list of errors on new cupra :(

[RSTuning]

Ah ok, sorry i just assumed induction kit. My bad!

I need to check the diary but it's not too bad due to xmas etc. I know i have alot to book in though. If you have a date in mind let me know and i'll see what i can do.

We'll be about 3 hours on the dyno to fine tune the map and suit how you want the power

I am not in to this Stage 1 x Stage 2 y stuff, but I am interested to know that if you adapt the code on a MK2 Leon Cupra to suit modifications like an exhaust, intake and intercooler, how it could be classed as "Stage 2" when the limiting factor for every other tuner on the MK2 Leon Cupra is the amount of fuel that can be fed in to the engine?

could it need a larger FPR also?
i know he has recently had around 300bhp from a mk2 cupra

300bhp is attained by all tuners. Problem is that the pump cant get enough fuel in to the engine regardless of what FPR or injector size is used. The pump is the limiting factor.

So far i've not had any problems with the tfsi's in general but all have been a stage 1 setup. I know the octy vrs with a stage 2 sometimes experiences issues resolved by an uprated pump.

I Can take into account the mods you have on the car no problem but i would not expect better flow from a £200 quid filter than from the one the manufacturer spent thousands developing!

On average most filters we see have actually lost some power compared to a standard airbox with a foam panel filter.

If you need anymore info feel free to ask away

Cheers

P.s. any news on the car Wayne?

may need an uprated pump them. i'm not sure. Paul will be on soon enough to answer

Thought it was the common rail pump that was the issue. The in tank pump is not where the pressure drop is coming in IIRC.

Correct, common rail pump is the limiting factor in uprating the K04 version of the TFSI fitted to the Cupra, Audi S3 & 30 Annivarsary Golf. Most Stage 1 upgrades from any reputable company can offer the ECU flash with no detremental effect caused by the fuel pump (they just need to have a full understanding of its limitations)

 

[Pummy]

Assume that the mappers have already taken that into account when they measure the AFR when they developed the maps?

Thats so true, the majority of people will not accept that the standard paper filter will outflow replacement filters and enclosed cones. In this months edition of "redline" there was at most a 1bhp advantage over stock for replaceing a stock filter with various aftermarket ones, some lost power(not a 1.8T engine).

I'd hope so! I try not to touch any turbo petrols now without logging afr, especially when it appears the pumps are some what stressed!

f21????

 

[hundleton1]

was this problem sorted in the end?

 

[Al]

was this problem sorted in the end?

Nah its at the Stealer mate, to investigate F21

 

[Pummy]

Well he should be up at Ace Cafe next week so let's see if he has something to say about it.

 

[beezasport]

wonder where he has gone? wonder if seat have set it on fire tring to change f21 as its so complicated to get to!

 

[Al]

He is away making sure Haynes have detailed F21 on the MK2 Leon manual

 

[Pummy]

Give him a break lads. I am sure he has a valid excuse. I will make sure I give him some stick next Thursday

 

[H8T WP]

Okay, back to the topic. i think the problem was resolved by changing the fuel pressure sensor which had blown... not sure if it was remap related......

 

[Donnyboy]

Thats good its sorted. Did you have to pay or was it warranty?
