1998 TransAm converter lockup temperature

Hi all. 2 questions

1. Right now I have no lockup until the transmission reaches 68 degrees F. With a 3600 converter this makes the first several minutes of highway driving suck big time. Where can I lower this value to maybe around 40 degrees or so. No other car ive ever owned had this issue.

2. Lately Ive noticed that when going to write even just the calibration only, it says in the box "brickable" and that im tuning at my own risk. Tried a fresh read on the new update and then to write the file but same thing.

Thank you.

Post the file?
