APR Has there been a fix for delayed acceleration after shifting

[TurboYo]

MY car is doing this, I can post up a video if you'd like!!.. has there been a fix to this issue or anythingg??? please let me know this is very evident and while it may happen stock you'd think flashed performance software would mod the TB from closing bw shifts, Im shifting wot and also tried it releasing the throttle some and same exact problem, feels horrible. THIS IS DEFINITELY the throttle being cut in some way, Its not the tiny turbo building boost back up after Ive shifted with out lifting my foot off the ground. I can't post in the old thread so I started this, and yes I also own a 6spd CC PLEASE TELL ME THERES A FIX

I recently went to APR stg. 1 and although I rarely go WOT on it I had this happen the other day. ECS WOT pulls through 1st and 2nd and when I hit 3rd NOTHING. Full throttle, no response at all. I had to release pedal and re-engage to correct.

2010 6MT with ESC selected off.

Did you have this specific problem when stock?

Have you ran any boost logs to see if it is overboosting? The TB might be closing to protect your car from something.

My car has had the same symptoms. First with APR "stg 2" program and now with GIAC K04 program. I really hope tuners resolve this issue same way they did it with the FSI engines.

[tico]

Should we take the initiative to start a new thread about this topic where we provide the detailed information of our cars to see how many people are having this same problem?

I am going to search for the threads when APR announced a fix for something similar for the FSI engines and I believe REVO did the same thing.

[TurboYo]

MY car is bone stock on the chip, it might have even done it stock!! I can go and install the boost gauge from my 240 but I just dont know what to look for? Car spiking boost at the shift but past what? Either way I just would think that a performance flash would get rid of something like this, this probably makes the car loose at least a few tenths in any type of track straight or turning..

I have an issue with my car where the throttle plate doesnt open the same as my throttle position.. and its always going from 3rd to 4th. I have it matted, and the throttle plate slowly ramps from 20% to 100%, but if I let off and step on it, its fine.

This look like what's happening to you guys?:

Hey guys, I'll work with the engineering team to get to the bottom of this if it is an OEM software issue we can recalibrate. As many of you may know, our MK6 2.0 TSI 6MT race car is at the track for our race this weekent. You can catch it on Speed TV on the 17th. The car will see several hours of practice, qualifying and full races with our latest race car calibrations. These calibrations will put the engine though much harsher conditions than it ever sees on the street. Driver feedback and data from our data accusation tools will help us further pinpoint any small detail the drivers would ever want to see adjusted on the track. If something like this is spotted, we will make it better! If the changes don't affect component longevity or alter drivability negatively on the street, we'll make it better and roll it into our forth coming calibration updates. Bottom line, I'll bring this all to the engineers attention (just incase they havent seen the posts). If a change can be made, it will be made.

Awesome Arin! I really hope you guys can look into this. In our FSI GTI with APR stage 1 software the car is super fun and smooth. But on the TSI A3 the car never felt right.

[TurboYo]

so nothing right now that can be done on our own? I mean its pretty extreme in my car I don't know if its a CC thing only or what but its a total cut after the shift . Anything I can do? Also Im assuming these updates require ecu removal to reflash? at least for the 2010 CC.. there goes another 100$ in a "labor" job.

[TXBDan]

are you slamming gears w/ the throttle held down?

if so, well stop.

[Arin@APR]

From what I'm reading this is occurring on stock cars and cars chipped with software other than our own. If we find something to modify we'll make the changes and you can get a free update. If you are already chipped with APR software, the ECU does not need to be removed for flashing. It'd done though the OBDII port.

Who's making the payment on MY car? BTW it happens even when shifting like an old lady and fully releasing the throttle and getting back on it, it might not seem as bad because your basically doing what the ecu is forcing the throttle body to do when WOT shifting but it still does it non the less

Good to know no removal required for the update

i have the same problem, (posted about it in another thread) going from 3rd to 4th full throttle the car craps out total power loss for
about 2-3 seconds.
started happening to me since stage 2 apr.
also had the dealer scan it for codes, but found nothing.

