I've been fighting some crazy clt readings. First they were super sketchy, spikes to 240F all the way to -26F. I changed out the parts store sensor with a Bosch (lh2.2 blue that grounds through 1 of the the wires) I had. It worked properly for a couple days then back to derpville. I was checking for continuity and opened up the pins on the microsquirt connector, so pulled out the pins and made them round again with some wire strippers and reinstalled. The gauge on tuner studio reads 180F constantly no matter if the sensor is connected if I short it with a piece of wire, nothing seems to change the reading. I do have 4.95 volts at the connector with the engine running. I also checked continuity in from the engine side connector to where the wires splice into the microsquirt loom. I'm at a loss, unless it's still not making a good connection to the microsquirt. Is there a setting that says to ignore the clt sensor somewhere that I inadvertantly clicked? I've also reloaded the firmware. What else can I check/do/test? Also reading the Bosch data sheet on the sensor it says it needs a pull-up resistor, but I've been running over a year without one. Is that what the bias resistor setting on the clt calibration page is for? Not clear in the documentation. I've also tried changing the polarity of the sensor wiring.
