Is Your Car Tuned Correctly?

Both Greg and "That LaSota Guy" are pretty knowledgeable. ;-)
I have pretty much everything they have put out and all of it is worth while.
Yes they have and I welcome it.
You just added one more Bob! LOL!

Wow crazy how all the bad ass tuners are in here lol!!! I love it!
haha the Flyin Hawaiin has entered the building:rockon:
Bobcat's example for air model/camshaft?
The problem with the philosophy espoused here of tuning by moving accurate known MAF transfer functions is it is done as a matter of routine normal practice for every little modification.
Let’s take the example given of a cam upgrade and it’s relation to an accurate MAF. The new cam would have absolutely no affect on accurate MAF transfer functions. There are other parameters in the PCM that might need to be addressed but the MAF isn’t one of them. If the new cam did have an affect on the MAF in any way it tells me the meter curve was inaccurate from the start.
You guys want to depend the routine practice of moving known accurate MAF settings every time you tune go right ahead and we’ll continue to see more and more ill driving cars and even more blown engines like we’ve been seeing because of inaccurate meter curves which is especially crucial in these newer 2011’s and up vehicles.

Ford calibrators do indeed drive new prototypes for months in all driving conditions and temperatures. They do this not to calibrate the MAF transfer functions which they already calibrated to begin with but to address all kinds of real world situations like cold start-ups, hot starts,fuel mileage, drive-ability, etc. It’s mainly to make adjustments for drive-ability in all conditions.
I see your still sticking with this when even a real OEM calibrator steps in and gives his $02. LOL. Good luck with that argument.
I am certain Eric knows this and never meant that. What he was questioning was that the OP does this for EVERY TUNE???? Come on. I'm certain he does not spend that much time tuning every car. If that were the case then all tunes would cost thousands and thousands of dollars.
That is true, lots of time needed to perfect a tune, most tuners will spend 2-3 hours some less, and no its not cause they are some kind of god and they can do it just that fast, they just skip allot of it cause they have to move on to the next car and make money to survive. (especially for the tuners who charge a flat rate)
Most customers wont even notice, before I started tuning I remember taking my car to steve over at powertrain (imo the best tuner here in so cal) and I got charged 4 hours to tune my car I picked it up and asked him to perfect some other things he spent 2 hours and called me to tell me I have two hours into it do you want me to keep going? NO LOL! I knew the motor wasnt gonna blow up, I just had some cold start up issues. Since it was a cold only thing he would have to wait for it to sit over night again.
I know most customers look at it as a good thing when a tuner charges a flat rate but do you honestly think he is gonna keep tweeking the tune

In the example of a Cam upgrade one should modify the air flow model correctly to account for the change in VE throughout the Load / RPM band instead of relying on the MAF (better Eric? ;-) ). In this instance if the ONLY change was cams 'theoretically' one would not need to modify the MAF curve assuming proper engine airflow modeling, you are correct.
I don't think anyone is debating this?
And yes we all know there are some out there that tune strictly via MAF, but that is NOT the norm.
man, they will let anyone in here LOL
Get back to doing my dirty laundry Old Man.
:dancenana:
I am very well aware of the reason for it. My point was that just because Ford's calibration procedure is to do all of this testing, doesn't mean it that we have to follow the exact procedure Ford follows or else the result is a blown motor as some of the posts I've read in this thread would suggest.
This thread is misleading and was posted for the sole purpose drumming up business. PERIOD.
Having a flow bench derived MAF data for each car we tune would be great, but it is not feasible, nor cost effective, and definitely not something REQUIRED.
I mean absolutely no disrespect to Jimmy Larocca by saying this, but this information coming from someone selling "no tuning required" ETC throttle bodies :rollseyes seems a bit hypocritical to me. If tuning 100% properly is the main subject of discussion, then why isn't their flow data and Effective Throttle Area data supplied with the L&M throttle bodies?

Eric,
Mean no disrespect ? You saying something about post I didn't even write.
Yes I was interviewed for tech info and quoted but this is not my post.
Then you bring up a Throttle body that I haven't been involved with for 2 years making misleading statements.
I sold my shop 6 years ago and don't tune for the public.
If anybody is trying to drum up business here it might be you....
Trying talk to down facts about the preferred tuning method in favor of things you do which are less than optimal.
I’ll end it here since I see personal attacks.
Sorry you don’t like Ford’s preferred tuning methods.
Have a nice day.
I did in fact state right in the beginning of my article why I put this article together. This article was originally posted in the13’ Gt500 section because of all the tuning issues that members have expressed regarding their cars. It was moved here by the moderator. In case you missed it here is a direct quote below of my reason for writing it in the first place. I can’t say I’m surprised by your reaction to this article but my concern is for the community as a whole not those making money off them.
Quote:
“My reason for posting this information is my concern for the unsuspecting Mustang community, to hopefully educate because of what I see happening with member’s cars with aftermarket tunes.”
You really think its helping when saying if not done this way you will blow up you're engine and it will run like crap before it does?
