ECU - MAP or AFM version?

[Knudsen]

Okay, i thought i had it all figured out.. Just untill i desided to disassembel my 2 spare ECU´s... The one one the left has a raised limiter and is the one we "know" is for a MAP engine. I talked to the guy i bought it from and his car WAS a mapped version. (The raised limiter was the primary reason to disasemble them cuz ive been asked, if i could raise the limiter in some stock ECU´s)
The one on the right is the one that EPC has 2 results from and says that it comes from a RHD car... Again the seller says its from a danish LHD car with the MAP engine.

As the picture shows, the 2 ECU´s is completly different

Is the only way to discover if they both are for a MAP version, to install them one by one? And if "yes" whats the risks?? ( I mean, if it shows that one of them is for an AFM - do i kill my engine?)
