Have you never known a manufacturer buy a generic computer module with generic code and then modify it to make a product? It happens all the time, I have even done it myself for projects on SystemX.
And you are still waiting for your cheque from Google and Home owners club? Brian
I just get one sentence on the web site. is it a graphic? Brian
Use of brakes depends on the driver and traffic conditions and a good driver wont use the brakes much on a diesel or an electric car. A poor driver will use the brakes on either so it depends on how good the system is on overriding the mechanical brakes and using regenerative brakes instead.
That link more useful and accessible, lots of convoluted links though, which are a pain when you have to wade through them. Sounds to me like a kind of recycling of the exhaust to try to make other components instead. Anyone know what exactly the new exhaust artefacts are? Need to be wary, as we have been burned before with cfcs etc when a new problem came to light. Brian
A question that is addressed at the foot of the article I gave a link to. The assumptions made are that electric vehicles produce no particles from brake wear or engine emissions. However, because electric vehicles are heavier (14.6% to 28.7% according to the article) than an equivalent IC car they produce proportionately more particulates from tyre wear, road surface wear and the resuspension of road surface dust.
I thought the figure for 'dirt' from tyres etc. as a percentage of total 'dirt' was something like 25% to 30% in places like London.
by designing it properly
It used to be that suppliers made a profit centre out of "programming" devices for each specific customer (I've had many a boring opportunity doing this, offered to me down the years), but customers hated the product lock ins that that approach created, and would switch to a self programmable device like a shot if an alternative supplier made such.
so eventually everybody has to make self programmable devices to remain competitive.

A new set of tyres every four times I fill up?
Just how many doughnuts do you do when you drive?
Diesel cars have used exhaust gas recycling for several years, is this just a tweak to that?
All these "eco" tweaks do give more things to go wrong later, EGR valves get gunked up, particulate filters can get full of ash if not given an Italian tune-up often enough
Really? So Joe Bloggs can re-tune his diesel VW using his mobile phone? Sounds rather flawed to me.
It beggars belief that VW could have modified a Bosch product without Bosch being well aware of it.
Fantastic. Where are the actual statistics? As soon as I saw "could be" in the article heading I didn't bother to read further. My response to Dennis was because he stated that electric cars produce more particles per mile than similar sized diesels.
In the original study referred to in the link I gave.
The study covers the period up to 2035, using different models of vehicle development. That means that there are varying results, depending upon how the vehicle fleet evolves. However, none of them show an increase in electric vehicles producing a reduction in particulate emissions.
Which is true. 90% of PM10 and 85% of PM2.5 come from non-exhaust sources. Thee proportions will increase as exhaust emission controls become tighter. Non-exhaust source emissions are proportionate to vehicle weight and, in general, electric vehicles are heavier than the equivalent IC vehicle. The result is that they produce more particles than the equivalent diesel cars. The information is out there, if you bother to look.
I still don't buy it. To me, it all seems like a pinch of fact for a very specific circumstance used to generate an alarmist agenda. Where have I seen this before?
Yes they can remap their engines, but maybe not by their phone. They probably don't need the phone as some ODB plug in devices can remap the engine on their own.
Why? You buy a Compaq PC and can modify it if you want, HP aren't going to know or stop you. They even provide manuals to tell you how. Why shouldn't the computer in a car be sold to manufacturers in the same way.. here it is with the basics, change this and this if you want.
Don't waste your time on him its jws trolling.
Not so. ODB is by definition diagnostics. It is not designed to re-programme mapping. And to get the software which allows you to re-map (for a newish car) is not necessarily that easy. Let alone writing special software to fool government testing.
I really don't think you understand the close relationship between a car maker and their equipment suppliers. Ah well.
No, I don't think it means that. Vehicle manufacturers that use Bosch engine management systems - '(Bosch) is prohibiting technology that recognizes test cycles and its products aren?t allowed to be optimized for test situations anymore'.
I think the truth of that will come out eventually. I'd imagine there was some sort of licence that governed use, if only to ensure it worked as designed. Whether the terms of any such licence were broken, or whether anyone in Bosch knew about the precise nature of any tampering/modifying is difficult to say.
But yes, I'd agree - knowing at least about the possibility to 'tamper for gain' suggests somebody knew something.
How do you think manufacturers update the software if not using the ODB port on the car? One of my neighbours had his car stolen because you can reprogram stuff over the ODB port. They smashed the window, plugged something into the port and the car started and away they went. About 90 seconds start to finish and they didn't have any access to the keys at all. You can get the devices off the internet if you know where to look.
I don't think you understand the concept of devices that are made to be customised by someone other than the manufacturer even though they are common.
