I can't seem to get the converter to lock in any gear but 4th unless I lock it manually with the switch. But once it locks in 4th I can click overdrive off and it will downshift to 3 and keep converter locked. I'm sure there is something I'm overlooking in the tuning software
Do you have your unlock tables higher then your lock tables ?
Also. With my pcs I have a parameter that no matter how early I command lockup in any gear I can set it so it won't allow lockup past the gear I've designated.
Other thing is your lock up table. If you command lockup after a shift point at given TPS it could cause issues
Hmm sounds like the pcs has some more tuning adjustments. I can tune the shift points really well throughout the tps range but the converter settings seem kind of vague
