Pc driven ego analyser kit

Hey guys and gals

would anyone be interested if i could start making these unit's again, Dicksmith use to sell these unit's in kit form and hook up to a live computer/laptop to see what your exhaust gas mixture was, i remember i had a 7 inch screen built into my dash that constantly displayed the EGO mixture on the screen, i have still the software for this unit as well,looked pretty impressive when it was on with like a heart rate monitor and large display digits for read outs,,when you revved the engine the mixture line would constantly scroll and rise and fall like a heart rate,,unit ran of a 9v battery,but i used a relay and switch on the dash so i could turn the unit on/off.,,,,if you guys/girls are interested i can post of what the display looks like as well

Excuse my ignorance. So this thing measures the AFR's? Or is that different?

It hooks inline with your sensor on your exhaust to measure fuel mixture/air mixture :)

Found this photo of what the screen used to show if the car was running rich or lean :)
