GIAC engine software and software switching for 991 Turbo applications is here. Just like the software for 991 Turbo S applications released a few weeks ago, GIAC software for 991 Turbo applications is an OBDII port flash and offers a great power gain over stock for both pump gas and 100 octane fuel:




Drivability is smooth at idle and part load, and has big boost at full load. Software features are similar to those for Turbo S applications including added boost, changes to fuel and timing, and higher torque limits. GIAC is the first tuner to offer 991 Turbo software as an OBDII port flash.
Software testing for this product was completed both in-house and remotely using proprietary logging equipment engineered for comprehensive DME access and data acquisition. GIAC worked diligently with GMG Racing and Champion Motorsport (CMS) to fine tune the software on their own vehicles.

 

Do you have dynos w/ the 93 octane? Did you guys use a different dyno than Champion did on the S tune, just trying to get a feel for what the final delta was between the tuned base and S, thanks.

 

subscribed..

 

very nice.. but there is some difference between tuned TT and tuned TTS from GIAC. was it the same dyno? thought that the number may equal

 

I don't think they can get 93 in Cali.
S.

 

Curious why AM exhaust and tune guys never seem to post dyno #'s in "pure stock" for a base-line... to better demonstrate their claims?

A 4th run line (pure stock) on the above graph would be invaluable to 991 TT/S owners considering these products.

 

Austin,
I see that the gains are specified for 91-octane.
Will GIAC be providing a tune for 93-octane for those of us everywhere else but California (and presumable other areas) that get 93 at the pump?
Assuming so, what are the gains for those cars with the additional 2 octane points?
S.

 

Thanks Austin for the info & all the handwork by you guys @ GIAC
94 octane gas is readily available in Alberta Canada where I live, what tune do you recommend for that?
Do you have any dealers in Northern California around the Bay area?

 

I believe that Champion has dyno tested their in-house Turbo, in addition to other acceleration data that they will be sharing at some point. Tom might have the dyno charts to share, though.

 

The Turbo S dyno was from Champion Motorsport on their in-house dynojet, on 93 octane fuel.

 

These cars are heavily torque controlled. Without a software upgrade, you will be hard pressed to sustain any power gains made with hardware changes made. What I mean by that, is that you might see an initial gain, but the ECU will gradually adapt that back out and bring the car back down to stock power. That said, OEM software baselines won't really change much with hardware additions after adaptation takes place. Where they will shine is when you're implementing software and hardware together.

 

We did 93 octane specific software with Champion Motorsport.

 

Dyno Spot Racing is in the bay area. IPB Autosport is in Sacramento.

 

Austin thanks for explaining this, but still......having a pure stock baseline would be nice.

Then measure "software" implementation.
and then measure combined "software AND hardware" implementation.

 

We have taken pure software baselines as well. They overlay with what you see there.
