Thanks Keith

Is the Morgan system speed sensitive, or is the level of assistance manually adjustable on a potentiometer?
Dave I feel it reduces with speed but with 185 section tyres it's difficult to tell as occasionally it cuts out (until I squeeze the big connector under the dash) I don't notice until I slow down considerably.
Dave, Keith's will most likely have the early version which was a properly developed outsourced component with speed sensor unit in the electronics, MMC then 'value engineered' and fell out with the supplier, the later version (read more basic) is what became the factory option fit approx 2016 onwards, later was std fit on 3.7 Roadsters as per Richard V6 and mine, & yes, I've made mine switchable
