Finally installed xHP stage 2!

Glad to say the install process went as described in the manual. Took about 35 minute for the backup, then another 15 minutes for 'initial' flash.

Then stage 2 took about 4 minutes.

THere were various gongs and warning signs during the flashing process.

Took it for a 20 minute drive. Changes in D mode seem a little more forceful. Seemed more responsive to light throttle inputs. But it still didn't drop down a gear on light throttle, even up hill. Surprising as the car stayed in 6th gear even up a reasonably steep hill. Until I mashed the throttle, in which case it dropped to 3.

I like the display of gear number in all modes.

Haven't tried M mode yet.
