Datalogging and tune revisions

So tell me if I have this straight. I have a tune from Torrie and was looking for some more performance via datalogging and submitting.  I went for a drive and emailed my first set of results to Torrie.  He sent me back a new tune within like 3 seconds and I loaded it on to my car.  Am I supposed to repeat this process several times for optimal results?  I hear of people sending Torrie like 10 datalogs and Im not sure why it would take so many to get a performance boost out of a tune but Im running a pretty basic setup. Tune and 3 bar.
 
Different driving environments, elevations, differences in cars, ect...

What works on one car doesn't always work on another. 
 
I'm on revision 22. (technically 23 as we went on a brief tangent)

I want my tune fast but at the same time I'd like it to be safe and live for a while.

Better safe than sorry IMHO.

From the remote tuners perspective they don't have your car sitting on a dyno, and coupled with unknown fuel quality (which varies wildly) and operating environment it demands a conservative approach IMHO.

 
Cool so do I just keep sending him an update everytime he sends me one?  When do I stop?  Im not savvy enough to read the datalogs and know what I need, and he doesnt really say much so Im just learning as I go lol!
 
Send Torrie updates when you feel you have settled into a rhythm with a revision, and still want to see if there's more, or something needs to be addressed, or both.  There's no time factor to ir.
 
I think it's kind of fun actually.  I'm on my 5th or 6th tune over the last few months.  I datalog whenever I get the chance.
 
So I finally put in a 3 bar map and got a tune from him for this.  After I ran it I datalogged the results for the first time and sent it in.  He sent me a revised one and I ran and datalogged that one too.  He said it was maxed out and possibly "dangerous" at lower temps (like below 60 degrees)....  Guess that ends my datalogging and revisions?  He told me to monitor fuel pressure and AFR to be sure, but Im not really sure what to do with that or what it means so I decided Ill just go back to the non datalogged 3 bar tune when it gets cooler out I suppose.

What kind of fuel do you run?

Im not sure what kind. Chevron? 711?  Costco?  whatever's close when im on E

That could be why you are done already.

I'd locate good top tier 93 and relog after a tank or two.

There is a huge difference in quality and knock resistance between top tier and non.

Of course if you have enough power then there's no need to do anything.

That would effectively make you the unicorn in the world of EBPF, lol
 
Yea I thought I had enough until I got beat by a beemer on the highway once!  So does top tier gas really make much difference?  My car gets it sometimes when I go to costco apparently

 
Yes and if you have E85 available you can do a little mixing and make it even more potent.

I'm running a E36 blend of Shell V-Power 93 and speedway E85 and I'm running about 12 degrees more spark advance than you at similar boost levels with less knock retard.

 
So I understand 93 is better than 87
I understand top tier is better than non
I know nothing about e85, e15, e34 and all of those things... 

Sorry for all the questions.  Im really looking for some easy tweaks.  Meth looks interesting but it also looks like a pain in the ass lol.  Thats why Im sticking with tune and datalogging for now.  And the 3 bar was cake to install so I got that too.

That's kind of leaving you hanging isn't it?...Aren't you paying because you aren't really the expert?


You want to post the log that he said you were maxxed out on and maybe we can steer you...I would say if fuel pressure gets below 1000 psi at any point that can be bad. If it gets below 1200-1400 that is borerline...If you are above 1500 psi then I wouldn't worry so much.

Your fuel pressure problems will be at the upshifts and especially the 2-3 Upshift.

I think a tuner has some obligation to protect people from themselves unless there is a clear understanding of the risks....But the risks have to be identified and perhaps that's part of the problem
