B9KOS - You win the smug hat award!

It was exactly the same problem that you were having - the wires where they had been removed and replaced were being pushed out of the clip, and as such, the sensor was not being powered properly!

Lesson learnt.

Put in properly, and re-tested, and hey presto! All working fine!

Another lesson for all, if the Throttle switch aint working, the L8 defaults to 5v (ie WOT) This helps reduce engine damage in bad throttle situations!

Thats a bloody relief all things considered!

Now I may find out how efficient the closed loop system can be! I only hope that the over fuelling hasnt killed the brand spanking sensor!
