Be Glad to, Joe.

Its a fairly easy circuit with one easy = to wire=20 chip and while you can use individual LED diodes, I would recommend one = of the=20 10 LED bars - much easier to wire up in my opinion that 20 tiny wires = from 10=20 LEDs.

I'll need to dig around in my files and = come up=20 with it. Send me a reminder if you don't hear from me in a couple = of=20 days.

Ed,

Would you mind sharing any of the = electrical=20 specs and / or wiring diagrams for you LED A/F indicator?

Thanks,

Joe

I think the one Tracy sells is as = good and=20 inexpensive as they come. All of the ones that I am familiar = with use=20 the same basic design (except for the latest ones that use the new = (and=20 expensive) so-called broad band sensor). I personally like the = ones=20 that use the 3/4 wire sensor (these have their own heating element) = as you=20 do not have to wait for the exhaust gas to warm up the sensor before = it=20 start working. They are a bit more expensive that the 1/2 wire = sensor=20 may $10-20 more.

I built my own LED A/F indicator = and=20 integrated it with my fuel monitoring system. But regardless = of=20 whether you build or buy, they are well worth having, in fact I = would rather=20 lose my EGTs than my LED A/F indicator.

Thanks Ed,
By = any chance can=20 you recommend one A/F indicator?. I have installed the single wire = O2=20 sensor that came with the engine. I may even replace=20 it?
