EGT TEMPERATURE

[KnightJDM]

good evening I have a problem with my EGT probe. I mounted it on the hottest point of the exhaust but the temperature remains at a fixed 612° and at high engine load it reaches a maximum of 620°.
What could it be?
Thanks.
I have already calibrated it several times from the PC.-

Please check:
1. if you have full range of measurement - disconnect TC+ and TC- and it should display around 1250C. If it's still 6xx C you have problem with to low power supply for EGT-K amplifier which is limiting output
2. please check thermocouple connection if it's not swapped, green should be positive and white should be negative
