Good Morning,

I have a Rinda Diacom software and want to connect it to my Mercruiser 7.4 MPI 454 Engine from 1998 with a Delphi MEFI 3 - 16236999.

When I connect the cable I am asked to select the correct ECM. Which is the correct ECM for my Engine? The GM-Delco Marine EFI Mode 1 Master or something else?

Thanks in advance

Jezz
