Hey!

My IAT readings are fine. But CLT stuck on 82c sometimes -17 if I change resistance manually.
0.4.4b (speeduino-202012release)
Car: Ford sierra Pinto engine
Please help! THX

I think mine said 82 until I connected it and calibrated it.
I take it yours is connected, so maybe the wrong board is selected?

[Marius222]

It is in 19pin wiring checked multiple times
Can it be software related?

[jonbill]

yes, I think the arduino pin for it might vary with the speeduino board, so you have to select the right speeduino board in tunerstudio.

[jonbill]

see "board layout" in Tunerstudio ->settings->engine constants

[Marius222]

No luck mate, it is set to Speeduino v0.4
Maybe ill try new project tomorrow and see if it helps.

[Marius222]

Btw car starts but still I need correct CLT readings

[jonbill]

And recent firmware? I think before 2 versions ago, you had to do calibrate->write to ECU.

Its all winter project for me. If I see update I take speeduino from car take back home and update. I did not use any other version before. Today was the first start of the car but CLT readings fail. Yesterday I installed speeduino-202012, today started the car. IDK what was the readings before the update

[jonbill]

No reason to think there's a problem with that firmware, I'm sure others would have spotted if it didn't read the CLT sensor.
I would guess there is a physical connection problem - the sensor is not connected to the arduino pin.
