WTB: MTX-L gauge/controller or cheap used wideband
 

Like title says, i need just the gauge/controller.

Bought one used a few months back, turned out to be DOA. Would like to try another in the hopes that the sensor is still good and maybe save myself a few bucks since this is a GRM Challenge car.



Alternatively, if someone wants to cut me a deal on a used MTX-L kit or something else that has narrowband simulation that doesn't suck, that'd be cool.
