PROM Question
Is there a difference in the PROM chips in the '86-'89 ECM's (1227165)? I am asking because I got one cheap in a junkyard, but I don't know if it needs a different PROM or not.I see that the actual application for that ECM was quite varied.
Thanks!!
Thanks!!

There are some differences, such as 89 having VATS.

My main question though is:
Will I need a different PROM, if it is pre-89 and say....out of something with 6 cylinders instead of eight? If so can the PROMS be differentiated?
