Not to change the thread subject completely BUT. . I have a DD TTPM True Torque Power Module (aka EZ) The directions state that the box is set to three (max) when shipped. WRONG! At least for mine. I was surprised after putting my DDII's in yesterday, I checked the DDTT and it was set on two. Let's see how many people understand the directions. Here is what mine say and how I interpret. FIRST, they show the directions with the box UPSIDE DOWN, with the PCB (printed circuit board) to the bottom of the EZ case and the sticker down. Setting 1, timing only, is TWO jumpers up & down, to the left set of pins, leaving an upper and lower pin open to the right. Setting 2, Decreased low boost fueling (how mine was when I got it) is the two jumpers on the outside set of pins. Finally, Setting 3, Most responsive (DD states for trucks without injectors OR if smoke is not a concern) is accomplished with BOTH jumpers to the RIGHT set of pins, leaving the left set open. Again, with the box in what I call the upside down position. If you read or misread the directions, Setting 2 is the same either way you turn the box BUT 1 & 3 are reversed if you look at the box wrong. Last thing, I have mine on 3 now?, DDII's and NO SMOKE. Is it because of my AFE filter & straight through exhaust? PLEASE correct me if I am wrong and advise on the smoke issue, anyone??
