Hi guys just had a stage 2 APR new 3.4 software remap on my S3 and it feel a lot better :) but???

Now on high revs it seems to stutter slightly? The tuners said its because I now need a fuel pump to cope with it all is this right? And it also seems to torque steer quite abit is that right also??

I had the choice between the 95ron map or the 98ron map so went for the full potential.

I'm happy with it I think but abit gutted that I now need to spend another £500 to stop the slight stutter.

Any feed back much appreciated,

Cheers
 
I had mine done about 2 weeks ago, Stage 2 98 ron but not sure what version no.
No hesitation on mine that ive noticed.
Out of curiously, what year is yours and did you get the full set of programs.
 
Where did you get this done?
 
What mods did you need for the stage 2+ dude?

Turboback exhaust and also recommended to have a cold air intake for stage 2. High pressure fuel pump and definitely the CAI for 2+

Yes they mentioned hat but no cruise yet, yes I have turbo back miltek and itg CAI, stage 2 330bhp supposedly but the hesitation will it be pump like they said????
 
I don't have a CAI and it pulls like a train with no hesitation so not sure on that one m8.
Hope you have a good strong clutch though lol
 
Aww man, will give it a week and see what happens and then go back if still the same. Just had new clutch and flywheel haha.
 
Yeah give it a while to adapt, mine has got stronger
 
Ye, fingers crossed then haha. Did you go Apr? And what gains did you get?
Lucky I'm going to Amd Essex on the 21st with everyone so will have some real figures then.
 
Yes APR, third time now. Not been on the dyno but my old S3 was stage 1, this feels a whole lot quicker.
I am hoping to get on the dyno at Awesome gti sometime.
Get the cruise done, you'll be glad you did for the extras!
 
Stage 2+ requires the upgraded High Pressure Fuel Pump and an uprated clutch and flywheel to see more potential.

Did they apply the stage2+ map knowing that it needed an upgraded fuel pump?

Yes absolutely. And regarding the "torque steer" check your tyre pressures and get a 4 wheel alignment done.
 
Tyre pressures for sure ,my rs3 was doing it all sorted now ..
 
I told them that i have exhaust and cai no pump.

Took it out tonight and its the same give it a good going in 3rd and hit around 6000rpm the car stutters and you can here the exhaust pop?

Worrying me abit really. :(
 
Rs4 pressure value ,auto tech hpfp move on to stage 2 plus :)
 
I had Apr on my last cupra r 265 tfsi
I had exactly the same issue along with a lot of other people
Google it and you'll find if you take your intake off it won't do it.
Its something to do with their calibration that the intake scaling for the mass meter needs to be perfect.

This was exactly what I was going to get at once I knew where it had been done.

Any tuner worth their salt should tell you exactly what you need BEFORE installing the software.

To install it,run the car and then say "oh yeah,you need the fuel pump" is frankly ridiculous.

They should log the car,and find out if it's leaning off before saying that,and should also know that the usual causes of hesitation/stutter/misfires on mapped cars are down to plugs,coil packs,etc,and the issue Marshy mentioned with the CAI.

Cheers for that guys,

So do you think i should go back or for the sake of all the hastle just buy a fuel pump will that cure my problem full stop?
Cheers guys
 
Did you have the stage 2 or 2+?
If 2 then it sounds as though your intake may be causing issues, if 2+ then that map should not be on your car anyway!
 
No stage 2 i had, there was a choice and options with pump or with out, yes i just read that vw forum link and it could be the filter which is pretty crap. Why pay £400 for an itg filter then another £500 for the map which requires the filter but theres problems and you need to take it off, this cant be right and should be rectified.

All i know is that they mentioned the fuel pump so i know they are going to say thats my problem. Stuck in the middle really with this.
 
Been there done that and went Revo this time.
If you unplug the airflow meter the car will drive perfect. This will prove the problems to do with your intake and not fuel.
If its ok with that unplugged then I'd contact Apr for a fix or get a refund and go elsewhere.
At the moment your in the best position for a fix or a refund.
 
