Hello
I would like to replace my VDO tach/Hobbs with a Map-4. The aircraft is a Bantam with a Jabiru 3300 engine. I have a few questions..
Will the Vdo's rpm pickup work, if not what will I need?
Can I use the manifold pressure input to measure fuel pressure, if so what pressure transducer will I need.
That's it for now.

Assuming your engine is normally aspirated manifold pressure is generally negative (a vacuum). Fuel pressure is positive so I vote no on that part.
