Now that would boost sales...IMO

The programming of the eprom will be done with the romulator which mounts on top of ...

remove RP17 and RP18
replace RP18 with a jumper wire

that should be it.

you sure that's the part number on the ecm?

123 part = engine code

5 part = Auto or Manual (Auto = 5; Manual = 0)
6 part = CKT board type
