Grn92LX said:n/a PMS user here. Love it! Didn't get to do a full tune because I ended up pulling my motor to build a new combo. I bought it mostly to fix and tune my horrible idle. Fixed that in a day so it already paid for itself. Go to www.stangtuning.com tons of n/a PMS users there as well as blower/nitrous PMS guys. A wideband kit and a PMS and your set. Won't have to dyno a million times to fine tune the combo. IMO you'll get a better tune on the street since its a real load rather than a slow pull on the dyno in 4th gear. I gotta pick up a wideband so I can street tune my 347 once its running.

lxwants12 - If you have a reputable shop in your area they can tune your car nicely and can see what your car actually does when it is under part throttle or WOT...a chip to be burnt would be nice and they can simply reflash if you change the mods considerably...ideally I believe a dyno tune would be better if you have a nice shop to do it. PMS isn't the only way...check out the TwEECer (same concept...more in-depth)...
It is hard to tune by the seat of the pants...(PMS) but a dyno can show you what is truely going on...I'm not going to downplay the PMS to much in this one...but just realize the SOTP can be harder to distinguish than a dyno that "doesn't lie"...
Good Luck with your tuning choice...

Daggar said:I agree. So long as you can log data. I don't like the idea of having to "watch" the damned AFR meter while I'm haulin ass down the road. That's pretty ineffectual anyway.
Daggar said:Actually, with a WB02 that's capable of data logging, an RPM converter, and some patience, you can do very very well without a dyno tune. A lot of you are familiar with my SD/KB setup. When I installed it, there was no dyno (not as far as I knew anyway). Street tune was my only option. A few months later I managed to find a dyno pretty near me. The tune ended up being as good as it possibly good be for the size injectors I have installed (perfect across the power band and leaned out to the limit of the injectors up top). Not too shabby for a $400 WB02.
Grn92LX said:Point of THIS thread was who uses a PMS to tune a n/a combo. Not sure what 5spd GT is doing in the thread if he doesn't use a PMS on his n/a combo?
Grn92LX said:PMS (or any good tuning device) + a wideband = no need for a dyno end of story. Unless you wanna see what kinda #'s you put out (i could care less about rwhp as long as the a/f is good) A wideband and a street tune = MORE real world load rather than a slow pull in 1 gear. Your not tuning seat of the pants, your watching a wideband a/f meter and tuning as needed. A tuning device will tune part throttle way better because if your having issues, just make some minor changes until the issue is gone. Same thing with the idle. With a chip once the weather changes you are more than likely gonna need a retune for idle and power (HUGE inconvience and more $$) These EFI cars are weather tempermental once you modify them with h/c/i, injectors, mass air yada yada.
Grn92LX said:Point of the thread was about tuning a n/a combo with a PMS, NOTHING more NOTHING less
I guess your not to familiar with what a dyno does...much more controlled situation...I love how you describe it as "one slow pull in 1 gear"...1:1 ratio is why...
In the guys I know that have "chips" don't need a retune (neither do others that I have read) after the weather changes...that is a inaccurate argument and extrememly bias to "pro" the PMS. Inaccurate...how does the "stock one" do it? Mine acts good at 0* or 110* So if I get an aftermarket chip burnt to my car will it only act "good" at room temperature...lol...I think not
you put out horrible arguments. Not to much thought put into them IMO
My car isn't weather tempermental...nothing different than when I had stock MAF/injectors/heads/cam/intake...so I guess "these" cars isn't mine and some others...that is funny. I guess I got the "lucky" one
Grn92LX said:I'm very familiar with what a dyno does, plenty of pulls on my combo's both n/a and a hit (thats nitrous for you non racers) You ever go on one? The load on the dyno vs the load on the street/track is very different. Think david, think.
Common sense has to prevail here, lemme explain. Lets say you get your car chipped now when its spring time. All is running good and the a/f is good. Well, the colder months roll along and since your a daily driver I know you drive your stang in the winter. Well, you will run LEANER in the colder weather. I guess for a n/a combo like you, its not too big a deal, but you paid all that money for a chip and now all of a sudden the tune isn't 100% anymore. Kind of dangerous if your turbo'd or blown.
Apparently not if you don't see how weather effects a tune.
Again, go chip tune your car now and then make a few passes then make some passes in the middle of winter. You'll learn pretty quick. I have first hand experience with that at the track and cold weather
I'm sure you'll respnd to this, but i'm done and I won't be responding. Unless nate wants to take my place
