Hi guys, I recently got around to installing my link g4+ plug in to my jzx100 cresta. I got a tune file from a friend in japan set up for the same size injectors etc to use as a base map. Ive noticed it does not seem to be using the factory o2 sensor is this normal for the g4+ plug in ? i have a wideband input from my AEM but in currently waiting for the expansion harness to be delivered. Is there a way to use the factory O2 sensor in this application ? Thanks
