Dump Valve

[CupraTgirl]

I have heard there is a new Dump Valve for the Ibiza Cupra T which isnt the same as most other Dump Valves. Apparentely it has two valves so that when you are simply cruising the dump valve acts as a recirulating one and when really giving it some it acts like an atmospheric one and you get the Whooshy noise.

Would anyone know if these are any good?

[Dormouse]

Not heard of thet i'm afraid.

I woul have thought that would confuse the hell out of the ECU aswell!

Dor.

[MARRA]

I've read somewhere on these threads that a company called 'impossible performance' does them but another member (side show turbo) said they don't work very well.:cheers:

[CupraTgirl]

Thats the one Impossible Performance

[CupraTgirl]

I really want to get one that makes the Whooshy noise? Is it possible?

[MARRA]

I'm a bit of a techophobe but from what I've seen on the threads the 'blow off' valve do, as Dormouse said, confuse the ECU probably giving a very jerky ride. That's about all I know, try contacting someone who's tried one. Side show turbo is the member that I've seen commenting on these. Try sending him a PM. Let us know what he says, you'll find him in the members register.:cheers:

[Shock_Xe]

I think u r on about the GFB 2 in 1 Hybrid dump Valve. Been tried and tested extensivly about 6 mths back! Myself having one. conclusions Works on standard cars but not chiped cars!!!! Turbo lag is increased ever so slightly but other wise cool, see here half way down

DV (http://www.impossible-performance.cwc.net/mk4_latest.htm)

[CupraTgirl]

Will it be ok to get then as mine isnt chipped?

[ForgeMotorsport]

Any log term usage of a dump valve or blow off valve can cause idle problems, emissions problems and cat problems, It will also be causing your acr to run rich.
If you want the best of both worlds fit agood aftermarket Diverter valve and a CAI ( induction kit ) , this way you will get the piece of mind with replacing the older Bosch valve and improved induction with a cold air intake that will give the dump valve sound.

[Dormouse]

Forge,

How often should I service my dv006? and how? simply remove the top and clean out the bore, spring and piston? add some lubrication?

Cheers

Whats so different?

What i cant understand is whats so different about the 1.8 20vt engine that gives you these problems. Ive heard of uneven idle before and that has been over come by re - adjusting the idle. Well lets put it this way my mates got a Polo G40 with a working "blow off" now surely if you can put one on a charger then why cant it go on a turbo car.

Most if not all turbo cars have ECU and they all can run a "blow off" even with high boost. My car is running 300bhp also has an ECU and idles fine no probs at all.

There must be a way!!!!

Not with the VAG ecu.

If you lose the stock filter box and replace it with an open air filter you will get the "Whooshy noise" even with a recirc.valve, especially when chipped.

[CupraTgirl]

Is the noise as good though as it would be with this new dump valve?

Also what air filter would i need to swap for the standard one?

[Jimmyboy]

I've got a Hurricane on mine, its not as loud as a whooshy dump valve but you can hear the "suck" sound in between gears. In the summer with the windows open it sounds shit hot! The best place to hear it is in the queue at Mickey D's as when you're next to a building it sounds louder! You can get Hurricane filters from Bill Brockbank (badger5 on here) for about £150 I think. Its worth looking in the accessories for sale section as people are often selling them on.

[CupraTgirl]

So its safer to get an airfilter and it chipped rather than getting this dump valve?

[Jimmyboy]

I dont know about "safer" but people seem to have problems with the dump valve where as no-one as far as I'm aware has had any with the Hurricane. :cheers:

[CupraTgirl]

Also i cant find anything about Hurricaine air filters on that website?

[ForgeMotorsport]

The chip or Forge - Revo upgrade ;) will give you the most go for your £££, a good aftermarket CAI ( induction kit ) such as Hurricane will give you increased performance and the rally - whooshing noise , and a good aftermarket diverter valve ( not dump valve or blow off valve) will give you increads turbo life and a more responsive drive :p

[CupraTgirl]

So a Hurricaine induction Kit, a chip are the things i should get for the moment

Sounds good

I cant find anything about the hurricaine kit though?

[CupraTgirl]

This is from the Badger5 website

A new and exciting product is now available to owners of Seat Ibiza & Leon Cupra 20VT's. We introduce the Dynatwist Induction kit, from Green Filters.

