I am currently in the market for a complete wideband O2 set up that would include sensor, gauge and anything else I might need for my 1977 Corvette. Does anyone have any suggestions?

The AEM Wego is a good unit for a good price. Its accurate, repeatable and doesn't require free air calibrations. About $180.

I also use Innovate Motorsports LM1s on my car and bike and those work great as well, but are WAY outdated.

Stay away from the Innovate dual channel wide bands, they are JUNK...

For the money, the AEM is tough to beat

I just got a new Daytona Sensors (AKA Daytona TwinTec) Wego III to replace my aging Wego II. Use a TPS or MAP sensor and record throttle position or manifold vacuum/pressure along with RPM and AFR to aid in tuning. It will record 2 hours of data. It can be set to view AFR for different fuels or Lambda, which I prefer. It has a built in USB to plug into your laptop or computer and software on CD.

It has free air calibration, which I prefer because it keeps the O2 sensor more accurate as it ages.

I'll probably buy one from these guys when I redo my exhaust, but I already have an investment in Arduino hardware, shields, sensors, and the software to run them (software is free, it is just the learning curve in that case). They use a Bosch sensor.

This is the unit from Zeitronix I have for my 1978 corvette. You can use a display, but you can also connect to a PC for complete data logging. It also has additional inputs depending on the units you have.

Check out there online manual to see the complete options you have.

Here is what my laptop display looks like. I am measuring. AFR left & right bank of the engine, engine RPM, map sensor voltage & PSI, engine vacuum.
This is a WOT run 1st, 2nd, 3rd gear and marked a few spots to check the AFR at the RPM values,
shows
AFR 12.6-12.8 @ 3892 RPM 1st gear.
AFR 13.0-13.2 @ 4364 RPM 2nd gear.
AFR 13.1-13.3 @ 3945 RPM 3rd gear.

You can move the markers anywhere along the gragh. You can also see the display / graph update in rear time.

This is the best wideband O2 meter for accuracy and consistency, not to mention outputs for logging etc... Its pricey though...

I have the AEM as well. I got it from Summit and it works fine. I use it for tuning my carb o I dont ned all the bells and whisltles. I have it mounted on the A pillarin a heat fit gauge mount that I painted to match the interior. Its not noticed by anyone at the car shows and I can hide it behind my hand by adjusting my grip while driving. When Im looking for WOT readings its right there in my line of sight without looking down at the normal gauge location

Looks like that is an improved version of the original NGK AFX. I have run the old NGK in my Z06 for years now. It works great.

That's exactly what it is.... And they are STILL one of the best....

PLX makes them as well.

I have the Innovate Motorsports LM-1. Lars does too.
