**NOTE:** As of 3/15/2010, our cables have been modified to work with these GM MAF "copies". But we still don't like them given their different behavior and lack of proper honeycombs. | **NOTE:** As of 3/15/2010, our cables have been modified to work with these GM MAF "copies".

The sensor on the left was pulled from an actual GM car. The sensor on the right appears to be a manufactured copy of some sort. | The sensor on the left was pulled from an actual GM car. The sensor on the right appears to be a manufactured copy of some sort. | ||

This gets a little more complicated, but the core problem has to do with some electrical characteristics that are different between these two sensors. Refer to the images below (again, **click image to enlarge**). | This gets a little more complicated, but the core problem has to do with some electrical characteristics that are different between these two sensors.

As you can see, the two signals are similar, but different enough to cause compatibility problems. We do not know how well these aftermarket sensors work with a real GM ECU. We suspect that they probably work fine, but they definitely do not work with our cables. | As you can see, the two signals are similar, but different enough to cause compatibility problems.
