That reminds me, I changed the type of tacho as well in the end. 

These things (Smiths RVC tachos) are very variable and a law into themselves. I had to make a “coil emulator” using a relay coil to produce a sufficiently spicy output to reliably trigger the 6 pot one in the Vitesse. The RVI version is a bit easier. Just connect the coil pack supply through it and it works. Should probably add that the EDIS6 does not have a dedicated tacho out pin which I believe the EDIS does have. So I use the so-called diagnostic out which is possibly even lower voltage than the dedicated tacho out. Possibly the MJL box has a tacho out function as well?

Indeed. And Labradors are not noted for their risk assessment skills…. (Or even brain cells)

Not least because it’s barely reported. Likewise Yemen. On dust explosions….. in the early 2000s there was a bit of a trend for sludge driers among the waste-water companies. This to turn dewatered “cake” @ ~25-30% dry solids into dry pellets at >95% DS. All very costly and my then employer made good money selling large pumps to move the very viscous sludge cake around. Two problems though. Apparently no one considered that dried poo dust might be explosive. Even though “solid fuel” was one of the purported uses*.  There were a couple of explosions, one of which killed a man (Nash, Newport). This meant that several plants in the commissioning stages had to be redesigned to mitigate this “small wrinkle”. The next big problem was that nobody had apparently done the sums on what the energy needed to produce the drying effect might cost…. So almost none of the plants ran beyond their initial commissioning/handover period. *one of the other claimed uses was as an ecologically sound fertiliser for home/garden use. And it probably was fine fertiliser (heavy metals etc aside), certainly the drying process sterilised it. It didn’t even smell bad…… while dry. But when wet (and plants need watering), the smell returned with a vengeance…. Not many repeat purchases!

None….at…..all.  “Necessary to tuck under the bonnet edge to reduce drag”. I call BS on that though as both A6 and previous A90 (both famously slippery) managed this without this pesky compromise!

Makes no odds to me! Carry on Chaps. BiTurbo228, my friend says the designs are on his old work laptop, he will check when he goes back, hopefully next week. And yes your summary is accurate I used a factory mx5 friction disc and a factory release bearing. Also a custom flywheel with a spigot in would be a very nice solution and save some over complication. My bellhousing is shortened around 25mm

It does work. It doesn’t leak. However, it’s slower to cut in and cut out than the original and, in spite of the marketing puff claims, no quieter*. Possibly I can influence the switching performance by changing the pre-charge pressure in the accumulator. This has 12psi marked on it, though the book says 18psi. It measured at 12. The original was 8psi and seems to be a sprung one as it has no valve. *quieter than the old one was immediately prior to removal due to rough bearing(s) but not the old one in healthy state.  

And guesses for how many f#### given by the designers. You do wonder if these people exist in some sort of parallel universe. 

That post and the various virtue signalling posters and flags in the windows of the newly 'alternatively trendy' streets near where i live got me thinking about reactions to such events. For example, the slaughter in Sudan is truly appalling and tragic and yet strirs barely an eyebrow. While the neverending lethal bickering of the Levant for some reason seems to soak up all the attention of the (self proclaimed) 'caring classes'. I have pretty much lost my ability to care for the apparently unsolvable, and in my view by now mostly self-inflicted great ills of the Middle East and Africa. However, the recent events in Crans Montana somehow strike a chord. Possibly because it was because of  fire and possibly because it was so many young people.  But either way and unlike Sudan, Gaza, or events nearer to home but now years past it seems too early for a throwaway. But that's just me.

Uh huh….. but not if your wipers are iced to the screen or you are trying to avoid ruining them by scraping them over ice. Design FAIL!
