Replaces Porsche Part#: 911.618.154.00

"Pump-Prime"
The Pump-Prime feature automatically runs the fuel pump for up to 3 seconds when the ignition is switched to the "On" position. This builds optimum fuel pressure before cranking the engine, insuring your Porsche starts as fast and as smooth as it possibly can.

“Diagnostics” (Optional Feature)
This optional feature allows you to instantly know the state of the DME Relay. It features four LEDs that are directly connected to the critical inputs and outputs of the relay. All four LEDs must be illuminated for the engine to start and run. If one or more LED(s) are off , there is an issue with the corresponding circuit.

Ignition SW – (Yellow) Input signal to power up 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.

Description
Replace you old failure-prone mechanical DME relay with this premium Solid-State upgrade. Because it has no moving parts, it cannot "wear out" like the original or aftermarket relays do. It can be installed in just a few minutes with just a 10mm socket wrench.

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 coils of wire and cannot fail in this way.

Cheap aftermarket relays are built in low-end Chinese factories with no significant 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. Every Solid-State Relay we sell is visually inspected under a scope and functionally tested at least twice by trained technicians. If you do not choose our relay, we recommend at least a good mid-range mechanical relay manufactured in Germany or Hungary. True OE (Original Equipment) relays from Porsche are the best mechanical option. OEM (Original Equipment Manufacturer) relays are of good quality, but not necessarily built to the same quality specification as the true Porsche OE version.
