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.