Take your filter off and put the stock one back on. I don't have a cai and the car runs fine. Revo and Shark both said the intake is needed for stage 2 but APR said the map would scale accordingly.
I am probably going with a twintake in the future but not at the moment
 
Ye well i will disconect the maf sensor and see what happens, if it goes away then i know what to do if it doesnt then obv theres a problem somewhere that i need to look in to.

Also it looks like im in the process of buying a fuel pump anyway, but its standard pump with the autotech internals and rs4 pressure regulator. Only being on the safe side is there anyway to tell that it has actualy been uprated can you tell by looking at it?

Cheers for all the comments guys much appreciated :)
 
You won't be able to see from the outside if the pump has internals already fitted.
 
Aww well its abit of a gamble then Alex?

Bit of an update, i have taken it out today and i disconected the maf sensor, drove fine no management light or anything. Gave it abit of beans in 3rd and it was alot better but still had a slight stutter at around 6000rpm and on? Killed the fuel though could see the needle moving haha and the engine light was on when i got home.
So does that mean its not the CAI fault that people have had over on the vw forum?
 
Inmy opinion it's a combination of the software and the intake.
I doubt its fuel related.as.from memory Apr.only request 110 bar on the stage 2 map.
You really need to fit your standard airbox back on and try it.
When I did mine if ran standard airbox for a.few.days and it was perfect.
When fitting the intake back on it was ok for a day then it started again once it had adapted.
Mine was a twintake which I sold and ran standard airbox
 
I shouldnt have to take it off tho should i, thats the whole point of having a stage 2 map lol,

I see your stage 2+ do you have an intake on yours now? Along with pump etc?
 
I meant take it off to prove the point and if its ok then I'd ask Apr for a fix so you can run your itg or get a refund and go elsewhere.
I'm stage 2+ with my S3 and chose Revo so I could fit whatever parts I wanted without issue.
Yeah running Loba fuel pump and amd intake without any issues. Each to their own but for the fuel pump, if you can afford it go either Loba or Apr.
Loba first choice.
If the intake was on the car when it was mapped and you prove its ok without it then I'd go the refund route.
 
Yes I get what your saying,

Might have to then give it a try.

Aww nice set up, I'm just trying to sort out an auto tech internal pump at the moment guy has one for sale along with a rs4 pressure valve.
 
If the autotech pump is cheap then its worth a punt if you know its been assembled properly.
Didn't think the rs4 valve was required nowadays as it was only a fix for when maps were requesting 125 bar etc.
Tuners altered their maps to request 110 bar.
Of all the stage 2+ tuned tfsi's I know nobody has needed one.
 
Ye might aswel go for it hadn't I and then fingers crossed 2+ will solve all my problems haha.

It come with the pump so might aswel have it lol.
 
A couple of other points.....the ITG was marketed by APR when they were with VWRacing in the UK,under the VWR name.

I think your tuner has been a little economical with the way you've been treated here,and has a duty to ensure the car runs properly before handing it over to you.

As above,you don't NEED the RS4 PRV,but if you intend to go further with the car,it makes sense to fit it now.
 
Yes well it didn't got that well on the day tobehonest. First of all the laptop battery died half way through the map, and the car would not start or anything. So the map had to be taken off and then re-installed.
He took it down the road told me it was all good BUT I might need a few pump if the car can't take the extra need of the map. And as soon as I took it out my self the hesitation was there fist touch of the pedal.

I am abit annoyed and have emailed Evan from arp and he reckons that with the extra strain the map puts on the car there is now a part failing which is causing my problem! Sounds like an easy way out to me lol.
Am I entitled to go back get it take. Off and get my money back?
 
Go Apr UK website says 30 day money back guarantee.
Its up to you but first things I'd do is try it without the itg to make sure that's the issue and or see if someone can plug it.in to check for other fault codes.
Evan is a reasonable helpful guy but you'll need to either do these checks first or if you've decided your not happy with the software your entitled to a full refund.
I wouldn't be happy that the laptop went flat then it wouldn't start etc. Sounds like the dealer loading the map are not very good or knowledgeable.

As Marshy says,you're entitled to the 30 day guarantee,as per the website.

The tuner should have logged the car under load before giving it back to you,and ideally set it up on a RR.

I think Evan or APR should give the tuner a bit of a wake-up,as this sort of thing doesn't do them any favours.
