Proton Satria Neo 1.6 Campro CPS Engine ECU 0508 Description:

The Proton Satria Neo 1.6 Campro CPS (Cam Profile Switching) uses a Mitsubishi-based ECU labeled 0508, designed to control the performance of the Campro CPS engine variant.

🔧 ECU 0508 Overview:

• ECU Code: 0508 (common code printed or labeled on the ECU unit)
• Type: Engine Control Unit (ECU)
• Platform: Mitsubishi-type ECU (based on the Mitsubishi E6T series)
• Location: Installed in the engine bay near the firewall or cabin side (depending on market)

⚙️ Engine Compatibility:

• Engine: 1.6L Campro CPS (S4PH with CPS system)
• Technology:
  
• CPS (Cam Profile Switching)
• VIM (Variable Intake Manifold)
• DOHC 16-valve, MPI fuel system
• 
  

📊 Functions Controlled:

• Variable cam profile engagement (CPS solenoid)
• Intake runner switching (VIM actuator)
• Fuel injection timing and quantity
• Ignition timing
• Idle control and throttle response
• Knock sensing and adaptive timing
• Emissions control (EGR, O2 sensor input)
• Cooling fan and temperature sensors

🛠️ Common Issues:

• ECU failure due to water ingress (in older units)
• CPS solenoid or VIM actuator error codes (if wiring or ECU output fails)
• Compatibility problems with non-CPS engines or standard Campro units

🔄 Interchange & Tuning:

• Cannot be interchanged directly with IAFM or non-CPS ECU (different cam control logic)
• Can be remapped using tools like EcuFlash + tactrix cable, but with skill
• Tuners often reflash for better mid-range torque and smoother CPS engagement
