Can the MSS54HP DME be flashed a similar way as the MS43 DME can? Can you ground pin 104 and put it into boot mode using flashing software? I'm interested in deleting my EWS. I opened my DME and it is laid out slightly different than an MS43 DME. Are there any sites the go over the process of flashing these DMEs? I'm interesting learning, more so than saving money buying a DME with EWS delete or sending it to someone so they can do it.
