The TQ Limiter logic is the same regardless of AEO or OEI.
It limits total Tq to 228% PI - Logically, that means 114%/114% max PI.
IF AEO, once you reach the 228 total, the Nr will droop since the EEC will not give more fuel to support Nf/Nr. TQ LIM does not "disengage".
If you go OEI, TQ LIM is still active but irrelevant. The good engine function still will give you your OEI limits.
Neither does it disengage if in OEI training. It is required in OEI training in the event of a condition (such as a real engine failure while in a low Nr condition) to prevent major engine/MGB overtorque while the EECs are pumping more fuel trying to recover the low Nr.
What does happen in OEI training is that OEI TRNG will automatically disengage under certain conditions, such as a real engine failure or a low Nr condition (<87%). The TQ LIM will still be engaged and prevent a potential overtorque until the pilot deselects it manually
