To make the story short, the reason for my tcc not staying locked was a misadjusted cruise control brake switch that by the way inhibited cruise control function as well. I never noticed the cruise not working since i was doing all testing in city.
Hi all,
I have a 2000 Corvette and went from a LS6 78mm intake to a Fast 102 with 90mm TB (LS2).
After that change I noticed that 4th gear TCC operation was different than before. Now the TCC unlock at any speed as soon as I get below 14% throttle opening. I also had 3rd gear TCC enabled but now have a hard time to get it to work at all.
The only things that I changed from the old to the new tune were B4349 ETC Throttle Area conversion from .255 to .320 and of course the VE table .
Going back to the old values on B4349 didn't change the new behaviour.
I have an old log in which my car stayed locked with no throttle incl. DFCO and now a new log in which it unlocks anytime I get below 14% TP.
The base tune (COS5) was not changed.
Do you have any ideas on how to get the old behavior back since the constant unlocking and locking is really annoying.
I'll attach the logs and my current tune to see what I mean.
Thanks
Alex
