I got to go out in a mates S3 yesterday. Its a 1999 in good nick but standard. It felt a bit less frantic with a larger power band (probably helped by six speed box), but also slower than my 4x4 with normal Revo map when mine is in "the right " rev range. Just wondered if anyone thought I could do anything - cheap:( - to spread the power a bit more. Don't think I'll be changing to an S3 like this though -

Spread the power more?

Ditch the Revo and get a less peaky remap...lol

(my opinion of course).

Not sure that counts as a cheap option. One of the problems with remaps is how do you try them out? At least the Revo one you can try, and its such a power increase over the original that I didn't feel like saying no! Money no object I'd try some others.

Can't you get Revo stage 2?

Can't you get Revo stage 2?

Would that make an improvement on power spread or just more power in a narrow band - oh and how much is it? More than a fiver might be a problem:eek:

you also need extra hardware to go for Revo2

Spread the power more?

You mean that famous overboost hit low down? btw did you add me on facebook the other day? didn't recognise at first as you had your names in the wrong order

The standard S3, will be quicker than the 4X4 or vRS when remapped. The bigger turbo spools up harder and lasts a lot longer.

I think a decent cold air kit, will help spread the power at the top end, or alternatively, a custom manifold. To rev harder.

Aye I did, name thing was a failed attempt of humour, just confused people..lol.

The S3 was standard and did not feel quicker than my remapped 4x4 just had a wider and smoother power band.

As for Revo 2 unless I'm willing to spend

surely it didn't feel any quicker because of the wider powerband/smoother delivery

both of us in the S3 felt the same that overall there was nothing in it. I thought that 99 S3 had the same basic mechanicals as a 4x4 but then what do I know. It produces about 210bhp in stock form which this is. Best answer is to stick them next to each other and see what happens. I expect I'll be fine until the first corner! Or my mate gets a remap!

Early S3's suffered with the standard air intake pipe between turbo and MAF collapsing with the increased air flow demands of the remaped engine. I don't know if this was ever an issue on the Octavia. If it doesn't fully collapse it'll deform. Replace this with a Samco pipe from Forge (around

Just been searching for N75j stuff and a lot o people on here seem to think its a problem fitting it due to overboost causing the ECU to shut the power down. Any definitive tests been done on this?

There was loads on this on the uk-mkivs forums but I'm pretty sure that the 'J' version is fine for the 150bhp 1.8t engine as well as the 210bhp version in my S3. Might be worth some added research on that forum too. I think the limp mode issues are dependant on which remap you have and how close it is pushing the boost already to the allowable levels.

There were S3 people playing with 'H' versions that did throw cars into limp mode all the time - a small few got away with it but most couldn't use it.

It is really easy to fit other than the fact that it looks as if you put it on the wrong way round as the wiring point is presented on the opposite side and you have to pull the original wiring a little tight and then attach it to something to remove the strain. The hardest part is cutting off the OEM retaining clips from the hoses - use some tin snips and its easy. Get new clips (I used standard jubilee clips without any problems) first though as you will not be able to use the originals again!

If you have access to Vag-Com to reset the limp mode then IMHO its well worth a go at only

Get a Custom-code ph1 and a k+n or green panel filter thats what we have done to a few 210bhp s3's with very good results drives like a standard car but with more power everywhere! Fyi revo trails dont exist as such they re-program the ecu and then set the time frame with the service interval timer,so a revo demo'ed car has a revo remap on it anyway there isnt enough memory on the ecu for 2 maps,the settings are just returned to standard when the timer runs out!

I think some of the difference the OP is seeing is more to do with the very short gearing of the 4x4 rather than the power band being narrow.

Cheapest improvement is 99 ron fuel and up the timing with lemmiwinks or similar. Also consider smoothing the airbox and add a cold feed pipe if funds permit. Keep the filter as clean as possible too even if it's just a paper one as they really should be changed more often than they are.

Internally in the 512k or 1mb flash there is quite alot of empty memory. What isn't fully understood is that within this memory the operating system for the ECU is also stored so space used for the maps is alot less, also of those actually tuned for performance this is even less memory actually altered. Both the settings remain on the flash. All that changes is the operating system after the timer runs out uses the maps stored in a different location by means of a redirect. In the 512kb version there is over 40kb of free space which is about 38kb more than needed to store alternate maps, this is easier to understand when you realise control tables can vary from 64 to 320 bytes in hex.

Have you got Evie driving yet????!

Wrong.

The bigger turbo spools up harder and lasts a lot longer.

Nonsense. For road driving, the smaller turbo spools up more quickly and is more useful.

The smaller turbo remapped is running higher boost so marginally more lag than a standard one anyway. The larger turbo on the S3 will be working slightly more efficient where as the higher pressure on the mapped K03 without additional intercooling will reduce it's efficiency. The larger turbo is more efficient at higher rpms and will be able to hold boost better at higher rpms.

Only one way for a definitive answer

Wrong.

Nonsense. For road driving, the smaller turbo spools up more quickly and is more useful.

If you don't think the K04 spools up harder, and lasts longer, then your in a dream world mate. Infact, god knows why the even used a K04 turbo if the K03s seems to be better.

Yes, the K03 being the smaller turbo, does spin up quicker, but as you've been slightly hypocritical, the bigger turbo, will spool up harder and last longer.

Sorry didn't mean to start a fight just wondered if there was a cheap easy way of smoothing power delivery!
