Acceleration Times, who's up for it?
 

Ok Chaps, I finally got round to doing a couple of 0-60 runs in the car today as I was curious to see how she's holding up now there is 65000 miles gone by.

I wanted to see how she compared to the listed times on the wiki.

I did two back to back runs on a flat road, one in either direction

Conditions outside was dry with an air temp of 15 Celsius

Inside there was a full size spare in the boot, 3/4 of a tank of fuel, a bottle of Rioja and 8 bottles of Ale and my 14.5 stone lump to carry.

Details matter :D

Here's what I got below.

Interestingly the 0-100km/h is 1.1s off book speed, which is quite a bit IMO.

So

You forgot to mention the laptop too that easily add's 1s to the 0-60 times :ROFL:

Good figures though, I'd hate to see mine at the moment as I need a map for these A5 injectors that I fitted, plus I'm a bit more weight so might not put as much fuel in the tank :p

Indeed and it's a big 17 mbp so not the lightest ��

You should do it anyway then you'll have a base line to see if remap made any difference.

When I get chance I'll put the figures on here, you don't have anything to worry about with me beating your scores that's for sure :ROFL:

Not bothered by that, be interesting to see how close or far everyone is to the wiki times.

I'll give it a go at the weekend. Del, have you logged your data in to Excel to analyse and compare runs?

Best I wait for the tyres to wear further first... (to reduce the rolling circumference)

And maybe also fit a set of 17"s with low profile tyres :)

I have not got full version of VCDS so I never tested it with VCDS but with Torque on Android I was getting around the same time like you to 60mph on the PF D2 S8 which has book value 6.8s

I didn't know VCDS could do this!

I'll steer the ol' yacht towards my private airfield ASAP to see how she fairs.

I tried Matt but I'm a thicko when it comes to excel and charts. I tried to import the data from the log but it puts empty rows between data and I can't think of a way to clean it up without doing it manually.

So I gave up :(

What I would like to do is log the run alongside things like maf readings and fuel rail pressure, ignition advance, lambda values etc but I can't do it as VCDS has no label files for the s8 engine

Have you tried sending MAP files to RossTech? Apologies if you already know about that.
http://wiki.ross-tech.com/wiki/index...ol_Module_Maps

I have sent mine in a few times and even chatted by email with someone there, but it was a dead end.

I don't think there is enough d3 demand for them to invest the time these days.

If I had vas 5054 then I could probably get the info from that and write my own label files.

Was that with the gearbox in "S"? What brand and grade of fuel?

Can you repost the raw data and I'll take a look +++

Here you go Matt

Cheers +++

Quickly made a simple line graph. It's a bit jaggy as VCDS logs the speed with whole numbers.

First observation looks like gear changes at 2 and 5 seconds. +++

Nice I did notice duplicate speed data in the column, that would explain the stepped nature to the graph, and yes your correct it does indeed go for another gear and shift into third just as it approaches 60.

Yes the runs were done in s mode, Fuel is Shell V Power

I've additionally calculated average G-force per gear for the first run.

1st - 0 to 28mph in 1.97s = 0.65g
2nd - 28 to 55.9mph in 3.23s = 0.39g
3rd - 55.9 to 62.1mph in 1s = 0.28g

You Sir are far too intelligent to be designing houses, should be designing stuff for cars instead :D

Jack of all trades, master of none! But learning everyday :D

Here's the same graph with Marcins' 0-60 in 6.9s plotted, data taken from this thread:

I've got a program somewhere for plotting vcds graphs I'll try and get it up for everyone, makes it a lot easier than using exel +++

Edit: oh and if anyone knows where Audi would have all this information on a document or some sort for d3 label files I could try and ask my mate who until recently was an Audi tech and he might be able to get what we need ;)

Did a couple of runs this morning with Torque but reading is unreliable, I got readings between 6.0-7.2s to 60mph so quite a lot of variation. I did actually receive clone VCDS lead today that will work with full version of VCDS so I can do some tests with that as well but wife has gone out with the car at the moment because I have A6 in bits and I am on 'beer watch' now anyway so cannot drive. I also have over-sized tyres fitted to mine, 255/45R19 instead of 245/45R18 so the speed ECU see and pass on to VCDS is a bit wrong, but at least now my speedo reading match actual speed. In the past with stock wheels and tyres if speedo read 80mph , GPS was showing 75, now at 80 they match but VCDS show 76mph. So I guess the tests I will be doing will be 0-57mph to reflect the difference in tyre diameter.

