While going for a drive today I figured out why my converter isn't locking. (Keep in mind my check engine light has been flashing only while driving but I didn't think much of it since everything sounds and feels fine). I was scanning while driving and deleted the code P0443 and the check engine light went off and the converter locked up. It drove nicely for a few seconds then the converter unlocked and the light came back on. I done that a few times to confirm that was the issue. I went to Autozone and picked up a new purge canister only to get home and remember I done away with that when I swapped over to the L92/L76 combo years ago :online2long:. Any way you could help me tune this out??

Set B0501 and B0502 to max value.

In C6001 set these DTC's to Not-Reported:
P0440
P0442
P0443
P0446
P0449
P1441
( actually, set all of P044 x and P144x to Not-Reported )

In C6002 leave those DTC's set to MIL.

I went ahead and set it along with all the others you mentioned to Not Reported. Thanks Joe, you've been a tremendous help!!
