Anybody know the PN for the computer in an 87 1-ton 454 TBI?
Anybody know what the part number is for a computer in an 87 tbi 454 truck? Is it the same computer used on other tbi applications?

Yes, it is the same: 1227747. The PROM isn't the same though.

Thanks. My SES issue hasn't resurfaced, but I'm doing some homework just incase. I also wanted to find out if it was the same computer so I'd know if I already had the necessary chip burning software incase I ever decided to tinker.

If you wind up needing a new ECM -- I've got a spare 7747 that I know is in good shape
 You can have it dirt cheap
