Doctronic ProECU-K Sensors & PNP Cable Kits

Doctronic ProECU-K Sensors & PNP Cable Kits

Product Overview

The Doctronic ProECU-K Sensors & PNP Cable Kits are designed for customers who want to add extra monitoring capability to their ProECU-K engine management system.

These sensors are ideal for Honda K-Series, D-Series, S2000, K-swap, turbo and track-focused builds where accurate engine data is important for tuning, diagnostics and engine protection.

Each sensor package is supplied together with the correct PNP cable or adapter cable for use with the Expansion Box, making the installation cleaner and easier compared to building custom wiring from scratch.

For serious performance builds, additional sensors are not only useful for tuning. They also help the driver and tuner understand what the engine is doing under real load conditions, especially during fast road driving, trackdays, time attack sessions and turbo applications.

What the Sensor Packages Do

The Doctronic sensor kits allow the ProECU-K system to monitor additional engine parameters such as intake air temperature, fluid temperature, fluid pressure, exhaust gas temperature and manifold pressure.

Depending on the selected sensor, these values can be used for datalogging, diagnostics, calibration review and engine safety strategies.

When used together with the Doctronic Expansion Box, external sensors can be connected to the ProECU-K system and configured inside the software.

Sensor Packages Available

• Open Element IAT Sensor + Adapter Cable: Used for accurate intake air temperature monitoring, especially useful on custom intake setups, turbo builds and applications where the original IAT sensor position is no longer ideal.
• Fluid Temperature Sensor + PNP Cable: Used for monitoring oil temperature, coolant temperature or other fluid temperature points depending on installation.
• Fluid Pressure Sensor 10 Bar + PNP Cable: Used for monitoring oil pressure, fuel pressure or other fluid pressure points depending on the application.
• Bosch Combined Temp & Pressure Sensor + PNP Cable: A compact solution that measures both fluid pressure and fluid temperature from one sensor body, reducing the number of separate sensors and wiring points needed.
• EGT Probe 3mm, 2.5m Cable: Used for exhaust gas temperature monitoring, especially useful on turbocharged engines and high-load track applications.
• K-Series PNP 4 Bar MAP Sensor: Plug-and-play 4 Bar MAP sensor for K-Series applications that require a higher manifold pressure measurement range than the factory sensor can provide.

Why Add External Sensors?

A performance ECU setup is much more effective when it has access to the right data.

On modified engines, especially turbocharged or track-driven setups, the factory sensor package is often not enough. Extra sensor information allows the tuner to see what is happening with oil pressure, fuel pressure, oil temperature, intake temperature, exhaust temperature and boost pressure.

This information is extremely useful when checking the health of the engine, verifying the fuel system, setting safety limits and reviewing datalogs after hard driving.

For customers running ProECU-K, the correct sensor setup can make the difference between a basic tune and a properly monitored performance package.

Key Features & Benefits

• Useful for Engine Protection: Additional sensor data can support safety strategies and warning limits.
• Ideal for Turbo Builds: Perfect for monitoring fuel pressure, oil pressure, EGT and boost pressure.
• Recommended for Track Use: Helps monitor critical engine values under sustained load.
• Suitable for Street and Motorsport Builds: Useful for fast road, trackday, time attack and race cars.
• Works with ProECU-K Expansion Box: External sensors can be connected and configured through the Expansion Box where required.

Available Sensor Package Details

• Open Element IAT Sensor + Adapter Cable
  The open element IAT sensor is used to measure intake air temperature more accurately in custom intake or boosted applications.
  It is especially useful when the factory IAT sensor location is no longer suitable due to intake manifold changes, turbo piping, intercooler routing or custom engine conversion work.
• Fluid Temperature Sensor + PNP Cable
  The fluid temperature sensor is suitable for monitoring oil temperature, coolant temperature or other fluid temperature points depending on installation.
  This is a useful sensor for trackday and performance cars where temperature control is important during hard use.
• Fluid Pressure Sensor 10 Bar + PNP Cable
  The 10 Bar fluid pressure sensor is suitable for oil pressure, fuel pressure or other pressure monitoring depending on the installation point.
  For performance engines, oil pressure and fuel pressure are two of the most important values to monitor. A drop in either one can quickly become dangerous for the engine.
• Bosch Combined Temp & Pressure Sensor + PNP Cable
  The Bosch combined sensor measures both temperature and pressure in one compact sensor body.
  This is a clean solution for customers who want to monitor both oil pressure and oil temperature, or fuel pressure and fuel temperature, while reducing the amount of wiring and sensor ports needed.
• EGT Probe 3mm, 2.5m Cable
  The EGT probe is used for exhaust gas temperature monitoring.
  This is especially useful on turbo engines, where exhaust temperature can give important information about engine load, ignition timing, fuel mixture and turbo system behaviour.
• K-Series PNP 4 Bar MAP Sensor
  The K-Series PNP 4 Bar MAP sensor is designed for applications that need to measure higher manifold pressure than the factory MAP sensor can handle.
  This is mainly used on turbocharged or supercharged K-Series engines where accurate boost pressure reading is required for tuning and safety.

Why Sensor Data Matters

• When tuning a modified engine, the ECU needs accurate information.
• Fuel and ignition maps are only part of the setup. To make a performance engine safer and more reliable, the tuner needs to see how the engine behaves under load, heat and pressure.
• Oil pressure shows whether the lubrication system is stable.
• Fuel pressure shows whether the fuel system is keeping up with engine demand.
• Oil and coolant temperature show whether the cooling system is suitable for the way the car is used.
• EGT helps evaluate exhaust temperature behaviour, especially on turbo setups.
• MAP sensor data is critical for forced induction applications where boost pressure must be measured correctly.
• For a serious street, track or turbo build, these sensors are a smart upgrade.

Installation Requirements

Professional installation is recommended.

Sensors must be installed in the correct mechanical location and wired to the correct ECU or Expansion Box input.

After installation, each sensor must be configured correctly inside the ProECU-K software. Sensor scaling, pull-up resistor values where required, input assignment and datalogging channels should all be checked before the car is driven hard.

For temperature sensors using thermistor-style output, the correct pull-up resistor must be used.

For pressure sensors, the correct 5V supply, ground and signal wiring must be confirmed.

For turbo or track applications, sensor installation should be tested and verified during the tuning process.

Important Notes

• These sensors are intended for monitoring, datalogging, diagnostics and tuning support.
• Correct calibration in the ProECU-K software is required.
• Sensor readings should be checked before relying on them for tuning decisions.
• Some sensors may require the Doctronic Expansion Box depending on ECU setup and available inputs.
• PNP cables simplify installation, but professional wiring and setup knowledge is still recommended.

JDMaster Recommendation

At JDMaster, we recommend adding external sensors to any serious ProECU-K setup.

For most performance Honda builds, oil pressure, oil temperature and fuel pressure are the first sensors we would recommend. These give important information about engine safety and reliability.

For turbo builds, we also recommend considering EGT monitoring and a suitable MAP sensor depending on boost level and tuning strategy.

For customers who want a cleaner setup, the Bosch combined temperature and pressure sensor is a very good option because it allows pressure and temperature monitoring from one sensor package.

If you are not sure which sensor package is correct for your build, contact JDMaster before ordering. We can help choose the right combination based on your engine, ECU, fuel system, turbo setup and intended use.
