Pcm code compatibility..

Hey gang. I'm looking to sell my DP Tuner F5 chip. My pcm code is an NVK3, will this same chip be compatible with a pcm code VDH5? Anyone know?

The chip is currently in my 99 f250 with pcm code NVK3. The guy that's interested has an 03 with pcm code VDH5. Wondering if it will work on his.

Run, drive, shift? Yes.

He'll have some lights on the dash that won't go out and the charging system might not work.

I'm curious... is tuning this difficult for a valid reason - tunes for one flavor of PCM not fully compatible with another? Or did Ford do it this way specifically to keep the tuner industry limited, either to protect IP, warranties, or minimize folks trashing the emissions quality and keep the EPA happy?

It just seems do unnecessarily complicated to me.
