I designed the EGO SIM myself.
You can see what it looks like in the membersí section - http://188.8.131.52/MembersList/Vi...30&PicNumber=4
The SIM will only work with o2 sensors that output in the standard 0V to 1V range (MY99, MY98 only, not sure about previous years).
I suppose I could sell them, but I have no experience. Iím not sure what such a device is worth.
