Wideband Placement

[Absit]

Just curios, where do you put your wideband sensor if you're running an external wastegate and electric exhaust cutout?

You should considering fully filling out your profile

Are you still using your narrow band sensor? Did you hook up the black, orange, white, and red wires to the correct sources?

Just hooking up those wires will get the gauge to work properly. I believe you only hook one set of wires up for logging. It'll either be the 0v-1v(green) or 0v-5v(brown) wire.
In your case you would want the brown wire connected to an un used 5v input that is acceptable to be logged.

Reconnect the hacked wires that you spliced into and connect to a fresh input

If you are not using your narrow band sensor anymore and are utilizing some sort of narrow band simulation then double check your wiring with the above link.

This is my best guess as to what the situation is and a possible solution. Without seeing your connections and where and what you soldered to, it's still an unknown.

WOAH!!!

That is bad, bad, bad, placement then there buddy. That's essentially a massive exhaust leak that the wideband sensor would be seeing then if it's after the cut out; 12ft<36ft.

Closer the better for the sensor if you want very accurate readings.

Sorry for the confusion. I meant to say that its ok to have the wideband 36" from the turbo even if the cutout is 2' AFTER the wideband. It would not work before it at all of course. I did not mean it that way

No worries mate, it happens.

there a crude little drawing.. where the control box is feeding the narrow band signal to the wire that takes the signal back to the ecu,

evo scan is seeing the ecu reading the same as the wideband is reading so at least i know a signal is getting from the wideband back to the ecu

Liquid!! come back i need your expertise
