Fitting an Advanced AF-2500 Engine Monitor to Vans RV7.

The Advanced AF-2500 monitors all the engine parameters - Manifold Pressure, RPM, Oil Pressure Oil Temperature, Fuel Pressure, Fuel flow, fuel tank levels (in flight and on the ground for tail wheel a/c), Amps, Voltage, EGT & CHT on all 4 cylinders (also available for 6)and some other aircarft parameters - Flap position, Trim positions and user configured.

Test Flight with Bob Cole at the controls

This is the Advance Analogue Module.

This is where all the sensors are connected to. I have sited this on the instrument sub panel. Some other builders have sided this module behind the subpanel but I think this makes it difficult to maintain.

This is showing the rubbon cable between the analogue and digital display unit. The 'kit' is supplied with a larger longer cable (that is also much heavier!) I contacted advanced for this shorter cable. They did offer to do an exchange but the cost of shipping made it not worth while so I just purchased the replacement. Looking at it, if you sourced the connectors you could make your own.
THE YELLOW tape around the digital unit is to cover the air vents during construction/building.

The digital display unit (There is a cover over the display).

I had thought about fitting the Analogue unit on top of the map box.

The RPM sensor

The red part is the sensor.

Manifod Pressure Sensor

I have fitted the manifold pressure sensor on the firewall.

CHT Sensors.

The CHT sensors screw into the underside of the cylinder heads.

The CHT .

CHT sensors fitted.

EGT Sensors

The EGT sensors fitted to the exhaust - see manual for distance/position.

Oil Temp Sensor

You need to remove a blank and fit the oil temp sensor near the oil filter. It shoild be wire locked in place.

Building the Baffles with the Vans Baffle Kit

Oil and fuel pressure sensors

The oil and fuel pressure sensors are mounter remotly - via restrictor valves. The Vans manual suggests one part of the remote sensor block is removed but I fould the two outer parts of the block posioned the sensors and remote pipes better.

This is the restrictor valve for the oil pressure remote sensor.

Fuel Pressure Sensor T and restrictor valve

The fuel pressure sensor is T'ed off from the out side of the manual fuel pump. I am sensing the fuel pressure after the manual put as this will show the function of the mechanical pump. It will also show up the electrical fuel pump pressure changes.

Fuel Flow Sensor

The fuel flow sensor is located in the fuse just after the electrical fuel pump. There should not be any bends in the pipe or angles jounts etc within 5 inches (sorry US imperial measurements) of the sensor.

Fuel Flow Sensor (with injection high pressure fuel pump)

The fuel flow sensor should not be in the high point of the sensor.
