    Innovate LC1 wot issue

    I have an issue with my Innovate LC1 wideband at WOT.

    Cruise conditions show a consistent 14.7-15.2. Once I WOT it, AFR's either stay exactly the same, or LEAN out to around 16-17. As soon as I let off the throttle, the AFR's dip down to around 10 and immediately return to ~14.7 at cruise.

    Both exhaust gaskets to the DP are brand new. I have no knock on the logger, and the car pulls strong with no timing retard. Obviously, 16-17AFR at WOT would blow my engine, so it's just not right. The unit is accurate for closed loop operation. Why is it doing this at WOT only?

    Vacuum reduction, Powdercoated misc, cruise relocate, Evo9 BOV, Custom catch cans, Russell fuel filter, SS braided fuel lines, High flow fuel loop, Autogage fuel gauge, Catless DP, DNP Y-pipe, Fuel pump hotwire.

    Have you tried to calibrate it again? Those LC1's will randomly loose calibration occasionally for whatever reason. How old is the sensor? Typically the sensor will throw an error on the unit if it's bad but I suppose it doesn't have to.

    Bad sensor. My first one went full lean as soon as I went WOT. The best thing to do with these sensors is to not allow cold air to pass by an already heated sensor, ie turning the key on without starting the car and the O2 heater heats up the sensor; then you start the car and a rush of cold air goes by it. My first one lasted about 2-3 months. The one that's in there now has been flawless for over 2 years. If you need to just run the key to on without starting it, turn the key off and allow some time for the sensor to cool off before starting the car. The manual states something to this effect on page 8(not exact words but, this is what I was doing before my first one went bad and I stopped after I bought a new sensor and it has been flawless ever since). Innovate gives a 6 month warranty as well, if you're still in the warranty window you may want to try that.

    Yea Terry, It's in calibration. It pretty much has to be since cruise conditions are right where they should be.

    Makes sense. I've sat in the car before with the key on for a long time before starting the car. I'm still in the warranty window for sure.

    I've seen calibrations fix what you're describing. Sometimes the AF will be correct and other times it will be off. Doesn't make sense to me but it's worked on mine.