This Pleated Cotton Gauze constructed airfilter mounted in a spun aluminium housing, including a very important Cold Air Feed, has dyno proven 8bhp and 7lbs/ft torque improvement on our own "Chipped" Ibiza Cupra. It also adds a very nice induction growl and very subtle Dump Valve "woosh" - Badger5 Ltd is the UK distributor for this product which is available for £175 GBP + carriage.

Is this better than the Hurricaine induction kit?

I´ve replace my stock valve with a SAAB-valve (~£20), since the stock valve tend to leak after some time.
I have a JR Open Air filter (~£45) and have chipped my Leon and it makes quite a lot of "noise" att gear change :D .

Good Luck!

The hurricane has been superceded by Bill to the Green "dynatwist" (who made the hurricane i believe) its a bigger filter too.

IMO REVO, Induction and brakes are the best way to go for your car.

Funnily enough i think they are all available from Bill (ibizacupra) too.

:cheers:

PS Im not a badger salesman :D

[CupraTgirl]

I get you so they are the same air filter

I will speak to him then

[Dormouse]

PM exchanged...
Hurricane is the earlier product, now superceded by Dynatwist.
BOTH filters were Green filters, just the names changed.


Dynatwist is the larger Induction kit with higher power rating potential.

[Dormouse]

But clearly not in the same league a FI-SP Technology (TM) :D

Dor.

[CupraTgirl]

What is one of those then?

[Dormouse]

It's a bit of automotive magic that normally starts life in a varying number of sections of B&Q depending on whether you intend to fix your drains or toilets....:)

Dor.

[CupraTgirl]

What about if i got this new dynotwist air filter and the new dump valve? Would that work?

[Dormouse]

Dynotwist from Badger 5 and std recirculating dump valve would sound nice.

Dor.

[M1KETDi]

heres a members view on the dynatwist, sounds good. Im eventually going for the dynatwist with REVO.

http://www.seatcupra.net/forums/showthread.php?threadid=13268&highlight=dynatwist

[CupraTgirl]

So you dont reckon i actually need to get an atmospheric D/V then if i get this air filter?

[ForgeMotorsport]

dont fit an atmo valve it will not work properly
:)

[M1KETDi]

aviod a atmos DV at all costs. Stick with a re-circ valve ie forge DV007P, get a dynatwist induction, and you should be sorted with that.

[CupraTgirl]

Is it true that a chip will only give you 1bhp more?

[m0rk]

depends - if it's got the same program on it as std or not

most should see you near 200.

Mark

[Dormouse]

Is it true that a chip will only give you 1bhp more?

Who told you that then?

Dor.

[CupraTgirl]

Not going to mention names

Someone i know

I dont know if its true though

Also the Ibiza Cupra is 156bhp and the Ibiza Cupra R is 180bhp (is this at the wheels or the flywheel?)

[Dormouse]

Flywheel.

Dor.

[Saul]

As others have said, atmospheric DV's dont work on the 1.8T as its designed with a recirculating system.

www.revotechnik.com will give u circa 200-210 BHP and 230+lb.ft torque.

1bhp from a chip? Someones telling you porkies.. Probably don't want you going faster than them perhaps :P
Not true even with poor quality programmed chips..

156bhp should get 195bhp, and if lucky enough to have a good engine upwards of 200bhp is possible.

Bill

[max_torque]

Think cupraTgirl has been told about chips for normally aspirated cars - ie not turbocharged. on a turbo the main extra power is released by increasing the boost pressure. more boost = more air = more fuel burnt = more power! (hence 20 or 40 bhp increases)

on a N/A engine, air is only forced into engine by atmospheric pressure so chip can only slightly change how much fuel is added and how it is ignited. these changes can release some power. but typically its between 0 bhp and 5bhp on most modern cars.(used to be more on old cars that were not so well set up my manufacturer as standard)

[CupraTgirl]

So to get a good quality chip i need to go to the REVO place?

Is there loads of different types of chip or only one?

Which is the best?

[ibizacupra]

There are several options of upgrade to you.
REVO is the stealthiest (sp) as the ECU is not disturbed just reprogrammed. eg. Nothing for a dealer to look for. Optional Switching boxes or adjustments via their SPS3 box are also possible if you wanted these features.

Bespoke mapping for your specific car, Jabbasport do this. Drive in, they map your car on their dyno and get the best result they can, specific to your car and any mods it might have.

Other tuners upgrades available being:- AmD, Upsolute, MTM....

A whole raft of options.... and probably confusing as there are so many of them, and so many opinions about most of them.


If you wanted a Stealthy upgrade I would say go REVO, and if you wanted a map specific to your car I would say go Jabbasport.

(I would point out, that I am a REVO distributor, but equally have great relations with Jabbasport. Both being excellent products)

Bill

[CupraTgirl]

I dont really know much about this side of things so need as much advice as possible

I want better bhp and performance

How much is it all? Who fits it?

[m0rk]

more often than not jabbasport get the highest 'bhp' though at the sacrifice of torque

have a look at some Rolling road results from the RR day the other week

I could do a REVO upgrade for you, as could other REVO dealers..

Pricing for REVO is £499 for software, and optional SPS1 switchbox (for std to performance mode) is £150, and SPS3 is the fully adjustable switchbox, which allows extra performance to be dialed in, as well as the std switch mode & has a security feature/immobiliser, £250 extra. - Prices plus vat.

REVO's website is here: www.revotechnik.com

Jabbasport do their own chips at their premesis...
www.jabbasport.com is their website.

Bill

[CupraTgirl]

In your opinion which would be better to go for? SPS1 or SPS3?

Would they do a good job?

[m0rk]

that's the good thing with revo - there is not good or bad way of doing it

as it's non invasive they can't f*ck things up

no glue needed.

[Saul]

depends on what you want alex.

if u just want to change the program from standard to performance and then back again, SPS1 is fine.

If you wan the ability to adjust the performance of the car in 9(?)stages from standard to high performance, SPS3 it is

:cheers:

[CupraTgirl]

I think i need to go for the more expensive one

I mean if i am spending about £600 i might as well spend another £700 and get the full whack

[ForgeMotorsport]

come on down www.forgemotorsport.co.uk/revo :jog:

[CupraTgirl]

Another thing i would like to get clear

Is it true that chipping will nacker the engine, take loads of petrol and make it rev higher?

[M1KETDi]

REVO with SPS1= £762 INC VAT

REVO with SPS3= £879 INC VAT

not if its done properly by a specialist, ala REVO (www.revotechnik.com)

1.820VT engine is a cracker, built with the K-03 turbocharge to run circa 200bhp back in the early 90's when it was designed and built.

Many cars run this engine to great success and with various mods, from an ibiza with 200 bhp to an ibiza with 300+BHP (albeit with an uprated turbo)

go with a professional tuning outfit who know the car, the engine and its quirks and you will be fine.

i run the REVO software in my car and its perfectly fine, i trust the guys at REVO 100% when it comes to tuning, they know their stuff.

If you have any queries or questions, get them to reassure you on 01327-301-901

[Dormouse]

Is it true that chipping will nacker the engine, take loads of petrol and make it rev higher?

Depends what magnitudes you are looking at.

1. Knackering engine

With power comes reliability issues. Having said that, I would think that the major mechnicals will be fine i.e top / bottom end etc.

The turbo won't last as long, but then again how long will it last in the first place? swings and roudabouts. Clutch is the same.

2. Loads of petrol. Yes more, but not significantly. 1-2 mpg. You worry about that and you have to question buying a sporty car in the first place!

3. Car only revs as high as you press the loud pedal.

Cheers

Hi Guys

This chipping business is really confusing.

Im hearing all this good stuff about Revo. e,g, non detectable by dealers, big power gains etc. But its alot of money for 10 mins work. Also how many times can the standard chip be re-progamed(flashed- erase one program and put in another)? Will it one day decide its had enough?

Price for revo with sps3- £879 incl vat
what you get- 10 mins manual labour and a dongle

On the other hand I'm hearing about APR tuning. Very reputable and now trading direct to dealers. With their chiping you can have cruise control, and upto 5 programs all on the same chip. All easily changed through the push of a button. It saves you having to reload and flash the chip every time you decide you want to take it to the dealer. The down side I supose is that the new indicator stalk gives the game away when you go into the dealer.

price for Apr with cruise control, high performance program, standard program and security program - £869 incl vat
what you get- 2 hours manual labour, new chip, new indicator stalk


Not having a chip myself I would be interested to hear from people with both systems. Do dealers cotton on to APR chipped cars because of the indicator stalk?, Is Revo reliably?

Cheers

Tom

Does that mean if you change the settings on average twice a day the chip will last less than 2 months.:confused:

as i understand, you dont re-flash the eproms, you are activating codes already stored within it when your REVO software is installed

someone tell me the code on their Chip (BILL) and i'll tell you the exact times

You need to forget how long it takes to program with REVO and comparing that with $$$ and compare the technologies.... One of them involves getting into your ecu, removing an IC and replacing it with the tuners one.... This has risks, albeit low with a qualified person, but the SMT components needs competent people with experience... You are after all desoldering a multipin component off a multilayer pcb.

REVO does'nt involve any hardware alterations, does not require the ECU or any other hardware to be altered. It is this brand new technology and method you are paying for and its extensive development, along with very well developed performance software code.

The software would seem to be of higher performance than the previous APR, as REVO have done more develpment than APR ever did for EU cars. One major reason for the REVO split was one of continual development to suit the customers needs, and this was something lacking from APR as I understand it. That and the key software people who left APR USA over a year ago left them with more code to do than they had skilled people to do it with. Not a long term strategy.

My question would be how long will APR continue to exist without the main guys who did their software being there, and how will they cope with keeping up with the continual releases of variant ecu codes on newer cars. - Only time will tell I guess.

Yes there are cheaper options and different ways to get more performance via chips etc... at the end of the day you pays your money and you takes your choice. at least there is choice these days.

There is no other serial programmable product like this at this time to make comparisons with.

Good luck choosing.

regards
Bill

[Dormouse]

Yes Tom,

It takes little or no effort to remap the ecu via the diagnostic port. The capacity of the ecu memoery also is small leading to the question :- How much code is actually written, stored and activated?

The problem that is often never grasped is 'developemnt costs' i.e someones got to download the std code in the first palce, become familiar with it's workings w.r.t to various bits and actuators on the engine, develop new code and in revo's case develop a way to upload it in a non-intrusive way.

it'a all a case of market quantities that pricing is done on, so whilst a computer game may cost 1/20 of what a ecu mapping costs the s/w company will seell far more copies of there (compiled) code.

Cheers

Dor.

As far as APR vs REVO go I originally had APR and recently switched to Revo (Free upgrade from APR).

1st thing you have got to remember is that the APR Europe software developers are now REVO!!

I had APR initially and really liked the chip, had cruise control as a bonus and was able to switch proggies through that which i think is easier and better than the Revo option! However.... after having the Revo program for a few days i have noticed many advantages over APR Proggie, 1stly u still get to keep cruise control, also its totally undecteable via software methods and visual inspection which is a big bonus in my opinion! The only way you know is by driving the vehicle and comparing it with standard!

The revo program is basically an enhanced APR one. by this i mean it still keeps the stock like characteristics in the delivery but feels alot smoother but at the same time is considerably quicker on pick up (than stock and APR), especially mid range-top end due to extra boost. Also little niggles i noticed with the APR program have been removed with the REVO one. Granted that its not as easy to switch programs on the 'fly' but TBH i never switched the program back to standard mode for more than 30secs cause once i did i realised how slow the car felt and switched it straight back.

Granted that it doesnt seem value for money as other chip tuners take 2-3hrs to solder new chip onto board but you have to consider that there is no physical 'damage'/'evidence' that the ECU has been tampered with which is important due to Warranty/Insurance purposes.

From personal experience i would recomend the Revo route as opposed to the APR because of the more refined program and stealth that is the chip. If you want cruise you can still have it done at APR dealers without the chip

:cheers:

This is currently the reason that I have not taken advantage of the free upgrade from APR to Revo yet. I need this explaining.

I'm a real time embedded software engineer by trade and I've worn out a few flash chips by doing exactly that, re-writing it too much. So I am conserned by re-flashing my chip every time I want to swap programs. I mean look at it this way, even if you only change programs once a week, in two years that's 104 reprograms...

Flash chips come rated with all sorts of failure ratings, but I doubt Seat are using high flash rate chips as they would only ever assume a couple of re-writes as a maximum...

Could you clear up exactly what happens when you change programs Richard (when you get a spare minute) just to put our minds at rest?
Having seen the results at the RR day I'm tempted to change, but need to be reasured a bit first...

Cheers

Pete

[ibizacupra]

It is not reflashing the chip to change from stock to performance mode... It is just a switch (software) to tell the ecu to go find its relevent map (address) at a different location.

you won't kill the hardware as you're not reflashing.

regards
Bill

[CupraTgirl]

Wouldnt it be easier to keep the switch on all the time or does this damage it?

