Technical Engine remap

I've driven diesels for years and it's not about to change any time soon.

People moan and complain about the environmental costs but it's usually more and argument of health than environment, as environmentally diesels are now no worse than petrols, in addition there is a growing faction who want tighter controls on petrol cars and I expect to see petrol particulate filters becoming standard in the next few years.

Let's all be honest here, the fossil fuel burning cars are in their dying days. Since the diesel gate scandal the focus is now very much on electric cars and hydrogen has now started to creep into the mainstream.

You can buy a tesla and drive across Europe taking no longer than a petrol and topping up in 30 mins at one of there free to use charging stations every 200-300 miles making owning an electric car easily with in reach of many. New tesla models will come in at £30k soon and tesla give free reign to any other manufacturer to use their technology free of charge in their own models to proliferate the expansion of electric car use.

I have no interest in petrol cars now, just as dirty, burn more fuel and cost more to run as well as usually lacking guts compared to an equivalent diesel. Give me a 2.8second 0-60 electric car that will do 300 miles on a charge at an affordable cost and I will happily bin the diesel.

Fortunately that day is coming soon
 
Current generation diesel buses and lorries use a different type of emissions control technology and are, perhaps surprisingly, much cleaner than most current generation diesel passenger cars.
Hopefully the real driving emissions (RDE) testing that applies for new models from September 2017 and for new vehicles from September 2019 will result in much cleaner passenger cars with diesel engines. Simply switching off EGR at all loads higher than those that occur in the NEDC will no longer be an option.

Or kill them off? once real world testing comes in it will show just how bad diesels are(OK petrol's too, to an extent) and I bet the tax on them (Diesel) goes way up?
 
I pass Glasgow central on foot going to work twice a day and the black hacks sitting waiting with engines running, the fumes are terrible and from some of the older busses,lorries and vans. So don't think diesel car are main culprits. Maybe they should kill off fossil fuels altogether and go with hybrids But would need to be heavily subsidised.

Hybrids without fossil fuels?

If we would completely switch to biofuels, then lots of people would starve.

In my country plug-in hybrids are popular because of the lower taxes, but hardly any owner uses the power cable to charge the batteries. These plug-in hybrids are mostly used as petrol cars with a poor fuel economy. Such tax advantages only result in more pollution.
 
But would need to be heavily subsidised.

I'd say it's more likely that those folks who wish to use personal transport will in future have to give up a significantly greater proportion of their income in order to do so.

In most cities, there are viable alternatives; in rural communities, there may not be. So IMHO we need a transport policy which reflects that; if we are going to impose additional fiscal measures on motorists to combat pollution, the measures should be targeted at the most polluting vehicles in the most polluted locations.

Right now, that means older diesel buses and trucks, and the vast majority of diesel cars and light vans, irrespective of age, operating in densely populated areas.

Manufacturers have put the proverbial two fingers up at the regulators by continuing to produce diesel cars which meet the regulations in testing but have abysmal real world pollution credentials; I doubt those vehicles will ever meet the emissions targets they were supposed to be designed for and for public health reasons need to be banned from cities as a matter of priority. Those who bought these cars are the innocent party; indeed, they were incentivised to do so. If the innocent buyers are to be compensated or incentivised to switch, IMO we should first look to the manufacturers to fund that compensation.

As stated by AGH1965 one issue with hybrids is that on non stop-start journeys they actually use more fuel than an equivilent non-hybrid because of the weight of the electrical equipment. Even pure plug-ins cause polution because the electricity has to be generated. As they become more common we will also see more issues with battery accident and disposal hazards. I looked at a plug in electric a year or so ago as work offered 50% off and free charging on small car on a 3 year lease. Unfortunatly even with that subsidy (and the availablity of a second petrol car for long trips) my Croma is significantly cheaper to run even if the purchase cost was fully written off. Diesels were pushed to reduce global polution (CO2) but have had an adverse impact on local polution (particulates and NOx). These are being addressed with DPF and SCR (many current model diesels have this and topping up AdBlue is no harder than oil or screenwash). People say cycle (I don't) or take the bus (2 walks, two buses and an hours travel time compared to 20 minutes in the car) but it's not really practical for me.

Topping up isn't hard, but if SCR technology would be used properly on cars, then most users would get frustrated. Modern trucks have an AdBlue tank with a capacity that is up to 5% of fuel tank's capacity. That has a reason. You need quite an amount of AdBlue to get rid of the NOx. If applied on cars in the same manner, then filling AdBlue can't be compared with screenwash or oil. Instead you should compare it with refueling.

Modern trucks have an AdBlue tank with a capacity that is up to 1/5 of fuel tank's capacity. That has a reason. You need quite an amount of AdBlue to get rid of the NOx.

Trucks use a LOT more fuel and AdBlue than a car. On most cars it's filled up at the service and the driver might have to do it once or twice in between depending on car and driving style. It's certainly not every fill of the fuel tank. The AdBlue / fuel ratio is 4 to 10%. See

Cars don't need much AdBlue now, because at this moment the NOx emission is only important at the low load conditions of the NEDC test. The coming real driving emissions (RDE) testing will lead to much higher AdBlue consumption though.
 
Reference? Common sense. If the NOx emission during all normal driving conditions becomes important, then the SCR needs AdBlue in all these conditions. This will likely result in an AdBlue to fuel ratio that is comparable with that of modern trucks.

Oops, I meant to write 5%, but I didn't.

Now I understand much better why g8rpi responded the way he did. Sorry for the confusion.

However, even at an AdBlue to fuel ratio of 1/20, you still need quite some AdBlue between two services. With a service interval of 18000 miles and a fuel consumption of 56 MPG, you need more than 70 litres. So, filling AdBlue might be as easy as filling screen wash or oil, but I would be really frustrated if my car needed more than 70 litres of screen wash or oil between services.
 
Well the tuning box finally arrived today from Poland, not Germany. After a lot of swearing and cursing and head scratching I finally got it fitted. I have decided that the 500 is a pig to work on, and the connectors are placed awkwardly and even upside down that the are difficult to remove, lost one of the screws that holds the pipe onto the air box in the engine somewhere that even bouncing and eventually a bit of brake jolting it still didn't fall out, so will have to order a new one . On a positive note the car goes like stink now and I would say is quicker now than the 95 bhp Corsa cdti that it replaced. It say's on the box it can give an extra 30bhp. It certainly isn't sluggish and hesitant any longer and I accidentally did a wheel spin pulling away from the lights on the test run. So it has saved me £210 on the price of the ECU remap. So now the car drives how I expected it to. Thank you Kekybobo (Tom ) for you help and suppling pics and info of where to find the tuning box on eBay.

If I was to travel by bus to work its 2 hrs on a dirty smelly 10 year old bus to go 8.5 miles with even dirtier smelly people( on the whole) and is £8 a day, and I can gladly say to the diesel haters, hell will freeze over before that happens.[emoji35
