For this method, do not set MAP to the local altimeter
(Kollsman window) setting since that setting is the pressure
at sea level, and is not the same as your field elevation
pressure.

Section 9 - Programming use of Factory Original TIT Probe
If your aircraft is using the factory original TIT probe and gauge, you
should calibrate the EDM for that probe. The factory original TIT probe
must be a type K and the leads must be wired red-to-red and yellow-to-
yellow. Both the EDM and factory original gauge may be used
concurrently. Due to the high input impedance of the EDM instrument, it
will not affect the accuracy of the factory installed probe or gauge. In
normal cruise flight, record the difference between the factory installed
TIT gauge and the EDM TIT reading: TIT gauge _____ EDM _____.
If you haven’t already done so, start the pilot programming procedure,
by simultaneously holding the STEP and LF buttons for a few seconds
until you see the word PROGRAM for two seconds.
