Trying to trouble shoot. Created the serial adapter and installed the aem wb. I start logging with evoscan, the external wb reads for about 10sec and then stops at the last afr. I'm assuming its my ground. I'm gonna try the spot under the glovebox the ppl recommend.

Question... my aem wb install. What do u do with the white wire should that recieve any power at all. I have it receiving power from my cigarrette lighter... Is that correct

 

leave the white wire disconnected. that should not be going to anything or anything going to it if you are using a serial cable to log.

im using a ground behind the radio.

what usb/serial adapter are you using?

what version of evoscan are you using?

 

For the white wire
