What is the purpose of the calibration resistor?
The resistor fine tunes the injection pump much like the adjusting screw did on older non-electronic pumps. The resistors are available in values 1-9. Stock being a #5. Diesel enthusiasts have known since 1994 that the #9 increases fuel rate by 6% over the stock #5 and everyone knows that with diesels, more fuel equals more hp. The beauty of the #9 is that due to increased operating efficiencies, it will also usually produce better mileage too, if driven sensibly. Q: My truck is experiencing stalling and once in a while it won’t start at all. I suspect the PMD is bad. Will your FSD Heat-SyncTM solve my problem? A: As long as you install it with a fresh PMD, as in our “kit” version, yes it will. A cooler alone will not fix an already toasted PMD, just prevent it from happening again. You will need a new PMD. Q: How can I be certain my stalling problem is the PMD and not the injection pump? A: The PMD itself does not have a failure (DTC) code of its own. If no “check engine” light is com
