why are you locking out the mech and vac adv curves?
The trouble with welding the advance locked is getting the thing hot enough to get a good weld, without frying the module etc.
Much better to just bind the stripped down advance mechanism with two zip ties so it is locked fully advanced. Then reset the timing.
This is only required for motors with big racey cams that require full timing at idle. If you street drive it why are you locking out the vac advance.
You might want to limit the amount to avoid excessive vac advacne but no need to eliminate it.
Search my old posts for pictures that show various methods to locking out and limiting the mechanical and vac advance that don;t include welding and are reversable.
What cam is in this motor? locked out advance is not a cure all for every driving, idling issue.
