Scanning an unknown ECM
I'm doing a cummins swap in a 2007 GMC T7500 with the 7.8L Isusu/Duramax L6. I'm not getting a tach reading on the dash and was hoping to be able to connect to the ECM with efi to diagnose. Is there any chance of this? Here's a photo of the ECM, matbe there's a comapatible one in the list or a trick or two to make it work!
Just a little update, I can connect to the ECM with Auto Enginuity if I tell AE that it is a 2003 with a LB7, and I can read PIDs from that, but I'd still like to get into this ECM somehow with EFI so I can disable some DTCs and keep the CEL off with the cummins in there.
