I am running the wideband setup right now for the PNP MS3 ECU. I picked up a DLG-1 dual wideband kit with the 4.9 Bosch sensors. I feel like it is common sense but getting some conflicting information. Do you tap into both 02 sensor wires or does this ECU want only 1? It seems like one of those things were you might as well have 2 wideband signals but only tune off of 1. Close to finishing this thing once and for all and I want to take full advantage of this computer.
