PIP signal & tach output

I finally got my dual plug EDIS-4 setup working on my airplane. However I need to know how many PIP signals are sent per 360 degrees of crank rotation. Is it two?

The dimension between the two bolt holes is slightly wider for one sensor. And the sensor is a bit fatter. http://www.e-webcatalog.com/wells/PartForm.aspx?Part_no=SU4101;F3DE-6C315-AB/F3DE-6C315-AB&Manuf_No=PA Wells: Manufacturer No: F3DE-6C315-AB Part Number: SU4101 That is the fatter version. ...

VR sensor dimensions

I want to make some custom CNC brackets to hold the sensors, but both of the ones I bought online are different sizes. The spacing of the two mounting holes is a little bit different. FDEE-6C315-A2B F3DE-6C315-AB Those are the two model #s of the sensors. Do anyone know which model is more popular? ...

I don't want to buy my engine from them but build my own. It's $2500 cheaper that way.

One ignition on the Aerovee is magneto and one is electronic. Both are timed at 28* and the engine starts just fine. (8:1 CR)

Yes, redundant systems is a priority for me.

So, has anyone bench tested their EDIS setup and found the current draw at various RPMs?

I believe the manufacture uses a simple Harley alternator, which is a fixed stator and a rotating drum-like thing with magnets inside. It's 20 amps total power, but I need the ignition to be around 8 amps max so I can run a radio, gagues, etc... I wanted to run dual EDIS-4 modules, dual sensors, and...

But what is max rpm? I've seen some people bench test an EDIS and only see 1 amp at 3000 rpm. Or I've seen figures such as 1 amp per 1000 rpm.

Has anyone bench tested their EDIS setup and found the current draw?

So if the sensor is 90* BTDC and the gap in the wheel is at TDC, would I move the sensor to be at 108* BTDC to get 28* static timing in limp mode?

Use EDIS without MJLJ - Fixed timing for aircraft 28*

Can I use the EDIS-4 setup without the MJLJ (aircooled vw engine for an experimental airplane) and run the timing at 28* fixed? I would like to install the coil pack, trigger wheel, sensor and module but not the MJLJ box. Similar VW conversion aircraft engines run fixed timing of 28* all the time. I...
