I've set my car up using a wideband sensor and mega log viewer,but I fancy making a LED AFR meter.
I've done a search but can't find the info I thought I saw on this. site how to make one. Can any one help?
And could one be made to show the actual AFR readings and not just lean ok rich?

I put a link to this site somewhere!! LINKY

Is that the one

Cheers

If you can set the output scaling of your wideband controller to give 0.1v = 1.0 AFR (i.e. 14.7:1 = 1.47v), you can use a cheap LCD or LED voltmeter module e.g. one of these.

I used one of the cheap panel LED voltmeters and took the 5v power source from the JAW regulator, seems to work well but hard to see in sunlight.
