Default ECM Part Number

Anyone know the part number for a 1995 LT1 EMC?

My 95 is in the need of a new ECM. When starting the car all systems will work and all is great but once it has reached operating temperatures and is shut off and restarted the EMC turns off the ASR and the A/C controls go crazy.

I can drive the car all day with no issues as long as you don't shut it off and try to restart.

PCM

1994-1995 #16188051 5.7L LT1 OBD1
1996-1997 #16214399 5.7L LT1/LT4 OBD2

All LTX PCM's are the same; only the tune programmed inside determined the application

The controller would remain unchanged through 1995 and was recognized with the service code 16188051.

The '94-'95 LT1 Corvettes used essentially the same PCM, but with one additional microchip to begin OBD-II-like communications.
The Vette controller used service code 16181333."
