Jonte Posted April 9, 2019 Report Share Posted April 9, 2019 Hi everyone! I really need some help! I can’t get any trigger signal on my lm7 engine. See trigger scope. Feeding the sensors with 8 volt but still no result. Any ideas? thanks! Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 10, 2019 Report Share Posted April 10, 2019 Hi Jonte, That 3V showing on trigger 2 of the scope seems a bit odd. I would expect it to either be near 4-5V (ecu pull up) or near 8V (if sensor has internal pullup). 3V suggests you may have the sensor pinout wrong. Im not very familiar with the LM7 engine - does it have the grey or black hall sensors like an LSx? Quote Link to comment Share on other sites More sharing options...
Jonte Posted April 11, 2019 Author Report Share Posted April 11, 2019 The sensor is black Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 12, 2019 Report Share Posted April 12, 2019 Ok, black sensors would suggest you have a "24X" engine. Can you confirm your sensors are wired like below. These pictures are looking into the sensor body. Quote Link to comment Share on other sites More sharing options...
