    Innovate

    Hi all,
    Anyone get the E8 error code come upon there gauge ?
    And if so what did you do I see that you can get a extension for the sensor so it doesn’t over heat but doesn’t seam to last.
    I think I get a new sensor to try it and if that goes I can send it back and get another.
    Any advice welcomed

    Just to add to this when i re started the car it did't want to idle, could this be a air leak ?
    I have cleaned the stepper motor before and it was fine.
    I also have just changed the temp sensor thinking this was a problem but it could be just the 02 sensor give variable readings.
    I did notice that the BOV didn't seam to be working but after giving it a good rev it sounds like it is ok now, going to check all pipe work for air leaks
    have got a bung to try out,but i think the weather will be too wet this weekend so maybe during the week.

    Also i get the engine knock light when i try and give it WOT, it is better after i changed temp sensor but still there.

    Any thoughts on this ???

    I'm getting an E8 error now on mine. I suspect that mine is a faulty sensor as its not well fitted in the exhaust. Car hasn't been used for a while.

    You could try a recalibration.

    The calibration procedure requires that the oxygen sensor be in free air, this
    means removed from the exhaust system completely.
    1. With the sensor disconnected, apply power to the MTX-L.
    When power is applied, all three digits will light up and the needle bar will
    sweep once through all LEDs. Then the status light will turn red and the
    numeric display will read “E2”. This is an error code, indicating that no
    sensor is detected. Leave unit powered on for minimum 30 seconds.
    2. Power down the MTX-L and attach the oxygen sensor using the
    cable provided. When making these connections, make sure they
    are fully seated and locked. Again, make sure that the sensor is in
    free air (not in the exhaust).
    3. Power up the MTX-L.
    Again, the display should ‘sweep’, but instead of an error, the display will
    display “Htr”. This indicates that the sensor is being heated up to
    operating temperature. After 30-60 seconds, the display will switch from
    “Htr” to “CAL”, indicating that the sensor is being calibrated. A few
    seconds later, your MTX-L will begin displaying AFR. Since the sensor is
    in free air, the gauge will default to the upper limit of 22.4.
    The calibration procedure has completed and the system is now ready
    for use.
    Important: You can disconnect and reconnect the sensor and sensor
    cable for installation without losing your calibration. However, if you
    power up the MTX-L without a sensor connected, your calibration will
    be reset (see step #1 above).

    You can leave the sensor in the exhaust. When you do the calibration.
    But you have to ensure the car has been left at least over night with out being started. Even if you turn it over and it does not fire you will have to leave it another night.
    You must ensure any trace of exhaust gases has dissipated and have free air around the sensor in the exhaust.
    This is how I always calibrated my mtx-l.

    I know the innovate manual says remove the sensor from the exhaust but you don't have to.
    You should recalibrate the innovate wideband at least every 6 months.

    These sensors don't seem to last very long. I'm using the newer LSU 4.9 sensor on my MTX-L and got the dreaded E8 code after about 14 months and around 3000 miles of driving.

    Hoping the replacement lasts a bit longer although I'm sure I've read it's the controller (gauge) that causes the failures

    I've had the E8 error a couple of times, always goes away after cooling down though. I guessed it was a dodgy sensor, but I've not got round to changing it yet

    Thanks Dave, I have done it like this but will try and take it out to see if it makes a difference.

    Darren when yours went wrong did it give you incorrect readings or ones that showed you that you was running lean ?

    So it is still giving you the correct readings ?

    Not that I saw. It just decided it had enough one day and constantly showed the E8 code

    So this afternoon I took out sensor and gave it a clean and then calibrated it free air, I also tested for air leaks in the pipes and all was good as far as I can see.
    I then started car and at first it was showing 19/20 for a bit and I nearly turned off but as I went to do it, it started to show 14.6 to 15.1 which is what it would show normally.
    Am I right in saying that if I log with Evoscan the AFR will it just show me the same as the innovate gauge? If yes how can I check to see if the AFR readings I am getting are correct ?

    There isn't an easy way to check your gauge is accurate other than with another one. A friendly garage may be prepared to put it on there exhaust gas analyser for you.
    Evoscan will only read the output from the wideband or from the narrowband but that isn't going to tell you anything other than your gauge is now.

    You could try and log the factory narrow band O2, and the innovate narrow band output. And see if they match.

    Oh and if you don't want to use a laptop to calibrate the sensor.
    1. Disconnect sensor from gauge.
    2. Ignition to acc, not start. Error displayed. Ignition to off.
    3. Connect sensor, ignition to acc not start. Gauge goes into CAL automatically. Once complete, ingition off.
    4. Start car normally with calibrated gauge.

    If you do this first thing in morning no need to take sensor out of exhaust.

    Thanks Dave, I have done it both ways now and I think the sensor is the problem but want to check it before I get a new one. Just incase it’s the gauge that is wrong
