My project is a lot further along than the pics show, but I'm still in the beginning phases of the EFI install.
My first question has to do with the board's power supply and how it switches on the fuel pump. My stock isuzu wiring harness uses 2 fuel pump relays and a DPDT ecm relay. It seems for this setup to be preserved there must be a fuel pump "on" signal input to the ECM and I don't think MS works that way. In other words, are you guys using the architecture from the MS system shart for fuel pump and main board wiring or are you adapting your stock system's setup for the install?
I'm doing a lot of my wiring over again so it doesn't matter either way.
By the way the stock computer has been removed and the plan is to run all efi and spark functions through the megasquirt.
