As above.

Not going to be a firmware bug.

Will most likely be a hardware issue (wiring, sensor or faulty Speeduino/Arduino).

One other possibility is corrupted firmware.

You could do an eeprom clear and reload firmware then base tune then re-enter all your settings.

Today I checked the wiring and tested the sensor, everything is fine.
How do I reload the firmware?
I tried speedyloader ant installed downgrade and no luck for me

[Marius222]

Any other suggestions guys?

this might help with clearing the eeprom:

and the wiki explains how to load a firmware with speedyloader and load a base tune.
does your clt read with a base tune?

[Marius222]

Thx for quick response, ill check it other day

[Marius222]

No luck for me. Can I use sender(1wire) instead of sensor(2wires)?

[jonbill]

you can, but it wont make any difference if the signal isn't getting to the Arduino pin.

Once again as above.

You need to find and fix your actual problem.

Do you have a spare Arduino you can test?

Or some random resistors you can put in place of your sensor to see the result?

[Marius222]

Sender(1wire) works fine. But the sensor not. Although its new.. Okey so i stick to sender for now. Thanks for the tips guys!

[jonbill]

Maybe your sensor ground wasn't connected to a speeduino ground pin.
