    Yep. In fact many people would argue SD is actually better from a performance point of view, but for overall I think Mass Air is more user friendly.

          Two things which I should add to that cheat sheet, for MAF power, you'll want to splice into pins 37 or 57, for ground you'll splice into 40 or 60

            I gave the MAF it's very own ground and bolted it to the fender. Ground is ground.

              Ground is decidedly NOT ground when it comes to sensors and computers. If there is any potential difference (voltage, yes, on a ground) between what the ECM ground and the sensor ground, the ecm will get an erroneous reading as the reference point for the two devices is different.

                indeed. Thats why there is a ground to the back of the engine. its not a ground so much as the reference voltage point. A few tenths of a volt is enough to change things appreciably.

                  Yep and yep. Using the same ground the computer uses rules out any problems.

                    Yup, that's why there is a pin for it on the ECM!

                      MAF uses a key on hot and a ground for the heater element for the sensor. The two signal wires are hooked up to the respective pins on the ECM harness. I didn't think the heater would be as touchy as a BAP which does get it's ground and such through the ECM harness...

                        I believe the signal return also references to ground somehow though, doesn't it ? Or is that strictly from the 5v ref voltage ? Most of the sensors use all three. I haven't done enough research on the inner workings of a MAF to know for sure.

                          ^This would make sense grounding the MAF back into the ECM vs the chassis. Right now I have it grounded to the fender and I get this reading at idle.



                          Im going to ground it on pin 60 and see if there is any difference.

                            Sure enough I get better readings that are much more correct.

                              I didn't see it so I'll ask, what makes the C3W less desirable?
