After a recent engine/trans tune with a unsatisfactory experience I joined this site to fix the big issues with my trans. I followed the instructions on the site downloaded the 2010 CTSV6L90 MOD tune , copied over the trans portion and my car is 100 times better and I was so happy with the results/changes it immedietly made.
As I became familiar with HPT I decided to log my engine tune after reading that a good trans tune starts with a good engine tune. I see some very odd things and shortly after this last pull my 09 CTSV is only making 4 lbs of boost. I limped it home last night in hopes of finding some help here.
Points of interest in this log:
-MAP psi - I hope this is wrong I translated kpa to psi and my eyes popped out of my head
-The pull starts at frame 3000
-The 3-4 shift happens at about 6300K at frame 3187 is the delay flare?
-The 4-5 shift happens at 5500 rpm although the tps is at 84% ?? Frame 3309
As of last night I limped the car home only making 4 lbs boost according to the dash gauge. I did not pull any DTC's it was late and I was disappointed.
Any help is appreciated, Thank you
