If you want a 4 wire O2 sensor let me know. I bought it new from Huntley a while ago, but my wrench installed one of his own instead.
I'll give it to you real cheap to make up for my late cancel on the dyno day. I'll even meet you half way to pick it up.
Let me know if you want it. I'll post a photo later on when I get home.</strong><hr></blockquote>
what sensor do you have and how much did it cost?
From what ive heard 4 wires are the only good ones.

Mdanger, that is the best kind for monitoring...but that type cannot be used as a replacement for our O2 sensor in the car.
That looks like a nice system there though...hmmmm
I don't think I have the cash nor the need for it.
The DME is designed to work with a 3 or 4 wire narrow band O2 sensor...not a wide band as the 5 wire is.
If you look at the graphs for the voltage output vs. A/f ratio you'll see why

"have you guys looked at this?

You can use a wideband O2-sensor with our cars with a circuit that mimicks the stock sensor. A flip-flop with a comparator should do. The current LambdaBoy actually has this circuit built-in or as an option.
