Review on Innovate Motorsports 3918 MTX L Plus by Kenneth Harris

Installed according to innovative instructions. Except for using a relay and dedicated power/ground directly to the battery. Installs away from ferrite block ignition components to eliminate the possibility of noise interference. Driven less than two weeks. Sensor failed, horrible e8 code with shaky readings everywhere. Contacted Innovate, replied that I had fouled the sensor with about a dozen of my WOT settings, which dip into the high 9:1 range of 5500-6800 rpm. Total time in this area is less than 100 seconds. I checked the logs. What is the point of broadband that cannot be used like broadband? What the heck would a car owner do with a supercharged engine when the car has to run rich to function properly? The rest of the time, the car is in a closed control loop with narrow-band control and works at a standstill. WOT pulls at the correct 12.5:1 ratio only up to the top end of the RPM range. Nothing bad to say about the seller, just let down by the typical "it's your fault" attitude of innovation with a product installed exactly to its specifications by someone experienced with electrical components. Two weeks and a failed sensor that has never been subjected to shock, thermal or physical stress, installed and working exactly as specified by the manufacturer - that's a bad sensor or controller firmware. Don't rely on a guarantee. I ordered a new sensor from my bag hoping I just had a bad sensor. If that fails, the whole thing gets torn up and sent to eBay.
