Try doing a reset with your transformer. 1 whistle and 5 bells, it should then confirm it per the manual.

Most likely because the engine isn't set to Factory values, as required for use with the DCS Remote Commander.

From page 204 of The DCS Companion 3rd Edition:

DCS Engine Reset to Factory Defaults

All DCS engines come from the factory with a DCS ID# that is correct for use with the DCS Remote Commander. If for any reason a DCS engine's DCS ID# changes to any other value, that engine will no longer be able to be operated by the DCS Remote Commander. In order for the engine to once again operate with the DCS Remote Commander, the engine must be reset to its factory default values. For an explanation of exactly how DCS ID#'s are assigned, refer to Appendix E: The Truth About DCS Engine ID Numbers, later in this book.

Newer PS3 engines, manufactured starting in 2014, may have the capability to perform a Factory Reset through a combination of button presses (SND, DIR, -). This is made possible by revised firmware in newer (2014) PS3 engines.

Otherwise, a DCS engine cannot be reset to its factory default values using the DCS Remote Commander. A Factory Reset command must address the engine by its actual DCS ID#, which a DCS Remote Commander, which is a one-way communications device, can never discover. Further, while a transformer reset, in conventional mode, will return almost all of the engine's values to their factory settings, it will not reset the engine's DCS ID#. It is necessary to use a either a DCS Remote and TIU, or a DCS Commander, to reset all of a DCS engine's settings to their factory defaults, including the engine's DCS ID#.

This and a whole lot more about DCS is all in MTH’s “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at MTH's web store!
