Blown Mercruiser EMC Tuning

Does anyone know of an editor for the Mecruiser GM platform using the Delphi ECM4 control module?

I have setup a couple 502s's with Whipples and installed the necessary changes to accomodate the package. The guy I purchased it from also flashed the ECM's. However he will not disclosed the editor.

I would like to be able to data log the engines while in operation and make necessary monor changes and possibly incorporate broadband O2.

:cheers:
Any help would be appreciated