APR why not try this in one of your cars? No one with a TSI 3-4th is the easiest one.. if you guys want a vid I can do it, you mainly feel this but you can also hear the engine just stop and then get back on it, and you might even see something with the rpms

[PatientlyWaiting]

I can't believe you are just bringing this to your engineers attention now. Other members of this forum and I have been screaming about this for almost a year and a half.

So I've posted multiple times in different threads. I have a 6spd 2008.5 GTI TSI. Since I chipped my car with the Apr 93 program 3 months ago I have noticed a very infrequent, but annoying issue. The problem happenes when driving the car hard, shifting quickly from 3rd to 4th or 4th to 5th at about 5500-6000 rpms. When the car engages the next gear it won't make boost, i.e. it will only boost to 3-4 psi until I take my foot off the pedal, wait a moment and re-apply the throttle.

That is from January 2009.

[TurboYo]

Hopefully it actually gets brought to there attention and they take a look. Its so simple and so obvious, I understand if it not replicable but look how many people you have here within just hours of a post talking about it.

If we haven't reproduced the issue here what do you want us to do? Would you rather I just ignore the topic and not respond at all? Didn't you post over a year ago about this hesitation being fixed when you replaced your factory fuel pump under warranty? I may be confusing a couple topics but I read so many a day it happens. Now, from what I gather this is NOT an APR issue. This is happening on bone stock cars, cars with APR tuning and cars with other tuners software. We now are racing the TSI pretty heavily so issues like this should come up given the demand we place on the engine. If they do, we'll repeat the issue, get to the bottom of it and 'fix' what we were given from the factory.

[MK6Murph]

Well put Arin! What do you guys expect APR to do, troubleshoot an issue they have not had? An issue that is not related to their software? Luckily APR is one of the few tuners that does extensive R&D at the track, so they are more likely to come across this problem in the near future and find a solution. Why arent you guys yelling at Revo or GIAC or ...I dont know VWoa to fix this problem.

Arin, do you recall you guys making a Revision on the software for the FSI cars with a similar issue? I am going to look for that information and put here.

[tico]

here is one but it looks that the only cars affected were the ones with DSG

Since you guys cant replicate it on your own is there anything I myself can do?? I can replicate it over and over and over. I understand it really might not be the APR software but most of us go to the flash for performance and this is a performance issue that definitely seems to be ECU related.. I'm not to familiar with all this VW stuff its all newer to me but can't I data log with vag-com?? If so maybe we can work something out with one of yours dealers in Miami where they can log my car. I have one literally a block from my house and another a block away from my job (non of which did my flash so I don't know if they'd be willing to help). Let me know..

If you see the original thread I posted it seems to have been mainly happening to us CC guys so it might be a possibility its something very simple they may have overlooked on their CC software as maybe they did all their testing on a DSG or 09's or just not enough testing was done because it wasn't an in house car.

Our software has a delay fix. Your latest file should have it. Additionally, our stage 1 and stage 2 files have this (you must allow for adaptation to complete).

Thank you for the offer. Unfortunately something like this is not loggable with tools such as vag-com.

[charlie.macpherson]

for the first time since i got my chip a year ago this happend to me 2 times last month seemed to only happen when it was cold out since then nothing

[TurboYo]

Well looks like GIAC knows about the prob and has a fix .. hopefully APR can come up with something soon then to satisfy there old, new and future customers

Can you explain what the delay is, or where it is coming from? What did it fix? Is it a specific hardware issue?

[ryan mills]

You CAN log this. Just look at your throttle pedal position and the throttle plate position. I had this issue in my car with APR software and with GIAC software. I could replicate this almost at will when accelerating on to the interstate. I can say though, with 2 gallons of 110 octane in the tank and the rest 93, the problem has not come back. I can't confirm if this is a coincedence or not.

I posted this a few posts above:

[NEW2B]

arin i havent seen any stock cars do this. maybe those few you mentioned dont really have the same issue and are experiencing
something similar.
it seems to me the problem is with flashed cars.

[siagolf]

could this be related/the same thing as the "drive by wire" lag we all hate??

[mdpay]

My car with APR stage 2 has this delay between shifts. ( 2009 TSI Man. trans.) It is very noticeable during WOT acceleration. I hope APR can provide a software cure.
