Adjustment 1 set: Kept the 1-2 shift at 30 mph, and raised the 2-3 shift to 60 mph across all shift modes. Raised the absolute fuel cutoff from 6700 rpm to 7000 rpm. TM adjusted to 25%.
Interestingly, with no change in shift points the 1-2 shift revved to 6600 rpm and hit a new higher calculated hp value.
Previously the 2-3 shift was commanded at 58 but happened at 60 mph. When I moved the commanded mph up to 60 mph it continued to be commanded at 60 mph. More testing needed there to understand.
I observe that the car is actually slowing down during shifts, perhaps due to engine braking in sport mode. I will plan to retest with the transmission in drive, which does not use engine braking, to see if that is advantageous.
Update: I see a source of delay in the 0-60 time — wheelspin after the 1-2 shift is a problem.

| Too much wheel spin after the 1-2 shift at 3 seconds is causing a false mph indicator for a spike to 55 mph after the shift. | |
| The 40-55 run in the middle is due to spinning tires. |
Reinstated TM and retested. Didn’t go WOT early enough in the retest to avoid the transmission shifting early 1-2 (shift commanded at 23 mph).
