OK – they have two:
10-180ohms and 240-33ohms. Which? I’m assuming that the 240-33 ohm is 0
psi at 240 ohms and 100 psi at 33. Can I calibrate the EM-2 to understand
backwards increments (i.e zero offset 240 and increments of whatever 1024-207
is times -1)?
Oh BTW – how does the
EM-2 get RPM? The Tach Sense input is for “Lycoming Only – from Mag
Lead”. Is it getting RPM from the EFI primary injector duty cycle?
Tracy?
Tracy recommends VDO
0-100 psi for fuel and oil. I had a 0-80 VDO on hand, and was able to
calibrate that to the EM-2; no problem.
