Can't think of any good reason why the flash would be necessary on a car without EDC???

Speaking of installing these on a car with passive suspension...anyone have any feedback on the before/after? Seems like many (most) have these on cars with EDC.
In principle no, there’s no need to upgrade software on a non-EDC car.

MP-HAS were specifically designed for the EDC dampers. I recall reading folks that reported installing them on non-EDC with satisfactory results. However, as others have pointed out, if you’re going through the trouble, might as well get full coil overs and have the dampers matched to the springs.
