Jackpot 2 LS EFI System - Top End Kit (500 HP)

Modern EFI control, built for the heart of every LS engine.

The Aces Jackpot 2 LS EFI System is a cutting-edge, self-learning engine management system designed specifically for GM LS-based engines. It delivers the perfect balance of affordability, simplicity, and high-end performance, ideal for both professional builders and hands-on enthusiasts.

Compatible with LS1, LS2, LS3, LS6, LS7, and LS9 engines (excluding VVT and DOD applications), the Jackpot 2 LS replaces stock ECUs or other aftermarket EFI systems when you want greater control and true customization of your build.

Advanced Engine Control Technology

At its core, the Jackpot 2 ECU runs on Aces’ 32-bit Power Architecture, an OEM-grade platform that ensures superior I/O management, voltage regulation, and RPM stability. The result is faster, more consistent control across all engine conditions compared to competing 16-bit aftermarket systems.

The Jackpot 2 LS EFI System supports a wide range of engine and transmission configurations and is available in the following standalone options:

• Drive-by-Cable & Manual Transmission
• Drive-by-Cable & Transmission Control
• Drive-by-Wire & Manual Transmission
• Drive-by-Wire & Transmission Control

By default, all versions support drive-by-cable throttle bodies and manual transmissions.

For automatic setups, transmission control currently supports:

• 4L60E
• 4L80E

Ease of Use and Tuning Options

For stock and mild performance applications, the system’s intuitive calibration wizard and self-learning fuel strategy eliminate the need for advanced tuning skills. For high-performance builds, Aces provides a free full-featured tuning suite and a USB data cable for manual tuning, giving you total control when you need it.

• Throttle Body Options (Top-End & Master Kits):
  • 4-barrel throttle body with 1.0 BAR MAP sensor (N/A)
  • Single-blade throttle body with 2.7 BAR MAP sensor (boosted)
• Dual Wideband O₂ Sensors: Monitors both banks (each using 31x31 tables) for balanced fueling and precision.
• Manifold Fitment: Designed for OEM-style LS blocks and heads (fitment may vary).

Already compatible with blow-through, draw-through, and nitrous applications. PWM boost control update arriving Fall 2025, hardware ready.

Power Meets Simplicity

At Aces, we build EFI systems that make serious power simple.

The Jackpot 2 LS is DIY-friendly and designed for enthusiasts of all skill levels. Wire it up, answer a few setup questions, fire it up, and the self-learning ECU takes care of the rest. For tuners pushing the limits (high-lift cams, nitrous, or forced induction) our free laptop software unlocks complete manual control. Once your engine reaches temperature, the system goes closed-loop and begins learning in real time. After a few drives, your tune dials itself in, and when you’re satisfied, you can lock it down.

That’s confidence you can feel at every throttle blip.

Ignition Compatibility

The Jackpot 2 LS is built for precision ignition control and supports both:

• 58x/4x crank and cam reluctor combination
• 24x/1x configurations

for true sequential fuel and spark management. For a complete Aces system, we offer LS-style ignition coils and fuel components engineered for maximum spark reliability and performance.

Interface Options

Choose how you want to set up and monitor your system:

• Bluetooth Module: Connects to Android (iOS support coming Fall 2025) through the free Aces Connect app.
• 5” Handheld Touchscreen: Full-color display with built-in GPS for real-time MPH and live data.
• 7” Handheld Touchscreen: Larger screen, same great features, also GPS-ready.

All interfaces provide live access to RPM, speed, sensor data, tuning metrics, and customizable dashboards. Bluetooth users will gain GPS speed readouts via the Fall 2025 firmware update.

System Integration

The Jackpot 2 LS integrates seamlessly with Dakota Digital clusters using the Aces BIM-01-2-ACES module (sold separately). It provides a clean tach signal for factory and aftermarket gauges and supports systems that don’t rely on CAN bus.

If you’re replacing a stock or aftermarket EFI that uses CAN-based gauges, check compatibility before installation.

All Aces ECUs use 32-bit automotive-grade processors, the same technology found in OEM systems, not the slower 16-bit chips common in other aftermarket units.

The system operates between 43–60 PSI fuel pressure and supports return or returnless configurations, depending on your pump type. Internally regulated in-tank pumps can run returnless, while external or surge systems require a return line.

Easy Weekend Install

The Jackpot 2 LS was designed for enthusiasts who want performance without the hassle. For most applications, it installs in a weekend: bolt it on, wire it up, answer a few setup questions, and let it learn. When you’re ready to leave stock limitations behind, the Jackpot 2 LS delivers everything you love about LS performance, with all the intelligence and flexibility of modern EFI.

No compromises. No headaches. Just results.
