| The downside, of course, is that if you disable the air temp sensor for speed density operation inside the ECU, then you need to make sure your air temperature reading while doing your calibration drive is fairly reasonable (say between 50-90F). A good working intercooler and some careful attention to your right foot will help immensely with this too. | The downside, of course, is that if you disable the air temp sensor for speed density operation inside the ECU, then you need to make sure your air temperature reading while doing your calibration drive is fairly reasonable (say between 50-90F).

| As long as the GM MAF stayed connected, the offset simply remained constant and you would never really notice much effect. But when you switch to SD, you fully expect to disconnect the GM MAF sensor and that's when the offset makes a difference! Suddenly the pressure sensor output changes relative to what it was when you were dialing the SD setup in using your GM MAF sensor. | As long as the GM MAF stayed connected, the offset simply remained constant and you would never really notice much effect.

| - | To ensure that this isn't a problem, you have to use one of our newer GM MAF cables that provide a separate power wire for the GM MAF's grounding point or you need to [[gmmafcablemod|modify our older GM MAF cable]] (if that's what you have) to add this wire. If you're running a GM MAF Translator device, you could probably do the same ground wire modification as we recommend for our older GM MAF cables, but I can't guarantee that. | + | To ensure that this isn't a problem, you have to use one of our newer GM MAF cables that provide a separate power wire for the GM MAF's grounding point or you need to [[gmmafcablemod|modify our older GM MAF cable]] (if that's what you have) to add this wire. |

| + | If you're running a GM MAF Translator device, you need to do [[gmmafcablemod|a similar modification]] on their GM MAF connector as was detailed for our older cables. This modification involves simply cutting the ground wire on the GM MAF connector and running it to chassis ground instead. | ||
