I now have my 85/305 tpi so that I can drive it with the laptop plugged in. When I put the plug in to the aldl plug in the car, the idle rpm's increase from about 650 to 1000 rpm. When I drive the car there is noticeable preigniton and then the knock sensor must work as the performance drops right off. Without the interface plugged it the car runs fine and has good power. I am using the 1 transistor interface and have a 870 ecm. Any idea's?
