Hi guys
I am working to compile a E92 service number by year list, want to add OS# to this for future as a quick reference guide, as most of this genv global a stuff is year and model specific.
If anyone has any to add please post or send, I dont mind to make a compatibility list if anyone has tested,
E92 ECM Service Numbers
2014 ATS 12656993
2016 SIERRA 12662034
2016 SILVERADO 12672537
2016 SIERRA 12673195
Jake Hatfield
Central KY
2015 Silverado 12664769
2016 Silverado OS# 12672612
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I'm pretty new to this but would this list be more complete if the service number were associated to an OS number as well as engine/transmission combination?
Example: I have a 2016 with a service number 12664768. It is for a 5.3 with an 8 speed. The OS number is 12672612
This computer has not been run yet because it was purchased for a swap I'm going to be doing soon. I don't know for sure the service number actually had the current OS when it left the factory.
