    Re: AFR Wideband for tuning carb

    Yes and yes.

    I have a carb cheater which is like a wideband with the ability to self tune (within limits).

    I also have a wideband rigged up to a cigarette lighter so it can be swapped from vehicle to vehicle for tuning.

    I have one on my 66.   Allows perfect carb tune

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Re: AFR Wideband for tuning carb

    What exactly would you like to hear that is different from installing an instrument that will provide real time AFR data?  I've had mine in for years now and I always know how the carburetor is doing.  They are an inexpensive way of actually knowing the AFR.  The only reason I would not put one in would be if I were not going to be running a carburetor.  And even then an O2 sensor would need to be installed for the EFI.
    (By the way, mine is an AEM 30-0300 X-Series)

    Edit:  In December of 2017, mine cost $179.  The current price on Amazon for the same one is $189.  Only $10 higher after 7 years.

    I saw some AEM 30-0300 x-series on ebay even cheaper not sure if they are real  may be a knock off.

    I looked on eBay and saw a higher price for new kits with the O2 sensor.  Don't buy used and be sure you get the proper O2 sensor with whatever AFR kit you buy.  Remember it is the O2 sensor that provides the data.  The rest of the kit is the display.

    Re: AFR Wideband for tuning carb

    Billy - If you are interested, I have an un-used “Innovate Motorsports 3918 MTX, AFR Gauge” that is 4 years-old, and was never installed as I went to an EFI setup that has an AFR readout.
    I’m sure we work something out if you’re interested, PM me.

    65 Fastback, 351W, 5-speed, 4 wheel discs, 9" rear,  R&C Front End.
