    My DIGI1 ECU and Wideband don`t seem to get on, 1 option is to refit the stock Lambda probe together with the Wideband probe, problem is I`ve only got 1 hole!

    Is there anywhere that produces a Y type splitter for fitting 2 probes and would this work ok?

    Cheers!

    you can't use a y splitter, the sensor must be mounted directly in the flow of the exhaust gases, a y-splitter wont allow you to do this

    drill a 2nd hole and weld a nut to it?

    ^^ yep thats what id have said,or im sure? [:$] ive heard that the...

    forgot the fekin name [:x]

    the testing tube thing coming from the manifold,i think? you can remove and fit a lambda in there?
    worth a look?

    no you can't do that
    As I said before the lambda sensor has got to be in the direct flow of exhaust gas, yes your best off welding another nut in the downpipe and mount the sensor there

    it would be in the manifold though wouldnt it? where theres obviously exhaust gas.[:$]

    or would it not take the best signal from there?

    not picking,just learning! [:D]

    It`s a 4 branch, it`s all wrapped and I`ve sworn I`d never remove it again :lol:.

    Looking into capping the emulated narrowband signal to 1 volt tops, think it goes to 1.2v at the moment which is too high, causes lean condition in closed loop.

    Bloody cars!
