ow do I check my ecm to see if it is a 350 ecm
The writing on the box says
SERV. NO. 1227747
Suppose to be out of a Suburban 2wd 350 auto Can anyone tell me if this is right ?.. or a way to open it and read the chips to identify thanx
Get the Broadcast Number off of the EPROM. It is a four letter code similar to the one pictured below. The EPROM is the one with the light blue cover.
Knowing the broadcast code will help determine your question.
Re eprom 350 or not..
It has ADTR the small chip has
DELCO ADTR 3432
The other ECM I have here that may have got mixed up is
1227747 ACSU which comes up as a 350 tbi LO5 1990 chev van but I got it from an 88 suburban
