Hello Ivan,
It was actually quite straight forward to change the dials and frames on the
German CFS Boost and RPM gauges you had programmed, so that they would
match the default FSFSConv gause set.
On another forum I found an old post of yours with a table of boost pressures
in ATA, inches of Hg, lbs/sq.in, and mm of HG, and this saved a lot of work!
Then it was a matter of just placing numbers conveniently along the scale to
change ATA into inches of mercury.
Good luck with the fridge!
