Hello Alan,
As I said previously, I managed to install mine without removing any trim except the battery access cover. Very interested to see your photo, though, as having the monitoring module I'm still keen to find an easy way to pass its cable through into the rear of the cabin so as to have the monitoring module mounted inside the car. Would it have been possible to access the rear of the cabin with the boot/trunk linings out, do you think?
Regarding no difference in the actual operation of the gear/clutch, I think that in reality there never would be a difference unless the old F1 relay had been faulty, since the F1 pump is only run from time to time to keep the pressure up. I only really reported on the absence of any difference because I had read on some Ferrari forum someone who felt the Scud Ing system had improved things, but unless the old F1 relay was not passing enough current I don't see how this could be the case.
Tony
