New Cupra Owner

[dj-rs]

Hi i have just bought a 2001 Seat Ibiza Cupra and i was wondering what the first mods i should do to the car are?

The guy I bought it from said it was totally standard apart from it being chipped, he doesnt have any idea which chip it is though as the previous owner had it fitted?? I have supposodley the standard chip but i have no idea what bhp the car is pushing out or indeed which chip is fitted. What should i do to find out?

At the moment i am looking at induction kit, exhaust and d/v?

I understand that you must fit a re-circ d/v to these types of engines but is there not a d/v you can fit that sounds similar to the atmospehric one i had on my zr turbo?

Thanks for help in advance

Been a few posts like this lately, looks like its cupra buying season.

Try searching mate, you can get a similar sound to an atmospheric dumpvalve, by running a recirc, and an open cone filter. Open as opposed to to enclosed ie a dynatwist.

 

[dj-rs]

ok mate so a dynatwist and what d/v forge 007?

 

[Forbez]

Argh, flaming internet!

Right mate, if you check the sponsor's and supporters section, bigboystoys are selling 007 dv's for £75 iirc, and as for filters you can go for, dynatwist, ram air, or jabbasport are the more common filter's.

The dynatwist and ram air are both available from Badger5 (see same section) but they are available from others.

Hope this helps mate

cool, any pics mate?

where bouts you from and pics would be nice

atmos doesnt work on the VAG engines, im sure it will be more reliable than the K series!

 

[dj-rs]

Sorry guys im from Birmingham, I havent yet took any pics of the car only had it on saturday.

My car didnt have a K series it had the 197bhp T series from a Tomcat but it was tuned to 230bhp.

Anyway only other thing i need to know is can i buy a spacer kit for rear wheels as i think they stick in way too much!

 

[cu51pra]

yeah off bill badger5 bout £80 but well worth it

i've got a Stratmosphere Hyperboost dump valve and it's amazing!! brilliant response! i purchased mine from Tuning Werkes in Croydon, give em a call: 0208 681 0208.

Info from another Website explaining why atmo DV's are not a good idea on 1.8 20V T VAG engines:

This was being discussed a while ago, and a few people were saying its fine to fit an atmospheric DV on a vag engine, I and others were saying its not, heres the reason

A modern engine management system, ie the Bosch Me unit fitted to 1.8T's has "adaptive" learning on the fuel, ignition and airflow side.

Because Me is a Torque based structure it's calculation of engine torque verses driver demand is critical to the driveability of the car and it's performance / durability.

When you fit a "leak" in the intake system (open circuit valve) the original calibration of the MAF sensor to manifold and cylinder filling modeling will not corespond. However due to the 20% allowance in the long term adaptive values the ECU will relearn you engine and "leak"

At idle the inlet model calculated airflow will exceed the MAF meters measured output, and depending on the state of your particular components - ie MAF ageing / contamination, throttle plate leakage, Fuel tank purge vapour concentration this may, or may not push the adaptive to it's 20% limit. If it hits the limit the ME unit will run in FMEM mode (Failure mode and effects management) causing reduced system efficiency. The Me unit will use the switching signal from the lambda sensor to return fuelling to lambda 1, storing the correction as a map agaisnt airflow. and add this correction to the fueling calc when operating at non closed loop conditions, ie WOT, fuel injector reenstatment (after overrun shut off, traction control intervention etc.) Now depending on how you drive and how sensative you are this may or may not be felt by the driver during certain manovevers. The throttle plate position will also learn the new airflow to maintain control of idle speed, but you may notice poor engine load rejection, ie turn on the aircon and the engine speed varries etc. or engine speed flares on starts or when operating PAS when parking.

However in all cases this will result in "incorrect" fueling. Now by "incorrect" i mean, not as the manufacturer intended. A post MAF leak will cause rich operation initially, but the adaptives will pull fuel out and become negative. This tends to cause a rich to lean spike on tip outs and other throttle transient. Now it is extremely diffucult for an untrained observer to spot these effects as they occur mainly on throttle transients, when the average drive may not notice. Therefore you could say "why do i care?". Well, any AFR excursion from the intended fuelling set by the manufacturer will result in non-standard engine operation. because of the adaptives this is unlikely to cause immediate engine problems, but over the course of time will change things like catalyst ageing, exhaust and turbo charger valve durability etc. Manufactures spend millions accruing miles on development fleets so hopefully the customers don't get landed with big bills as time goes on, and with most modern cars life'd at 150k miles (min design life) this is a big task.
It is unlikely that this will result in any performance loss, as at WOT the system is open loop, but you may see the result of an open circuit valve oas over fueling on gear changes etc. (a tell tail puff of black smoke is what you can see, a 1200 degC Catalyst is what you can't see, as excess fuel when injection reenstates and excess air from overrun shut off period combine in cat)

Now as you can see this is a seriously complicated subject and i haven't even mentioned the dreaded EOBD or OBDII words yet. Typically Bosch Me units have approximately 9000 calibratable parameters (constants, maps etc) and an engine calibration program will take a team of 8 calibration engineers 18 months to do the basic mapping and OBD validation. These days it's no problem to do the basic fuel and spark mapping, maybe 4 weeks on a midlimit engine on a dyno, but the diagnostics and emmisions devs takes years.

Moral or the story, before you start playing with something you don't understand, find someone who does!(And not just thinks they do!)

(for anyone thinking, "hey what makes me such an "expert" on this subject?" then i'd better mention the last 10 years i've spent as a senior calibration engineer at Cosworth and Prodrive!)

That info is actually from THIS website, and it was posted on CorsaSport yesterday, i assume you found it there.

 

[Forbez]

You can run an atmos DV on these cars!
It just doesn't seem to like them on chipped ibiza's!

 

[Craig!]

Incorrect, no 1.8T VAG engine likes an atmos, no matter what state of tune.

 

[Forbez]

Not incorrect!
You dont seem to get the engine managment issue's with unchipped motor's, like you do with chipped motors.

Also i'm sure there are golf's running the same engine's with atmos d/v's with no issues!

 

[Craig!]

You can run it on a standard engine and for months you won't have any errors, then three months down the like you get three or four. Been there, done that, friends Mk2 Golf w/ 1.8T engine did the same. Standard engine out of a Mk4 Golf, it didn't like the atmos at all!!

Same for two others I know who've run full atmos dv's on standard 1.8T engines. If you want the whoosh sound buy a three way adjustable valve, but even then your not guaranteed to get errors.

 

[Daz_gibbo]

yeah, just don't run an atmos! tuned or not.

 

[Jonzy]

wooshy is gay... nuff said really

 

[cu51pra]

Incorrect, no 1.8T VAG engine likes an atmos, no matter what state of tune.

not true the first mk4 golf gti's can take atmo's dv because they havn't got all the sensers that the ibiza engine has
