    Re: My Trifecta ECM/TCM tuning experience - 2010 CTS-4 3.6L DI Wagon

    I'd still absolutely 100% endorse the tune. Car has had zero issues, works as advertised and is a much more fun and engaging car to drive now. I put the stock tune back on it the other night because I was bored, and I immediately was reminded of the horrors of the OEM TCM programming. I've stated it before, but it's very apparent that GMs sole purpose while tuning the TCM was to get the car moving, and dump it into 6th gear as quickly as possible. Horrible....

    With the customer parameters Vince did with my TCM, the car is completely transformed.

    Vince still has your calibrations saved correct? I will be making a buy in the near future. Do realize GM's sole purpose of the 6th gear is to get to it as quickly as possible not really a "kick in the pants" calibration haha. Recently installed a catback exhaust for Cts v coupe for my 3.6 di coupe. Turned out better then expected now I just needed to tackle the slush box.

    Local muffler shop had a hell of a time from what I was told but it did fit pretty well tips lined up and put out a nice growl. Keep in mind I do have a v rear bumper to facilitate the v exhaust. When everything was said and done it didn't appear they needed to re bend any of the mandrel bent piping the kit comes with just modify piping to match up with stock.

    When you email Jerry, just tell him you want the same programming as I have, including TCM. Shouldn't be a problem...

    Wag-o-neer;
    Any noticeable change in either HP or MPG?
    Changing the TCM won't do much for MN-6 manual.....
    Does it still use regular?

    Absolutely a bump in HP. MPG? Not so much....

    I recommend piggy backing the VMax Black Iceolater with your tune. Great bang for the buck...

    Installed my base tune tonight! Wag-O-Neer, what all options did you have changed? Perhaps we should start a new thread with all available options and a description (if it's not obvious)...

    Yeah, I'm getting my tune as soon as I get my cable.

    wag-o-neer;
    I saw some datalogging you had done.
    It looks like the Knock sensor easily pulls several degrees out of the car even in stock tune.
    I assume these are full throttle runs.
    Does using premium let the ECU add more timing (or retard less)?
    Does the Trivecta tune wind up with more timing?
    I assume these are full throttle runs.
    Any idea what part throttle timimg is at cruise?

    Sorry it took so long to reply, I just returned from a 4 day bender....

    So as far as the ECM, I didn't request any particular changes be made. I just got their "canned" tune. However, for the TCM, that's where I got pretty specific on what I wanted...

    I asked for the car to hold each gear longer, shifts to be as firm as safely allowable, and rev-matched downshifting (throttle blipping) in Auto mode.

    After logging thousands of miles on it, I'm very happy. The only change I'm going to ask for, is that the 1-2 shift at WOT be softened just a hair. I feel like it's shocking the AWD system just a bit. Other than that, it's darn near perfect.

    Yeah, the knock sensor in these cars are very finicky, from what I've learned. You can see it pull timing in my logs, pre/post tune. The Trifecta tune does run more timing, without a doubt. I also posted logs after the tune, so you can see exactly how many degrees they've added, across the rev range. And yes, all logs were taken in 3rd gear, at WOT all the way to redline. I have no clue what part-throttle timing is set at....

    Just installed my Trifecta tune (2008 3.6DI). Much, much improved, and it's getting better every day as the ECU readapts. Shifts are much more firm which will take some getting used to, but gone are the grandma shifts that just made the car lagggggg. This engine was butter smooth before and now even more so just with more pull. Better acceleration from a stop, it makes smarter shifting decisions on upslopes / downslopes and it definitely took advantage of the slight mods I have. Overall it took the sluggishness out of the throttle response by improving power delivery.

    Definitely a good choice for the price.

    I also have a 2008 and have the Trifecta tune but my vehicle is not responding to the tune. May I ask what mods (air cleaner, exhaust, etc) you have to your car if yours is AWD or not? Also, did you ask for any special shift characteristics or do you have the normal Trifecta tune? I may ask for your specific tune and try it out. Thanks.
