Analogue Output Adaptor

Overview

Transform your Haltech ECU's PWM outputs into clean 0-5V analogue signals for driving gauges, dash systems, and aftermarket accessories that can't interpret PWM directly. Essential for professional builds where you need reliable analogue control of boost controllers, external wastegate controllers, or sophisticated dash displays that demand smooth analogue inputs.

Technical Specifications

• Part Number: HT-038000
• Input Signal: PWM (Pulse Width Modulated)
• Output Signal: 0-5V Analogue
• Conversion Type: Digital to Analogue
• Operating Voltage: 12V automotive systems

Why You Need This

Modern Haltech ECUs output PWM signals for auxiliary control, but many aftermarket components — particularly older boost controllers, some gauge clusters, and certain dash systems — can only read analogue voltage signals. Without this adaptor, you're stuck with incompatible control signals that result in erratic operation or complete failure of your auxiliary systems. This is particularly problematic on high-end builds running external wastegate controllers or sophisticated dash systems that expect clean analogue inputs.

We see this constantly on LS swap builds where customers want to retain factory-style gauge operation, or on RB25/RB26 and 2JZ builds running aftermarket dashes that need smooth analogue signals for boost display. The PWM-to-analogue conversion ensures your auxiliary systems receive the steady, predictable voltage signals they're designed for, eliminating the hunting and instability that comes from trying to use incompatible signal types.
