I am working on my "FBO" 2020 Mustang GT Base 10r80.
Base cars don't have drive mode so I attempted drag mode by specifying shift character of 2 across Sport/Track. The behavior I'm about to describe says otherwise, but now I'm thinking I may never get that setting in my non-drive mode car. So I may only have the three settings in the first row 'Normal' avaialable to me. The three columns 'Off/SST/LID' are described in the software as SST mode. I understand SST mode to be when you start paddling. Off would seem to be before you paddle. LID, I see some reference to 'Lever in Drive' but that doesn't actually pertain to SST mode (?)
The main line of inquiry I have is due to the fact that my first dyno made it clear that I was not achieving lockup on the dyno ( and thus likely getting 10-15hp low as measured.) I instructed the dyno owner to put selector in S and shift to 7th for the pull. I get the following percentages of actual speed compared to calculated theoretical full lockup from the dyno run:
RPM Calc Speed Actual Speed Ratio
3725 83.22305552 76.9 0.924
4670 104.3360186 96.2 0.922
5550 123.9967673 114.8 0.926
6257 139.7923915 130 0.930
6948 155.2305476 144.9 0.933
7160 159.9670007 149.5 0.935
7700 172.031551 163 0.948
On the street, I see what looks like a steady 97% ratio in one 3rd gear street log when in 'S' and about 98.5% ratio when in D, the latter based on several logs.
Is anyone able or willing to explain what parts of the shift character table I can utilize in my non-drive mode car?
What about whether shift character 1 or 2 is expected to not result in full lockup. My #s suggest perhaps a '2' is unlocked and '1' is half way to locked. If this is right, the tables that may control this certainly don't appear to be revealed to us.
Finally, is one able to make these cars dyno in D? Won't they always downshift on you or does pulling the dyno plug cause it not to do that?
My shift character tables, stock and tune are attached. Tune as of dyno attached. I have shift character maximum set to 2.
Thank you kindly.
