Re-Mapping 997

I recently had my Audi A5 3.0tdi remapped by superchips. They assured me that the remapping is invisible to the dealers test equipment and the only way the dealer would find out was by driving the car and noting the extra zest. For a turbo car there is a significant difference.
Talking to the superchip guy while my Audi was rechipped I asked about the merits of remapping my 997 gen 2 C2. He said that it probably was not worth it as the difference was not that great.
So in answer to your question as long as you dont tell the OPC they wont know about your remap.

As pre Jonathan's comments - a re-map as opposed to a chip change by either AMD or Revo software use Porsche parameters and will not throw up any errors or warnings on the Porsche diagnostics done.
So the dealer cannot detect the changes unless you a) admit to them or b) they take it for a run an d notice the difference and then investigate this.
A re-map will invalidfate the UK warranty so, under UK law you are on your honour to admit having a re-map to your OPC when it comes in . Clealry then this is down to your own concience.
When I asked my favorite OPC about re-maps they confirmed this, off the record an individual suggested that they did not want to know If I ever got a re-map done, gentlemen to the core.
While a re-map does not give the power returns of a turbo for normally aspirated 997's they can dramtically improve the driveability and in gear punch.
When I had my remap done, I told the guys what I wanted was better in gear acceleration and overtaking cability rather than all top end bang - this they achieved. It felt like the sports button was always on, the throttle was far more repsonsive, the engine revved mroe freely and seemed to have more mid rev torque and power.
With the sports button on it was a bit manic and really sharp with revs rising and dying away fcar more freely and far more directly to the throttle input.
For me it made it the car I always wanted. For some it can seem a bit frivolous.
In reality your talking about a 7-8% increase in power and torque so top speed and 0-60 times arean't really going to change BUT what the car does in gear and 20mph increment timings get a good shot in the arm without ruining the character of the car. In effect its like a diet - its still you but a leaner fitter you, same for the remap its still a C2/C2s/C4/C4S but with a bit more punch and purpsoe about it.
So its not going top outrun a GT3 or Turbo but it'll give another Carerra a nasty surprise - But far more improtantly is that IT FEELS much faster so ups the enjoyment factor, which is what its all about.
So if thats what your after and they are using reputable software (eg AMD/REVO) then go for it.
If you want it to drive like a different car, buy a GRT3 or Turbo

A remap, done properly, will not normally be detected during normal servicing. However ANY remap can be detected by Porsche if they look a little deeper.
The DME flash is a simply a computer file that is copied (flashed) into an area of non-volatile memory in the DME unit. Once the DME is active, the values in the file are used to control the engine. Porsche's original DME flash files contain a 'checksum' - a mathematical value computed from the data in the original, unmodified file. To check that the file remains unchanged, a checksum can also be generated from the file in the car's DME and compared with the reference value. If the mapping or any other part of the file has been changed in any way, the checksum will not match and the dealer can be certain the file has been tampered with.
This is always the case with any remap, irrespective of the claims of tuners. If Porsche WANT to know, they will always discover a remap.
On a personal note, I'd forget about extended warranties, stop stressing, modify the car to death and just get on and enjoy it!
Hmmmm........ that's exactly what I have done as it happens!!!

Checkpoint dont do Porsche all the time, they'll do the odd one now and then.
If you want a remap, speak to Wayne Schofield....

Remapped my 993; did an excellent job. He is thorough and certainly clued up on the wider issues of enlarging the area under the power curve not just upping peak HP.
He did say though when I went that coxsters and gaymans are hard to extract much extra power from.

Many thanks for the replies.
Richard, I can imagine unmodified current cars are difficult to extract any extra from. The control systems are sophisticated enough now to allow the base maps to be more or less optimal - there's no need to leave big margins of safety any more as the systems can instantly adapt to ambient conditions and/or fuel quality.
Since I've done the mods on my car, you can tell by the way it drives that the standard maps aren't quite right for what's there any more, so I'm hoping to get back a factory-smooth torque curve as well as optimising the top end for power. There's already a very noticeable improvement in performance between 3500 and 5000 rpm and again from 6000rpm to the red line from the mods I've added and I don't see the remapping exercise producing more than single digit improvements over these. What it should do, hopefully, is make the car run really well with the mods throughout the rpm band.

Spot on - key to the re-map is not just top line BHP numbers but improved drive-ability, eliminating any flat spots in the acceleration/torque curve and giving more responsiveness through the rev range.
Peak torque on mine now pretty much runs from 3k revs to 7k revs with only fractional variation. twice the range of the unmapped peak torque curve. The guys on the rolling road also remarked that the throttle was far more responsive and the revs rose and fell far more freely than the standard car. It also eliminated a nasty drop off in power and torque between 5250 revs and 6500 revs.

Wayne is based in Rochdale Lancs, and has a website "Chipwizards".
The whole gig is done on a rolling road as it is a custom chip and the mapping is done under real load conditions.
The rolling road in a Bosch which I understand are dear and used by manufacturers. His "shed" is a work of art and has a huge airflow through it (which is particularly important for aircooled cars).
The acid test is that the car drives and feels far better afterwards.

As far as affecting Warranty is concerned, there is not the slightest chance of getting an extended warranty with a re-map.
You could hope that they don't notice but, by all accounts, they will dig deep if there is a major claim and they will find any mods.
You would be paying £1350 a year for, probably, nothing.
If they will refuse a warranty for a pain protection film being on the car (see WARRANTY thread), they sure as hell won't accept a re-map!

Judging by your other posts warranty might not be such an issue if you start fitting non OEM discs and pads.
I believe that Checkpoint were also able to give you a try before buy option whereby your car is remapped and after a short period you either cough up or the remap is cancelled.
As you have only just bought the car privately it might be worth holding back for a while to see if any problems surface, did you check the cars history with an OPC?
If the rear spoiler is not OEM that could also be a warranty issue although it looks like a GT3 spoiler to me.

The other thing to bear in mind is that during a routine service the OPC may load a revised programme themselves which would wipe out any modified flash already in place, so your £699 rechip might be lost forever
