8HP70 TCC Lockup for Launch
Has anyone experimented with adjusting converter lock up for launch at the track?
I run in Track mode and my street data shows that Track will shift faster than Sport mode.
However, Track mode goes into Converter lock / overlock at around 1200 rpms in 1st gear.
At a recent track outing... my car 60'd in 1.59; however it didn't hit the tires hard at all. I launched it around 1600 rpm's.
I've been told Sport mode is faster, so this has to be due to TCC settings. Sport mode prevents Overlock all together, so there is likely some slippage.
I'm looking at disabling lockup all together in 1st gear or at least well past 60 ft RPM.
Thoughts? I know converter lockup reduces heat and improve longevity, however it is at the expense of torque multiplication.
