Hi roger, but chipping can and does alter a particular engines efficientcy. Ala more fuel pressure. ? the basic thing a remap or tunning box does is alter/ raise injector pressure, amoungst other things.So making for a more full burn. ie raising effientcy.....So einsteins theory on this particular subject does not apply, because his therory is based on 100% effientcy, which both petrol and diesel engines cannot a achieve.once they can, then you would be correct and remaps and tunning boxes would be a total waste of time.......RogerL said:
Seth, I can't match Einstein's knowledge so I just work from basic science - where calorific value is common in work involviing energy.
I also try never to mis-spell people's names!

Einstein's rules are absolute - the fact that all engines need an efficiency % factor applied doesn't disprove Einstein.
The reality of chips is that it's impossible to find any published PROPER test of fuel consumption, eg repeating a EU standard test after chipping.

i think roger, if you care to buy the right magazine, something like diesel car or is it called what diesel car now? they have over the years done proper test results of before and after,of course they are not proper Eu standard test,ie simulated,but are actual on the road day to day results.as have other publications.but then einstiens is merely a therory regardless [not proven a bit like eu standard testing really]... yet . upping the injector pressures to improve efficentcy is an absolute scientific fact....
At this point, I'll bow out - and go and tell all the powertrain engineers around the world they're wasting their time and money because a cheap box can work miracles!JonnyG said:
i think you will find they wont be using any einstien therories,but will be working as always on better effiecentcy,ie upping injector pressures,amoungst other things,and sacastism because you dont like my answers changes nothing,and doesnt hide the fact that nobody has made any claims of miracles, from anytunnig box or remap!!RogerL said:

Perhaps not directly related to the thread but as one of my illustrious predecessors' Albert Einstein has been mentioned let me say that he produce a number of theories, but his most quoted ones are 'relativity' and 'special relativity' which brought forth the E = MC2 equation.
I can assure all correspondents that it can be applied to engine performance and it does take into account the relative efficiencies even if they are less than 100%. I am not about to detail how the subjects converge, far too high brow and largely irrelevant to this topic.
Engine and software designers are only expected to user humbler normal rules of electronics, thermodynamics and mechanical engineering will suffice. That does not mean that Einstein does not apply, just that it is not necessary to consider such matters with that degree of detail.
However Albert was far more pragmatic than just that, one of his less well known quotes is:-
"No amount of experimentation can ever prove me right; a single experiment can prove me wrong."
A sobering thought for all of us who think we know best!
It may be of interest, that the particle physicists at the large hadron collider at CERN have been searching for the Higgs Boson were also looking at neutrino's and some results have raised questions about the speed of light being the maximum possible velocity. To balance this though the results that raised the possibility are being scrutinised very carefully. If it proves to be true, then Albert's will have to turn in his grave.

The latest Mazda diesels are now a much lower compression. Now 14.1 (sorry mistook the figures for compression, still worth reading)

Yes i read of Audi showing a lot higher output as well, that's why i always say a rolling road should be used before a remap, and after.
To establish any ACTUAL gains.
Hi ray,yes compression ratio is not to be confused with the stiochometric value which after all is just mixture.Compression ratio,s started dropping 10 years ago because they can.Fuel pressure has increased and made up for it.Fuel injection timing has now become ******** to.15 years ago the average was 15 degrees before top dead,now it is top dead.(firing stroke)
Roger L i apologise to spelling your name wrong totally unintentional.To me it sounds like it has a d in it.My mistake sorry.Please look at this website.Steinbauer uk.
If you,ve never used either you,ll never know.I could write a book about common rail and its benifits without consulting wikipedia.The scope of common rail is unbeilevable.

It's enlightening to read some of the proper re-map websites and their view of external chips.
