  1. its very complicated but the cook cables are old and not designed to take tiwai capacity, yes power is obviously transported from south to north but it doesn't get all the way to the top,too much loss etc and its not like  you can suddenly double it.

    Im not denying EV are here to stay and going to be huge but even california is turning off and asking people to not charge their vehicles due to overloading

    smart charger , yes they have a timer but you are still asking every car owner to try to recharge from 5 till say 7am and most are 6 hours plus so there is tremendous overlap of times and to say that its cheap because its off peak rates.

    do you really think it will still be off peak when everyone has a EV and is charging overnight it will be max peak and charged as such,

    Rules on RUCs on EVs have been in place for a long time. EVs are subject to RUC, there has been an “exemption” in place for a number of years and was until either a set date or the total number of EVs on the road reached a certain percentage. The end date has been moved out a couple of times but it has now been stated it won’t move again, iirc it’s some time in 2023.

     Cost of electricity + RUC will still be way cheaper per km than petrol or diesel.

    As for the supply grid, a lot rests on the closure of the smelting plant down south freeing up a lot of capacity. With the vast majority of charging done at home the flexibility is there to use “off-peak” periods.

    closing a smelting plant does nothing to power in Auckland, it can't be transferred from one end of country to the other. and flexibility is bollocks, 95% of evs will arrive home after 5pm to go on charge. Unless private companies like wilsons install them all through their multistory carparks

    then you got places like wellington where every govt worker lives with the car parked on the street down a cliff from the house, going to be a lot of extension leads

    the whole thing is a joke

    until they agree to build a nuclear sub sized reactor in a container and place it somewhere near auckland they are screwed.

    aus the country with the largest private solar panel input has now realised it screws the power companies up, they still need to have the generating capacity to cover nights and windless days etc but they also lose all the profits of being sole supplier . their business model doesn't work basically when you have people all giving power back to the grid at unneeded times, but you still need to cover them with generation capacity in case.

  3. and you probably would have found if you waited the battery would have recovered enough to start itself just, spent many frosty mornings turning over cars till just a clunk, wait 15mins and go back and theres enough to fire it if your quick and lucky

    there seems to be enough chemical reaction in a newish battery to kind of float the levels perhaps, not sure of the physics of the thing but it happens. unless you left the lights on and really killed it, no way back from that

    on batteries can't say how totaly impressive these are

    wifes f40 2021 model got a software update that downloaded from her phone to the idrive but never got to a postion to autoinstall.

    google said its always a battery charge thing , you needed to go on a long drive first etc etc so after spending the night on a plain 12v charger there was no difference. about to give up but everyone raves about these ctek so bought one on a good sale.

    24hr later to do the full cycle and bang update went straight through.

    more than impressed, going to do a few other older cars on a restoration cycle now to see what happens but obviously battery tech has moved on from the old cheap chargers of old.

     


  4. all the cheap ones I found on ebay were not NZ compatible frequency wise for our garage

    the trick is to buy the mirror with the buttons, and then dismantle your old garage remote down to its circuit board only , which can then be hidden somewhere inside the roof lining and run a hidden pr of wires from the button on the remote to the button on the mirror. basically you are just using the mirror button to temporarily  short a circuit and its very easy to do. its easy to see the points on the circuit board that the existing switch is actually working on and solder wires to them.

    you can buy really tiny replacement remotes for alot of merlin doors  and you could possibly hide the whole circuit inside the mirror and bypass/cutout their incompatible circuit inside to make room for your hidden

    remote.

  5. I fitted one to an e39 years ago but it went in the headlining as opposed to being part of the mirror, you need to carefully check your frequencies though as garage remotes aren't the same world wide. the wiring was there already and there was no coding involved it was just a straight swop and worked like factory intended with our old 80s model merlin garage

    Should be an option in the doors/access menu that says 'turn off when drivers door is opened' that you need to uncheck.

    no apparently that's only related to the radio or the car going to sleep, lots of confused discussions on that on internet, its designed to stay on until all passengers have left as it detects everyone in the car, so they can listen to radio and have aircon while your filling up for example. that can get confused with child seats etc when you get home to your garage though and actually want it ti turn off.

    3rd world problems I know


  7. Wife has a new toy, a 2020 F40 118i

    couple of annoying issues I can't figure out.

    Firstly the autostop/start is horrible, the car shudders when stopping and even worse when starting, guess that's an issue with 3 cyl as it sounds very tractor like when idling anyway. Goes extremely well when actually running so its not a tuning issue or anything.There is a manual button to disable autostop but it reverts at each journey to back on. I have ordered an enet cable but does anyone know if this is codeable for permanent disable. We don't live in a high traffic area and I would say the auto stop would save basically less than 1ltr of petrol per year.

    2nd we back out the drive, stop and put car into park to shut the gates and the minute you open the door the engine turns off. same on the way home again and you actually have to push the start button to continue. Surely this can be overiden? have never seen any automatic car do this before and its crazy annoying.

