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?
