[Closed] Anyone had a vw t5 remapped from 85 to 120hp? Thoughts....

How to make a filthy diesel filthier. Are you going to get one of those "eco-terrorist" stickers for the hatch?

Is this you George? 🙂

For a self confessed reformed eco terrorist your quite the condescending righteous edukator. Reminds me of the old joke "how do you know someone a a vegitatian"...... "Don't worry they usually tell you before you know their name "

I’ve got an 04 transporter, and have it booked in for a remap to 120, worthwhile? It’s used as a car really, but I just find it a bit sluggish on hills

now thats a worthwhile response !!! knob .

My 85hp T5 is dire , my 150hp T6 is ace. I keep meaning to get the T5 a pendle remap to 137hp, apparently it's a revalation.

They take 137 no bother & the dub hedz swear by pendle.

Get the biscuit tin out

And still getting 4 mpg more than before

Mines an 88 running 160 with a map. 160 is about the limit for the 2.0 CR engines, not sure about the 1.9/2.5.

Well we've all been aware of wasting non-renewable resources for as longas I've been alive (so yes trail rat, I was aware of the waste when wasting). From the mid-80s we've been aware of greenhousing the planet (so I stopped) and for at least 20 years we've been aware that diesels chuck out toxic NOX and soot even when perfectly set up to keep it to a minimum. And if you eliminate the EGR and over-fuel for more power the NOX and soot go up exponentially.

So if you want to poison your fellow citizens faster than necessarily and disproportionatley more normal, remap. And as it's local pollution you won't be poisoning Brazilians, Chinese or Indians, you'll be poisoning you friends, family and neighbours.

Remapping is selfish and anti-social.

Yes but I can get to places quicker.

Selfish and anti-social reasons.

And I doubt it given the trafic conditions in the UK. Even if you can it doesn't justify poisoning people.

So tell me again how green solar panels are .

A hell of a lot greener than burning diesel. Perfectly recyclable (Solar World panels) repay the embedded energy in a fraction of the life of the panels.

Once you're born you pollute, that's no reason to pollute gratuitously when you don't need or have to. Consider the air quality if everybody remapped their diesel, it would rise to Mumbai levels. So don't do it.

You make the assumption that all remaps are equal and all employ the same processes.

Mean while solars ok because all the pollution that goes into them(offsite mining and manufacturing process) is not on your door step.

The remaps generally get more MPG for the haters !!!

So you only argument is that as solar panels result in a tiny amonut of pollution which most poeple would regard as a justifiable alternative to going back to wood and stone age then gratuitously polluting with a remapped diesel in places with high population density is also OK.

It's not Trail Rat, remapping diesesl is dirty, selfish, anti-social and contributing to prematurely killing your neighbours.

Mpg is not the part that's got his goat up.

Mpg is only part of the equation

But he wrongly assumed all remappers are irresponsible egr &dpf removing dopeaddicts who are gluesniffers .........

No some of them leave the depollution gear and then just play with other parameters, mainly over-fueling but also timing changes and air flow which raise combusiton temperatures which raises NOX and kills asthma sufferers.

Did you not follow the VW cheat saga at all Trail Rat? Manuafcturers would love to produce more powerful drivable diesels from the same base unit because consumers want them. But they can't because doing so sends NOX 10 or 20 times over the NOX limit.

Only thing to watch is the insurance hike - you'll need to declare it.

Diesels are easy to remap and if done properly will give you a better driving car, that you might not need to floor it as much ? - remember the manufacturers play silly buggers with mapping to get emissions in check - but we all know real world driving isn't the lab test, so do it...

so do it...

Poison people. selfish and anti-soicial.

Getting your current car remapped is probably a greener option than getting a new one. Amiright?

OP.

I did exactly what you're thinking of (07 1.9 T5). Result was brilliant, much safer to drive (overtake) and better MPG.

Had it done 3 years ago, no problems since (30000 miles later). I'd go for it.

No i did not because Vw are about as interesting as paint drying.

How ever I do know certain land rover models are the same block injectors and turbo it's just the tune that differs between the outputs. So it's perfectly possibly on some vehicles to retune without killin baby otters assuming it's done responsibly and not by a 1 map fits all mob.

Still the best way not to kill people is not to drive your car regardless of its state of tune or size of the batteries

Doesn't the dpf colllect the extra soot the new map produces??

Lol get a * grip. As if one car (or every single car in the UK) makes any difference when China/India/Brazil etc are burning the * out of fossil fuels.

A big chunk of CO2 emissions comes from transport, and a big chunk of that from cars. Just like yours and mine. So it counts.

Maxtorque is the man to ask. His views echo those of Edukator and he was more forthright in expressing them when questioned about it.

A remap probably won't make your emissions any worse though when you aren't booting it.

Had my 1.9 done by Pendle (via TH Performance). 84 to 136bhp on their rolling road, sinilar jump in torque but I can’t remember the numbers. Will try & find the email with the graphs in. Insurance went up by £30.
Big difference in drive ability, less dropping into 4th on hills etc. No real fuel economy change.

A remap probably won't make your emissions any worse though when you aren't booting it.

Anything that reduces (or more commonly eliminates) exhaust gas recycling relative to fueling and air flow will increase NOX emissions even at very moderate throttle openings. I challenge you to find a remap that proprtionally increases exhaust gas recycling, Molgrips.

And I doubt it given the trafic conditions in the UK. Even if you can it doesn't justify poisoning people.

When I'm "making progress" I'm the fastest thing on the road.

Next time I try and influence someone’s opinion at work I’ll try this patronising and sanctimonious approach.

I’ll report back with results..........

Astravan? 🙂

No smoke. No poke.

