Hey guys, just got a quick question. I soon will be getting a Quarterhorse chip for my A9P. I have an AEM wideband air/fuel gauge installed already. I heard that its good to use the wideband gauge to help with the tune, by connecting it to the EGR circuit. I don't have the chip yet, but i was thinking of getting ready. So to use the gauge in data logging, i need to run a wire from the gauge to the computer right? Is only 1 wire needed? 2? 3? I was planning on running the wire so i am ready. Is this all correct? I wont hook the wire(s) up yet, i just wanna get it ran if i even need to do it. Or if there is a better way of using my wideband for the data logging, please let me know. Thanks guys.
