im struggleing with the air and coolent temp sensors on my citreon, I have one wire going to the correct wire on the squirt and the other going to earth.
the readings in megatune go striaght up and dont change at all. Ive loaded the correct settings with easytherm and tried spare sensors but there is no change.

Re: coolent and air temp issue
Try grounding the sensor straight to the MS, and also check the sensor's resistance to make sure it is in spec.
Re: coolent and air temp issue
not sure what you mean by ground straight to ecu?

Re: coolent and air temp issue
Pins 17-19 on the DB37 are for sensor return. Instead of grounding the sensor on the chassis or engine block, run it back to the MS box.
Re: coolent and air temp issue
ground the coolent sensor to pin 19 and still the same
Re: coolent and air temp issue
i borrowed another ecu and its the same on that. Any pointers?
Re: coolent and air temp issue
sorted it, the bias resistor on the board is not the standard item so was way way of
Re: coolent and air temp issue
Hello Dave,
I am having the same issue with my microsquirt. For air temp, it's ok, but for coolant, it goes straight up and never moves. I don't understand what the bias resistor value is, and i don't know how to find it. Thanks for the help mate.
