I don't think I need anything for the F150, since I have an Explorer? Maybe I'm missing something, but for MY2013, I only see Diesel, Gasoline, HEV, and Fiesta. I didn't see a separate OBD manual for different gas engines. Looks like all the gas stuff is in one resource?
I'm not sure what I need yet, just gathering resources to assist in my plunge into the unknown (to me) world of Advantage III.
I assume one of the first things I'll need to figure out is updating my OE tune for a 3-bar MAP.If (when) I have further questions, I'll start a separate thread, so this one doesn't go off into the weeds. I have a feeling I'm about to become Artax in the Swamp of Sadness. LOL
I thought thats what you were after lol....ill email you some things later....but the transfer function is not what you need...you need to make sure you have calibrator level access...you may need to email or call sct
Go to speed density,scalar, and make the map slope and intercept values the same as TIP slope ans intercept
Its only 2 values that need changed for a 3 bar sensor

Sweet, thanks! I figured it might end up being some sort of copy/paste of TIP values. I'm still waiting on my dongle, so I'll check on the calibrator access when I get it in the mail, presumably some time this week.
Now, back to your regularly scheduled boost regulator discussion!
Didn't want to digress this thread anymore so i created a new post regarding access to the ObD manuals. any info is appreciated!

A snippit back on topic: Here is a screen grab of the log from the milti gear WOT pull I did last night.
Key for clarity:
Stair step in blue is gear
Mostly flat blue line is TIP desired
Magenta is TIP
Orange is MAP
The leftover blue line is Fuel Rail Pressure
Once we finish the revs to account for addition of these mods (possibly add a bit more boost) I'll post up some full logs.

Nice! I ended up at 14.5PSI, but my application required the 18.85PSI springs, otherwise the gate would hang open and my wastegate duty cycle would climb too high. I'm wondering if my springs were mismarked or out of tolerance. A spring preload adjuster on the Tial would be ideal.
Good luck with your fine tuning!
EDIT: I think I just came up with an idea for a preload adjuster, but it will probably take me a few days to work through the details.
Thought I would share this... this is a datalog from the wastegate setup on my car with an MBC along with Brad's tune.. Couple things to note...
1: The knock sensor is still wanting to add more timing through the whole run...
2: Common with his tunes I couldn't get traction until I hit 10mph...
3: This was a stand still launch at around 1700 rpm's...
4: I spun on the upshift from 1'st to 2nd gear...
5: The MAP sensor is reading more boost ALMOST through the whole run than what is commanded..
Not my best launch but look at how steady the fuel pressure is through the whole run along with the AFR's... also look at how flat that boost curve is through the gears..
With this tune I torched everyone from a stop light... vettes, srt's, mustangs, SS's, not much could touch me going 0-60..
Now that all being said.. one of these days I am going to create a thread with datalogs from Unleashed, LMS, and Brad so people can see the difference in how tuners approach tuning this cars... and the effect it has on them.

Well get it done already...I love some of the analytics you guys do it can really put things into perspective...Yeah these things are tough from a dig with the small turbos and awd
I've noticed that the 2010-12' SHO's have a little different boost logic and doesn't have the same scalars available in the tunes as the 2013+ cars but it's not a detriment at all.
And I also think the way you were manipulating the boost reference with your MBC was having an effect on your elevated boost but either way your car was strong

15.95 with the Yellow and Blue spring.

The MBC had some interesting effects... I believe.. and I think my logs prove it out, that if you take the time to dial it in with a the MBC, you can see good mid range torque increase by riding out those spikes at the shift just a little bit more than the WG by itself will allow... at the expense of fuel pressure of course.
But I spent quite a bit of time tuning that little bastard in there... run, datalog, adjust, repeat.... run, datalog, adjust, repeat... and you need to know how your car responds to lower temps.. so if you spike too hard on a tune that is not designed to handle those spikes you fuel pressure tanks.. or you can tighten the MBC all the way done effectively getting rid of the WG by not letting it open.. tried that... FRP dropped bellow 500 psi... afrs spiked.. stfts maxxed out.. car sh!t itself and closed the throttle to prevent the big bang... fun fun...
I think the MBC route is a nice option for a car that may need fine tuning between the spring combinations, or for eaking out just a bit more power BUT as mentioned for a DD type of car, I think it may be overkill. Would be a nice option for a race-tune type of setup.
Per AJP's request, I am swapping to the 15.95 spring pressure combo, and running a slightly higher E percentage than I have been running. I will keep the thread updated once I get the next set of logging done. This is partially also to see some more insight can be shed on the predicament that MiWiAu has with his spring combos

Woot. Looking forward to your results!
At some point, I'm also planning to catalog the free length, spring rates, and install preloads of the springs in my kit. Tial hasn't been very helpful in providing nominal values, but at least we'll have a single point of reference.
Also, FYI, I ordered some parts to MacGyver (or possibly MacGruber) a spring preload adjuster for the Tial, but it will take some time to receive everything. I also need to measure the internal clearances on the MV-S from the diaphragm to the bottom side of the cap to see how much room I have for my mechanism when the valve is open and springs are compressed.
What I'm thinking is making a preload adjuster that will thread in through the center cap threads and interface only with the small diameter gate spring.
Using the alternative spring chart I posted earlier, every single Tial pressure option has an alternate spring combo that utilizes a small diameter spring. If this works, it would allow you to alter the spring preload on the small spring to fine tune the cracking pressure without having to modify the boost reference with a MBC.
Of course, this will only be possible if there is sufficient clearance in the gate once the valve has been actuated and the springs don't sack out when additional preload is added...

But the thing is, is I can change target boost by whatever. A single KPA to get closer or further away from the spring rating of the Gate mod. So there really isn't a need for the MBC....Steal blue was using the MBC to make his own adjustments so he didn't have to bother me which he really wasn't lol
