    Default Brand name monitoring vs old school?

    Hi everybody

    Is it really necessary/advisable to use a brand name eg. Madman monitoring system for oil pressure etc etc etc? Spoke to mechanic that said he could put in a normal “meganiese meter” for eg. the oil pressure gauge. Just like the round ones defenders has. No nonsense apparently. A friend of mine’s Madman did just pack up out of the blue.

    I feel these monitoring systems are just so stupid expensive. I just want something that works. Doesn’t have to look 21st century. Just neat and do the job required. Any advice?

    Thanks

    Old school is nice but the Madman monitors 7 parameters, in the same spot one old school one does.

    To have what the Madman does your vehicle will look like a space shuttle.

    I'm happy with mine.

    Please stay away from mechanical oil pressure gauges. I know of too many cases where the supply line failed and spill oil all over in one case the owner lost an engine.

    Madman is a good option and will warn in time. Just take note that on many of out modern marvels you just duplicate readings and inputs to the Madman that are already taken care of by the ECU. Thing is not all the ECU inputs are on display but are surely monitored and will act on deviations outside its set parameters. You can read many ECU inputs with various forms of displays.
    Maybe worth to investigate first before you spend thousands on a duplicate system.

    I do have some background experience in engine monitoring. You can do what you like you can stop an engine on low fluid levels, over temp and many more. Yes these systems save millions of rands but yet hundreds of engine failures still happen even if monitored. Cranks, cams, conrods and stuff still fails.

    In some cases it is wise to monitor EGT on certain engines. I also found that EGT is more a concern on the older type diesel turbo engines with indirect injection and pre combustion chambers. Many cases EGT becomes a problem due to owners fiddling with fueling to enhance power. EGT is also the direct consequence of Air Fuel Ratios that is out of spec.
    It is not what you buy its what you build.

    Thank you everybody.

    I have an old disco 1 tdi. Which EGT monitoring system would you then recommend? Maybe one that doesn’t cost a kidney?

    Find a Little Black Box. https://www.littleblackbox.co.za/

    But I'm not sure why you think around R4k is a kidney and can save your engine.

    Thanks.
    looked at some prices and ends up over R7000 installed. I think it is great saving your engine and all those costs but a bit much in general. Finances are tight in SA as you know. Just want to see if there is someone more knowledgable out there with something thats good but a bit cheaper.

    Thank you all for the advice

    Madman sells an "EGT only" monitor as well, cheaper than the complete monitoring system.
    And then, if you do monitor EGT, how are you going to use those values you see? What are you going to do when the values are not what you want it to be?
    It's like having a firstaid kit but not knowing how to use it, just saying.

    OK, on a budget:

    Buy a Mud pod :




    Now you can run an oil pressure gauge and an EGT gauge and whatever else.

    Fits where your ashtray is on the Defender dash.

    Don't have to hack your main speedo dash.

    personally I'd fit one of these and go mental:

    Some real smart ODB2 displays available.

    EGT = Madman or Avionics

    The only way you can use OBD in conjunction with D1 TDi is as follows:

    "The Discovery 1 300TDi has no OBD capability whatsoever".

    The Madman's water level alarm saved my engine. Water pipe chaffed through.

    So I already made up the money I spent.
    I also struggled to afford it but bit the bullet on my bonus month.

    That is really old school.

    I actually did not refer to the 300TDI but in vehicle engine monitoring in general.

    My take is that the 300TDI is still a pre chamber indirect injected TD engine. So you will need EGT monitoring

    Do you mean I would have to see oil pressure readings etc etc etc when the EGT reading is not what it should be?

    oil pressure and EGT have no bearing on each other

    I think let's start from scratch: WHAT do you want to monitor and WHY?

    Devils Advocate. I need a Madman because I skimp on maintenance.

    Just joking We were in a Madman discussion the other day. Lots of interesting stuff popped up. Few questions could not be answered.

    Like it will save my engine when a water pipe burst. Why does a water pipe burst? Were it over its duty cycle or did the system get pressurized by a leaking or blown gasket? Are we not suppose to replace all rad pipes at 100k km?

    Krap net gat hier op `n Vrydag more.



    Monitor EGT if needed.

    No.
    What is the range of EGT values deemed 'normal' for your vehicle?
    What is seen as a 'high' value?
    How long can you keep it at the 'high' level?
    What do you do if you are on holiday and you constantly see the 'high' value?
    What do you do when the 'normal' range changes?
    etc.

    It is one thing to measure, it is something else to decide what to do with those values.
