bad power band

Featured Replies

Not sure what to say about those graphs. There must be an issue with the car, because the revo maps do make good figures and dont look like that.

What dyno operator was this, did he mention the boost or AFR? If you were to log your car it would be easier to help. wouldnt worry about the scaling to much that can be moved around to make it cross where ever you want, and at 5250 Bhp and torque are both about 175 so in fact are crossing each other, its just the torque and bhp scales are setup differently.

Its practically impossible to RR a car with an auto box, be that DSG or conventional and get accurate power figures. The reason being you cannot use full throttle on the RR as the car will kick down and ruin the power run.

That is completely wrong.

I don't really understand why people can't use full-throttle in a DSG-car.

It's very, very, very, very, very, very, very, very, very, very, very, VERY, VERY, VERY, VERY, VERY, VERY simple!

You just put the stick in manual-mode, shift it up to 5 and hit the throttle.

Ofc you don't push it past the kickdown, you feel it very clearly when your down there ;)!

^^^

Exactly that, you dont need to attach the accelerator to the floor for 100% throttle, therefore you have no need to activate the kickdown. If they dyno operator is doing that then he hasn't got a clue. Ive had my car on loads of dynos and no one has had issues with kickdown.

A quick google (inconclusively) suggests that if in manual, you can hold it in the "+" gate (or paddle) and it won't kick down - but I suspect that applies to DSG6? Might go and try it...

That is DSG6 only i think, although i've not tried doing it in manual mode.

looks about right to me, it is Revo isn't it :p

But as said above if the operator was any good he would be telling you what's wrong, as for the kickdown it can be done, I'm sure that at 75% throttle position is 100% open so if you keep the pedal away from the kickdown you should still be getting full throttle. Don't quote me on that though but I'm sure that's how the throttle peddle works on these as they don't have a linear throttle

Thats bang on the money. @ 3/4 throttle the car is running at 100%, rendering the final 1/4 of travel pointless

Linear throttle will be going on mine now. I let Keith @ APR drive my car at the track yesterday to prove that the throttle mapping is pump. Then i got one of the racing drivers to labour the point to him for me, because thats the first thing he said after getting out my car. "the throttle map from VAG is crap".

no is the temp around the air filter NOT the temp of the air going into the engine after being compressed so it could be high intake temps causing it

I agree, if your getting 22degrees intake air temp then i am impresed. Hurdy only managed a best of 35degrees with an intercooler AND Water methanol. Stock IC will be WAY more than that.

Stock IC is pony then my Evo was doing low 30's running 1.8 bar , but logging them on a dyno will always be misleading , how ever big the fan is it wont replicate what you see on the road

The "hold in gear to stop kickdown" doesn't work on DSG7 - just been and tried it...

He said the AFR was spot on, il check my boost pressure on my way home from work, the car had driven 30mile proir to the run so it was probably pretty hot so could this be due to heat soak?

30 mile, 100 mile or 10 mile it shouldn't cause that sort of issue.

Its to easy to speculate without the logs to actually see whats amiss. I cant see the map being the fault, maybe its just highlighted an isue that was there originally. Who loaded the map? Id like to think they set it up correctly!!

Revo glasgow, car drives perfectly fine so its a strange result

Whats worth logging?

Revo glasgow, car drives perfectly fine so its a strange result

Whats worth logging?

Intake temps for a start

Specified(Requested) and Actual Boost.

Specified(Requested) and Actual Lambda.

Specified(Requested) and Actual fuel rail pressure.

IATs

Load

Timing

That would be a good start. Be sure to select the rpm as well otherwise you cant pinpoint where in the rev band the issue rears its head.

Have you considered trying either another dyno or taking straight to REVO Glasgow and showing them the graph. They might be helpful

Send the guy the picture pf the graph and he never got back to me...which is unusal because hes usaly incrediably helpful

Il have a go at the graphing tonight if i have time

Just had a blast using torque app, intake temp maxed at 25

Noticed something strange though..... Using the revs proparly to accelerate the car was rapid but accelerating from low down in the rev range like you would do on a dyno it felt rather sluggish in 4th but fine in 3rd and 2nd

Tempted to try it was the standered intake on it incase the bmc is restrictive

  • 3 weeks later...

