Pardon. But I am now a tad confused about this forum and its purpose as 'tuning' can be interpreted so widely (well, maybe just me). So may I ask what sorts of subjects are to be entertained here? A.K.A. Would a discussion of spark plugs be appropriate? Or do we limit the discussion to things not of a 'hardware' nature? just trying to understand the ground rules a bit better.
Thanks

^^^^^The "Tune" you get from the factory is a compromise between performance, emissions, and MPG, which of course are all related. It is not the best possible for MPG alone.....IMHO. I am sure it could be adjusted for MPG specifically.

Now whether a company could make any money off such a "Tune" is debatable. The Tune would have to be cost-effective. If it took 10 years of gas saving to pay for itself, I'm not interested. But if the gas savings were sufficient to pay for the thing in say 2-3 years....I am interested.

The word "Tune" as commonly used on this forum, relates to an ECU tuning program.....and is not particularly hardware related. That's the way I see it anyway.

Well to put simply I would agree with bluefront's statement above, its pertaining to ECU tuning, not actual hardware, like what plugs should I buy, or gap them too, etc. I would expect to see questions regarding changing things in your cars tune.

I am fine with that. [cool] Then my 'other' post about the Xcal2 is in the wrong spot and should be moved as its product related.

I'm glad there are people like Tom and others here who actually know specifics about tuning...I could only give an account about how the tuning of my car has helped MPG's and help make my Focus have better performance. Because of tuning my car at a reputable shop (DynoSpeed Racing) I have the advantage of going in and they always check out my car if something seems amiss. This should be a good Forum, if like it has been said dangerous and incorrect information doesn't bombard the forum...[clap]

I think that, overall, the tuning forum is going to be great. Yes, people will respond with answers that may not be correct, but how is that different than any other area of the discussion boards? I mean, that's the idea of forums: bounce ideas and gather info, is it not?

As far as causing damage, it will just have to be understood that any info on here is not guaranteed. It's not much different than taking advice from unqualified people that shouldn't answer engine (internal) questions or car audio questions.

As long as the forum is watched, I think it will be great. I know I've been wanting one for a while.

Can the xcal3 read a/f? If so, when I get mine from Tom I'd like to do this in order for Tom to be able to tweak it to make it just right.

you need to buy a wideband controller with a 5v output and input that to the x3, then set it up in livelink.

If my pre computer engine knowledge is still valid, increases in performance equate to increased efficiency thus increased MPG. The problem results from having 200 horsepower and using it all, all the time. If you drive with the same technique and the engine is more efficient MPG goes up.

I'll consider buying a "Tune", when a strictly fuel economy tune becomes available. . .
Since I haven't seen anything of the sort for the Focus..... perhaps such a "Tune" is not possible. [screwy]

YEAH, OR maybe because it's already pretty much "there" with the stock tune, you know, the "optimum compromise" between power and effeciency.

MPG. very beaten up topic around here especially the last couple years.

My view, on a scale of 1 - 10, all the tuning-tweek-tricks you can imagine combined ((short of extreme stuff like water injection, or (illegal) removing the CAT and retuning for that)) get's you between a 2 or 3 at best VERSUS, HOW you drive, being like a 7 or 8 in terms of mpg gain. There is no magic bullet trick or tune. Proper maintenance and drive like you don't care if you get there 5 minutes later. [^]

I dont agree , The ECU controles the amount of fuel used in idle and part throttle and it works so well that it does not need to be changed , there are a few things that will help MPG and in most cases are the same exact things that help performance

What makes for more performance is a more efficiant combustion this is also the same thing that helps MPG

Tom

S N A P.

It's like the old myth that 4 barrel Carbs used more gas than a 2 when just the opposite was true. More Power WAS there when you ASKED for it but by keeping a light foot on the gas, only the 2 (of 4) SMALLER barrels would open up, using fuel in easy running more effieceintly than a regular 2 barrel ("bbl"?) carb. I think a good tune is similar in that respect. SRI, same deal. More power when you need it, & more efficeincy all the time as long as you can resist the lure to romp on it.

im using my auto trans ecu to run my mtx swapped car, wrap your head around that one lol, the only difference is a few functions in the ecu that can be turned off

Absolutely true. The real "division", in terms of a TUNE impacting MPG isn't performance vice MPG, it's EMISSIONS vice MPG...

and all this engine tweeking is only going to effect MPG within a RELATIVELY narrow range anyway, (5 to at best 15%). Relative to what?

>You want to REALLY buttkick you mpg? Change your driving habbits. [werd] How you drive can impact MPG by as much as 40%. BUT That's from one extreme to the other. On average it's probably about 15-20% for most people.

With all the so-called mpg enhancers installed that claim big fuel savings, you have to stop every 100 miles or so, to siphon-off gas to keep it from spllling out of the overflow vent!

Seriously, give me an eco-boost turbo, or give me death! No, seriously, I want an eco-boost turbo now! My 2010 SES sedan needs SOMETHING!

Anything!

A sheep in wolf's clothing! An auto tranny! Oh, the pain!

It handles nicely, looks sharp...but where's the beef?

Is there any hope for this bolt-on bimbob?[???:)]

I need help with this tuning stuff....I'm getting my intake/exhaust done real soon so Im guessing a tune should follow...Ive heard mention about TurboToms tunes but can I get a legit one down locally? Would they even know how to tune a ST?
