Message reads: "may be a service PCM" & will not accept the program from the existing PCM.

You will probably have to flash back to an oem os using a tech 2 before it will allow you to do anything with it. It all depends on what program you are using.

Is there a code being set?
such as: "P0601 " ?

maybe the dealership has to set it up for you since it was remanned? After that you're probably good to go

Thanks for the comments. Dealership says they have no bench connector & no way to connect to the PCM if not mounted in the car. The tunner installed an OEM program despite the "may be a service PCM" message. After OEM intall, the PCM would not accept my existing file. I don't know if P0601 (memory error) code was set w/ message. Will ask the tuner on Monday.

More general information:

-PCM acquired from Pace performance through their supplier. Pace has not run into this type of issue w/any remanufactured PCM's. Although, they normally flash stock programs into remanufactured PCM's once mounted in the car.
-Tuner is experienced & is working out of a professional race shop that has been in business for over 30 years.
-Am not sure what program is being used. Any suggestions as to what could be done using LS1 edit or Hp2....etc.?

Currently, the plan is to get another PCM & try again. Am hoping suggestions here (LS1 tech) will lead to a solution that corrects the issue before the new PCM arrives.

Update:

The PCM is working. The PCM was mounted in the car & has accepted my custom program. Have no idea why it wouldn't accept my tune while on the bench.

As always; thank-you & your comments are always appreciated.
