Went ahead and bought the Pedal Commander (PC) - why? I was tired of the sluggish response of the 3.8, and tired of turning Sport mode on and off. My car uses the Pedal Commander's PC71-BT model.
If I sum it up in a few words - it's "Sport mode with upshifts".
The G80 3.8 is not a fast car and it's potential is hard to obtain in Normal drive mode. In the car's native Sport mode the car drives very well - love the performance (for what it is) - but it remains in lower gears which keeps the RPMs up. For example, going 45 on a flat road - the car doesn't need to be running at 2,000 RPM - which it does in Sport mode. So, I found myself turning Sport mode on and off regularly.
Enter Pedal Commander - now I get the same "feel" as Sport mode, with higher gear upshifts when not accelerating.
I've tried many of the PC mode settings and while it has more modes than the Sprint Booster, there's no reason for it to have 27 modes - it has -4 through +4 each for City, Sport, and Sport+ modes - with a 0 in the middle, so 9 settings per mode. I tried most settings, looking for what was close to Sport mode while still getting smooth acceleration and predictable shifting.
I drive mostly in the city, so most of my "response" needs are in the 0-50 range. The City mode at the -2 setting works great for me. I get the responsiveness of the car's native Sport mode, but the advantages of full gear upshifts when the car is not accelerating. All ranges of the PC's Sport and Sport+ modes just seemed too aggressive and took away the ability to get a slow, smooth start. City -2 provides a balance between response, ease of driving, and proper shifting.
Setting it higher than "City -2" seemed to take away the granularity of the gas pedal travel and affected shift points. Sport+ was all over the place. I didn't think City mode was where I'd settle, but who cares what it's called.
Installation was simple if you can turn a socket wrench. Pop off two plastic screw covers using a screwdriver, remove the screws, plug in the device, and put it back together. Have a vacuum handy; there was a lot of dirt & crap behind the pedal! Wearing a head-mounted flashlight helps a bundle - it's dark back there.
The phone app is real nice - I've tucked away the PC's wiring so I don't see anything - the phone app is used to change all settings. It connects quickly to the Pedal Commander via Bluetooth. Using the app, I can turn the Pedal Commander on/off, or select any of the 27 modes. The setting I choose is retained between drives, and I can change settings while stopped, in Park, in gear, or even while driving.
There's an interesting write-up in Carguy75's post from 2018 in the link below, post #9. Carguy also includes great photos for when he installed his Sprint Booster. Anyway, the article explains that these boosters only shorten the range in which 100% of the throttle setting is obtained, making the car seem faster, but it really isn't. Claims it's a placebo effect. In other words, the article argues that you can obtain the same power and responsiveness with your own foot. In reality, I found this goal hard to reach. I simply cannot obtain the same responsiveness and ease of use that I can while using the Pedal Commander.
I have no doubt that the Sprint Booster can & does the same thing the Pedal Commander does. I chose Pedal Commander due to the variety of settings, use of the phone app, hiding all wires, and it was $10 less on Amazon. Is it worth it? Considering there are no other
mods available that offer better performance for under $300 - absolutely. If Genesis programmed their native Sport mode to upshift after acceleration (like my
Infiniti G37 did), would I have bought the Pedal Commander? Nope.
In Carguy's thead
here note post #9 from NSXNEXT provides a link to an article from a guy called "OutbackJoe" who both criticize these type of booster devices. He has some good points, but I still think Pedal Commander or Sprint Booster do offer advantages.
