ok, guys so I have a Aeroforce dual wideband and between HP Tuners and the gauge, they are not reading the same. I have tried to fix the ground offset but for me, it would be a negative offset witch I no is not right. has anyone ever had that happen? and finally not sure if this has anything to do with why I am not getting a good reading with the gauge to hp tuners but the wires going into the black box the connector seams lose to me this is the connector that gives the info to HP tuners from aeroforce.
