Unleash the Hidden Performance
The factory Bosch Motronic calibration leaves considerable performance untapped. OE Match software unlocks stronger low and mid-range torque, sharper throttle response and improved drivability, eliminating the familiar flat spot below 4,000 rpm while delivering dyno-proven horsepower gains.
The result is a 964 that feels noticeably more responsive, pulls harder from low engine speeds and offers the kind of immediate throttle response that transforms both road and track driving.
Developed for Your Exact Configuration
Every OE Match chip has been extensively developed through dyno testing and real-world road evaluation using premium pump fuel. Unlike generic performance chips, each calibration is matched to your vehicle's specification, ensuring safe air-fuel ratios and optimum performance.
Suitable for:
- Porsche
964 Carrera 2 & Carrera 4
Manual
and Tiptronic transmissions
- Factory catalytic converter
- Standard rear silencers
- Primary or secondary muffler bypass pipes
- Factory or RS lightweight flywheel
Dyno Developed for Real-World Driving
Unlike generic replacement chips, OE Match calibrations are written specifically for each engine and exhaust configuration.
Every program has been extensively developed through
hundreds of hours of dyno tuning, road evaluation and real-world testing using
everyday pump fuel. Ignition timing, fuel delivery and throttle mapping have
all been optimised to deliver:
- Smoother idle
- Increased low and mid-range torque
- Sharper throttle response
- Elimination of the factory sub-4,000 rpm flat spot
- Stronger acceleration throughout the rev range
- Dyno-proven horsepower gains
- Improved everyday drivability
Unlike inferior calibrations, OE Match software maintains safe air-fuel ratios, ensuring the engine continues to run efficiently while avoiding the lean conditions that can reduce performance and increase knock sensor activity.
Includes the Lightweight Flywheel (LWF) Fix
This software includes the latest LWF fix, eliminating the stalling and RPM dip commonly associated with lightweight flywheel conversions. It also improves clutch engagement and throttle response while remaining fully compatible with standard flywheel cars.
OE Match chips are developed from completely new software, not modified factory maps. Hundreds of hours of dyno development and road testing have produced a calibration that delivers smoother idle, stronger torque, improved throttle response and outstanding drivability without triggering the Check Engine Light.

OEMatch Ignition Control Units — Fit, Function, Confidence
OEMatch offers ignition control units tailored for Porsche models, helping maintain reliable spark timing across air-cooled and water-cooled engines. These modules regulate coil charging and ignition sequencing to support starting, smooth acceleration and steady fuel consumption in everyday and performance driving, and OEMatch focuses on parts for Porsche applications.
Available Types
- Replacement ignition control modules for direct replacement
- Remanufactured units where specified
- Diagnostics and testing references for electrical faults
Understanding OEMatch Ignition Control Units
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original ignition control units. OE (Original Equipment) refers to parts matching original specifications for the ignition control units and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM ignition control units engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. An ignition control unit receives timing information from crank and cam sensors, controls coil charging and release, and coordinates with engine management to shape combustion. Correct operation reduces misfires, supports emissions regulation systems and preserves coil life; faults can cause hesitation, rough idle or a no-start condition.
Benefits Include
- Consistent spark timing for smoother throttle response
- Improved starting reliability and reduced misfire risk
- Protection for coils and related ignition components
Why Ignition Control Units Wear and Fail
- Thermal stress from prolonged engine heat exposure
- Electrical overloads, short circuits or voltage spikes
- Corrosion or damaged connectors and wiring
The Importance of Replacing with OEMatch Ignition Control Units
Replacing a faulty ignition control unit early helps maintain engine response and can prevent secondary damage to coils and sensors. Selecting an OEMatch ignition control unit means choosing a unit matched to Porsche electrical characteristics and mounting provisions so the module integrates with existing wiring, sensors and engine management routines.
Advantages
- Parts selected for compatibility with Porsche ignition systems
- Electronic assemblies produced to manage heat and vibration
- Part numbers cross-referenced for easier identification
