Hello "Plethora of Eco-Boosted Knowledge"!

I come humbly asking for your wisdom:
I'm fairly new to this whole 'forced induction' side of things ...ownership anyways.

It's all starting to come together, but I have some mod questions that I need help with the details. Mostly tuning related;

- MAP turbo system v. other styles; also, the relation of a 3 bar map, 4 bar map tunes, etc.

- Custom v. Out-of-the-Box tunes (ie. differences between generic tune, Unleashed, LMS, etc.

- tuning 'flash' devices - recommendations? OBDII scanners . iphone / wifi OBDII v. android / bluetooth OBDII

- different octane tunes ...is a 91, 93, etc. just a signifier for a higher performance tune...or does this have any actual correlation to the octane rating of the gas you should be using with these tunes.

Any info is good info. I'm sure most of this stuff is pretty simple, but when you're figuring it out on your own it can be tricky.

TIA Guys!

Map sensor reads manifold pressure, factory 2 bar can only read 14.5ish, 3 bar can read 30ish and 4 bar can read 45ish. It's 14.5037738 psi per bar BUT you must remove ambient pressure from the total, ambient pressure - http://en.wikipedia.org/wiki/Atmospheric_pressure
Example 3 bar = 14.503*3 = 45.309 - ambient pressure (curently 13.98psi in my house) = 31.329 available boost or manifold pressure left to be able to measure
Most anybody has ever ran is 26psi (me), most run around 21/22 on upgraded turbos and there's only a handfull of cars that have those. On stock turbos 17/18 and quickly drop down in the upper RPM due to small turbo size.
There was just a huge debate on the LMS vs Unleashed, I'd read that.
Flash devices - SCT and LMS devices, there may be others but they're not popular. Unleashed/Torrie uses SCT and LMS uses their own tuner
This car is a twin turbo high compression motor, I highly suggest running the highest octane you can all the time. Some or maybe even most will put in low octane gas but I just don't understand why you would do that. The pennies saved or even dollars per tank aren't worth it to me.
There's tons of info in the mods discussion as well, just FYI. http://www.ecoboostperformanceforum.com/index.php?topic=808.0

I read through the mods thread and thought it was all great info, just putting it all together now and needed some more details. The stuff you just added was perfect.
So if I'm running stock turbos I don't need to worry about the extra bars?

Always looking for more recommendations on devices, experience, and such.

If you're going to go "maxed out" a 3 bar will get you some more visibility into boost above 14.5ish, if you have 93 octane or want to run 100 octane or meth I highly suggest a 3 bar so you can tune for the additional boost you can run.

To answer question about MAP's cars come with a bar 2 MAP sensor which capable measuring pressure up 14.7psi. Bar is a unit of measurement of atmosphere pressure 1bar=14.7psi. Now you would a 2 bar MAP sensor would capable of reading up to 29.4psi and it is but you to factor in normal atmospheric pressure. So even normally aspirated engine has 14.7psi being force in.
As to recently some people found adding a bar 3 sensor and of course the car must be tuned for to run properly beneficial. Prior to this Bar 3's where only for those who had methanol injection.

Your question about tuning, I shouldn't touch this with a ten pole. As it much a heated debate. But I will try to give you the best unbiased description of both popular tuners.

Unleashed tuning offers tunes and fine tunes thru data logging, you plug in your tuning device and record set parameters and then you email to unleashed and they adjust and send new files.

LMS does not data log, LMS purchases shop vehicles and the do all development on there own vehicles.

There is much debate on this subject, in which tuning is most effective. But I am going to leave this for you to research the are many threads on such topic.

As for tuning devices, you will be limited to the device by whom does your tuning and which devices they support.

Different tunes for octane, not everyone through the country the same accessibility to 93 octane so tunes have to be tuned accordingly to what fuels are available.

Tuning:

Through my own research I have come to the conclusion that unleashed and LMS are both excellent choices as far as tuning your car. For me personally, the choice came down to location. Being in Chicago I can drive to LMS for a custom dyno tune to get the most out of my SHO.

2 bar vs. 3 bar map:

When going the meth and/or upgrades turbo's route, the 3 bar is a must. You can add a 3 bar without meth or upgraded turbo's, but you will need a tune for it. Stock turbo's run at about 12 psi (I believe). A good tube with the right mods will get you to 14 to 15 psi or above. A 3 bar is like $150. So I think it's worth the investment.

91 vs. 93:

The only reason there is an option for 91 octane gas is because 93 is not available to everyone. We get 93 here in Chicago, so I run a 93 octane tune. I used 93 even when on the stock tune.

Like you, I was also new to turbo cars when I bought my SHO. I was (still am) a hardcore mustang guy. But to be honest, I'm loving the turbos. I never thought I'd ever own a car with any less than 8 cylinders. I'm so much sold on the ecoboost platform, I'd seriously consider an ecoboost f-150. A truck with a V6, that's madness!  But I have learned a lot about my SHO. Mostly through this forum, and doing my own independent research using the information I found on this forum. Good luck.

Whats are you trying to achieve? Just a faster vehicle than stock?

Fair question.

At this point all I'm trying to achieve is knowledge.

Long-Term though...is a little more complicated.
I'm working towards the goal of making my truck not only stand out and look sharp, but also come as close to maximizing it's potential as a performance vehicle as can be achieved with a daily driver.

Also, I should add a special thanks to @SwampRat for his very informative phone call today!

Thanks for all the info!
First off, I think you did a great job at supplying a simple, straight forward, and un-biased, brief description of each major tuner. THANK YOU.
Secondly: I found the (recently closed)thread that you were referencing regarding why you shouldn't touch that topic with a ten foot pole. ...I must say, around page 5, I really got a kick out of the fact that thread was started with the title "Simple Question".
