I no longer have any need for this so I am taking offers over $50.
It is the jaycar "Smart Mixture Meter" which indicates the Air/Fuel Ratio of your mixtures going into the engine by displaying them on a series of LED's. It dims automatically at night, and also indicated when your engine is running in "closed loop" by cycling the LED's. There is a lean out Alarm which sounds whenever there is lean mixtures and you put your foot down (Something which hopefully you will never hear). If the engine runs lean while its making power it wont last long.
{DESCRIPTION}
The kit in the link is supplied as components, which means you have to assemble the PC board and solder the components yourself, however I have obviously already done this. I avoided the need to use an air flow meter (as the falcons dont have one) by hooking into the TPS and increasing the sensitivity.

I can explain how to hook the unit up (4 connections, power, earth, oxy sensor and TPS sensor), and calibrate it.

The LED indicators are currently arranged on a blank that fits in the stereo console where the ash tray normally is, thats why I said in the title it suits EA-ED. howver you could take the LED's out of the blank and arrange them however you want (you may need to extend the ribbon cable)

Considering the cost of the kit, how long it took to construct, and all the extra effort that went in to fitting it to the blank (ribbon cable is a b**ch to solder) $50 is a steal.I will leave this up for a few days to get the best offer





For those with an Autospeed subscription, search for "smart mixture meter" there should be around 4 articles on it.
