    Easy enough to install, and I like that this Wideband gives almost instant AFR response numbers

    The AEM works and the installation was straight forward. Be warned this model does not have a narrowband output like previous models. Not really a problem as most will be using standalone engine management.

    This was very easy to install and seems to be working well. I am using this with in a naturally aspirated 1990 miata with a Megasquirt ECU. I had some issues at first because the signal ground was not connected very well, so the numbers were sporadic.

    To install, I used an Add-a-fuse in the footwell fuse box in a switched 5V location with a red 5 amp fuse. The ground wire was run through the firewall by the pedals. The White wire on the AFR guage (signal +) is run to pin 21 on the Megasquirt Options plug. The Brown wire (signal -) is run to pin 22, which is specifically the signal ground pin. One option is to run the red wire to the switched 5V option pin on the Megasquirt as opposed to the add-a-fuse I did.

    Make sure to calibrate the O2 sensor BEFORE putting it in the exhaust. It must be clean open air when calibrated. Hope this helps anyone! Also, thank you to FM for calling me to ask if I needed any assistance. That was a very nice gesture and was very much appreciated.
