I should clarify. EWS delete was easy for a Siemens MS 43. I'm not sure on a Bosch ME 9.2.1
I ordered a DME with EWS deleted. Second, the EWS module wiring was fused to allow starter cranking. The two large EWS harness wires are connected together with a fuse.
This company can do it for a Bosch ME 9.2:

Their price is what I paid for a replacement DME with EWS deleted.
