Anybody reading this had their vans remapped ?
Reply with before and after stats e.g van year , engine , mileage , before and after readings.
Also how your van feels to live with before and after ..

When I had my 174ps done which is 171bhp in the uk it was mapped to 205 but that was a few years ago now, but it did produce more torque and I did have an increase in mpg due to not changing gear as often. The thing is you get used to it and want more.

Would high mileage be an issue when getting a remap ? Mines the AXD engine.
I don't know who to use to do it either there's garages and people doing it everywhere . I spoke to my local Pendle and they want £295 plus vat don't know if they got a rolling road there think they just get the remap back.
Also there's a bhpuk rep who wants £175 plus vat again they send the map off to the main garage with rolling road in Burnley .
Also and I know this is probably a no no , but a mobile remapper with a genuine kess master , which I'm guessing these will be already saved files but he does say he can tweak it ? For £150 ...

I'm just curious in thinking will this companies all use the same map which was done years ago and gets passed about ?

I had my van mapped not long after buying it, it's a 2013 2.0l D but was detuned from the factory to 84bhp. The main reason I got it mapped is purely because I went to Wales on holiday and struggled on the steep hills, so went along to Revo who mapped my to 170bhp. Driveability is massively improved, mpg hasn't really changed very much, at least nothing to write home about.
I would personally only trust tried and tested companies as a bad map can fubar your engine. Anything below £300 I'd be very wary. I went with Revo as they specialise in a few makes of vehicles, plus they limit the torque on my map as it's only a 5 speed box so full torque would melt my gearbox and clutch, that's what I expect from someone "tweaking" something on my car or van.
They didn't have a rolling road but that didn't bother me, it was purely a improved drive I was after, end of the day they are vans / campers not track weapons for the most of us, a few have taken them to another level though which is unbelievably impressive. If you're looking at spending circa £200 on a map then I'm guessing you're not going to aiming for 300bhp+ when you're done.
Boils down to why you want it mapped, and how much are you willing to spend.

Your van is alot newer than mine also mines a 06 .
Its a 130bhp at the moment . I am looking for an increase in that and torque hoping it makes it a bit better when driving at lower speeds . I don't know if I believe you can get better mpg without having the specs decreased .?
I'm just wondering if the ones who havent got a rolling road are just using the same map than most other companies are using , because they don't have a rolling road to know what to adjust .
So whether u pay £400 or £200 will it not be the same if there's no way to test on a rolling road

Revo plugged their laptop in and took the van for a test drive while it took measurements and recorded the torque vs engine speed. Myself and a guy from work had both our vans done, his was the 102bhp, our torque figures were very close to what they expect from a 170 map.
You're on about live mapping then regarding adjusting, a mobile mapper charging £200 would not do this, £200 map is a pre-written generic map for your engine code, he'll come out, plug in, 30 minutes goes by and he say "all done, see ya".
I'd rather pay a firmly established company that none throughout car moders and motorsport to work on my car even if that means paying more, because they've taken the time to make the maps safe. They also do a health check on the engine etc prior to loading the map, if there's any underlining issues (that you may not even know about) they'll pick it up and advise if it's a good to go or not. I would be surprised if a mm would does this also...for £200.
Actual tuning companies spend a lot of money on producing their maps, they don't just go online and buy and "off the shelf". I wonder if mm's have the funds to do that r&d and still only charge £200?
End of the day it's your van and your money, I would say 9 times out of 10 a map is an improvement, just do your research of the company / man in a van before parting with your money.
In theory you should get better mpg because say for example, joining a motorway you want to be at the speed limit as quick as possible, lower power means you're accelerating harder and longer ergo using up more fuel, in a tuned vehicle you'll get there quicker so can come off the loud pedal and drop the revs. This also depends on 2 main factors, driving style and engine performance.

Sorry, but the reality (as in the real-world physics) is not like that. And when you think about it, reality can't be like that. If it were, you would get the best MPG by simply driving everywhere with your foot flat to the floor!

Viewed simplistically, a vehicle should use exactly the same amount of fuel by going slowly from (say) 30MPH to 60MPH as it would quickly - at the simplest level you are doing the same amount of work. At that simple level, it doesn't matter if the engine is "tuned" or not.

But at a more complicated level there are a whole load of factors - some of which favour slower acceleration, and some of which favour faster. So for example, heat losses from the engine are likely to be greater when accelerating slowly (simply because the process takes longer), but waste heat generation under hard acceleration is likely to be higher because of extra heat losses in the gearbox.

