Wrong engine code solved!

I looked at the dates of files in the EC3CL folder. These files were not updated to the date I programmed the EC3:
ECCL8.cof
ECCL8.map
ECCL8.O



So I started from scratch:

Unzipped the EC3CL folder.

Set ENG = A8; LS2COIL, LGSEC and WIDEBAND to 1 and rest to 0.

Did "Erase", "Clean" and "Build All" and "Program" in MPLAB and reinstalled chip for controller A.

Now EM3 correctly shows "A8" for engine code.

Changed to narrow band using mode 5, and EM3 display correctly changed from 16 to 12 for ENGINFO.

I must have chosen the "Make" option in MPLAB when I first programmed the chips, I guess.

Unfortunately I must have damaged the controller B CPU chip when handling it (MPLAB reports device ID = 0) and will have to order a new one.

Still waiting for the $1.79 shipped copper washers to arrive in mail. Maybe I should bite the bullet and order five (six) Stat-O-Seal washer/O-rings at $8.56 per pack of two. $25.68 total :(
