Hi everybody, i have a couple of newbie questions.
I'm trying to set my AEM wideband to be as portable as possible.
I was reading through the AEM manual that the UEGO comes with 4 cables, red for power, black for ground, white for analog output and blue for a serial connection.
I connected the power and ground cables to a cigarrete lighter adapter, and i'm now getting power through the gauge. first question is, when i plugged the gauge to the cig lighter this afternoon, i was getting 14.7 readings, i don't expect this value to change since my wideband is not connected. but tonight when i was trying to hook the analog output to the VCM EIO i was getting 14.8 readings on the gauage. is this normal? or should it always see14.7 when the gauge is connected to power with no wideband hooked up ?
2nd question, i connected the white cable (analog output) from the AEM gauge to the VCM EIO, ran the VCM scanner expecting to see the the reading from the gauge in the Vcm scanner, but nothing happened. i'm seen the parameter, but i don't see any value for it.
now, is this the expected behavior since i don't have the wideband connected to AEM gauge, or should i see the 14.8 value displayed in the gauge as a reading in the Vcm scanner ?
Thanks
