please let me know my flaws,would like to get at least 19 lbs boost safely...using 93 octane....the scan was a little long a few full throttle passes when traffic allowed... one good 4x4 launch at about 14.36.36...about 14 lbs boost and stock converter stalled to 3621 rpm 82 degree day

Did you figure it out?
Airflow -> MAP -> MAP slope - did you change the sensor? It didn't seem to be the same setting as the 2015 in the repository
1872 Max Torque, increase this value
Driver Demand, copy over to Launch? unless you do all testing in D - not sure if Launch is your sport mode but it makes a difference. The SHO needed Sport and Drive tables increased
7147, Max Pressure, might want to try something like 32.5 first so it is limited to about 18 psi
1457 Torque Rate Limit, set to disable
16256, Upper Limit, change to all 10,000
The 2015-up Ford TC-1797 seems to be different from prior years with the throttle WOT start/stop. In the past it was set to 1023 so the driver demand table would not be ignored. So you can try changing them to 1023:
50119: 1023
50120: 1023
This way the Driver Demand table is used and the ECU makes all the necessary changes to throttle plate position, wastegate duty cycle, etc... on the fly

...any input will be appreciated...going to the drag strip today and see what it runs later today
I posted some notes. Download the version 1.2 guide from this forum (there are 3 parts) and see if any of that helps out. The 2015-up TC-1797 ECU is a bit different, so I'm curious to see what else I can add or change to that guide to help.
Also, try to datalog more parameters. I covered the bare minimum PIDs you should be logging in the datalogging guide:

ok...thank you for your suggestions I read through your guide there are quite a few differences between SHO and 2015 f150 3.5s ..and much thanks for your time and effort for that...don't think the wide open start stop will let me input 1023 though
launch was in drive
That's right, I forgot. 200 = 200%, not 1023 AD counts.
some reason 7147 max pressure is already abnormally high on the stock f-150 41.75psi and max torque stock is at 11,801 lb-ft of torque,map slope is stock unless I accidently entered somethingOriginally Posted by metroplex

I used the 2015 F-150 file from the repository, they must have a different calibration from the factory
How did you do at the track?

made some changes to last tune but did not get any extra boost...

That's pretty awesome
I know this is an old thread, but I was wondering if you've had any luck? Was there any difference launching in 4x2/2WD mode?
2wd would be useless too much tire spin...
So the tune is the same for 4x4 mode and 2WD mode? There aren't different driver demand or limiter tables?
