Robert Korn asks about the id of an ECM he found in an auction box.
The 1227747 is the basic V6/V8 TBI truck ECM. It was used on everything from
2.8's to 7.4L engines. The EPROM in yours, ASDU 9567 is for a 1990, 5.7L
full size truck with automatic transmission. The main difference between
this ECM and the ones used by cars of the same period is that the trucks
don't sense inlet air temperature, while the cars do.
