I'm having an issue when my wideband isn't plugged into the HPtuners cable it reads higher than when I plug it in. Example when the car is off and has been for a while it will output 4.96v at the green connector, immediately plugging it into the HPtuners cable it drops to 4.6v at the green connector even though its still putting out 4.96v at the wideband controller. My box also spits out at least .1λ difference from what is picked up in HPtuners, I know adjust the offset but the problem is its putting out the right voltage its HPtuners that is making it drop. Any suggestions other than changing the offset? because its farther off the farther from stoich it is.
