What is the stock chip set number? There is a good chance that I can post it.

On the chip first line 4231 second line 1618 third line 8020. On the blue part of memcal delco 3480 bnkm. On resistor pack 134420. Black part base of memcal 68767 94220 3
Also i would like to know if the memcals interchange if the ecm # is the same. Example being i have 3 of the 16197427 ecms 2 of these are bnkm letters on memcal and one is bjyl can these memcals be interchanged? I only ask because i have so many ecms.
BNKM is $31, see attached.
BJLY is $OD which is for the 4L60E.
$OE and $31 are for the 4L80E.
It should be OK to use BNKM with the 16197427 PCM.

THANK YOU, I didnt get home til real late today so i will try to load all these new into the truck tomorrow. i did play around with the fuel tables a little while i had emulation working with the other ecm. i know this setup needs about 15 to 20% more fuel in the main table but how do i add to the "pump shot" carb term i know but i got a dead spot when i hit the throttle at 1200 it falls flat unless i ease into it. i know when i do carbs i adjust the throttle lever cams to time the shot and i usually got o a 50 cc accelerator pump when i get a stock carb to modify it for race use i just dont know how to do this in the electronics yet lol.
Acceleration Enrichment = Pump Shot
the new bins you sent me work thank you. im gonnna try tuning a bit and data logging some. its running a bit better now but i think the timing table is gonna need a tweak too. not sure how to do that yet. also on bpw which table do i adjust to get more fuel off idle?
well it nkinda runs like real garbage trying to drive down the road. barely will go 20 mph.
