This kit is a modern update to the 964 (911) ignition system. This system takes the management of the car into the digital age and allows greater control over ignition and fueling.

The kit will replace your restrictive old fashioned air flow meter (barn door) with a modern MAP sensor managed by intake pressures.

The kit is delivered ready to use with a PPT ignition map. We have maps for 3.6 and 3.8 conversions, and either can be pre-installed for you.

Our latest kit now comes with an upgraded ECU and can run a wide band sensor (oxygen sensor).
Our kits include this capability but the sensor needs to be ordered separately.

While developing the upgraded ECU we also changed our intake pipe; this now works with the factory airbox, gives a stock appearance in the engine bay and houses the map sensor and air temp sensor out of sight.

Kit includes:
• Delta 700 ECU
• Direct plug in wiring loom
• Map Sensor and air temp sensor
• Air intake pipe
• 6 Bosch injectors
• Vacuum pipe and T connector
• Support and service by PIE Performance
• Can Bus data connection tool

All our kits are 100% reversible, with no need to drill or alter components, we utilise what already exists

The corresponding Bosch part numbers is 0 265 005 100 or F 026 T00 500

These devices use a very old technology involving a swinging pendulum and a Hall sensor. They are increasingly prone to failure.
This completely re-engineered equivalent uses a solid state acceleration sensor and precision signal processing with no moving parts. Its mountings are compatible with the unit it replaces.

About Electronic Control Units

Electronic Control Units (ECUs) – Precision Performance and Reliability for Porsche Vehicles

Electronic Control Units (ECUs) are the brains of your Porsche’s electronic systems, managing and monitoring everything from engine performance to fuel delivery, ignition timing, transmission response, and emissions control. These highly sophisticated modules communicate with multiple sensors and actuators to ensure your car runs efficiently, safely, and smoothly under all driving conditions.

At Design911, we supply a wide range of genuine and high quality ECUs for Porsche models - including engine control units, transmission control modules, body control units, and more. Each ECU is manufactured to the highest standards, ensuring exact compatibility and seamless communication with your vehicle’s electronic architecture.

What Do Electronic Control Units Do?

An ECU acts as the central processor of a vehicle’s system, interpreting data from sensors and adjusting performance parameters in real-time. Depending on the application, ECUs can control:

  • Engine management: fuel injection, ignition timing, turbo boost, and air-fuel ratios.
  • Transmission systems: shift points, torque converter lock-up, and gear selection.
  • ABS and traction control: maintaining grip and stability.
  • Body systems: lighting, climate control, and interior functions.

Modern Porsche vehicles often contain multiple ECUs working together across a CAN bus network, ensuring optimal efficiency, emissions compliance, and driver comfort.

Why Do ECUs Fail?
Electronic Control Units are robust, but can fail due to age, environmental factors, or electrical faults. Common causes include:

  • Water ingress or corrosion: damaging internal circuits.
  • Voltage spikes or short circuits: caused by battery or alternator issues.
  • Thermal stress: from prolonged engine heat cycles.
  • Software corruption or data errors: due to low voltage or improper programming.
  • Connector and harness faults: causing poor communication with sensors.

Symptoms of ECU failure may include engine misfires, warning lights, poor performance, stalling, or failure to start.

Why replace your ECU?
A faulty ECU can cause unpredictable performance, poor fuel economy, and safety concerns. Replacing a malfunctioning unit restores the precision and reliability your Porsche was built to deliver.

Benefits of replacing with a quality ECU include:

  • Full compatibility with vehicle systems.
  • Restored factory performance and efficiency.
  • Elimination of warning lights and diagnostic faults.
  • Improved reliability and drivability.
