I?m trying to tune a 98 SS. I?m using a AEM wideband. I used the serial input I have the white wire on pin 1 and the same ground is being used for the wideband as the interface on pin 5. Everytime I start the scanner the wideband disappears from the display. If I insert the analog input 1 it?ll display afr accurately but nothing works in the graph and the graph is Set up for lambda. Anybody have any idea what I could have done wrong ?
