So after a weekend of jobs incl HID kit, front bumper repairs, front spoiler, skuttle panels etc I managed to get it all back together for a quick road test. Revs all working correctly (I will double check/compare with MES soon), however the speed is not quite right - I now know why!
Very simple - the scales are different, the ph3 max out at 180 mph, the ph2 max out at 160 mph. The distance between the 20 mph increments are marginally different. At 60 mph I had a gps speed of 52mph.
It must be the speed signal from the ABS that is different between a ph2 & 3. A real shame because they look excellent and I prefer the font. You can get a frequency changer to adjust the speed, usually used for different wheel sizes, I will have a look into it. Every day's a school day!
