Fuel efficiency remapping

EdGasket

remaps are usually done for power and work for that but are unlikely to produce a noticeably more economic performance even if thats what you want. Plus by the time you've paid extra for insurance on a chipped car (insurer will assume you're a speed freak), you won't save anything.

Can't have it both ways.

You said that the remappers were multi-million pound businesses, definitely not one man in a shed. You named four businesses to prove it.

Two of them turned out to be the same company, and then there were three.
Two of those turned out to be far smaller than multi-million pound.

Now, tell me again about these 25% reductions in 0-60 time and 21% improvements in economy/34% improvements in power/17% improvements in torque that are apparently COMPLETELY beyond the wit of manufacturers with thousands of highly qualified engineers and huge development budgets with millions of car sales depending on the results...?

Let's not forget that we know that these manufacturers - global corporations with annual profit in the billions - are willing to actively break the law to gain improvements of a fraction of those being claimed from one bloke in a shed who owes a shedload, or a business still run by the wife of the bloke who founded it 40 yrs ago and whose net assets wouldn't even buy one of the cars they map?

Just accept the fact that you are wrong and leave it at that.

Mmm.

Facts and reality can be so inconvenient, can't they, when they interfere with your feel-good over having splunked a few hundred quid...?

I went with Bluefin hand held map for an Audi a6 diesel,was looking for the extra torque etc,not too bothered about economy,supposedly took me from 134bhp to 167bhp,not had this checked but can feel the difference.

For clarity, I have absolutely no doubt that it's very easy to remap turbocharged cars for impressive percentages of extra power and torque...

<looks at thread title>
...and if a vehicle starts so underpowered that it's having to struggle and be thraped to maintain decent progress, economy can benefit from that extra power, too.

Seems we've come along way from the initial title.

So what exactly do you have doubts about?

Ok what about the car manufactures that offer the same engine in 3 states of tune? Small companies like BMW, Volvo. Ford etc? Do you know what the difference is between these engines?

Quite a few manufactures offer cars with a full warrantee when remapped by a tuning partner with higher bhp. Perhaps they are all involved in a conspiracy and you are right.

Uh huh. And i've no doubt all of those are multi million pound turnover business.

And frankly, if they're not - who gives a !!!!? Other than you who clearly needs to "win" an argument on the internet.

DMS are big players in the remapping world. They've been at it for nearly two decades. They are recommended by many motoring groups and forums and they do produce significant gains in performance.

If you chose not to believe that, then you are going against many many reviews and opinions based on actual experience.

Firstly, i didnt quote those figures. But heres figures i will quote and stand over.

Both of my 535d BMWs. Remapped. Both up from around 280BHP, to around 340BHP. Both had 0-60 times dropped from 6.5 odd seconds to around 5.5 odd seconds.

Heres one of the many remapped 535d videos on youtube to demonstrate this...

Frankly, i find it BANAL that you dont accept that remapping is a PROVEN technology? Are you in the flat earth society too? :eek:

This isnt difficult.

Manufacturers produce engines with certain power to meet certain emissions across global markets, and to ensure that the performance V reliability ratios for the company bean counters are met and to use as much shared components and ECUs as possible.

Get in to the computer, tweak the parameters and you can easily improve on performance.

This has been going on for DECADES. I first did it to my 1999 Passat 1.9 TDI.

Subaru owners were doing it from when the WRX came out in '92 or thereabouts.

Do you not think that SOMEWHERE along the line, of all the hundreds of thousands of modded cars out there SOMEONE would say "!!!! lads, my car isnt any quicker" if you were correct???????

Its the modern version of what John Cooper did in the early '60s - increase fuel / air mixture and you improve performance.

I dont see why thats so hard to grasp?
