We're thrilled to announce the release of tuning support for the 3.6 powered 2012-2015 CTS models on our inTune and Trinity tuners.

Gains of 12 rwhp/15 ft-lbs can be seen when used with 93 octane fuel, in addition to improved throttle response, better shifting and improved overall performance.

Tunes for 91 and 93 octane are provided as well as a firm or hard shift option for the TCM.

You can adjust idle speed, shift points, rev/speed limits, WOT spark and fueling, and much more beyond the provided tunes if you desire.

Let me know if you have any questions!

(I've seen a bunch of 08-11 guys asking, and we're planning to look at them next ;))


Thanks

Didn't work. Not available yet.
What didn't work exactly?
If its a calibration we haven't seen yet it will let you read it out to send it to us, we update these applications weekly to add anything new we got from the field.

Thanks

I did send the file into Mike M. And it was a transmission issue. However even with the download he provided me it still did not recognize the TCM.
Awaiting new downloads.

Unknown TCM

Any plans on tunes for the 3.0? I already have a Trinity from a prior car and would like to be able to use it again.

I wonder if they have a tune for my "new" 2012 CTS AWD wagon...

Do our cars run better on higher octane fuel? I have heard differing opinions and just not sure. been running 87 Octane so far.

I felt a serious difference at 93 octane, but I usually run it at 91. The LY7 manual says use 89 for more performance & towing, but that's a dead giveaway that the ECU can compensate for more octane. I know the LLT sees more power on good fuel, yours should be even better as it's a Delphi ECU which is more advanced than the Bosch.
