Delete it, No WUR exists in the CIS-E arrangement so the FrankenCIS eWUR does not apply to CIS-E installs

you will require the FrankenCIS DPR interface though to properly control the DPR/EHA valve on the side of the CIS-E fuel head
VW/Audi call it a DPR - Differential Pressure Regulator
Mercedes refers to it as an EHA - Electro Hydraulic Actuator
VW units are grey and Mercedes are black, the electrical connections
are also different, VW use a standard Bosch EV1 style injector plug 
and Mercedes have a two round pin keyed connector 
The valve is basically a metal plate inside an electro-magnet and driven by a variable current rather than the usual injector pulses. The internal preload is offset to require between 10mA and 30mA of positive drive at idle. The DPR/EHA valve reverses current to close against the internal spring preload and system fuel pressure when commanded to lean out the mixture and/or go into fuel cut.

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS
