Livernois has made it abundantly clear that this device does not improve WOT acceleration or quarter mile times. All it does is open the throttle butterfly further with less movement of the accelerator pedal. This sort of thing will make the car feel more responsive with less throttle input. No one should think that this device is a substitute for a performance tune.
Come on bruce! I know you're been in the play field longer than I...and dwell on many other forums. But I feel you are missing the method and way this device does improve performance, just not in your typical power gains or weight/temp reduction sense. I already know what other forums are saying, I lurk them all, but only speak here because to be frank, I grew tired of that sheep mentality displayed on a lot of them. Instead of jumping to negative conclusions its better to ask questions, which is what I did in a phone call to Livernois. Back when I first tried launching the 3.0T MKZ, I was terrible at it, hence my near 14 second quarter mile times. Of course only 3 runs and first time at the track added only
But I was screwing up the throttle inputs. Now I am a lot more connected to the car. If anything I'm excited how this device will make it easier for me to nail that throttle sweet spot my car calls for that perfect launch.
I hardly expect any MKZ or 3.0T owners crave more power and performance from a tune, but maybe like some better and sporty throttle control and input. So I'll be this forum's resident performance pusher just to give MKZers a thought and read. Lurkers as well. The reason Livernois said that is because they know, most of these guys are just hoping for easy power gains and output. This device will not do that, but it can help in the driver's skill area if one is aiming to improve that too, for faster quarter mile times.
In my experience: It becomes easier to "launch" by being able to increase the throttle/spool sensitivity. Everyone will have different rates they prefer. Something like this may help one find that "sweet spot" for launching from a stop without putting too much foot pressure. The device is therefore a customization aid unit in throttling control (and boosting because they work together). Someone may get better times because they find a easier throttle point that suits them well, and ultimately help achieve a better WOT/Acceleration/Quarter mile/etc. There are three basic vehicle time achievements: Vehicle Performance (A Tune, Weight, Power, Bolt on upgrades, etc.), Driver Input Skill (Brake launching and throttle control, which is where this device goes), then Location and Atmosphere (DA, Temperatures and other uncontrolled variables). I am just summing them up in three categories.
Doing a WOT stomp is never effective compared to a skillfully "rolling into WOT" timing when brake launching these modern vehicles, because of all the technology and parameters in place. The ECU puts a big naggy limit if done too long or so. So instead of trying to find that throttle sweet spot guessing where and how far the pedal needs to go, and how long, this device helps you control the sweet spot point instead via setting the floor and ceiling. I find it much easier to locate and hit than in stock form, even with a Livernois tune (my Fusion at least).
There is advantage in being able to control that threshold and, can help one's personal quarter mile time improve. For all we know, there may be some throttle launch times inaccessible without adjusting the throttle's sensitivity thanks to this device. That is what I aim to play with once I get my Z back and can hit the track. I like this device gives me more customization to play at for when I go.
Clearly Livernois would have not made this if they felt it would completely obsolete their tune. Livernois also wouldn't have made it if its pointless to have because one is tuned. It only makes sense the two work together which is exactly what Livernois will say. But it is wrong to say it can't help improve acceleration/quarter mile times because of what throttle variables it helps controls for the Driver in question. This all being after I called Livernois, talked about the throttle enhancer (I definitely picked their brain on it), and placed my order afterwards feeling it was a good discussion. Now having it in hand, and testing on two different vehicles, I say it meets the expectation of what it intends and a handy tool for reducing the throttle skill floor and ceiling.
LOL that you installed it on the loaner.
I wonder what effect this would have on the adaptive cruise stop and go functionality. It might get a little jumpy unless you dialed it back to stock.
Hah it makes being stuck in a loaner not so bad at least for throttle fun. Unlike a tune, you can just move it around easily.
Shoot, I'm too nice to loaners as I pity them. Many probably beat on them, but I take good care on em. Did a DTC code clear and reset the adaptive learning for a nicer ride tailored to my style of driving. Gotta say the MKC with the 2.3 isn't bad for a cruiser, but that 2.3L would be better choice over a 2.0L anyday.
Ah yes, Adaptive Cruise Control. Good question there. I actually doubt it will do a thing but I can go test it later. Very certain the ACC commands engine speed and throttle control on its own (using its own drive by wire line). So this device should only work on manual pedal input, having no effect on Stop n' Go. This MKC has ACC but not the Stop n Go ability, so I may wait till getting back into my 2017 MKZ just to confirm 100%.
