I have replaced an RMI with the D10 EMS and all is well except for the following three items. (1) I have individual switches for electronic (Lightspeed) ignition and mag. The feed from the mag to the EMS goes through a DPDT switch on the EI. With both on, or just EI on, EMS reads EI and reads correctly. With the EI off and Mag on the RPM reading is 1/2. (2) I did not change fuel pressure sender and fuel pressure appears to be 1/2 actual. (3) OAT reads constant -45. Any ideas on how to correct these? Thanks.

On RPM, it sounds like the pulses per revoloution setting for one of your RPM inputs (the one from the mag) needs to be halved.
On fuel pressure, we make no assurances that other pressure sensors will work with our systems. We characterize each sensor we sell or support, and a table of those mappings to the sensor type selection under the EMS Sensor Setup menu can be found in the installation guide. You should check and see if one of the other sensor type settings works for you. Else you may need to purchase one of the sensors we sell for best compatibility.

Since both the EI and mag feed through the DPDT switch, only one can feed the EMS at any given time and in my case pin 33. If I send the mag to pin 32and leave the EI on pin 33, which source will the EMS be displaying when both the EI and mag switch are on.

Right - what you want is a mag p-lead coming directly to one of the pins, per the manual, and then the EI coming to the other pin. Then, set the pulses/revolution accordingly. The EMS chooses one of the two (randomly, if they're both alive), and checks the other pin when the active source goes away (during a mag check during runuup, for example).
