Passed with flying colours (dealer tested).  Besides, the EZL is still in circuit when the EHA is disconnected, and the car runs fine (but not as fuel efficient or responsive as it could be).

Unless the EZL can influence the operation of the CIS-E.  As far as I'm aware, there is only one lead between the CIS-E and the EZL - the Full Load Input which comes from the Throttle Valve Switch.

Thanks,
Robert
