That's what we are gonna go do in the next week or so. I can understand a low reading, high reading is odd. there is always the possibility that the other engine is in fact reading low...
If the probes get swapped, then the replacements probably have to cycle through the engine to prove the point. There had been a split between the indicated and DEEC recorded data of the same amount, then they elected to match, more or less.
