sounds like the Innovate MTX Wideband sensor isn't too reliable. Anyone seen this ebay listing for the MTX sensor priced at $156 yet?
Innovate MTX L Digital Wideband Air Fuel Gauge Kit Wide Band Wideband O2 Sensor | eBay
Looks like a good deal but the feedback from this thread seems to indicate otherwise.

I had a much easier time with my MTX-L install than a lot of people indicated from their LC-1 experience. To be expected, but there you go.

Yeah the LC2 looks like they fixed most of the issues with the LC1. Now you can actually locate the controller inside the car, the wiring looks less shitty. Still only has one ground and questional electronics in the controller. But the electrical problems in the controller were pretty much 100% related to the damn thing getting roasted in the engine compartment.

I have my LC1 route through the shifter boot and the controller sits next to it under the center console. It keeps it out of the heat but damn is it a tight fit. the LC2 was easy to hide the controller behind the radio and we ran the wire to the sensor through the firewall. **** was CAKE

I had my LC1 in the same exact place next to the shifter. I had troubles with the unit loosing calibration and eventually killing sensors so I got rid of it. Switched to a Zietronix and that has been good. Also the signal to the MS was less noisy than the LC1 so easier to tune with.

That wasnt noise from the LC1 it was because you had it setup for instantaneous update rather than 1/12th second averages. Instantaneous is too fast, is the default setting for the LC1 0-5v output, and is completely a marketing thing so they can claim to have the fastest wideband.

Never knew about those settings. Oh well. It wouldn't have fixed the issues with the sensor calibration. For reference here is a pic of the afrs it would report with the car idling. It wasn't just a loose connection since it would slowly over time display leaner and leaner until this. Free air calibrations worked at first but then would stop. Replacing the sensor would fix it temporarily but after time it would happen again.

Back on the topic of less expensive wideband setups- has anyone tried the 14point7 lambda controller (this is the version with removable plug)?
Spartan Lambda Controller | 14Point7
$75 for controller + $50 for a sensor off of amazon.

75+50=125 and no gauge and your venturing into unfamiliar ground. Or you could get the LC-2 with out gauge for 189 and you know it will work or the MTX-L for 199 which will also work well.
