CFI Enforcer Series - Carburetor Fuel Injection System

05/08/2026

Carb vs EFI isn’t the real debate anymore. The sweet spot is hybrid.

You keep the carb’s airflow and charge cooling, and you add the control carbs never had:

• Programmable ignition for stable idle, safer WOT timing, and better cruise
• Closed loop fueling to stop mixture drift when weather changes
• Supplemental fueling for clean transitions and consistent power
• Adaptive learning so the tune stays right day to day

You still get the carb sound, feel, and power — just without the part where the mixture moves around every time the conditions do.

That’s the CFI (hybrid) advantage.

A carburetor can be perfectly tuned… until the world around it changes.

Here are 5 situations no carburetor can predict:

• sudden temperature swings
• an altitude change
• rapid throttle transitions
• changes in barometric pressure
• fuel temperature drift

A carb can only be calibrated for the conditions you expect.
Closed‑loop correction handles the conditions you don’t expect.

This engine is running a carburetor — and the CFI Enforcer underneath it is doing the closed‑loop correction the carb can’t see.

That’s the gap the CFI Enforcer fills.

No matter how well a carburetor is designed or calibrated, it cannot be perfect for every scenario.

That’s why carburetor industry leaders John Kyle and Mike Laws teamed up on the CFI Enforcer. Both recognize that a carburetor has advantages EFI can’t match - and EFI can do things a carburetor will never be able to do.

The CFI Enforcer combines the strengths of both, giving you the authenticity and power of a carb with the correction, stability, and adaptability of EFI.

What happens when you combine a carburetor with closed loop control?

You get a unique marriage.

The carburetor still meters the majority of the fuel. The boosters still create the signal. The airflow path stays the same. The engine still feels like a carbureted engine.

But now the system sees the mixture in real time — and corrects it in real time.

Temperature swings? Corrected.
Humidity changes? Corrected.
Fuel blend shifts? Corrected.
Altitude changes? Corrected.

Closed loop doesn’t replace the carburetor. It stabilizes it.

“What EFI Actually Solves”

Most people think EFI’s biggest advantage is emissions or fuel economy.

But the real advantage is much simpler:

EFI removes the guesswork.

Cold morning? It adjusts.
Hot restart? It adjusts.
Storm front? It adjusts.
Different fuel blend? It adjusts.
Altitude change? It adjusts.

The driver doesn’t have to think about any of it.

EFI feels “effortless” not because it’s complicated — but because it’s constantly correcting for things the carburetor can’t see.

When you walk through a weekend car show, you probably admire the paint jobs, the stance, the chrome, the craftsmanship — all the usual things.

But here’s an interesting challenge:

If you look closely at the exhaust tips on different cars, you can actually tell which ones are running a carburetor and which ones are running EFI… without ever seeing the engine.

No hood open. No startup. No sound. Just the exhaust pipes.

If you were trying to figure it out, what would you look for?

EFI injectors push fuel through a tiny restriction, and that process adds heat.
Carburetors pull fuel into a low‑pressure airstream, and that pressure drop cools the mixture.
Since the CFI Enforcer still delivers the majority of the engine’s fuel through the carb boosters, the overall charge stays cooler than it would with full EFI — which helps both power and efficiency.

What improvements will you notice right away with the CFI Enforcer Series?

Faster, cleaner cold starts and warm‑ups

A smoother, more stable idle

Better part‑throttle drivability

No bogs, flat spots, or hesitation

More consistent AFR in all conditions

Reduced exhaust odor

Improved fuel mileage

Modern drivability. Classic carburetor character.

How about a quick history lesson?
If carburetors worked so well for decades, why did OEMs abandon them almost overnight and switch to EFI?

Classic‑car owners have always faced a forced choice:

Carburetor — authentic, powerful, simple, somewhat inefficient.
EFI — precise, consistent, adaptive.
The CFI Enforcer Series Classic removes that choice entirely. It’s a hybrid system that keeps your carburetor in place while adding the intelligence of modern electronics.

You keep the look, power, and character of a carburetor — and gain the drivability and consistency of EFI.

Carbureted engines run their best when the conditions match the calibration they were set up in. When the conditions move, the calibration doesn’t.

A carburetor that starts cleanly and idles perfectly on a cold morning is doing that because the mixture is rich enough to support cold air density. That same calibration will run noticeably richer once the dog days of summer heat and humidity arrive — because the carburetor cannot adjust itself to the change.

Temperature, humidity, fuel volatility, and seasonal storage all affect how an engine behaves. The carburetor stays fixed. The environment does not.

The CFI Enforcer Series was built for that reality. It provides an integrated system that adapts automatically as conditions change.

It’s not about correcting a mistake. It’s about eliminating the seasonal compromises every carbureted engine lives with.
