Lovely drive after reboot!

My Chim 4.0HC has had a completely flat battery for nearly 3 weeks due to a faulty immobiliser leaving the side lights on! Jump started with a battery pack. Engine fired first time and quickly despite being outside and sat through the recent snow etc. After leaving it to idle for a few mins to let it settle i took it for an hours drive to charge the battery etc. The engine has never been so good! Smooth, powerful and clean idling. Still a bit of hunting but....... Clearly the ECU resetting due to zero power has helped.
On the motorway temp gauge was 60 so a bit cool in the cabin though! Otherwise normally 70. Not brave enough to pop the roof off.....brrrrrr
