    That’s all been up hill so far, is it time to come scudding down the other side yet?

  • Earlier VVC cars had a coil pack “block” bolted to the rear of the engine & loooong plug leads to the head, I’ve changed this now to the later & now more conventional plug cap coil.
    This was prompted by an occasional miss fire & I included a picture which tells the remainder of the story.

  • I have an f & thus have one less sensor than the tf. The post cat’ sensor is there to ensure the catalytic converter is up to scratch & that the pre cat is feeding the appropriate information to the wizardry department & that department is adjusting the parameters around the car to ensure that when the information eventually comes back from the post cat sensor, a smile is formed if all is found to be good. The MOT tester gives you 12 months happy motoring, the sun comes out & the roof goes back.
    That’s the theory & I guess that’s general knowledge.
    Stepping closer to the system introduces values to aim for & these are referred to as “Stoick” values. This is the air/fuel ratio.
    The ideal for a petrol engine is 14.7 to 1; one gram of fuel to fourteen point seven grams air.
    The electronics strives to achieve this ratio but the initial information has to be close enough for the rest of the adjustable perimeters to be drawn in. The prime data comes from the Lambda sensor & the jiggery pokery that goes on in there gives a voltage ratio of 1.0 or the lambda value, or 1v max.
    If your running lean expect that voltage to be as low as 0.1, a rich value would be not much less than 1 & so if you arrange a volt meter across the sensor where full scale is 1volt you will be able to see how rich the mixture is. Obviously if you’re on the rich side you’re going to trouble the tester more than on the lean side.
    I did some research into this a while ago & ran a cable from the sensor to a narrow band meter temporarily mounted dash. In addition I arrange a breakout port beneath the trinket box under the arm rest, where I could bring out cables for better test gear, rather than rely on the device donated for these tests.
    This space under the arm rest is the entrance to a parallel universe where various test points visit our dimension for me to play with; you can adjust your hand brake balance in there as well.
    To sum up the pre cat sensor is the device which leads the pack, with everything else falling in behind with the ECU constantly referring back to that sensor.
    For further reading on the Stoich value Google it & you’ll be amazed at all the stuff, however I found one error & that was repeated in most of the writings.
    It wasn’t significant but it goes to show just how much plagiarism the internet creates in so called original bodies of work.
    If you spot any errors in this please rectify, I’ve used most of this information to search out results & the answers corollate with expectations so I can’t be too far adrift.

  • Airportable replied to the topic Tebay in MGF/TF Pitstop
    “Genuine road patina”. Don’t tempt me so, I inadvertently washed a whole load of it down the driveway whilst recklessly using a hose pipe on the car. I never considered how it might be replaced as I watched the last dribbles disappear down the drain.
    Can you supply it in small amounts specific to certain areas?
    One of the best items available from Tebay is their pork & apple pies.
    Whether it’s M6 northbound or south we seem to be inexorably drawn in for pies.
    You can part with a lot of money in their food shop but we’ve never been let down.
    Never

    Are we opening up as a rival organisation to e-bay, if so what are the rates for advertising & does the management get a cut of the profit?

  • Is there not a sound argument for a special Cobber’s guide to Life, The Universe, Motorised things & everything else.
    I would create a computer short cut for that without a moment’s hesitation.

  • That’s interesting their having had problems with their equipment. My chum who does my MOT tests & who had done since the abolition of the man with the red flag, Dave’s kit does a self test against an internal standard & will not allow a test to proceed if there is deviation of more than a few points.
    I’m sure most of us, or at least those who brave the test by close observation will be conscious of time gaps in between tests.
    I believe these periods are part of the self test & resetting to datum in preparation for the next disappointment.

  • My word Cobber, let me be the first to congratulate you on your epic posts. I can’t see there being much you have omitted & I will certainly watch this space for future inspiration.

  • There are untold millions of ECU’s being driven around in every part of the world doing, without question, what they were designed to do.
    From the moment of their first boot until they are decommissioned (in whatever route that might take) these obediently perform with unerring accuracy their tasks & although there are glitches in systems these tend to be external influences; moisture tops the list.
    “Experts” who blame problems on ECU’s are more interested in your money than the health of your car.
    Whatever new witchcraft motor manufacturer institute in their new cars, will be the major contributory factors to your motors ill health until the next brainwave is foisted on to us, irrespective of the true problem.
    Or am I just getting disillusioned with this motoring caper & the folk who profit from it all.
