Revolutionize Your Porsche’s Performance with Unmatched Reliability

Elevate your Porsche experience with the cutting-edge Porsche Solid-State DME Relay – the smart choice for Porsche enthusiasts.

This innovative upgrade replaces old, failure-prone mechanical relays in your Porsche 924 S, setting a new standard in vehicle reliability and performance.

Proudly Designed and Manufactured in the USA


*LED lights Diagnostics Feature

Gain immediate insights into your Porsche's health with the intuitive LED indicator system on the Solid-State DME Relay.

This system includes four distinct LEDs, each representing a crucial aspect of your vehicle's functionality: ignition signal, fuel injection system power, fuel pump control signal, and fuel pump activation.

When all four LEDs are lit, it's a clear sign your Porsche is in optimal condition.

Conversely, if any LED is unlit, it promptly alerts you to potential issues in the corresponding circuit.

Ignition SW – (Yellow) Input signal to power up the fuel injection system and enable fuel pump control.
Fuel Inj. Power – (Red) Output indicating the fuel injection system is powered up.
Ctl. Fuel Pump – (Blue) Input signal indicating the DME has commanded the fuel pump on.
Fuel Pump – (Green) Output indicating the fuel pump is powered up.


Top Mechanical Relay Failures
#1 Cracked Solder Joints
As the engine vibrates, the heavy mass of a mechanical relay can eventually fatigue the solder joint connections leading to fractures. This Solid-State Relay is less than half the weight, and therefore, vibrates with the engine rather than against it. Our Solid-State Relay’s solder connections will never fatigue and therefore, cannot crack.

#2 Burned Contacts
Every time a mechanical relay engages, electrical arching occurs as the contacts close. This arching slightly burns the contacts and over time increases contact resistance. Higher resistance in the contacts means the entire relay heats up (including the solder joints) and will make cracked solder joints more likely. Solid-state relays do not have mechanical contacts and do not “wear out” with use.

#3 Burned Coils
Mechanical relays have coils of finely wrapped copper wire with thin insulation. On occasion, the insulation fails, and the coil internally shorts leading to burn-out. Solid-state relays do not have a coil of wire and cannot fail in this way.

#4 Poor Quality Control
Cheap aftermarket relays are built with no quality control. The defect rates are extremely high and commonly include poor soldering, unsoldered connections, damaged solder pads (from poor soldering), missing parts (like return springs), metal debris (trimmed resistor/diode legs), and bent/misaligned armature.


Key Features
• Solid-State Relay, no moving parts
• Cannot "wear out" like mechanical relays
• Premium high-quality product
• 5-year warranty
• Every relay inspected and tested
• Designed and manufactured in the USA


relay location

Designed for simplicity, this solid-state relay can be installed in just minutes, making it perfect for both seasoned enthusiasts and DIY beginners.

The DME relay is locate next to the DME under the driver seat.

Use a 10mm socket or wrench to remove holding bolt.

Replace the Old DME relay by carefully disconnecting plug and Re connecting to new one.

Re install the 10mm holding bolt and make sure engine operates correctly.
