Auto-diag different with new EPROM

Hi,

Can some body explain to me :

I have a Sapphire 2 wd.
With standard ECU (L1), it run perfectly.
I checked with auto-diag system : no default code.

I fitted new ECU (L1) with EPROM stage 1 and 31 actuator : it run perfectly
(255 hp with 1.1 bar_16 psi)
I checked with auto-diag : I obtain code 22 ( air sensor wire cutted )
I refitted standard ECU : no default code on auto-diag.

How is it possible ? Some idea ?

Thanks by advance.

Poor programming of the chip.
The ecu overboost errors are still present id say.

The above is only relevant if she flags the code after 14psi is reached.
