1996 OS 16230171 Possibly LT1???

I read the file out of a 96 TA and it had 16230171 OS in it. Checking the VIN on tis2web this VIN should have had 16229933 OS.Checking quite a few 96 LT1 files I have and all the ones posted here I don't see 16230171 used in any of them. I'm pretty sure this PCM had the TA VIN put in it and that is why it was incorrect for this vehicle and not even sure is is a valid 96 OS. Does anyone have a 5.7L file that uses 16230171 or know what vehicle type and year it is a correct OS for?

I have nothing with that OS number but I have several different OBDII LT1 OS's.

I have a '97 with 16257678.
I have a '97 WS6 with 16258816.
I have a '97 Formula with 16236222.
I have a '96 Formula with 16230131.
I have a '96 with 16229995.
I have a '96 LT4 with 16229910.
I have a '96 Vette with 16229890.

Maybe the 9933 isn't the only gm cal available?





In searching for this I seem to remember some updated cals being released for some of the LT1's.
