Great to hear from someone else who has had the ECU changed, I am hanging on to my ECU just in case. Your initial findings on the improved drivability are as mine, you can now be much more confident with the right foot and feeling you will be in control when changing up gear at higher revs. On open and quiet roads I can be a bit of a boot boy and before I had several rear end loss of traction due to the Rev hang or slight increase in revs, one which was very unpleasant as I was entering a bend. I would be very interested in your actual MPG figures from a measured fill up against a known mileage measured either on a map or gps. Prior to the final tweak my car was returning around 30mpg on general driving, but is now around 27-28 mpg. Considering the engine is putting out around 300bhp then 27-28 is probably not bad.
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.
