This is not really a recommendation, but rather an observation:
If I were considering buying an Eluminator (I'm not), I would contact AEM to find out who that other company was, and I would be contacting Cascadia to see what they know about using their inverter with an Eluminator. There is at least one current (or recent) Cascadia employee who is (or has recently been) active in this forum - I would hope to hear from them when they see one of these discussions, and if it were me I might search earlier discussions for which member that might be.
The Eluminator is a drive unit from the Ford Mach-E, and is supplied by BorgWarner. Cascadia Motion is the division of BorgWarner which offers BorgWarner EV products to the aftermarket, and was created by the acquisition of a company which built motors using BorgWarner HVH cores (AM Racing) and a company which made inverters that were commonly used with those motors (Rinehart Motion Systems). The (formerly Rinehart) inverters from Cascadia are an obvious choice for any BorgWarner motor, and the (un-named) SEMA project illustrates that it does work... at least with the technical support that was provided to that project. Since that project has been done, the people at Cascadia presumably now know how to set up their inverter to run an Eluminator, even though it is not the inverter used in a Mach-E.AEM Electronics mentioned (as an aside in a YouTube video about an unrelated project) that an Eluminator installation which was at the SEMA show used a Cascadia inverter, borrowed from AEM's project.

They mentioned a team working with Ford, so although a consumer probably gets no information or support, a commercial operation building something for a show promoting Ford gets assistance.
