Title: Retuning the ED30
Post by: stealthwolf on May 14, 2010, 08:28:37 pm
Everyone talks about how the ED30 is a detuned S3 lump. Has anyone retuned back into an S3? And then remapped it?

Any links would be welcome.

You been at those sweeties again, Jaz?

Why detune (demap) and then remap again?

Indeed why? Unless I don't understand the question? Same engine so have it 230bhp, 265bhp or 300bhp stage one?!

Drop the bag and step away from the stall!

Not detune but upgrade the internals and remap.

Its the same apart from the intercooler.

The internals are pretty much the same Stealth.

Obvious differences are cams, compression ratio (I think), intercooler and map.

compression ratio is the same, and I think the cams must be.

Out of interest is the DSG gearbox in an S3 and a GTi/ED30 exactly the same?  I assume the clutch is upgraded for the 4-wheel drive S3.

Am i right in saying that the DSG gearbox found in VWs, Audis, Seats, etc. is an Audi originated product?

I was under the impression that the cams were different and the compresion ratio on the S3

The Ed30 engine is NOT the same as the S3 engine . . . this has been thrashed to death, and proven before.

....How much time have you got to read it all? All weekend?

Both 'sides' post some very convincing arguments why they are each correct.

As far as I know, the DSG box of tricks (and therefore clutches) is the same in each of the GTI and Ed30. S3? - I dunno.

Somebody who works for VW/Audi must know the conclusive answer.

So the S3 engine is superior then if they are different?
Title: Re: Retuning the ED30
Post by: mackit on May 15, 2010, 10:15:32 pm
I think most might agree that the combination of the power output and the 4-wheel drive system is pretty hard to compete against.   :notworthy:
Title: Re: Retuning the ED30
Post by: Nasir on May 15, 2010, 10:21:08 pm
Oh I know that, I mean just the engine. If it's different, how? And how do they both re-map to the same figure? (or am I looking at it too simply?)

until you are on the track (in the dry) when the lightness and balance of the ed30 will be superior (power nothwithstanding), all that 4 wheel drive just adds weight and little benefit unless you are either on a slippery surface or your driving style benefits from 4 wheel drive  :wink:

Also important to remember that a 3 Door Manual ED30 is around 70 Kg lighter than a 5 door, check the stats ! This means approx' 6% better power to weight ratio. Therefore a 5 Door DSG car has a permanent 'extra passenger' weight dissadvantage, simples.

My manual 3 Door has a sunroof, so not as light as it could be, you guys with Manual ED30's 3 Door NO SUNROOF should be chuffed that you have the very best power to weight ratio of the entire GTI range ( including the 'R' with the lardass 4WD and 1521 kG which is an extra 190 Kg over a 3 Door ED30 and a power advantage of only 40 bhp :surprised: ) :happy2:

Figures are all out there if you want to be precise with referencing.

Seems a bit extreme.

Go on the ciruit and do some sessions without a passenger and then with and you will be amazed at the difference, not just speed, the biggest difference is in braking and cornering, you can carry more speed round a corner when lighter. However, on the road you won't really notice much difference (at least I hope) as you won't be driving near the edge of the envelope.

This is why the elise is so effective, in the words of the late grate colin chapman for more performance just add lightness.

Didnt ETKA prove that all the internals were exactly the same ?

....Yep, the good old 'power-to-weight-ratio' - Basic physics.

I think that Lotus have taken it too far for my taste though - I really don't like them.

yep im sure some of the tuners dissected them and found the S3/ED30/Cupra all the same

That will be 90% of british roads in british weather then  :signLOL:

Didnt Johnny C go back to the Ed30 after his S3 though? Must be better if it was worth doing that!

the s3 engine is slightly stronger, woopey fooking doo. Doesnt make em anymore powerful though when fettled  :laugh:

Well Jonny can answer for himself of course, but I'd be surprised if he said that his car choices were principally driven by whether FWD or 4WD/quattro. More likely to be tuneability, driveability and a vision for a project.
