I'm led to believe that Adrian's trials with the ECU upgrade work is now standard on modern Roadsters. They were a LOT worse back then..!!!!

I completely agree on the flywheel front, with a lightened one it is very likely to perform more like an one off switch with the power, fine for a race car, but in a car that is already relatively light on the road I suspect it would become a difficult car to drive and possibly unpredictable for a less experienced driver. Maybe a step too far IMHO.
Dual mass flywheels are a relatively recent introduction - the cars I worked on in the 70/90 period never had one and werent any more difficult to drive.

TBH a 140 mile drive today to the Midlands on A roads with the top down was a pleasure as I wasn't dwelling on the negatives. Nevertheless will have a word with KH next week when car booked for first service.

Follow up from above. According to Dan at KH, Adrian's efforts led to the ARV6 mapping but did not filter down to Roadster production due to lack of emission compliance. This is born out in the fact that the admittedly useless fuel consumption bar graph display still works.

Very interesting info here. Someone presumably has had some input into retuning the variables, but I have no idea which outfit, or how deep they went.
I have high hopes for Dan coming up with a far better product for the future, Richard.
Thank you for the update.
Steve

Oh, I don't know.. I've spent many an unhappy hour attempting to tune a pair of carbs in, let alone a set of triple SU's..!
Plugging a laptop in is easy in comparison, except for the fact I have no idea what I'm doing..

They proved tricky to balance and were I'm told only fitted to allow the rally spec to run 3 Webers. Mine were fiddly to get right but have stayed in tune very well.
