your particular case my friend, My first suggestion would be to take an autoshop class and learn the basics. It will be much easier if you're familiar with some of the terminology and can assosiate parts with an actual function.

Good suggestion, you might also want to hook up with a local mustang club. Most members are more than willing to help a fellow stanger out showing him the way around the engine bay.

ok i got ya,
stockers need tune ups and
modified needs a little more,
i have a trick flow upper and lower intake
trick heads, mild cam, 75 TB, k&n cold air, hooker longtubes, flows, all msd eletrical, i have a timing control in the car so i can adjust it, and more stuff i cant think of
i just boguth a bbk fuel pressure gauge and regulator,
thats my problem now its running a bit rich, is it easy to install regulator and gause?
thank alot

I haven't installed a regulator, but I have installed a guage....mine is on the rail...is yours on the rail or are you getting one for inside the car? I had to buy a fitting from www.summitracing.com for around $8 to connect the guage to the rail. Take it from me..don't twist too hard and break the fitting off in the line...then you get to buy a new line and a new fitting too...not good. Use some good thread sealer/teflon tape on the fittings as well.

Simple to install. When you adjust the FPR make sure you unhook the vacuum line on top of the FPR. I would adjust it to about 38 psi as a baseline and then go from there. Good luck.

remember that adjusting FP is not gonna do a whole ton of good. the puter will adapt the a/f ratio down if you dial pressure up (via shortening the injector pulsewidth). the puter uses previous mapping and even data from recent WOT runs to adapt WOT operation. i personally dont get the AFPR idea as a means of messing with the a/f, but that is just me.


EEH, how do you know you are running rich? at what times do you run rich?

good luck.

mainly just at idle it smells real gasy, it may be because i dont have any cats or smog pump, or O2s, ill just get the FPR and gauge just to see how its running, should i set it at 38 to 40?
Thanks guys

um, with no cats or lambdas, you could run what would be considered lean and still smell fuel. people with everything but cats report smelling fuel - the unburnt fuel is not being catalyzed since there are no cats.
i would not make too many decisions based on the smell - atleast use a CO meter or some other means of checking the stoichiometry.
my two cents. good luck.

Yeah I have everything except my smog pump and cats including a less than a year old set of o2's and when it is cold outside I still get a faint gas smell first thing in the morning. ( And on a side note I feel better knowing I am not the only one that can't figure out the avatar thing)

I got ya,
so a FPR and guage should be pretty good for me now to se just how im running. it will be in the mail today.
thanks
