new $EE tuning thing!

that's weird for sure. do you have the analog output through the a/c input or what? what are you using as signal ground there?

Thanks for reply Steve. Awesome program you have put together. Looking forward to playing around with it.

My white analog output wire is connected to the Red and Black wire of the AC pressure sensor line.

Not sure what you mean by a signal ground. Should I ground one of the AC pressure sensor wires?

I tried hooking the gauge power lines directly to the battery. No change.

so if you disconnect the signal wire but not the gauge power, then what happens?

Tried it both ways. I get an error if the signal wire is connected or if it is disconnected. The only time I do not get an error is if the power to the gauge is disconnected.

that's bad news for sure. i don't suppose you own or have access to an oscilloscope?

[Casey96SS]

I do not have an oscilloscope. I do belong to a car club I can ask to see anyone has access to one. Would it be a real involved process to figure out the problem if I can get access to an oscilloscope?

it would just be nice to know what kind of interference the wideband's power supply is introducing
