[email protected] Posted April 17, 2022 Report Share Posted April 17, 2022 Hi there. Today I got up early and drove for 25min and 30 seconds. I live in Taranaki and I was driving way out in the country. At the time stated I came to a rural tunnel. It was long and dark. I reached for the headlights and turned them on. Instantly the engine cut out. I was still logging. I turned the lights off. Rolled backwards a few meters out of the tunnel cranked the motor with no success for the first attempt. Soon it started and I turned the lights on again and i completed the journey to home. Can you help me understand my log file? What caused the engine to stop? Why would the headlights do this. Everything is on a relay.Why does the log file say 37,000rpm and other crazy rpm amounts? Here is a link with: 1. The Log file. 2. The ECU tune file https://drive.google.com/drive/folders/1IltJ1ti2NTVznaOOgC695EcwBIsvunkh?usp=sharing As always a big thank you to all for your help. Kind Regards Rex Car is a Lotus 7. Engine is a Toyota 3sge Beams with ITB throttles. Ecu: Link G4+ Storm. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 18, 2022 Report Share Posted April 18, 2022 I think the initial cause was the trigger error which gave a large spike in RPM, the RPM limit then cut all fuel which stalled the engine. So the question is why did the headlights cause a trigger error... Really the only common circuit between headlights and trigger sensors is the ground so it would suggest there is a bad or intermittently bad ground somewhere which causes headlight current to pass through the ecu ground at times.
