How to tell if GIAC Flash Software was installed?

[porschester]

I recently added couple modifications to my 997 c4s, including a TUBI exhaust, an X51 intake, and a GIAC flash software. The car was at "The Collection" in Miami. Upon taking back the Carrera, I could see the X51 intake, the TUBI, but I was wondering... HOW CAN I BE 100% SURE THAT THE GIAC CHIP WAS LOADED??? I paid $885, and so I would appreciate if anyone could tell me how to make sure that GIAC software has been installed on my car. When I asked Nicholas at the motorsport department he said that there is no way, and that I should just trust their word...and that I would feel the difference....yeah but it could be the other mods!!....He said that GIAC does not give any confirmation once it is installed....I did find this a little strange.....

Any expertise, knowledge on this matter or advice would be greatly appreciated....

Sincerely

Unfortunately that is the way it is with aftermarket power mod add on's. Unless you have them dyno your car first without Giac and after to see results, well then I guess its just a gamble. :huh:

But I mean when you upload a new software or even update the current one into a computer, it always lives the trace and the confirmation of the newer version....why wouldn't be any way to plug into your car and tell if the GIAC software has indeed taken place???.....

Well, you could always ask porsche to test the contents of the DME to see whether the CRC checks out. Mind you, its almost like shooting yourself in the foot, but can't see any other way apart from confirming the details with your own eyes at the shop you got the firmware from.

Thank you very much Popolou....."The Collection" which is the biggest Porsche Dealer in Miami is the one who actually did the chipping, the TUBI and X51 exhaust on my 997, so I guess I would not be shooting myself in the foot if I ask them to test the content of the DME, but Popolou, am I looking for the CRC checkout??? and anyway what is the CRC??....and would that then assure me that the GIAC software was loaded??.....its not that I dont trust them, but for paying $880 on a GIAC software I havnt witnessed installed, I just want to find a way to make sure :lightbulb:

Thanks for your feedback: :)

Well today I actually spoke with Rich, the Porsche head mechanic at "The Collection" and the one who worked on my car and uploaded the software. I asked him the question, and he said that I could call GIAC, give them my car's VIN number and they would be able to tell me that the car was flashed and uploaded with their software.

I will proceed with this suggestion and confirm....that way if this option indeed works, would allow anyone in the future to get confirmation with a simple phone call and VIN verification.....Nothing better than peace of mind when it comes to our Porsches :D

Actually i was referring to the official centres. The CRC is a check to ensure that the car's software hadn't been tampered with. Its a calculation of various factors that give a result meaning if the car does not report back the value expected, then its a sure fire way of confirming the DME had been 'adjusted' outside of manufacturers spec's. Trouble is, you'd effectively be telling porsche something that ordinarily people would want to keep hush hush about.

Best of luck.

Hi Popolou

Ah OK! I see what you mean...Thanks for the clarification. So I guess my best and safest option will be to call GIAC and give then my VIN so that they can confirm the sofware was installed, otherwise it seems that your solution may prove effective but too risky.

Again thanks for your expertise
