    Per Cylinder lambda logging

    How can on log individual cylinder lambda?

    I believe #2 and #3 go lean and would like to (possibly) be able to log and manage appropriately.

    Hi Sobiz
    I have actualy done this on our dyno
    We made a special plate to sandwhich between the exhaust manifold and the head, the plate sampled off a bit of exhaust gas from easch ex runner.
    We then piped that to 4 seperate lambda sensors run by 4 of our PLM's
    Results were
    All cylinders within 5% or better from memory whilst under load. (above 100kpa)
    At idle and cruise cylinders 2 and 3 leaner than the rest.
    I will try and find the log file of the results.
    This was with stock set up thou.

    Cheers

    Pics

    Hi I founds some pics of the plate etc
    We piped from the plate to an exhaust manifold where we already had 1 lambda per pipe welded in.
    It was a bit ugly but worked fine on the dyno.

    If you wanted to do this you could actually make just 1 sample pipe up and measure each cylinder 1 at a time. 4 runs and you would have your info.

    Cheers

    Thanks one at a time was exactly what I was thinking. 4 PLMs is a bit much for just me.

    Do you know how thinck that was and what size fittings?

    Need to see if I can find someone to make a plate or I might be able to pull this off myself with some aluminum.

    Hi
    You seriously dont want to pay for one of those to be made.

    If you pay the freight both ways and get it back smartly you can use this one.
    Only other condition is I want to see the data.

    Hows that?

    Cheers

    Thanks, I'll keep that in mind once the motor is back together.
