The Porsche Carrera GT3RS (997.2) platform comes well-tuned from the factory, but the GIAC software upgrade will deliver a little more power, torque and drivability for your day on the track.

* Increased horsepower and torque gains of 8-14 hp/ 2-4 ft lbs. Wheel horsepower figures are supplied on the supplemental dyno plot. Crank gains are estimated with a 15% drivetrain loss
* Improved drivability, with consistent power and torque gains across the rev range.
* Raised rev limiter by 200 RPMs.
* Enhanced throttle response for a drive-by-cable system feel. Pump mode and race mode have different throttle sensitivities and retain sport mode.


A GIAC Handheld Switcher along with Race, Valet and Kill (anti-theft) modes are included with purchase. Pump mode has variable switching maps for 91/93/100 octane fuels. Race mode has maps that require 93 or 100 octane fuels.



Dynamometer test results from the GIAC MD-500 Mustang dyno are included here. The graph plots two runs (wheel HP and TQ) for a 2011 Porsche Carrera GT3RS (997.2) on 91-octane fuel. The green run is with GIAC programming. The blue run is the baseline run with stock ECU programming. The red run is with GIAC programming and 100 octane fuel. All runs are performed with a full GMG Racing exhaust system and factory intake system in place.

For pricing on this GIAC software including the Flashloader handheld switcher with 4 modes, please contact me via private message or contact a local GIAC dealer. This GIAC software can be installed by any GIAC authorized dealer. Customers are advised to call ahead to ensure that their local dealer is ready to flash this specific application.

Special thanks to Global Motorsports Group for supplying the test car in order for us to create this software package!

 

Good stuff guys!

 

Pretty nice gains for all motor. Great Job!

 

The gains are awesome for all-motor, and the best part is that the software INCLUDES the flashloader and 4 additional programs. All at a VERY competitive price.

Two thumbs up for GIAC on this one!

 

Hmm..
Warranty?

 

So could one of these programs be the stock program? I assume with the flash loader I can change programs from stock to any of the other 3 anytime I want and as many times as I want ?

Hmm may be a way to beat the CPO issue

 

All depends on your relationship with your dealer.


I'd have to check with GIAC to see which programs specifically are included, but yes, your assumption is correct. When you have the flashloader and additional programs installed, you're free to switch between those programs whenever and as often as you like.

 

We do not have a factory stock option available for this vehicle (short of physically flashing back to stock). All 4 programs are stored in the DME and can be switched on the fly as many times as you wish. Regarding any type of warranty issues, that is going to be a subjective matter based on your dealer. There are quite a few Porsche dealerships throughout the country that sell GIAC, though.

Another note, valet mode has a maximum throttle position of 33% and reduces peak power dramatically.

 

I'm an avid fan of tuning Porsches. Done 3 of em. I am not a fan of adjusting the rev limiter one bit. Beware of that. It shows up on the computer as over revs and it can be in the thousands and resale is somewhat of a problem. Tune away, but I wouldn't change the revs.

 

None of our Porsche software logs overrevs in the range that we raise the limiter to. This is the case with all of our naturally aspirated software, and our Turbo software. Recalibrating this is not easy, but we are able to do it without disabling the overrev logging function entirely. It is no problem at all with GIAC.

 

That's good news. Makes a big difference when you go to sell a car and the customer wants a computer pull. It kills the deal ALL the time. I won't say the brand I've had done, but they don't hide the over revs. Kudos to GIAC design.

 

From what I understand when the dealer does an engine related warranty repair they record and send the engine parameters to porsche, no choice. So if this tune alters anything and they can find it you will be on your own. The dealer has no say here, Porsche pays the bill.

So the tuners are clearly saying it can be found, it will be if there's any kind of problem. I wish this was not true but it is as I also have a tune.

 

The way that our software alters this data is not something that a normal scan tool can really see. It simply doesn't log overrev hours in the exact range that we raise the rev limiter. Any sort of real overrev or misshift will still be shown. In terms of other codes that can be read with a PIWIS, that is something that will be shown by any type of aftermarket software and something a customer will need to decide on before modifying their car in any way, shape or form. Strict dealers would be just as, if not more, likely to flag warranty over a modified exhaust versus a software flash. We have a very large network of OEM dealers that flash GIAC software in-house. So many of them are well educated on just how good our software is.

 

Have been real interested in a software flash, but still worry about an unfriendly dealer.

Would you be kind enough to PM if any friendly dealers that do flash in
house.

Much Thx

 

What is the cost of this flash?
