For guys having this issue with the engine management light flashing up under hard acceleration, i mentioned this in the VAGOC thread that a fair few guys on here have had the light flash up once or twice, and that some guys thought it might be the injectors.

Another guy has posted up saying to regap the spark plugs to 0.7mm, although he had a misfire, so maybe not related.

I will mention this to the guys at the dealership on Friday when I am there. If they replace them when they do the ECU update. If so I will ask the tech to make the gaps 0.7mm as a precaution.
 
Hmm this stuff about the plugs seems interesting think I might have a word with dealer get them to give me some plugs it there not any uprated ones that might be better for more power? Mine does splutter a bit under very hard load sometimes but plugs might sort that. It is hard to explain how good it sounds the videos don't do it justice really.

With the guy regapping the plugs did he say that sorted the problem?

Has anyone managed to find any performance plugs to fit our cars? Or does anyone know what plug code they are and I will have a look I got a price from main dealer and they said 62 quid I think for 4 oe ones?
 
Your right mardon its so twitchy and Chris I am at Santa pod next week for gti spring fest but that's it at the moment I need coillies first before any track work :) think I might leave my interior out for a bit lol I love the noise and the speed is insane :D

Mine was booked to have coilovers at the same time as the stage 2, but just been told there is a 6 week wait for them from Weitek and 2 weeks from H&R. Not happy at all I am afraid. :(
 
I've got the money burning a hole in my pocket for coillies but I'm saving it incase something goes tits up and I can't get it on warranty no one has made any uprated injectors yet can't find anything about plugs let alone injectors lol
 
I think it would need more than plugs. Surly upgraded injectors as well?

245hp+ is quite attainable from the stock engine with a properly designed exhaust system... the reason we don't do it is because it will break the clutch set-up... we will be holding off until a suitable upgrade to the DSG system is developed. ;)

IMO, Chris has the highest available performance within the safe threshold of the transmission :)

REVO have held back their stage 2 power as there was to much heat build up for the stock IC to cope.

Did you not find the same issues?

Absolutely not, air intake temps were ideal never exceeding 27degrees... even under prolonged full load. I suspect this is due to the unique design of Chris's downpipe which allows the turbo to run substantially cooler than stock.

Naturally an intercooler would be helpful but just how much power do you want :-o And how deep are your pockets :blink:
 
Yea I have been talking to some sponsors of my local club,BucksVag, and they confirm that the 1.4 Twincharge IC temps were always very good. I know i said previously that I was going to go for an IC, but I don't think it is worth it at the moment.

a 'unique' design. Your not exactly flooded with space for extravagant options. What does this entail over say a normal aftermarket exhaust? All performance downpipes with alarger bore, removal of the precat and a more efficient 2nd cat will lower the exhaust gas temps much lower than stock.

Its also great quoting what the IAT was but if you dont mention the ambient temp it means nothing. My stock cooler on the octy vRS used to allow the temp to rise around 25 degrees above ambient. Uprated coolers kept that within around 5 degrees above ambient. as well as a much quicker recovery.

It's custom made, you don't get much more unique than that ;) Perhaps Chris has a picture of where it joins the turbo and you can decide for yourself.:)

:think:The peak intake air temp is absolutely what is important as far as turbo efficiency is concerned ... over 30 degree c is a no no...regardless of the outside air temperature.

The point I was making was that the stock intercooler with the correct downpipe is good for 245hp + and the limitation is the transmission. An intercooler would help achieve similar performance at slightly lower charge pressure and if the transmission was up to the job you could extract more power and run more agressive spark advance with less risk of pre-ignition.:)
 
i hope they bring out clutch packs im still amazed at how fast mine is let alone with better clutch pack so you can get more power jeeesuss christ it will be insane. i wish they would hurry up with the clutches lol.

and with the standard intercooler being able to cope with that much power with the forge twintercooler it will be awesome hopefully revo will suprise us with a nice chunk more power as ic and everything is mandatory :) cant wait to find out :D

im interested in what makes it 'custom' or bespoke of one of a kind. When miltek, blueflame etc make their first exhaust for a car that is custom is it not? Does that mean every exhaust is custom then, or is it just a performance exhaust just like any other!

agreed on the IATs being key with regards to turbo efficiency. i know for every 1degreeC rise in IAT on the 2.0TFSI it was as near as dammit equivalent to a 1Hp loss in power, which is where your heat soak comes in.

However if above 30 degreeC is a No No, then how would go about cooling your inlet temps down when the ambient temperature is above 30degrees to begin with.

The inducted air is already heated to 30, then forced and compressed though the turbo/supercharger thus gaining more heat, it then relies on the IC to cool the charge temps back down, and theIC C relies on the outside air temp which is already at 30degrees. The best you will acheive is matching the ambient temp, unless you are using water methanol injection or intercooler sprays etc.

This is backed up by the TFSI logs i have done on my own and many other cars where the IATs were always above ambient whether on stock cooler or uprated. Second law of thermal dynamics says you cant cool anything below the temperature of the medium providing the cooling. This is why in hot climates guys get excellent results from the use of WMI as water takes so much of the heat energy out of the charge temps.

The peak intake air temp is absolutely what is important as far as turbo efficiency is concerned ... over 30 degree c is a no no...regardless of the outside air temperature.

as said in the post IAT are important but without mentioning the ambient temp its largely useless IMO. if it was minus 5degrees C outside and your intake temps after a full 1500-6500WOT power run had raised to 27degrees you have had a gain of 32degrees on the air inducted into the engine. Which is great.

However if the ambient is 25degrees, so intercooler is not going to be as efficient as in the above example, and you gained 27 degrees (likely to be more as the IC will not cool as much because its warmer) then you could be looking at an IAT all of a sudden your IAT is now @ 52degrees.

Im not on a witch hunt, I just read into things alot more than most, and am intrigued about the process of tuning the 1.4TSI.

Sy:)
 
Can I just ask where in britian you would find an ambient temperature of more than 30 though for this to be a problem.

it doesnt need to be 30degrees thats an example. EcotuneUk says that any intake air temp above 30 degrees is a no no.

I know from experience on previous cars that the IATs are quite often around the 30 degree marker especially when mapped and even higher in the summer. The gains intemp are even more prevelent the higher the stage of tune, ie stage 2 will suffer more than stage 1 and so on

If what he is ssaying is accurate it must be a nightmare in the like of germany or spain where 30-38degrees is the norm in the summer. Even in the UK we will be above 20degrees for a large amount of the summer, so could quite easily have IATs over 30degree whihc is of course a no no.
 
just noticed he has been banned from this forum now according the title below his username(unless hes written that) so i guess we will never know
