Auto shift points on a Predator?
Has anyone adjusted the shift pressure points on predator on an auto? I know you can adjust shift pressure to speed up or slow down how long it takes to shift. Just wondering if anyone has had success with this after the performance tune? Any info would be appreciated. I also plan on getting it dyno tuned this weekend at Amazon Tuning Solutions located in Anderson, S.C. They have tuned several of my supercharged stangs. Thanks!

...from a prior post....
........................................ ....................
load the Performance Tune, then set
global rev limiter: 6200
shifting pressure (firmness) : +10%
shifting speed (quickness): -10%
timing: advance 3%
1-2; 2-3; 3-4 WOT shift RPM: 6000
1-2 WOT shift MPH: take your C5 A4 and place the gear selector in "1". Run the car up to 6000 and note the MPH at 6000 RPM. then enter the 1-2 WOT MPH shift @ 2mph below your finding.
2-3 shift MPH: take your C5 A4 and place the gear selector in "2". Run the car up to 6000 and note the MPH at 6000 RPM. then enter the 2-3 WOT MPH shift @ 2mph below your finding.
........................................ ...........
I started w/ this set-up, then I went to 6100 rev limit up, 6000 down
shift rpm: 5800
1-2 at 40 mph
2-3 at 75 mph
because the A4 won't upshift at WOT until both mph and rpm limits are reached...this way the low mph's are hit before the 5800 and the A4 upshifts arount 5800

Hey RR02Vette,
I have not had a duno tune yet as I'm not done with my mods. But if I understand correctly, a good tuner can do everything the Predator can do plus much more. Hopefully, someone with more knowledge with this will chime in.