Nope, wood fired are out as they cause harm to health through smoke particle inhalation.

Not sure how he’s powering an internet able device. Potato battery from the organic allotment?

This is hilarious; your wood-fired generator/alternator to charge your phone/computer to post here must be a marvel.

Our solar panels produce a lot more than we consume.

If you know there's a problem don't be a part of it. If you don't feel guilty about your exhaust emissions perhaps you should. Society has rules and sets standards, sometimes for the good of us all. If you stick to the rules then you are contributing no more than your acceptable share, do better if you think the rules scociety sets are too lax. However, willfully making your car produce more filth is plain anti-social.

Ok, on a purely technical tangent:

Remaps increase the fuel and air delivered at any given throttle opening. But power is proportional to fuel and air being burned in the cylinder. So to travel at a given speed you only need a certain amount of fuel and air.

Reducing EGR at low load wouldn't do anything for your performance, as far as I can tell? It might reduce your smoke and increase NOx, but I don't think it would increase power. But even if it did the driver would lift off to travel the same speed, so you'd end up simply recalibrating the pedal effectively.

Remapping increases the maximum available power when your foot is down, but driving along at the same speed requires the same power whatever your engine map.

I am not an engine mapper though so I could be wrong.

Oh and Edukator is right. You cannot simply avoid all responsibility by pointing at other people and say 'well they're worse'. It doesn't work like that. I have to explain this to kids.

Last time this topic came up it had similar reactions both ways unsurprisingly. At the time I had a T5 2.5 van for work which had been changed from 130 to 174 power. The query I had was that VW made both variants already with the same engine, mine was changed from one to the other, it was regularly serviced and run on posh diesel to maintain efficiency, don't drive like a nutter. The extra torque/grunt was handy for load lugging and mpg improved slightly too. Engine working less hard? Would emmissions be worse? Not sure. So it seemed a much better van to me overall but some views here did make me question whether it was the right thing to have had done and perhaps think of the bigger picture if the emmissions were in fact now worse (still don't know).

Latterly replaced that T5 with a T6 work van which is in as supplied power (150) with start/stop bluemotion technology (?), will continue with regular pattern of servicing/posh diesel and style of driving. Basically will leave this one as is, seems fine.

Had to work with someone driving a Euro 4 Transit recently. Walking round the back of the vehicle whilst the engine was running was grim, massively worse than for a more modern engine. As an asthma sufferer, voluntarily increasing this type of pollution [i]is[/I] knobbish IMO. Either put up with lower power or swap it for a more modern vehicle (preferably do that anyway!)

I assume the T6 has the urea injection (Adblu) to reduce NOX emissions. It's allowed manufacturers to produce more torque and not have sky high NOX in tests. They're still cheating in that real conditons test results for many brands clearly show they aren't adding enough AdBlu at high power (because that's not part of the test routine).

In theory at least recalibrating the AdBlu injection on E6 engines could allow mappers to produce less NOX than standard at the price of more regular AdBlu top ups.

We're ok to map our petrol cars though aren't we?

Predictable thread is predictable....

Dumb comment that adds nothing to the deabte from the owner of a Caddy concerned by the VW recall who refuses to have the "fix" is predictable... .

This may well be true, but no-one is re-mapping a weedy 85hp van or whatever it is in order to drive along at the same speed are they?!

Well yeah. You aren't currently using 85bhp unless your foot is on the boards, so why would you use 120bhp?

It makes overtaking easier, towing easier, and driving with load easier. I had an 85 as a hire van once, and it was proper gutless. I'm no boy racer, but I'd want 120bhp for those situations. But it only gets used for shorts bursts now and then.

Hiya,

On my 2015 Renault trafic I did a remap and it made a huge difference. I generally keep it in eco mode though and only use the full map when loaded and going up hill 😉 It gets a about 140BHP and more importantly an extra 50NM of torques.
However in eco mode I did note that I get an extra 3MPG so the engine seems to be runing more efficiently.

Crosses fingers

I read yesterday that Ad-Blu diesel engines actually emit [i]less[/i] NOx than petrol engines of similar power.

It's all jolly complicated.

By the sound of it, some do and some don't.

It seems that simply having ad-blue doesn't mean the map uses enough of it in any given situation. Didn't some people say they went from refilling ad-blue in 12k miles to 3k miles? So four times as much used?

The fumes from my T5 stink. Hopefully we'll see van's getting petrol engines or hybrids soon. They could certainly carry a few batteries that would make city driving more efficient.

Not keen on remapping as for one thing my van has done nearly 170k.

It's slow but I can live with it. Even if it had 130bhp it would still be slow. And it would still be a slow van. I ****ing hate vans. They have their uses but driving is one thing they will always be shit at so may as well put up with it.

Hopefully we'll see van's getting petrol engines or hybrids soon.

With more LEZ's in the future I don't think they have a choice but to develop them.

Nissan have an electric van. Always thought it was a great use case for city deliveries and work. Particularly London as even an hour's drive across the capital isn't that far in terms of miles.

Yeah, remember when car manufacturers made that revolutionary technological leap from tdi to commonrail so we could all enjoy massive gains in efficiency, mpg, power and reliability, and of course they are cleaner, so much cleaner. Only downside is you can't use bio-diesel in them. Sweet chip shop smelling bio.

Yeah, like the rest of the world were using, continue to use and will continue to use 😉

I **** hate vans. They have their uses but driving is one thing they will always be shit at so may as well put up with it.

Hang on I thought STW mandated van speak was that they are the ultimate vehicle and in addition to being the most versatile tool imaginable they are simultaneously classless as well as a subtle inference that you are slightly better off than plebs in their cars.