Didn't see you there but got mine Rolling roaded today at extreme, hopefully the img link works, and yes the car has no performance mods so I'm very happy with the results.

Got told i had to work this weekend, always happens when i have something planned

I think their rollers are usaly on the generous side but a good result none the less

wow, thats a good graph weeloon!

wow, thats a good graph weeloon!

Cheers, it's a good steady one at least :)

Only ever had V-Power in it since PDI

I was under the impression that when "S" mode is selected the car only shifts as high as 5th gear and revs to the limiter, been most of the way there but never got it to change up to 6th or 7th.

Most vRS DSG's go to 'S6' , at the correct speed and REVS, some can go to 'S7' ,

(they need modified to do that.)

All of them can go to 'S7' if you put them into Cruise Control, then move the Stick to 'S', that is not really 'S7',

that just displays as such.

An upchange to 'S7' on a modified vRS can happen at around 120-127 mph,

thats about the same speed as an Unmodified DSG changes to 'S6'.

Skoda give it in their brochures as

Max performance at 6,200 rpm

& Max torque (Nm/rpm) as 250, from 2,000-4,500

(that used to be shown for the 1.4 TSi as 240 Nm from 1,750 - 4,500

& max performance at 6,000 rpm)

*You are going to be producing maximum torque through 3rd, 4th & 5th most likely in 'S',

Road speed can be greater through the gears from 4th 5th 6th in 'D' Rolling road & real road are different matters .*

On the road, being in 'S' with 'Traction Control' on is not much cope when it looses traction, & the car killing your progress,

so you have to decide id 'S' or 'D' works best for you keeping traction with TC off. Can be down to tyres, surface etc.

george

Note these are in Cruise Control and really it is just 'D7' here.

You know that because the REVS are the same in S7 & D7

i was under the impression in s that it hit max speed in 5th gear, but the otherday i went out and it went into 6th then 7 in s mode and mine isn't modified... first tiem iv'e seen this also it wasn't by using the cruise control trick

max speed on a OEM vrs will be in 6th, even with 180hp you can easily get to 7k rpm in 5th.

in 6th iam not sure, iam guessing it depends wich wheels you got on, with 15`s you might can but hardly with 17/18`s.

VAG put the VW GTi & Audi A1 192bhp out with 215/40/17's

& the vRS on 205/40/17's

Like you running on 102 ron fuel on Mainland Europe, it mght be interesting to know what anyone is running for Octane when doing their Dynos/RR's in the UK. 97 ron, 98, or 99 or above.

This is the test 6 years ago, i have just now seen the Latest stuff from 5th Gear.

(no clearing of the ECU in 2012)

I've had the speedo showing 150mph in 7th, and that was in 7th from about 110mph why would you leave it in 5th or 6th?

Was that in a none modified vrs?

had mine @ 155miles in 6th, but speed went down in 7th when i was on stage 1 without an intercooler/exhaust system but on 18 inch.

now on APR stage 2 (v2.1 Testpipe file)i didnt had a chance yet but the speedo went up straight to 150 before i had to break...

the speedo diff. is alot if i compare my 17 inch winter vs my 18inch summer wheels on the autobahn.

a friend of mine had his stock vrs up to 160/162 miles on 15 inch cheap ass winter wheels

APR tuned 207bhp/ 250lb/ft

is that the quote from the APR site or a dyno fact ?

Edited by fabianoh5n1

That's odd but when I did it the temp was about 5c so temps would be nice an low.

The v2.1 file was written using my car and the figures are off their dyno.

160 on winters!! Hope they were speed rated to it lol!

Sib-rs: it was with APR stage 1

Sadly their figures are Off. Was in a dyno Last week.

Mind Sharing your dyno Data here?

Yes mate everything is in my thread about it. Search: apr content inside!

What did your car pull?
