Has anyone tried the select a tune December update? I just received it last nite. In my opinion it is a must have. It's really opened my car up. Way smoother shifts and when u put it to the floor it just keeps pulling and never falls on its face in between gears. I'll definitely be needing new tires soon.

I have been running it for a couple weeks now. I think it is way better than the last update. I used to always run in eco mode due to the throttle being too sensitive and didn't care for the way the transmission acted in sport mode when rolling into the throttle. Now the throttle petal feels normal and the car holds the gear instead of shifting to 5500, which is pointless in this car.


I almost wish I could just set the redline at 5000 rpm.

Are you talking about the update that they posted about earlier this month? If so, I installed the update but was not happy. We all have different preferences but I liked the 2015 roll out and was not a fan of the new revision. I flashed back to the 2015 tune and waiting to see what others say.

Did you use the Force Full Flash option? What was it that you didn't like? We have had a few guys not use the force full flash option (recommended if you are flashing over a current TF cal and not over stock) that report some odd behavior with boost and shifting. Forcing a full flash corrects this as it ensures the entire ECM and TCM are re-programmed, instead of just the changes from one cal to the new one.

Yes, I used the force full flash option. I wasn't a fan of the smoothing out the throttle. I think my opinion of the throttle is largely based on driving habits. Both my wife and I are achieving decent city mpg's in sport mode, the only time we use stock is when I need cruise control, with the 2015 tune. If we need to give the car some pep, all we do is slightly press the throttle a little more and we launch. With this new update, it seems like more effort is needed to get the cruze into hyper speed. Which causes the butt dyno to calculate a loss of power in the early stages of the throttle. I will reflash the update soon and see if a change in driving habits produce different results.

I do enjoy your efforts to produce excellent tunes. I still have my PAL tune for when I am feeling spunky. And have thoroughly enjoyed the 2015 update. This 2016 update may take some time to grow on me. But if we end up not liking each other. I still have my other tunes which I'm totally fine with.

Hi and thanks for the post
I'm new to the Cruze, just bought it less than 2 weeks ago (2013 1.4 turbo). Would you be so kind as to explain the nuts and bolts of the Trifecta tune? IE: how is it actually done (dealership, laptop at home, ect...)and what type of connection used and maybe explain how you all "shift between tunes" in the Cruze? For us novices.
Thank you in advance

Thanks WOT tune, I followed your link and found this info about the Trifecta tune. Although I still don't get how it's actually flashed to the Cruze???

TRIFECTA: Chevrolet Cruze 1.4T - Driver Selectable Vehicle Modes II
Jan 06 2016 05:33 PM | WOT-Tuning in Articles
chevrolet cruze 1.4t dsvm


TRIFECTA: Driver Selectable Vehicle Modes, version II (DSVM II) is now available for the 2011+ Chevrolet Cruze 1.4L Turbo (LUJ--LUV)!

View this product in our Store!

2011+ Chevrolet Cruze - 1.4L Turbo
Posted Image

TRIFECTA is pleased to announce the immediate availability of an update to the TRIFECTA Advantage and TRIFECTA Elite calibration for the 2011-2015 Chevrolet Cruze and 2016+ Chevrolet Cruze Limited with the 1.4L Turbo engine. The new calibration is being designated DSVM II (driver selectable vehicle mode, Version 2) in accordance with the recent similar release for the Chevrolet Sonic with the 1.4L Turbo engine.

TRIFECTA's DSVM II, on the Chevrolet Cruze, is activated by the cruise control system arming switch. When the cruise control system is enabled, the vehicle operates in STOCK mode. When the cruise control system is disabled, the vehicle operates in SPORT mode. Vehicle modes can be switched at any time, as many times as the driver wishes. Cruise control system functionality is completely retained and unaffected by DSVM II.

In SPORT mode, the vehicle responds much more quickly to accelerator input. Automatic transmission shift patterns are optimized for maximum performance and responsiveness. During "everyday" driving manuevers, the vehicle feels very much like it did from the factory, but rolling into the pedal quickly reveals a vehicle that wants to GO. Attentive, but without being "twitchy", power delivery is linear and transmission shifts are purposeful. The vehicle produces maximum TRIFECTA power!

