TBI

Multi-port

Common Features

Both of our TBI and Multi-Port systems share the following common features:

EFI Conversion for Classic Engines

Carbs are great for bulk season, but not necessarily the best option for your engine. All of our EFI systems are designed to replace and surpass the capabilties of stock EFI and carburetors.

32-bit Architecture

32-bit architecture and automotive-grade chips that manages input/output signals, voltage, and RPM faster and more consistently than competitors.

Timing Control

Integrated coil driver for ignition timing control (Minimum output of 90mj with some systems up to 150mj).

Self-learn & Full Tunabiltiy

All of our systems have self-learning capabilities, as well as full manual tuning ability. Most manual tuning can be done via the handheld or dash, but we also offer a free laptop suite for many additional settings.

Accessory and CAN Compatibility

We design our systems for the long haul in terms of reliability, as well as compatibility. Almost all of our systems are cross-compatible with each other in some way, and all of our accessories are designed to work with any of our EFI systems. Some limitations may apply, so it's always wise to reach out to our team first to confirm.

Same Fuel System Requirements

All of EFI systems require a minimum fuel pressure of 42PSI and either come setup with -6 or -8 AN fittings. All of our fuel delivery systems are compatible with any of our EFI systems.

Hall Effects, CDI, and boost compatible.

Yes. Correct. So true. 100%. We love it.

Optional built-in CDI

Both of our TBI and Multi-Port systems have versions that have EFI & CDI built into one ECU. ACES is the only EFI company that offers a system like this.

Throttle Body Injection

TBI

Due to it's affordability and ease of install, TBI systems are the most common EFI types for people who want to switch from a carburetor to EFI. Our TBI systems come in 2 or 4 bbl kits, supporting up to 350 or 650 hp (NA) and are perfect for 4-8 cylinder engines.

TBI Specific Features

3-bar TMAP Sensor

Built into the throttle body for boost & nitrous compatibility (using our free laptop software).

Flange Fitment Options

Somewhat of a universal fitment and designed with many applications in mind, we offer 2-bbl systems with a 2300 style flange that support up to 350hp* and 4-bbl systems with a 4150 style flange that support up to 650hp*

*Naturally aspirated

Fuel Injectors

Our 2-bbl systems utilize (2) 100 lb/hr injectors while our 4-bbl systems utilize (4) 100 lb/hr injectors.

Built into the throttle body for boost & nitrous compatibility (using our free laptop software).

Multi-Port

Offering greater flexibility for tuning, the ability to manage individual cylinder trim, and higher horsepower limits (if you upgrade injectors, throttle body, etc.), our multi-port EFI systems for 8 cylinder engines offer greater customization, while still being very intuitive and easy to install for the average enthusiasts.

Multi-port Specific Features

Sequential EFI

True sequential EFI for individual level cylinder trim, unlike the bank to bank multi-port systems on the market.

8 Injectors

Utilizing (8) EV6 Pico style injectors for increased power, you can also upgrade to bigger or smaller ones depending on your HP needs.

Hall Effects Distributor

Our multi-port systems use our Gambler Series Distributors that are 7+1 Hall Effects Distributors.

True sequential EFI for individual level cylinder trim, unlike the bank to bank multi-port systems on the market.
