Lawn Mower Carburetor Improves Mileage On Old Sedan

Before the Ford marketing department started slapping Maverick badges on pickup trucks, the name had been attached to compact cars from the 70s instead. These were cheap even by Ford standards, and were built as a desperate attempt to keep up with Japanese imports that were typically higher quality and more efficient than most American cars at the time. Some people called them the poor man’s Mustang. While Ford and the other American car companies struggled to stay relevant during the gas crisis, it turns out that they could have simply slapped a lawn mower carburetor on their old Mavericks to dramatically improve fuel efficiency.

The old Maverick used a 5 L carbureted V8 engine, which is not exactly the pinnacle of efficiency even by 1970s standards. But [ThunderHead289] figured out that with some clever modifications to the carburetor, he could squeeze out some more efficiency. By using a much smaller carburetor, specifically one from a lawn mower, and 3D printing an adapter for it, he was able to increase the fuel efficiency to over 40 mpg (which is higher than even the modern Mavericks) while still achieving a top speed of 75 mph.

While it’s not the fastest car on the block with this modification, it’s still drives well enough to get around. One thing to watch out for if you try this on your own classic car is that some engines use fuel as a sort of coolant for certain engine parts, which can result in certain problems like burned valves. And, if you don’t have a lawnmower around from which to borrow a carb, take a look at this build which 3D prints one from scratch instead.

Swapped Dash Module Gives Ford Maverick An Upgrade

February 7, 2022 by Tom Nardi 17 Comments

Ford is looking to make their new Maverick compact truck stand out, and so far, it seems to be working. Not only is it exceptionally cheap for a brand-new hybrid, truck or otherwise, but Ford actively encourages owners to modify their new ride. From standardized mounting points throughout the cabin intended for 3D printed upgrades, to an auxiliary 12 VDC line run to the bed specifically for powering user supplied hardware.

But we doubt even the most imaginative of Blue Oval engineers could have predicted that somebody would rip out the whole dash module and replace it with one from a higher-end Ford this early in the game. While many people can’t even find one of these trucks on the lot, [Tyvemattis] on the Maverick Truck Club forum has detailed his efforts to replace the relatively uninspired stock dash module of his truck with an all-digital version pulled from a 2020 Ford Escape Titanium.

Ford’s rendering of the original Maverick dash module.

Now we say “effort”, but as it turns out, the swap went off nearly without a hitch. The new digital module not only appears to be the identical size and shape as the original, but they both use the same connectors. Presumably this is because both vehicles are based on Ford’s scalable C2 platform, and likely means more components from this family of vehicles such as the Lincoln Corsair or new Bronco could be installed into the Maverick.

So what’s the downside? According to [Tyvemattis], the computer is throwing error messages as the Maverick doesn’t have a lot of the hardware that the dash is trying to communicate with. He also can’t change the vehicle’s driving mode, and the cruise control can only be enabled when the truck is stopped. But probably the most annoying issue is that the fuel gauge is off by 50%, so when the tank is full, it shows you’ve only got half a tank. At least one other user on the forum believes this could be alleviated by modifying the fuel sensor wiring, so it will be interesting to see how difficult a fix it ends up being.

We first ran across the DIY-friendly Maverick back in October of last year, and we’re encouraged to already see owners answering Ford’s challenge by tinkering with the vehicle. Here’s hoping this is the start of a new chapter in the long and storied history of car hacking.