my dirty derv effort
 

Today, best I managed was 8.0 sec 0-60. Used GPS to confirm 60 mph is true speed. Did many runs, but cannot find the other logs (I hate Windows,.. Thank God for dual booting Macs). Quarter tank of fuel, on the most level part of my airfield, spare wheel, slushbox in D, 17 stone me, 3 stone son and in the wet with A/C on:

Good stuff, it's holding up well.

Great results guys and Matty's graph looks really cool and interesting

Cheers Del. It's hardly a rocket, but it wasn't meant to be!

Look forward to the VCDS results too to see how it compares to the Torque App

log plotting software if others wish to use it ....

So did a couple of runs this morning, 1997 S8, about 40% of fuel , myself about 70kg and full size spare. Couple of things before I post times, first the car being older and without CAN sampling rates are a lot slower over KKL so accuracy is +/- 0.5s instead of +/-0.1s for Delboy. Secondly I have bigger tyres 255/45R19 instead of 245/45R18 so ECU see less speed than actual.

First order of business was to determine difference between actual speed and what ECU see. So I set GPS to km/h as the VCDS show speed in km/h in measuring blocks. Travelling at steady speed of 100km/h VCDS reading was jumping between 92.2 and 93.4km/h. So I took 100/93=1.075269 to find a mutiplier, which means that with actual speed of 60mph ECU only see 60/1.075269=55.8mph

I set the acceleration time to be measured 0-56mph, highlighted in bold below, this will be actual speed of 60mph. Here are the 2 results from 2 runs on the same piece of tarmac in opposite directions, not bad for 18 year old car with a book time of 6.8s

And here is graph of the first run with speed converted to mph and multiplied by 1.075269 to show real speed

Great results Ainars, when we were all at the meet I noticed that there wasn't much between the D2 and d3 s8's.

Just goes to show how much good value a d2 is +++

I was in front of you on the run to Portmeirion, had to ease off throttle couple of times to let you catch up as you were disappearing from my rear view mirror. :ROFL::ROFL:

Good results there Ainars +++

The graph starting to get interesting, with cars edging past each other at different points of the run

Yeah yeah, in my defence I had to behave as the missus was feeling ill :eek3:

Finally worked out how to get more than 1 run in the graph in Excel, so here are both of my runs to compare with Del's 1st run. The difference between the 2 of my runs is that on the first one not much is happening in first 0.25s, after that it is similar.

http://forum.a8parts.co.uk/attachmen...1&d=1434887134

Great graph Matty +++

The 3.7 with 150k on the clock is so close to the S8s that you will never be able to lose me and if my skills are better than yours then who know, you may be even inhaling my exhaust fumes coming out of them big 3" quads :ROFL:
:p

The ones with sense of humor will get it +++

So did a couple more runs today with 90% full tank, this does not seem to have much effect. Did 5.9-6.0s to 60mph all the time. Also did a log with rpm so I can see gear shift points. Graph below with speed and rpm

http://forum.a8parts.co.uk/attachmen...1&d=1435471410

Went to Santa Pod today, did 2 runs first 15.4343s and 92.54mph terminal speed , second 15.5027s and 92.54mph. Unfortunately they do not show 0-60 times. I was expecting around 15.0s and about 95-96 mph terminal speed judging by the VCDS logs. I blame it to the heat, first run car was showing 28.5C, second 31.5C, in reality it was probably 23C and 26C. It does get very hot and soak up a lot of heat while sitting half hour in the queue with engine running, I could feel straight away that car was not performing to it's best and felt that second run was slower than first. 6.0s 0-60 times I did testing with VCDS was in early mornings about 12C. I estimate I was doing about 6.5-6.6s to 60 today.

Wife should have some embarrassing videos on the phone with Civic beating me, will see if I can upload them later, now to some well deserved cool refreshments after baking in the heat.
