| Well some progress may have been made. After reading the link posted earlier the guy had exactly the same issues as me. Since I have changed I think every part on the bike I decided to take some resistance readings across the crank sensor and the spare one I used (don't know if it's relevant though). Both of them cold gave around 340 ohms and hot around 450 ohms.
Now compare this with a brand new one which started at around 450 ohms cold and went up to around 980 ohms when hot.
I figure like the guy in the link that the breaking down point of each sensor only kicked in when the bike got to around 180 degrees + hence my first track sessions being with out a problem. Once the sensor had got hot and spit the dummy out I don't think it recovered fully until it cooled again, which possible was not long enough in the 40 mins between sessions.
I'm hoping I had two duff sensors and the new one will prove my right tomorrow at Angelsey. Still taking an ECU wiring harness with me though. |
