HI Guys,

i had my S3 2010 remapped last weekend and for some reason it feels very flat in lower rev range, i still get a lag until it hits around over 3000rpm is this normal? i thought around 2-3000rpm it will have more torque so it will be quick off the mark and less lag but could be wrong. Any one else have this experience or does anyone have a dyno they could share?

I have been advised this is normal and that i have the most aggressive map loaded but i have read people describing the difference as night and day and it drove like stock when i left the garage. only when i put my foot down and really give it some, does it feel faster but that is not what i expected as i do short round town driving i expected more speed and torque at the lower end.

Any help would be appreciated.

Thanks,

K
 
If you posted your dyno plot people could see what the results of the map were. Where abouts did you have it mapped ?
 
I just got my a3 revo staged 1 and i dont get lag, kicks in hard pretty low rev range and just powers through the rest of it. Loads faster than stock and i do a fair bit of town driving too but country roads is where its at.
 
@desertstorm sorry mate i might not have been clear but i dont have a dyno of my own havent done one yet. just wanted to find out from others their experience and if someone has their own dyno plot then if they could share it.
 
I never found this issue with mine on a Stg1 map.

It has to be said that the most aggressive settings will trade a bit of low down response for mid to upper range.
The K04 should hit its boost a lot lower than 3500rpm.....the GTX3582 that I use,which is huge by comparison is on boost at 4000 rpm.
 
Thanks guys, maybe its me then expecting too much torque at lower range but it is definitely quick after around 3000rpm when it hits boost. hopefully someone can post a stage 1 dyno so that i can see if my real world experience is similar to what the dyno shows. i was expecting that when im in 2nd and going fairly slow then i put my foot down the car would move off quicker but i can have my foot all the way down and still have to wait 1-2 secs before the car realises my foot is down.
 
My experience of it was that low end torque was improved,and off boost performance wasn't affected.

The best I can do is show you an old Stg2+ map results....

WIth this,if anything you'd expect the low end results to be worse,but as you can see,the K04 is well onto the boost at 3000rpm

Did they do a health check on it before they mapped it? Most likely the issue is the DV is split / leaking, but not easy to diagnose on a forum.
 
People describe stage 1 maps a little over the top ive found. Mines a shark stage 1, I wasnt that amazed after the map. I had these power graphs done independently before and after the map so no disputing its effects I just think that the HP increase isnt going to give you a night/day improvement. Going straight to stage 2+ I imagine is a huge difference!

271hp standard
309hp mapped

You shouldn't expect a huge lump of torque in low revs from a 2.0L turbo, you're just not going to get it. Turbo lag, enough said really, drive on and be happy. Higher up the revs in a small engine turbo car is where the fun is at :)
 
Below is my Revo stage 1 map on the S3. Boost starts to kick in at 2800rpm, I find 3250rpm being the sweet spot for full boost.
I had my boost settings at 8 at the time.
Don't expect the turbo spool up immediately if you're in the wrong gear.
Go for a drive, get in to 4th gear, then drop in to 3rd so its about 3000rpm then floor it to red line.

i got mine done from SCC i st albans a revo dealer. Thanks guys for the dyno graphs, i think i may have been expecting too much at lower range so i will try your 4th to 3rd tonight and see what i feel. Also i will take a look at the DV as that is something i thought about as well but as mine is a 2010 i though i would have the Rev D fitted. Let you know how i get on tomorrow when i get a chance to take a look

I've had a LOT of work done on my previous car at SCC, the only place I took the car for work. If you have any issues call them and talk to the owner Rob. He's always got time to discuss any issues or questions with anyone. They are a good bunch of guys and know what they're doing. It's Rob who takes the cars out for the setup run after adding the map too.
 
@OliA3 yh seem like good guys, communication before and after was really good. However when i had it done it was more like heres the car see you later, so i was expecting someone to come out with me to test drive etc but perhaps that's not the norm. But anyway he said he put it on the highest most aggressive settings and that the lack of pull in lower range is normal and that for real difference i need to go Stage 2+ which i understand .
 
My revo stage 1 with revo intake made 299 stock and 343 stage 1.
 
343bhp with a stage 1? that can't be right can it should be around 300-310 i believe?
 
I'm going back there tomorrow for stage 2 map now that I have gutted my precat on stock exhaust. Revo said that's fine to run stage 2 on
 
Yeah. Only mod car had was revo intake and dynod 299 stock. Then 343 when stage 1 was loaded on.
 
i think the dyno needs to be re-calibrated that seems way too much over even with a revo intake. but i could be wrong i am sure some of the other lads could advise if this is common?
 
The torque is right tho for standard and stage 1.
 
yeah the torque seems right from what i have read and seen so seems strange, well i would hope i could get 300lbft of torque at 3000rpm lol it doesnt feel like it right now so i think i will try and find a rolling road near me and get this done
 
Either I have a very good strong engine or dyno is way out. But it's usually really accurate with figures from other cars that have been on.

There is also a fair amount of variation over what cars produce from stock,according to the usual dyno lottery,as well as things like a CAI(as you already have) and how new/old the engine is,and what fuel you run.

Initially,completely standard(i.e. no CAI etc) mine just about made the rated 265bhp,so adding in the best of the current CAIs it's easy to see that yours should produce a bit more.
Taking that into account,mine produced 330bhp at Stg1,without a CAI,which is close enough to yours to be within the variations between dynos and different days.

My point here is that a Stg1 map should,and does produce a noticeable improvement for most people,but it will not feel like night and day,as it only amounts to about a 20% increase in real terms for most cars.

Off boost performance,or what most people interpret as lag,won't be significantly improved with a remap,and depending on how the torque delivery is mapped,may even feel a bit worse low down.

What all these maps do show is that the stock K04 is around it's peak torque by around 3000rpm in most cases,ignoring the small mid-range blip that most of the maps turn out.

Sounds like a high reading RR with 299 at standard.

Very likely,but the Revo intake will help a bit as well.

RR's are most useful for trend data when you've done another remap(if you're using the same dyno) and for setup proposes.
Other than that,they're useful for the usual shootouts and bhp contests.

It's going there tomorrow for stage 2 map so see what it does with that.

You'll certainly notice a difference,but it gets into the law of diminishing returns,at least in value terms!

I still think that Stg2+ or a hybrid offer the best value bang-for-buck overall.
 
Yea definitely, ultimately a dyno's final figure is only comparable to itself really. 299-343 shows the maps given its desired effects.

Not expecting a massive difference in how it drives stage 2 but will see

The big difference on the stock turbo is when you add all the parts together...HPFP/CAI/exhaust.
Stg2+ or whatever various tuners call it gets the maximum from the K04,and the relative loss of midrange torque where the stock HPFP runs short of flow is of course improved.

I definitely noticed the difference between Stg2 and 2+,but at least with this engine,all the parts you need for one step are still required for the next.
 
I had my stage 2 revo map loaded on Saturday and with a revo intake and precat delete it ran 352bhp

wow...that's probably more than my car does on stage2+.
on a stage 2 it did 320hp and 450 Nm...
 
Before was 299 stock with revo intake, then 343 revo stage 1. Then went back for stage 2 and made 352

Dyno lottery.
I think they're most useful for trend data before and after a remap,and for setting up.

Mine scraped it's way to the average figures for each stage,and only really started delivering very good figures when into the bigger turbos.
