Re: Will the 05 HESD work on a 01 929?
The HESD is controlled by the ECU from a number of engine sensors.
It _may_ work as a damper but it certainly won't work as a HESD with automatic adjustability to conditions.
I believe at low speeds it opens a valve which pretty much shuts the damper off so I would expect at the very least you would have to modify that valve to stay closed since you won't have the signal from the ECU to tell it what speed you're doing.
