The potentiometer that was taped up in the harness in the first few EZ Electric kits was non-functional. In the case of the EZ kits, you can either have the amount of assist varied by a potentiometer or you can have it varied by speed, via a VSS, but you can't have both. With the EZ kit, even at full assist (parking lot speeds), the steering cannot be described as light. It's about the same as a new BMW or Porsche. By about 40 mph it just feels like your old manual steering. If you're not happy with the level of assist, EZ can adjust it for you, by supplying new firmware for the unit's ECU.
How do you install that firmware into the ECU? Is there an input port on it?
Well. I drove a new Cayman and the steering was just right, I didn't even think about it. As a matter of fact, I'd have to read the specs to see if it even had power assist? I was busy being amazed at the PK or is that a PDK transmission?
I'm thinking that the EZ system sourced a unit from another vehicle that I'm not even aware of yet? I'm presuming they modified the one of the US sourced units from a GM. The components such as the motor and brain I think are the same but theirs has got the small hinged mounting seen on the Toyota, not the GM and the casting puts the motor up to the left at about 45 degrees in relationship to that.
The GM can be modified but was wondering if the EZ is sourced out of a Euro vehicle?
