It sounds as if you've done things correctly:
Sensor red wire to SV-EMS-220 37-pin connector Pin 15
Sensor white wire to SV-EMS-220 37-pin connector Pin 6
SETUP > EMS SETUP > SENSOR INPUT MAPPING > C37 P6 > PRESSURE + ROTAX OIL PRESSURE (HONEYWELL) + OIL
We've had reports from other customers of a fair number of problems with these Honeywell oil pressure sensors.
We installed a Honywell Oil Presseure Sensor ( diliv. from ROTAX) withe the Skyview. (Red pin 15 (12V) und white with Pin 6) in the Setup menue we chose the right type "Honywell Rotax)
HELP!! It does nt work!
