Hi guys,
While there have been numerous posts on GIAC Stage 1 and Stage 2, I just wish to inform people on this forum the latest software update from GIAC.

I had my car flashed 2 weeks ago by Sam over at ByDesign. Sam is an awesome guy to deal with and the latest software from GIAC is great! According to Sam and GIAC, the software I received is their latest version, which essentially combines Stage 1 and Stage 2 into one flash. A lot of updates have been written into the flash (and boy, did it take a long time to flash my car, as there were a lot of codes).

So if our GIAC sponsors can chime in on what GIAC incorporated in their latest software, I think everyone here would be very interested in reading about it.

 

Cheers my friend it was a pleasure meeting you! You're a gentleman and have an awesome car collection. A true car enthusiast!

Yes with the new software you can run Stage 2 even without any other upgrades and the car runs amazing. However as soon as a higher flowing exhaust goes on it really wakes up. One thing that is not highlighted enough is how much smoother the power delivery becomes. I have always been able to count on GIAC for the ultimate power, smooth delivery and happy customers.

 

Hey Sam I forgot, with a GIAC tune can you update the software remotely? Or it has to be done at a authorized GIAC dealer?

 

Has to be done at a GIAC dealer via OBD port. But I can bench flash it if you want to send it in and I will work with you on all of the details including Sambo deal/service! I may even be able to pass through and do it. GIAC has their own flash loader software and hardware.

 

We did some updates on our stage 2 calibrations for cold weather. When it was cold outside, the DME would power reduce in some cases. We made some changes to ensure that power would remain consistent in normal/cooler temperatures. Overall power wasn't changed compared to the previous revision, though.

 

So to confirm there is only 1 version now vs the stage 1 and 2 from before? So no need to upgrade in future?

 

There are still stage 1 and stage 2 files. A new version of stage 2 was created to make the calibration more consistent in cold weather. This update was not needed for stage 1.

 

So do I need to reflash my car again if I do decide to install an exhaust? Will the new software automatically detect this and switch to the stage 2 file?

 

You will be fine. The file you have will open up with an exhaust. I will still stand behind you if you try it and feel it's too much for your taste. I know this is your sleeper

 

So Austin, do cars with Stage 2 currently have to go get reflashed? Will there be a charge for this? We do have cold weather in Atlanta. I hate to think I spent $3500 5-6 weeks ago, only to have to reflash again at an additional charge.

 

GIAC never charges for updates and they are rare as the programs are so thoroughly tuned. I would check with your local to see if you need it.
I would be happy to help and check for you if you would like to email me your vin.

 

Hi Austin,

I am interested in flashing my car with this stage 2 tune and was wondering if you guys have a dealer here in the UAE that can do this using OBDII, without having to remove the ECU.

 

Extreme Performance UAE the dealer of GIAC you can reach them at this number 0506147393 his name Khaleefa.

 

Thanks. The thing I need to ascertain is whether he can flash my ECU using OBDII (without needing to remove the ECU to send to GIAC in the US). I am reluctant to having my ECU taken off the car. From my previous conversations with some friends, I was told that the UAE dealer cant do that and must send the ECU to the USA. Will give him a call tomorrow to confirm.

 

They're OBD2 flashed on site.