I mean personally i dont think i would keep it on the standard setting once i have had it done

[Jimmyboy]

CupraTgirl, the point is you would HAVE to switch it back if you took your car into a dealer otherwise they would know and may invalidate your warranty. Guess it depends on the the dealer though. :cheers:

[Saul]

If u dont think you'll ever change it, then stick with the SPS1

The switching is'nt a switch on/off.
It is done via an SPS1 or SPS3 box by having the ignition on, but not the engine running, select your setting on the SPS box(fast or slow :p 0 or 1 for example) insert into OBDII diagnostic plug, wait for beep then remove the SPS box and start car.

It is'nt a mechanical switch is'nt is'nt done on the fly. Its more a pre-selector.

Reading tamiya's comments on Revo, I understand the Revo software does not overwrite any of the factory software but uses spare space. Therefore, when you 'switch' you just read from a different part. This should last forever or longer than the rest of the car at least.

I'm not too sure how this compares to other software tuners.

[Dormouse]

you won't kill the hardware as you're not reflashing.

Heh Heh Devil Advocate Time Again.

But surely by switching programs you are re-programming the address that contains the data (pointer) to tell the ECU which address the revised look-up table is at. OK, one address is changed but it's still flashing right?

Dor tries desperately to remember the stuff he learnt in his digital electronics modules at uni :D

Cheers

Dor.

[ibizacupra]

No more than for example changing the clock settings, or say resetting fault codes for example.. You don't have a finite limit on that, and the changes are probably not disimilar.

REVO when they get round to seeing this thread will be able to confirm no doubt.

Bill
:)

[GJ18T]

Depends on where and how they would make this change.
If the flag which changes the program is stored in a piece of non-volatile memory (which is normal memory with a battery backup) like
the mileage counter or DTC's then it shouldn't be a problem.
If it is indeed stored within the flash memory then it will depend on the type of flash memory used in the ECU.

What is an interesting question (sidestepping a bit here) is what happens when the VAG dealer flashes new firmware onto the ECU as part
of a Tech Bulletin? Will the Revo software still work or will it need to be reloaded?

Cheers,
GJ.

It looks dead easy. Plug in a unit, push a button, turn key and drive (simplified version :) )

The older APR was an on-off, slide switch type of operation I think.

Yeah,

I used to have the eye spy book of EEPROMS, god forbid the next time I find a 8086-4X2-8K-3...that was a 100 pointer. Me and the Flash Memory Spotters Club all woke up with terrible hangover the next day I can tell you! :D :D

Cheers

Surely most other people though it was an on/off switch? :redface:

I want to know if i am going to be able to work it properly seeing as i dont know much technical stuff?


Don't worry about these guys making moutains out of molehills :p

Switching is easy peasy.

turn ignition on, insert your SPS box into its slot, it beeps and thats it! simple. :)

Thats from memory so how sad am I?

The Revo software is uploaded/flashed once only and then the switching or changing of settings is done via the difference in look up tables. Cannot go in to this in great detail as it may give too much away (also I am not one of our software engineers). Our competitors would love to know how this works and it looks like there is one in the midst of this thread ;)

If VAG issue a software update it will be allowed to reflash over Revo but at this point no 1.8T engine in Europe has ever had a recall for software (hell, they won't even recall coil packs so imagine the software recall costs?) If this does happen in the future we will allow any Revo dealer to re-install the software FOC.

btw, we do happen to have one Test ECU that has been reflashed over 70 times and is still going strong.
Some BMW EEPROMS apparently have a limited flash life. Maybe one of you with the eeprom bible can give the details of the devices mentioned at the top?

Was this not about dump valves:confused:


My wife said she will log on later to answer the how sad am I question.

Anyway, to get back on topic: As said earlier, don't use a dump valve as it will upset the ECU and most likely kick your car into limb mode (=safe mode with no turbo). However, if you do get your car chipped then it is wise to replace the stock diverter valve as it is most likely to start to leak as it is designed for lower pressure rates.
This will be noticed by you as power cutting out as the turbo won't be able to build up pressure.

Hope this clarifies it.

That would be don't use an atmospheric, non-recirculating dump valve.
Forge DV006 and 007's fit the bill nicely as they are recirculating DV's.

Bill,

that's exactly what I meant but thanks for the further explanation
towards the rest.

Cheers,
