Chipped S6 Part 2, Dyno Results
 

Over 1000 km (622 miles) have been done and today I went to Chip-Logic for the final setting up of the ECU and the Dyno run.

The results are excellent. As far as the midrange goes and the torque the results are beyond my expectation.

Maximum power @ 7000 rpm: 283 kW/385 bhp (+ 13.08%)
Maximum Torque @ 3750 rpm: 497 Nm/367 lb.ft. (+ 18.06%)

But the above does not tell the whole story.

Between 2750 rpm and 4250 rpm the power has improved from 19% to 28% compared to standard. Also the torque has increased by as much as 20% at 3500 and 4500 rpm.

Well, my butt dyno wasn't at all wrong, I felt the S6 was very strong and the dyno figures just confirmed it.

All correction parameters, altitude and drag, are identical to the parameters used for the dyno run done in September 2001 when the car was still stock standard.
The only difference was the ambient temperature which was 60°F in September, whereas today it was 86°F. (not to today's results advantage).

I am, as you can gather, delighted with the results. I am not too concerned with possible damages to the car due to additional stress for the simple reason that since we loose up to 17% of the car's power at Johannesburg's altitude, the re-mapping actually gives just a bit more power at 1750 m elevation than I would have with the S6 at sea level, so the S6 here is under not much more stress chipped than if it would be at sea level standard.

But, on Thursday I'm going with the S6 to Durban (630 km South of Johannesburg) which happens to be at sea level. It should be fun :)

Hey, now you're talkin' Andre. I was kidding when I asked you to race, right? Right? Andre? :-((

Re: Tremendous improvements, the increase above 4000 RPM is fantastic! Congrats!!!

You really are a madman Andre...that is awesome...can I do this to mine?
 

Although I am at 10 feet (~3 metres for metric guys) so the power delivery might be too much for this wimpy transmission...hmmm...well, I guess I should see if I really want more after I get it...probably at least a test drive would be warranted before doing all that...

Now what about 0-60 and 1/4 mile times??? That's all I care about ya' know! ;)

You asked me to race? I though you asked me to drive my car, or did I miss something?

If I was at sea level I am not sure I would have done this, as I feel the S6
 

once fully run-in goes very nicely indeed at sea level and does not really need additional power unless your name is Chuck5something and 1/4 mile and 0-62 is your thing!!! (Sorry Chuck! :))

As for the test drive... well catch a plane :)

If you read part one on my website, there is a company in Miami who could implement Chip-Logic's software in the USA, but I guess Miami is a bit far from San Francisco!

I WOULD like to see those times if possible. BTW, what were "uncorrected" numbers?

If you go to the URL, the first column of each section are the uncorrected figures
 

all you have to do is to convert kW to Bhp (x 1.36) and Nm to lb. ft. ( x .7375621)

Your talking (writing) funny lately, Im not sure I quite understand you.... Are you on medication ? :)

Uh-oh, I'm going to have to flame you now..............
 

Using the peak HP at 7000 RPM redline, you have a measured 242 kW vs a "corrected" 283kW for a difference of 41 kW X 1.36 = 56 HP. In other words, the dyno measured 329 HP and you "corrected" it to 385, or 17% more.

Andreeeeeee! I think you're MIXING your medications. :-)

What are you talking about? 242 kW + 17% = 283.1 kW x 1.36 = 385 bhp, what's wrong with that?
 

329 bhp + 17% = 385 bhp again what's wrong with that? 17% is the correct correction factor for our altitude.
Furthermore if this was not the case than the standard figures would also be wrong, and regarless the percentage increase would remain the same....
