Two maintenance controllers report that during their discussion with an md-80 captain they were unaware that he also made a logbook entry about possible exceedances on both engines with EPR of 2.14 for 30 to 45 seconds during a windshear event. Aircraft was released with an open log write-up referencing the engine parameters and possible exceedances.

Narrative:
An md-80 aircraft flew into ZZZ. Dispatch had called and informed maintenance control of a possible windshear encounter in the flight. I believe engineering was left a message by a controller after the flight crew was questioned about an EPR setting of 2.14. Engineers were called back and used the dc-9 operating manual; performance -- takeoff 7; chart to analyze the reported observed 2.14 EPR and determined it was possible for a 2.14 EPR to be reached without exceeding engine speed limits. I relayed the information to a maintenance controller. No other information was given [other] than the EPR indication of 2.14 by the flight crew. At no time was I ever made aware that there was a pilot report made. If a pilot report had been entered into the flight log at ZZZ; it would have been addressed at that time.
