Hello. I bought a spartan 2 controller, wideband sensor and gauge setup about a year ago and just got around to installing it. The afr numbers seem normal, but the red warning light is constantly on. Any idea what could be causing that issue? I have the power for the controller wired through a relay that is triggered by the fuel pump power, a 5 amp fuse direct from the battery. The ecu is using the stock narrowband, so i am not using the brown wire. I also do not have the blue wire for the led set up yet. The black is grounded at the same location as the ecu ground, beside the unit to the body under the kick panel, and the white is grounded at the next nearest ground point. The sensor bung is welded into the 3 inch exhaust, about 36”back from the turbo. Any help would be appreciated. Thank you

So you are not referring to the LED that reads sensor temp?

I’m referring to the red light that says “warning” underneath the afr on the face of the gauge.

I have used that gauge for over 2 year with PE/8UA/DIYPNP/and PiMP ECUs and that light has always stayed on. I have used the gauge with both the stock narrowband and the Startan wideband systems. I did not connect the blue Temp wire and LED. I have never figured out why it stays on. The gauge readings are always within 0.2 reading of Tuner Studio,( which I attributed to time delay differences). I finally gave up and just ignore it.

According to 14Point7.com user manual, "White" " Ground" "Leave disconnected to turn off warning LED". I would disconnect the white wire and see if that LED goes away, that what I did on my installation.

I've asked Alan at 14point7 for feedback, I'll let you know what he says.

Sounds like the gauge warning lights are wonky and the best bet is to just not use the white wire. The warning light isn't overly useful if they are warning at above 20 (engine won't run up there anyway) or below 10 (engine won't run there either without massive misfires) so it's not really warning you of anything you won't already know.

Interesting...Thanks for chasing that down for us, Shannon!  |
