 **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"​. ​ But we still don't like them given their different behavior and lack of proper honeycombs.

 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. ​ Refer to the images below (again, **click image to enlarge**).
