[quote=Peter J] It is on the steering at the 4 O/C position, just below the "up shift paddle and perfectly placed for a thumb press. Properly known as the Sport Response button it gives a 3psi overboost in turbocharged cars that lasts for roughly 20 seconds. It is perfect for making a pass and need just a little more power. In addition the revs will go to almost redline if your foot is kept planted on the accelerator pedal. The suspension will tighten to its firmest setting, the sport exhaust will open up and emit a louder sound and the engine mounts will also stiffen.
It apparently replaces the mechanical Rising Rate Fuel Pressure Regulator used on the classic Morgans,
though THEY certainly did not stiffen the suspension. 
RRFPRs provide as much as 1-15 psi more fuel pressure in demand situations. The UK also invented (FSE) many variants, so one can choose the demand pressure rise curve desired OR, with the earliest Morgan EFIs, adjust fuel pressure with a turn of dial road to suit any engine capacity or competion . I coupled my FSE with a fuel pressure gauge, (1) to know precisely how to tune the engine to meet different situations. 2. I found the gauge helpful as at any instant, one knows whether a problem is ignition or fuel related, cutting out 50% of the guess work. Do CX cars have a fuel pressure gauge? That would be brilliant!
Of course, with the system you describe, within its programmed parameters, there is no need of any owner intervention aside from flipping a switch. I am fascinated how brakes, cooling, virtually everything, is becoming computer controlled.
