Power Distribution Module (PDM)
Discover the next evolution in performance and reliability with the Aces Fuel Injection Power Distribution Module (PDM) —your ultimate solution for seamless power management in high-performance EFI systems. The PDM uses IGBT transistors in the place of solid state or electro-mechanical relays which helps to filter bad transient voltage, ultimately providing greater protection for your electronics which are connected to the PDM.
Our PDM is engineered to integrate effortlessly with Aces Fuel Injection Systems, providing robust, efficient power distribution for essential components such as:
- Ignition Systems
- Fuel Pumps
- Cooling Fans
- Auxiliary Accessories
Key Features
- Comprehensive Power Management: Supports ignition, fuel pumps, fans, and more.
- Simplified Wiring: Clearly marked terminals for ease of installation.
- Enhanced Safety: Fuse-protected circuits for optimal performance and reliability.
- Flexibility: Tailored control for auxiliary devices with relay support.
Pressure Sensor Kit
Aces EFI pressure sensor kits utilize top-quality parts for use with EFI systems. Kits include plastic/steel sensors with 1/8" -27 NPT threads and include a -6 AN fuel pressure take-off adapter fitting and 2 sets of 45 push lock hose ends.
Pressure sensors are great for logging oil pressure, fuel pressure, or boost pressure. Display the pressure reading on any Aces Handheld or Dash screen and on your data log files!
EGT CAN Module Kit
High-Performance Tuning with the Aces EGT Module
When it comes to high-performance tuning, accurate Exhaust Gas Temperature (EGT) monitoring is crucial. Whether you're running a naturally aspirated, turbocharged, or nitrous-fed setup, precise temperature data helps you optimize fuel tuning, prevent engine damage, and maximize efficiency. The Aces EGT Module is built for precision, durability, and seamless integration, ensuring you get real-time data to fine-tune your engine like never before.
Why You Need the Aces EGT Module
- Prevent Engine Damage – High exhaust temperatures can lead to pre-detonation, melted pistons, and turbo failures. Monitoring EGTs allows you to adjust fueling and timing before damage occurs.
- Optimize Air/Fuel Ratios – Fine-tune your AFRs based on real-time EGT data for better power, efficiency, and reliability.
- Monitor Cylinder Balancing – Detect uneven fuel distribution or ignition issues to avoid power loss and potential engine stress.
- Essential for Forced Induction & Nitrous Builds – Turbocharged, supercharged, and nitrous-fed engines run hotter. Accurate EGT readings ensure you're not pushing past safe limits.
- Seamless Integration with Aces EFI Systems – Easily expands via CAN connectivity to work with all Aces controllers and displays.
Aces EGT Module Features
- 32-bit RISC-V Core Processor – Ultra-fast processing for real-time data accuracy.
- 480MHz Multi-Stage Pipeline Processor – Handles high-speed temperature changes with precision.
- Hardware Floating-Point Unit (FPU) – Ensures stable, high-speed calculations for consistent performance.
- 16-bit ADC for High-Precision Signal Acquisition – Delivers accurate, reliable temperature readings.
- Supports 2 or 4 EGT Channels – Ideal for both single-bank and dual-bank monitoring setups. (2 channels for two banks, 4 channels for one bank but 4 per exhaust runner)
- Automotive-Grade Type N Thermocouple Sensor – High-durability sensor for extreme conditions.
- Wide Temperature Measurement Range – Capable of reading from -150°C to 1024°C with a rapid 150ms response per channel.
- High-Quality Construction – Silicone fiberglass sleeve, PTFE insulation, and Type N thermocouple conductor ensure long-term durability.
- CAN Expansion Accessory – Easily integrates with all Aces EFI units and display modules.
The Aces EGT Module is an essential tool for serious tuners and racers looking for accurate exhaust temperature data, better tuning capabilities, and enhanced engine protection. Take control of your performance with real-time monitoring and seamless EFI integration.
Low Profile Design
A smaller footprint design makes it easier to work with drop-base air cleaners.
Progressive Linkage
Ensures a more gradual and less jarring tip-in response.
650 HP
Single Throttle Body¹
1,200 HP
Ran as dual quads²
Fuel Pressure Sensor
Built-in for less plumbing hassle and a precise reading of your fuel pressure at all times, displayed in the handheld.
Secondary Throttle Body Connection
Enables the use of a dedicated secondary unit³ making the system expandable for dual quad options.
(Requires purchase of secondary unit available early Spring 2025)
Hold your horses
Supporting up to 650 HP and expandable to 1,200 HP by using a dedicated secondary unit, the Killshot II is capable of holding down the fort, and the horses.
Boost it, baby.
The Killshot II has a built in 3-bar TMAP sensor that allows you run draw through or blow through setups and support up to 27 lbs of boost.
Twice the Killshot. Twice the resolution.
Introducing the 3rd generation of our 5" Handheld, now in full 1080 HD. This new generation of handheld is built on a 64-bit RISC-V core processor. This means that graphics load faster, clearer, and smoother, much like a modern smartphone.
If the shoe (throttle body) fits
The Killshot II still uses the common 4150 style flange found on many classic engine manifolds making it a very versatile when it comes to compatibility. As long as the TBI unit fits, is within the appropriate HP range, and your engine uses a classic distributor, it's a match made in heaven...or the garage.
Know with the flow
A built-in pressure sensor gives you real-time, accurate fuel pressure readings at the throttle body, ensuring optimal performance and peace of mind—no guesswork, just precision.
