Custom-Code Phase 1 - Customers Review

[DavidT]

Hi Everyone

Firstly thanks for all the interest in our thread .

Ok No Plots or data / vag-com logs until tomorrow.

But we can confirm the STD and C-C Phase1 figures.

STD = 303 ft-lb and 385 BHP

C-C Phase1 320 ft-lb and 409 bhp.

Some controversial results regarding the STD power but the percentage power increase with C-C Phase1 was as expected. With gains across the whole rev range.

The test car had 10,000mls on it and was totally standard.

More data and plots to follow

Many thanks

But the results are calculated as at flywheel from the dyno are they not, taken into account for transmission loss?

Need to know if this is whp or at flywheel.
I am guessing the later as transmission losses will be larger then that for whp for sure.

Hi

These perticular figures are @ the flywheel.

Personally i think the dyno was very tight with its numbers , however the percentage increase was pressent.

Cheers

I don't see any way they can be flywheel figures, the transmission losses just don't stack up. Can you confirm please ?

Hi

We always work with flywheel figures.

The posted dyno figures are also flywheel.

Hi guys, I dont think JAMES at custom code writes the software anyway... Lets not all get sucked in

Hi

I can assure you that I write ALL our tuning files.

Thanks anyway .

U sure big boy??? Things may have changed ???

All we can do to confirm any real increase is see if the cars are capable of running the quarter mile quicker than the present cars on a day with similar pressure and temperature readings.

You've ignored one variable. driver variability...

[SR71]

What a disappointment.

Just like everyone elses aftermarket tune then...

Not that I ever believed you'd get anywhere near 450hp just with a re-map....



I'm still waiting for my GTech Pro to show up....

Does anyone know what differences there are between the S5 4.2 and the RS4 4.2?

One spits our 350hp and the other, supposedly, 420?

But AntonRS has expereince that the S5 can put out as much as 380hp and the RS4 never puts out more than 400hp...one is up on its stock numbers and other is down on its stock numbers....

What are the differences between the two engines that are supposed to generate the extra 70hp?

[SimonC]

Is there an allowable percentage error for manufacturers claimed figures? If so, is Audi using this to manipulate the headline figures? If they are allowed a deviation of say 10% then on a 400-odd bhp engine they could be 40 bhp out and still comply.
Regarding rolling road results, they are a controversial way of measuring output because there's a lot going on between the engine and the computer that spits out the end result, especially on a 4wd car. What they can prove is an improvement, regardless of the accuracy of the actual bhp figure. Assuming the bench dyno was also under-reading (is the engine is out of the car and therefore operating in a different environment?) the only thing there is to go on is the percentage improvement. After all, bhp is just a number - if you drove an RS4 for the first time and thought it was fab, then Audi announced that it was 25bhp would you then think it was rubbish?
My biggest concern with this remap is the tweaked max rpm. Is that a good idea? Can the oil cope?

Hi Guys,

Just had a long chat with James at CC, very helpful and certainly knows what’s he’s talking about. Rather than making blind comments on the thread with no real knowledge of what they do or how they do it, why don’t you take 5 minutes to give the guys a call or drop them an email and find out the facts? I plan to go up and see them in the next week or so. At the end of the day as said above BHP is just a number if the car feels more responsive and there is a noticeable improvement happy days!! I look forward to reporting on my experience with them very soon. Good or bad I will give a fair opinion on their service and product. My gut reaction though is that I’m going to drive away with a big fat smile on face

Cut the rubbish and get to the drag strip. No need for more than 5000RPM unless your cruel. IF you crack 12.8 then its been worth while.

People can spend alot of money feeling good and think it. Chassis Dynos are only good and expect an error around +/-10%

[SR71]

SimonC,

I suggest you read http://www.rs246.com/index.php?name=PNp ... c&start=30 for the best thread to date on the subject....especially Page 3 with knowledegable comment from martinhans and AntoRS4.

You may or may not know that VARSITY got Audi to take his car back because it consistently (on multiple dynos over various months) failed to deliver anywhere near 414bhp. I believe his car was spitting out 365bhp?

However, in assessing relative performance, dynos have their uses and it is clear CUSTOM CODE's tune is doing what everybody elses is....jacking up torque and hp by ~5%.

But my suggestion is that its not doing their business any credibility by suggesting they'll have your car putting down 450bhp...most of us who have been on here for any period of time knew that this was a case of applying previous experience in tuning, to a car which is already close to operating at its limit. We've already paid Audi for the optimisation!

Thats why £55K changed hands in the first place!

Curiously I happened to notice paulmoss's experience with NOS spat out a 0-60 of 3.8 secs and a 0-100 of 9.7 secs.... (http://www.rs246.com/index.php?name=PNp ... c&start=15)

This compares with t_urbo's car (which has no NOS) which does 0-60 of 4.2 secs and a 0-100 of 9.7 secs.

This is obviously because the NOS is phased out towards ~6000rpm wasn't it?

I'd love to see the in-gear speeds of the NOS assisted car though....

Custom-Code are sponsoring this years GTI International (Custom-Code 2008 GTI International Sprint) we will be offering a special discount on the day (more details to follow) all remaps will get a free before and after 1/4 mile sprint. So for £352.50 you will receive a Custom-Code Phase 1 and 2 tickets for a before and after sprint.

In the mean time here is the RR Graph of the Audi B7 RS4 that was on the rollers at Weston Performance.

Graph seems pretty good with gains as expected really. Was this the best run and why were there so many runs?

Hi

Thanks

While we were there we decided to collect some extra data , for future reference.
