As usual, pslewis prefers to ignore the technical questions and spout misinformed rubbish whilst hiding behind the title of "Engineer". I've not taken any money for mapping for ages and will often chip in to threads and suggest people don't need a remap to achieve their goals. I'm not wasting my time further with you on a technical discussion because you just snipe and stir.
What a ridiculous extrapolation to take it to top level motorsport. I would expect to be able to drive a road car, possibly with well setup modifications, hard with trackday use and not find it excessively fragile - ie I do not expect to change non-service items frequently. There is a huge difference between this and F1 or WRC as you well know.
You don't need to look far for previous data I've posted on this. Data, not the opinions of someone that hasn't tried it and tuned their engine on it. 40 BHP was on a car that already had about 400-450 BHP - ie 10%, and this was using £12 (full bottle - high dose) per tank. Why do you think I got 434 BHP and 395 lbft out of a TD05-20G when many struggle to get 400 BHP? Why did I get the 121mph quarter mile terminals to back it up? You can get results from methanol or NF (at least the old stuff) that bridged a fair bit of the gap between normal fuel and race fuel to the point that some have run on it in competition where race fuel was an alternative. In the US where high octane fuels are more available you'll see loads of dyno plots of pump fuel and race fuel for any big tune over 350 WHP.
I'm bored now of reciting stuff that can be found through searching to people that aren't that interested in the answers anyway and just want to spread misinformation.

You seem to be such an individual
40 brake increase for £5.00 bottle, why dont I see threads with this all over the place, is it a closely guarded secret. I see a lot of threads wanting to spend £500 for a remap for a more modest gain from standard.

Example plot here I've previously posted. This spec was a TD05 on a standard UK engine mapped to its detonation limit with and without NF. The gains come from extra boost and timing.

It all depends on the way the person replys, to supply condescendence proof is all that is required. Again it is also how that questioner is castigate depends on friendly future discourse, thats all.
As for my mind it has always been broadened to new concepts, to chose to utilise them is a different matter.

john banks dont give this man your time.
just make sure everyone drives there car in a good manor and everything will be alright .forget what these cars where made for .forget these cars have a red line.IVE NEVER HEARD SO MUCH ****E FROM A PERSON ON A THREAD .
This man cant even except opinions from people from zen and john banks etc its amazing.
pslewis your have now been given the freedom of scoobynet .we now name you BSlewis .the BS stands for bull****!!

Oh so there was some 'devil's advocate' element to your posts, hope you weren't agreeing with Pete Lewis just for the bedevilment of it all. The last thing we all need is for Pete to think his posts are actually taken seriously . Anyway I think this thread has run its course hopefully it has been of benefit to some whilst enlightening others. As for Pete you know what they say 'you can take a horse to water .......'

I can assure you that if you know about it, they do!!
They do NOT do what you do for a reason ... a very good reason ...

Well only a completely uneducated idiot would write like you do .....
Example, "There car in a good manor" - should that be "Thier car in a good manner"?? Just a guess??
Go and do some english lessons instead of posting drivel on here!
I take it you are 14?

Stop having a go at all tuners Pete, some people want to push their cars to the limit, its a hobby to many.
I know you are highlighting the fact that their are people out there that have little knowelage and spout drivel to sell stuff they don't understand, but do appreciate that their are some good people out there doing interesing stuff. Then there are others who like to keep a car as designed.
This blanket attitude towards anyone who dares to change the standard subaru setup is annoying.

Thanks for the reply, it is appreciated.

This place gets worse
By the way ..... modify your cars, just don't come on here crying that somethings gone wrong - and don't blame Subaru!!
Subaru sell a fantastically reliable car ..... some destroy that car by changing it.
What I cannot fathom is why buy a car then change it????
Buy the car you WANT not one you want to change????????????????
Even the most **** and stupid MUST see the logic in that last statement?

Lets see the PROOF .... we've heard the **** bollox ... now lets SEE the specs and tolerance values and compare them to other mass market cars!
Easy and cheap to throw statements about - a bit tougher to PROVE you are not talking out your ****, and spouting what your mate said his mates brother said up the pub one day in 1999
So, figures please .... or at the VERY least tell us where you got your info from?
Come on, the common sense brigade are running SN now and we need facts not myths!!

Subaru engines appear to build very consistently. However don't think for one minute that just because 2 cars are the same model, even with the same mods, that they will require the same mapping. It's less pronounced on the later cars, but early cars are just so different. You can do a map on one car of supposedly same vintage and it will be way off on another car.
The MAF sensor makes things much closer than say a MAP based system, as small changes in VE are accounted for. But some engines have vastly different ignition timing requirements for no apparent reason. 97/98 UK engines are notorious for not allowing much ignition timing to be run. But every once and a while (say one car in 10) you will get one in that responds totally differently and makes power much more easily.
Within the confines of a standard car, with a standard map, cars can run very similarly. If you want to push the car to the maximum that the current setup would allow (standard car for instance) then the differences would become more apparent.

I find that very difficult to believe ... but, if you say they do and have hard evidence - then I suppose each car has it's own mapping in it's own ECU.

Not at all pete. I am saying that Subaru map for the lowest common denominator. And that changes in overall airflow (for the same boost and RPM) will be accounted for in a general sense by the MAF sensor. On the newer cars each car can be mapped individually to a certain extent by the very active ignition timing. The further you go from standard, the greater the differences become.

No actually I am talking from experience of mapping my Civic Type R and then looking at other cars data logs with exactly the same mods running the map I had created. You would be suprised how different the fueling and amount of ignition 2 identical cars will run.
I don't need to know exact tolerences to know that two seemingly identical engines are obviously not totally the same.

And surely someone wanting to improve their English would take some English lessons rather than do them.
Uneducated idiot?