In STOCK mode, the vehicle behaves just like it did from the factory, under all driving conditions!

Just as was mentioned in the recent release of the Chevrolet Sonic DSVM II calibration, our calibration engineering team has been working on the 2016 Chevrolet Cruze Turbo. Just like any other large scale software project, GM typically uses a common "code base" within an ECU type, and this "code base" is generally updated every model year. After studying the 2016 Chevrolet Cruze ECU code in our engineering center, we discovered some improvements in calibration constructs that had not existed in previous model years, which we determined could be "back ported" to previous model years to offer an exceptionally improved driving experience not possible prior to the 2016 "code base".

This discovery, combined with feedback on the current DSVM calibration led to a complete "redo" of the TRIFECTA Cruze calibration. SPORT mode is all new, redesigned from the ground up.

Availability:

TRIFECTA's DSVM II for the 2011+ Chevrolet Cruze (LUJ--LUV) is available immediately and is incorporated into all new product orders. Exisiting TRIFECTA customers may request and receive the DSVM II calibration update at absolutely no charge by submitting a request at the following link (be sure to include your vehicle's VIN):

DSVM II Update Request

For those who are not current TRIFECTA customers, who are interested in our new DSVM II calibration have two options:

The TRIFECTA Advantage Calibration is meant for 100% stock vehicles. No individualizations or support for parts that do not function on factory calibration (if you have such modifications, be sure to check with us prior to placing order). No remote tuning.

Elite - $398 (plus s/h):

A tune file will be made specifically for you and available for download. Using a windows based laptop. You connect the USB side of the Ez Flash cable to your laptop and the other side to the OBD2 port on your vehicle and flash the tune file using software provided by Trifecta.

Thank You, I am looking forward to this and I appreciate your time and info. I will look up the "easy flash cable" and pick one up anticipating doing this tune to my Cruze

Would anyone recommend doing this to a vehicle that's still under warranty, and isn't paid off yet? In other words, is this something that can get me in trouble at the dealer if I need them, and is it going to shorten the life of the engine?

Here is the page to read for yourself about the actual Trifecta tune for the Cruze. This should answer your questions and concerns.
Good luck

The issue isn't "Hiding it from the dealership" with Transparency Mode as much as having a stock parts/tuned car to troubleshoot whatever you took it in for. Dealership takes steps to diagnose an issue on a completely stock car and they can't when you siting there in the bay with E85 injectors, flex sensor, K&N intake, BPV block off plate on turbo relocating it to charge lines of ZZP FMIC with eco shutter delete and full no cat exhaust. Not saying don't mod, just know there is a point where you can't simply flash stock tune and limp in. The way I am for my situation(s), If I can't go back stock in the time it takes to flash back stock tune then I don't do it.

As for life shortening, tunes got on this forum only magnify preexisting issues. For example #PIP5036: Possible Oil Consumption With Cracked Piston Or Pistons. That is an issue that is going to happen in that specific motor no mater tuned or stock. Tuned most likely helped it happen sooner before the power train coverage ended.

Thanks for the reply. I just wanted to make sure that there wasn't anything 'funky' going on from not using a FFF causing you to have a skewed view of the new update.

In response to what you said, yes, it takes more pedal pressure now. Providing you with a bit more control down low, which is the #1 reason people complained from last years update. Other than that, the peak power is the same. Just delivered a bit differently :)

Pretty much what he said ^^^

Throwing our calibration on a stock or very lightly modified vehicle is optimal as you can flash back to stock very quickly (a feature we provide as part of your purchase), and you can remove any light mods fairly quickly (intake). This way you have fun with the vehicle but can also flash it back to stock and take it in for service without worrying that you have a bunch of parts on there and have to de-mod.

Great thread. I'm actually about to spring for a Trifecta Elite for my 2012 Chevrolet Cruze ECO, but debating on whether to go for the stage 1 or stage 0. I'm just curious to how big of a difference the K&N intake makes on an otherwise stock application and if the filter is California legal. (I looked on the K&N website and it looks like it is.)
