Will I notice it more on the highway or in the city?
Most sedan drivers feel it most on the highway, where the engine holds one speed for a long time and less throttle adds up mile after mile. In stop-and-go traffic you'll notice the sharper response off the line, but fuel numbers are harder to measure there. Results vary by vehicle, route and driving style.
Does it work with cruise control?
Yes. Cruise control works exactly as before: you set your speed and the car holds it. The G44 works underneath, so the engine answers faster and needs less throttle to hold that same speed.
Regular or premium gas โ does it matter?
Keep using the fuel your owner's manual recommends. The G44 adapts to what it finds in your engine, so it works with regular, mid-grade or premium. Some drivers tell us the result changes a little depending on the fuel they fill up with.
Will it work on my hybrid sedan?
Yes, if it has a gas engine (hybrid or plug-in hybrid) and it's 2008 or newer. The G44 works with the combustion engine. It does not work on 100% electric cars.
Do you ship to my state?
Right now we ship to Florida and Tennessee. More states are coming soon.
Will it work on my vehicle?
The G44 works on gas, diesel and hybrid engines, turbocharged or not, in vehicles that use CAN communication through the OBD-II port โ in the U.S., that's 2008 and newer. It does not work on 100% electric vehicles. Some heavy trucks and farm equipment use a different 9-pin connector and need an inexpensive adapter.
Do I need an app or a mechanic?
No. There's no app, no Bluetooth and nothing to configure. You plug it into the port under the steering wheel in about a minute.
When will I notice it?
The G44 needs at least 8 starts and stops (key fully off) and around 60 miles โ usually a couple of days โ to learn how you drive. Many drivers notice a smoother, more responsive engine in the first 10 miles.
How much will I save?
It depends on your vehicle, its condition, the load and how you drive. In a documented controlled test, a loaded heavy truck used 11% less diesel on the same route. Drivers report anywhere from no measurable change in city driving to over 10% on the highway.
Can I move it to another vehicle?
Yes. It doesn't store anything and doesn't need reprogramming: unplug it from your car and plug it into your truck.
Will it turn on a warning light?
No. The G44 doesn't generate dashboard warning codes. If you ever unplug it, your vehicle works exactly as it did before.
What if it doesn't work for me?
Send it back and we refund your money. That's our money-back guarantee.
