The egt can't read anything below around 800-1000 accurately f if I recall correctly. I don't recall exactly, but it's several hundred degrees, maybe as low as 180 or so when the engine is ambient- around 50 today.

Speaking of EGT calibration. If the EGT reads ambient air temps accurately, does that mean that it is accurate throughout its range??? If not, how do you check the temp when it is reading 15-1600 degrees??

Also, I forgot to mention- in looking at the calibration for my EGTs I have the same settings for both- Scale factor is 1.943 and the low end offset is 38. Is this the correct factory setting?
