Can anyone tell me which number is the mask for this eprom?

Post by n01tk »

New to the forum. Here are some images of my ECU and eprom.
The white tape over eprom window reads S131, 1618, 8020. The other side of the eprom also has a number 1345124. Thanks for any help.

1995 Chevy 3500
5.7L 4L80
16197427
