## Description

4.9 sensor only for Innovate Motorsports LM-2, LC-2, MTX-L, SCG-1, DLG-1, PSB-1, PSN-1 that are programmed for 4.9. Verify before purchase. The latest generation widebands are compatible with both the Bosch LSU 4.2 and 4.9. Please note that the sensor connector is different for each sensor. Another way to verify which sensor is being used is to connect the unit to the LM Programmer software.

Review: works as replacement for aem x series wideband - the sensor for one of my aem x series widebands went bad & would peg lean at all times. the innovate sensor was the fastest available one so i took a chance figuring it would work and it works just as well as the original aem sensor. the cable on the innovate may be a little longer than the aem one so thats a plus for anyone looking at this as a replacement too
Review: Perfect for ECB-1 replacement - My O2 sensor was shot from my original Innovate ECB-1 gauge. AFR was displaying improperly. This is exact replacement.
