lamda convert reading from volts

[Graham]

I've got a lamda guage in the car, and this has a 0-5v output which i've connected to the data logger.

Ow i can see the 0-5v trace ok but i need to convert this to somthing meaning full either lambda or air/fule ratio

any ideas

Its the lumenition AFR004 kit. It uses a 1v Zirconia type ego supplied by lumenition. the display has the 0-5v output for the logger.

The instructions are really helpfull it just says for data aquisition the afr004 provides a 0-5v replication of the 0-1v signal from the sensor...

Im just using it as a guide really to make sure it doesnt run lean. the display is just the 19 led variety. and i was trying to get somthing reasonably meaningfull out of the logged data...

The motor is just a 4ltr RV8..

incedentaly I had a mooch at yer profile. I helped a mate Build a dakar many moons ago
