GIAC software calibrations are now available for the 2011 Porsche 997.2 Turbo S DFI (Direct Fuel Injection). This software calibration offers a few dramatic improvements over the factory performance software upgrade.


· Improved crank horsepower and torque gains at 64 hp/94 ft lbs of torque with intercoolers and exhaust.
· Improved throttle response for a drive-by-cable system feel.
· Increased torque limits to accommodate additional hardware modifications.
· Speed limiters raised to factory redline in final drive gear.
· Stock mode and a handheld switcher are included with purchase. Additional switching modes (100 octane Race, Anti-theft, Valet) are also available for purchase.


Dynamometer test results from an MD-500 Mustang dyno are included here. The graph plots power tests (wheel HP and TQ) for a 2011 Porsche 997.2 Turbo S DFI on 93-octane fuel. The red lines denote a completely stock Porsche Turbo S with OEM software, exhaust and intercoolers. The light and dark blue lines are measured with GIAC 93 octane Turbo S software, Champion Motorsport intercoolers and Tubi Race exhaust.




This calibration includes a GIAC Flashloader Handheld Switcher and stock mode. Please contact myself or a Porsche authorized GIAC dealer to receive MSRP pricing on this software.







The above graphs I have posted show physical gains by RPM over stock. This allows all of you to see just how much power we gain across the entire power band, versus how much of a gain we see from peak power of stock tests to peak power of flashed tests. The maximum gains I have posted are above 3300 RPMs to alleviate any anomalies from the PDK transmission.

Here is a comparison between stock, flash only and flash with exhaust and intercoolers. You can see the bolt on parts yield quite a bit of power under the curve.




The GIAC flash only yields nearly 50hp and 66 ft/lbs. of torque at the wheels over stock.

Here are the same "gain over stock" graphs I posted but reworked to show what the flash does without hardware.

 

Very nice!

 

Nice work.

 

So exactly how much is it to the crank with the new upgrades 600-630 ?

 

Figures at the crank are always just a guess since nobody really knows the exact drive train loss.

This will always be up for debate, but judging by the wheel numbers above, we would say this would be 620-630 crank horsepower.

Good question, thanks!
