207 RC ECU reprogram

[bibo207RC]

Salex, I won't argue with you as you are the expert here.

I am just sharing my experience, ofcourse there's a difference in performace between hot and cold weather, but I never felt the difference to be so huge even sometimes when I am stuck in a rush hour and the intake is breathing hot air from the engine bay and when the road opens up I don't feel that much reduction in acceleration.

anyway that's my experience and I thought I would share it with you.

also I am bit worried as the upgraded IC blocks the radiator cooling path, as it can affect the cooling efficiency of the radiator specially in hot weather.

regards

It's a good idea to fit the Seat I.C

I'm afraid for the cooling of the engine.
The fan will works every time during hot weather to cool the engine!

Look, on the picture, we don't see the cooling radiator!!!
How can it works with the engine?

Did you make some engine temparature measures? Does it increase or not?

I remarque that the Mini IC is too big.

This time accelerating hard through all five gears.

Hi movistar,

Don't worry about the cooling. We have a few 207s here that have this intercooler (ibiza cupra) with no difference in engine cooling even on hot days.

Because this intercooler is designed to be located in front of the radiator.
There is space between the intercooler cell and the radiator and the cells flow a lot of air.

At full throttle, intake air temperature never goes over 30degrees C when we have 20degrees C ambient temperature. Water temperature stays the same no matter what you do with the car.

Guys, we have recently had a few more broken blowoff valves around here.

I wonder if you could help me start a relative topic in the french side of the forum, because this is something that will interest most tuned 207 and 308 1.6T.




You can read more about the whole story here

My French is really bad so I use this web translator to post on the french section : http://www.translate.google.com/

Give it a try.

Salex, Is this problem with certain production dates ? did they fix it in later production cars ?

[Sotiris Bouzikos]

bibo this problem is common to all 207,308 etc.
It is common to all 1.6T(thp)engines and have nothing to do with the product date.
In fact the VAG group has the same problem but their bovs can handle more intake pressure so thats why we find it a good solution.
VAG group cars don't have our lucky to that situation as they have to bought a special upgrade bov from forge...

[movistar69]

I've got a question:

This broken bov, is the standard PSA one or the VAG one?

Does it appear only with an upgrade Ecu or with the standard too?

I didn't really understand what I need to do with the VAG bov...

We need to fit VAG internal parts on standard PSA bov and keep the PSA black plastic part to fit it on the turbo?

So, why do we need to modify the harness?
Is it to fit the VAG bov directly on the turbo, without disassemble internal parts?

If you can help me, the topic about bov and hybrid harness is in Greek, and I don't understand!

Thanks.

[Sotiris Bouzikos]

thre are two options.
1.you ghange the inside parts with the others from VAG
2.change the bov with other from VAG
at the second option you need the harness from VAG
And at the end bov explode one way or another.
It is a problem..
If you can change it do it...

[movistar69]

Ok, so, if we change internals parts by VAG parts, it will explode at least.

So, the best way is to change by the VAG bov and doing the hybrid harness.

Thank you for your advice!

[Sotiris Bouzikos]

No
one way or another for stock bov with remapping or without.
Stock bov is on its limits anyway...
Even if you didn;t do anything on your car is a good piece of advice to change it

so the VAG DV is better than the stock DV but will also fail at the end ? and at the moment there's no perfect solution for this problem ?

Have you tried something like this : http://www.hksusa.com/products/?id=3262&rsku=6546
or this : http://www.altaperformance.com/products ... -Valve-VTA

[Sotiris Bouzikos]

vag bovs failed only at vag cars but can handle horse power of our cars.
What i mean is that with very good complete 1st stage we will take a horsepower of 240-250 max.
Audi s3 beggin from 260 and with 1st stage tuning goes to 300-320.At this level the bov of s3 have a problem.And this is a number that is too high for our cars.
About the hks bov i cannot understand from the photo how it works but i can tell you that the moment that you plug off your stock bov,you'll see a very nice message of 'depolution system faulty'
For alta i can tell you that.Away from that part.only from that.

[bibo207RC]

Salex, Sotiris, both my RC and my friend's RC are suddenly consuming too much fuel, do you have any idea what could it be ?

I guess one of the sensors is taking false readings and compensating with more fuel, knock sensor maybe ?

[Sotiris Bouzikos]

After remapping?
If that then you have to check if the remapping is ok and if it is ok you have to know that our cars are a little bit hungry if you push it too hard.
But in normal conditions are more economy than stock.
Check it and tell us again..
About knocking this is a problem that we found all the time on that cars if the remapping is wrong.
If you have that problem you have to fix it because it is not the best situation for your car...

[bibo207RC]

No I sent my ECU to France and they said it's the new ECU and cannot be remapped at that time.

My engine is not knocking but maybe the sensor thinks it is and the ECU is compensating with more fuel.

What can it be ?

[Sotiris Bouzikos]

bibo this is out of my mind.We remapped several rcs'here with no problem at all.
We make some measurements now to test how much intake pressure our cars can handle and i have to say that we are very satisfied with the results.
Here is a photo of my peak intake pressure.
Tonight i'll post a video on the move to see..

[Sotiris Bouzikos]

[Sotiris Bouzikos]

you can easily see how fast is the throttle response after remapping...

[tiranor]

It's pretty impressive how much easy it seems for the car to accelerate

Bibo, check/renew your sparkplugs and -for goodness sake- get rid of your stock blowoff valve if you have not upgraded it already.

Once the stock blowoff valve starts making noise the car looses top-end power and consumes too much fuel for no reason.
Spark plug wear has a very similar result. Without the sound of course.

If you are carefull, you might hear knocking at sudden full throttle under low revs.
Since the ECU's knock sensors do not allow knocking, it raises injection to avoid performance problems. As a result, fuel consumption increases.

no I didn't upgrade the stock BOV as VW don't sell turbo cars in my country so they don't carry the parts.

will change the spark plugs and see if it helps.

Thanks

So as far as I understand the best dump valve is the one found in the latest model AUDI S3 ? and it's internal parts is interchangeable with our dump valve ?

Do you have the part no. of the AUDI S3 dump valve ?

Thanks

[Sotiris Bouzikos]

yes you can change them easily.You just pull out the main shaft and thats it.
Here is the code

06F-145-710-G (this is the code.the others is for additional info)
1 Stuck PP27.08.2008
Lot:RA-148 LS:21062958

Is that the code for the Audi S3 one ? or the Golf GTI ?

The one for the Audi should handle more pressure and more reliable, correct ?

Thanks again

[Sotiris Bouzikos]

correct
i think this is the s3 one...

Bibo, the code for the valve is 06F145710G.

It fits the Audi S3 2.0TFSI, Seat Leon Cupra 2.0TFSI, VW Golf V 2.0 TFSI Edition 30 and lately Skoda Octavia V RS 2.0TFSI.

All tfsi engines use this, but the latest revision codes (G in our case) usually shows up in Audi.

The rest of the group VAG brands take parts after Audi - Skoda being the last to get them revised .

You can replace parts of your stock bov with the ones from VAG bov, but we recommend changing it completely.
The VAG bov has a larger coil and this helps control boost a lot better.

If you measure the bov coil's resistance, you will notice that our stock bov has 13,3 ohms, whereas VAG bov has around 15ohms.

Salex and Sotitris, I really appreciate your support.

Why is it better changing the whole thing and not just the internals ? to be honest I am not comfort cutting the original car wires so I prefer only changing the internals.