  8. i did mine a few months ago, like you was sick of the cobwebs dust and leaves that accumulated all the time. I just lined in jib because of the cost.  skyine garage the studs were 600 so that worked perfect with the sheets hung vertically so the joints were on studs and 2.4 just made the top plate i came up about 12 mm off the floor incase of puddles from a wet car but I also ran a pine skirting around floor because that 12mm gap was just a trap for leaves and crap that blow in and made sweeping so much easier. If it gets accidentally punctured its a 10 min job to replace a sheet. I also ran moulding around the window frames that finished them off because the jibs weak point is its edges. used a couple of pieces of 75 x 18 pine as mounting strips to hang all the gardening crap off at head height

    lined area above workbench in ply for a tool board

    it would have been better in ply or possibly mdf but I did it for $17 a sheet as opposed to $43 I think from memory but money was tight

    has made a world of difference and even unpainted its 300 % lighter in there, should have done it 10 yrs ago

  9. she was obviously driving something pretty damn special though, she could out brake anybody anywhere and just blew past race cars like they wern't even trying, passed people around the outside of a corner, that was some special car in a totally different league, it was a video game style mismatch but made pretty good video for sure.

     


  10. I guess you have to have a point of difference tho

    Sounds good, but must be a huge amount of resource to develop and implement across a range of vehicles every few years...  why not just outsource to a software company - license Carplay / Android auto and focus on mechanical engineering and designing beautiful cars.

    I guess it makes it easier to tie people into an upgrade path.

    I guess you have to have a point of difference, when joe bloggs kia has carplay you would expect something better from a premium brand wouldn't you. The costs must be horrific to do it and the threat of being hacked would be a smaller footprint than say generic android but wow your name would be mud if it came out that somebody could get into your cars software with some simple hack, they must live in constant dread of that happening

  11. I still think you need to earth. you say there is no current from radiator but there possibly is, although the radiator is in rubber there is still possibly a measurable slight  connection to earth from oils or contaminants on the mounts or bolts. apparently its possible  even through the hoses if they are old and dirty inside it can't hurt to test after earthing the radiator anyway.

    earths are measured in ohms, not every earth will have the same reading due to differing connections, its a bit like jumper leads not all being equal in there ability to transfer current

    I don't think you can fully remove the current from the liquid so think your wasting time with all the flushes, having many different metals that the liquid is contacting is going to cause currents, liquid carrys a charge that needs to get back to the battery terminal, there is possibly a slight path through the radiator to earth that your tester isn't picking up, you need to be measuring the ohms from all your earths and radiator and you probably need a megger tester that applies a voltage as its testing not a simple probe tester.

    earthing the radiator makes it 0 ohms or dead in the circuit

    earths are a real science even in electrical gear especially audio gear but it shows as noise, BMW usually run earth circuits but there were earth points scattered around my e39 from taillights etc and wires that go brittle inside the boot lid flexi rubber hose can  cause all sorts of weird faults in e36

    some people in custom cars earth the radiator, the cap and even fit an anode inside that is designed to rust away saving the radiator and is an easily replaceable part, a bit like they do on aluminum  boat propellers , you replace the anode not the prop.

    does seem an odd fault but it doesn't happen that bad to all so it seems a bit more specific to your car, good luck

  12. you need to check and clean all your earth connections throughout the car, a decent earth and the current will pass through the metal and not find its way into the fluid in the first place, they recommend to test with engine off, again wit it running and by switching on accessories one by one looking for voltage spikes. Something like a big stereo amp in the boot not having a good grounding could be letting they stray currents out to find an easier path to the battery which in your case is the liquid which is conductive

    anything over .3v will destroy a radiator, and some ali radiators come with a ground wire so you could try that


  13. hose clamp was a 5 min job with a piece of broken hacksaw blade, done  3 now annoying but understandable from a factory perspective, was more annoyed at having to cut and solder/heatshrink  the new flying leads off the old pump so the connector was correct on the new ebay a pump

    One thing I will agree with is that these platforms need to be more regulated and the providers held accountable for what their algorithm is doing. 

    Probably won't happen though as these make money, and cash is king. 

    I think the whole current trump twitter facebook thing, they will lose their "were not producers argument" and then will be held to the same legalities as print and tv, ie sue able

    they are so obviously producers, so not before time

    the only thing I learnt/considered from that doco  was that it wasn't so much a conspiracy but more the intentions were good but they opened pandoras box and the AI just overtook them, They never expected a like button to be so powerful at the time. they are constantly scrambling now trying to appease people to keep their business model going

    Anyone with half a brain should already know what social media is doing in the background, nothing in The Social Dilemma should be a surprise these days. I didnt find it that scary, nor did it make me want to delete all my accounts.

    yes nothing new any adult with half a brain didn't already know but I do feel concerned for the young ones that don't know a life before S media, its the drug like habit control over your life that they will not have the experience to combat. AI is only going to get better at catching you


  16. exactly,

    I thought auto coolers were for those people that tow large weights etc not idling in traffic.

    a large percentage of  the manual cars for sale in Auckland have a clutch shudder from excessive overuse and people slipping them to creep forward.

    to be sitting stopped on the north shore entry to the harbour bridge moving one car length if your lucky in a manual, how unnecessary

    if your sitting through two green light changes on a hill, say at the top of queen to get into K road, you can muck around with handbrakes probably behind a bus so nill vision, many possible oh sh*t were not moving, oh hang on were off, no wait, hill starts 

    or you could just sit there in an auto completely relaxed,

    its a no brainer, traffic is stressful enough without torturing yourself unnecessarily.

    not that any manual lover would change or admit any of that

    I'd also like to see these owners manuals that don't recommend leaving an auto in drive, altho you underlined it so maybe its true, can't see the fuel difference between your manual in neutral and said auto either, engine is still running in both cases, oh wait autos have start/stop now, do manuals have that too?

    and if you flicked your manual into neutral as you suggest and coast, thats an immediate fail of your drivers license test. you don't have control of the vehicle,

    your argument is questionable