If you really want to know about what types of driving achieve good fuel economy, there's been eight decades of experience gained during competitive sports such as the Shell Eco-Marathon (running since 1939). It's fair to say that 80 years of experience there shows that you do not get the best fuel economy by joining the motorway and booting it, tuned engine or not!

I mapped my van myself very easy to do got a map from Blacksmoke been on now nearly 4 years went from 102 to around 140 my van is a 1.9 07 plate and i have done 30k miles or so like this no issues runs and drives really well, cost me under 100 for the map and cable/software

I didn't say drive everywhere with your foot to the floor, that obviously would destroy your mpg, everyone knows that, I merely meant you're putting less strain and pressure on the engine to haul a vehicle along with more power so burning less fuel.
I took my 150bhp diesel astra which would see circa 38 - 39mpg and tubed it to 211bhp and would see 42 - 43mpg with same driving style. Surely power to weight ratios play a big factor in mpg too.
I'm by no means an expert on this or overly mechanically minded, just speaking from my own experience over the years. My astra once tuned had better performance and slightly better mpg, the van has better performance but I can't honestly say better or the same mpg. As I said before, it comes down to driving style and the vehicle itself.

Apologies - I wrote a long piece criticising just one small part of what you posted. I don't believe it's ever true that you can get better MPG by getting up to the speed limit quickly, but that was not the main point of your post.

Another way in which higher power can save fuel is that it can allow you to cruise in a higher gear comfortably at lower engine revs. It's one of the failings of my van - I cannot cruise continuously in 7th gear on the motorway, because it labours on even the shallow motorway hills, and I'm sure a remap would help.

And as you say, driving style is probably more important than anything. It's hard not to get accustomed to the extra power that you have available, and if that makes you use the power more often and go faster, you will use more fuel. Some people can control that and others can't. I know I'm the latter, which is why I haven't had the current van remapped.

Did you use the kess V2 master device they sell on ebay ?

Your van is a bog standard van with no engine mods then get a generic as it's an older engine now and the engine has had many maps by different mappers. There's no need for a rolling road print out as you won't get any more than 180 out of an axd because of the turbo restrictions, There's also many things to go wrong if you try and do your own mapping like crashing the ecu because of low battery voltage. For £200-£300 I would pay someone who's done it before. I found the best tune to be a real time road tune as you get real time loads on the vehicle.

Yea mine is just a bog standard AXD that's why I'm trying to find out is it ok to have one of the mobile guys do it like in the above photos I have posted if you've seen them , or will it be better go to a garage who are reps for bigger tuning companies ?
Im just after more torque for lower speed driving because it feels ok when I get past 40 but under that feels a bit sluggish .
Will a egr blanking plate improve throttle response a little ? And I'm thinking of replacing the boxes on the exhaust with some straight pipe .

A piece of tin from a soft drink would do the blank and blanking the vac tubes also as that engine doesn't have to have the egr mapped out. I can't remember now what the first map was other than it was done at Paramount performance in Slough but the second map was a road tune which was Quantum. I now have to use a full custom map as there's no one with the same hardware as me so no base maps to use. The thing with a higher mileage engine is carbon deposits through the egr and the back of the inlet valves as that doesn't help with air flow. Being sluggish could be down to the egr not closing correctly and may require a looking at and a clean whilst it's off. Even if it's blanked off the deposits will still be there and with it being a direct injection engine there's nothing other than air to clean the carbon up. How far do you want to go as you would probably want to get it checked on a road test to get some logs before you get it mapped. A map alone won't clear any faults you may have.

Will the tin from a can not be too thin and not be able handle the temperature? Also doesn't the egr help to prolong the life of your cat , helping not burn as hot ?

There is a quantum rep near me .

How do u mean faults , do u mean lights on dash ?

One thing i 💯 want to do is get rid of the intercooler system and replace it with pipe and jubilee clips be good if someone knew a link to someone who has done this themselves and not bought the expensive forge kit which still had the push connections.

Also can a engine with nearly 250k miles handle a remap ?
Are the parts on the AXD the same has the AXE like turbo injectors etc ?
So is the AXD just down tuned ?
The axd has the same injectors as the axe, the turbo is bigger on the axe and you may need the inlet elbow depending on if your current turbo is a KKK or a Garret. The clutch and flywheel is also de rated on the axd but an axe flywheel and cltch is a straight swap. You won't have any problems with 200-220bhp on your current setup but anymore and it will struggle. I made up all my own pipes as I can't buy things off the shelf ready done for mine as it's quite different now. A 180 bi turbo ic will fit yours and it means cutting the baynets off the ends of those pipes that connect to it, but it means those two pipes use bands to stop them coming off the ic.
