Right
This is the course of action I am going to take
Replace the crankshaft sensor, ..I have my eyes on one off an 05 bike, its £30 delivered small change in the bigger scope of things.
Having studying the HISS document I was forwarded and seeing how we fooled the HISS on another bike I have a sneaky feeling that it may be the culprit. On all of the components on the ignition side its the easiest item to change.
When you read how the hiss works and the time frame that it does its business it could well be the culprit.
I am also starting to wonder if we are putting too much emphasis on the temperature related issue.
On Sunday morning we swapped the ecm onto Eric's bike, Eric's ran fine. After Eric departed put mine back together, started and it ran for longer than its done for ages, the temp was up and down from 103 to 98 as the fan kicked on and off and then it cut out.
Please feel free to shoot me down in flames as I'm an engineer by trade and bloody electronics are not my strong point..
Eric the Semtex option is still on the table..
