Only logged in customers who have purchased this product may write a review.

Does it include mounting hardware?

  • Yes. It includes a “cage” to help mount in a flat panel, as well as a small wiring harness.

Will it fit in a gauge cup?

  • The MTX-L will fit in many gauge pods or cups meant for 52 mm gauges.

What fuels is this wideband compatible with?

  • Yes, it will support gasoline, ethanol, methanol, diesel fuel, propane, and CNG. Note that the minimum measurable AFR is 0.5 lambda. If you’re using methanol as a substitute for an intercooler, it may not be able to read mixtures that rich.

What sensor is included?

  • A Bosch LSU 4.9 sensor is included.

How is this different from part number 3845?

  • The only difference is the length of the wideband sensor cable. The 3845 has a 3′ sensor cable; the 3844 has a 8′ cable. Generally speaking, the 3845 is better suited for powersports or other small engine applications and the 3844 is used in full size vehicles.

    Asked by Dakota

    Yes. Just run its analog output to the MSPNP's O2 sensor input and make sure the stock O2 sensor is disconnected.
