Which Stand Alone AFR gauge?

    After killing a turbo , head, manifold and a good few other things on my first engine im a touch paranoid about fueling,
    I know the ECU has all the toys in place to keep an eye on this but... the car show'd no signs of problems before it died before... so obviously mapping/ faulty components can trick it.
    So... as alot of people i know run stand alone AFR gauges i thought i would get one... I went for the innovate MTX range as it was simple and compact to fit , I know people with this same gauge and have no problems but... They have lancia's, Astra's and Honda track cars.
    My problem is the probe over heats ( i think this is the problem) and the gauge goes into fault code mode if i drive steady . I think it doesnt like that the Injectors turn off on over run because if i drive "a little enthusiasticly" there isnt a problem.
    Is there a kit out there that has no problems with the above?
    I concidered a liquid S3 gauge but that uses the probe and reading the ECU uses, i like the idea of a second opinion.
    Any ideas peeps?

    The probe is quite far away to be fair,
    Its at the front of the decat section,
    Is this the problem?
    It worked fine in a simular position on my mk2 golf ... all be it with a completely diffrent engine set up

    I have the said innovate mtx and an LC1 kit sat at home... but if they arent going to give a good reliable reading... need to swap them/ sell them

    Look in Prawns thread, he has an AEM which is very nice.

    You distribute AEM don't you Bill?

    I've recently installed an AEM Uego Wideband gauge in mine Paul, and I'm realy liking it.

    No problems on a cruise down to cornwall and back, then 90 minutes each way to Bills and back, followed a week later by 2 hours to Nikis each way.

    Not had any issues with the gauge in that time. On overrun it just displays --- then reinsates the reading the instant I touch the throttle.

    Ia lso think it looks better than the innovate alternatives, with the black / red blending in nicely to the audi interior.

    the further away from hot things the more sluggish it will be (defeating the purpose) and its internal heater will be working a lot to maintain its temp for measurement.. It should'nt overheat like yours says is, but its not in a good position either

    I have a 4bar reg and new fuel pump.
    My worry is only if i push on more with breathing related mods i will go beyond whats doable ,

    Bill,
    I know the probe is a little too far down stream to be ideal.
    But it was only easy place at the time. ( no excuse i know)
    But i figured that some tuners put a lambda probe in the tail pipe of a car when tuning/ mapping it. It would be ok for me?
    Bad thinking ?

    AEM instructions state that it must be at least 300mm from the turbo or it'll get too hot. I think thy suggest something like 24'' from the turbo! So bottom of the downpipe probably isn't that bad.

    given this post stems from the mtx faulting because of overheating? I would suggest its just faulty...

    and yet VAG located the same probe a few inches from turbine outlet and they last for literally years

    Well , rather randomly the gauge seems to be working ! Nothings changed or been reset... just a blast through a tank full of V power, Refilled and seems to be ok for the moment.
