    Default What wideband O2 controller ( Lambda sensor )

    Some research has revealed that the following is available in SA :
    1. Innovate MTX-L : R2850
    2. Stack ST3402 : R4200 ( one in stock at local supplier )
    3. Zeitronoics : R? ( Speedshop . Durban )

    Can be imported :
    1. 14point7 Spartan $125+ $50guage + shipping $75

    Second hand unit in Cape Town :
    Wideband Commander : R2500

    Some internet trolling is putting me off Innovate due to reliability issues. Stephen van Tonder advises against it and recommends the Stack .
    Not really keen to import at this stage - $/R exchange and import duty issues .
    Not keen on second hand as sensor has finite life .

    I would prefer a unit with narrowband output like the Innovate as I can then replace the narrowband sensor curretly installed . If it does not have narrowband output then I will have to fit a second bung in pipe .

    What say you ?

    The innovate stuff has a reputation for short sensor life. No idea how true it is. Other than that it is considered fast and accurate. $75? I think I paid $15 shipping, but that was ordinary post.

    This should really be in the tech section where it might get noticed. Mods?

    I presume you need to replace your standard unit , will Bosch not be able to help ?

    Spitronics sell the Innovate MTX-L at R2850 + R250 courier .

    The standard unit is narrowband - you can not just replace the narrowband sensor with wideband sensor .

    I am leaning towards Stack as I read too many reports on the net of sensor failure on the Innovate . Someone suggested Motec PLM but their unit cost R16000 .

    I kinda like the display that comes with the 14point7 SLC .


    That kit I can land at R3400 from http://www.oxygensensor.net/14point7.php
    Then add the import duty and 14% vat and it comes to R4500 .

    Then I might as well save myself the hassle of importing and get the Stack.

    Does anyone know where these units can be sourced locally at a good price ?
    Autostyle used to have the EVO Wideband gauge on sale a week ago...

    My other option is to import one

    I am not fully clued up on this but my understanding is that you would use this to measure and set the fuel/air mixture - is this correct?

    How and where do you fit it? Is it a permanent fitting or do you test and then remove?

    Yes in my case tuning the carb. A bung is welded on the exhaust just after the branches and the probe is screwed in. Pretty much all modern cars have them to tune their own fueling on a closed loop condition

    I'm pretty certain the M52 2.8i has an o2 sensor

    Yip, the ECU can accommodate a sensor but it isn't fitted in the Defender, only in the BMW platkar

    Awesome, thank you for sharing. Does anybody know who can fit this to a 2.8i Defender?

    Do you want to incorporate the o2 sensor with the fueling system or just keep an eye on things?

    I am not sure. I know there is a post by Abrie where he uses a gas analyzer for testing and a Faultmate for adjusting. If it is possible and cheaper to do this by installing the Lambda sensor and feeding it into the ECU for automated adjusting it would be great. Just not sure if it is possible?

    This is not for tuning purposes, I just want to ensure that the fuel/air mixture remains optimal
