I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

Ctsv 1-2 shift RPM overshoot

Hi Guys,

2009 Ctsv here running 2011 6L90 mod tune which has been tweaked overtime. I dont track it often but last time I did I was able to log it. My questions/observations are on the 1-2.

- The Shift commanded at 5k but did not complete until 6,400 - Why is this?

- The shift time shows 300ms which is not terrible and makes this even more odd though to me

Notes:

Car has 9.5 lower (12 psi), 1-7/8 headers, cooling mods

Running 20% TM

Car ran it's best ET on this run with 91 octane

Shift feel inside the car felt pretty good but higher gears felt even better

Screen shot can be seen here https://snag.gy/obxkgZ.jpg and log attached

Thanks in advance!
