Not so much an update, but a new toy:
Innovate MTX-L:

Wide band O2 gauge and sensor with data logging (laptop connect with serial cable).
I know mines not fuelling right - the screw on the AFM was messed with before I got it. I should be able to tweak that with it a bit but its more peace of mind I'm after that it doesn't lean out at the top. It as suitable outputs to connect to after market ECU's like Megasquirt so that may be on the cards next...
