Description
Now’s the time to eliminate all the issues that come with the EKPM. This EKMP replacement board will replace your stock EKPM board. This does not require any additional wiring and uses the stock connectors. This seamlessly works with the stock DME, and standalone ECUs such as Maxxecu, and LSE9x Holley Canbox. The OEM EKPM fails regularly, especially in an engine-swapped car with upgraded pumps, because it’s not being regulated anymore. The stock EKPM is current limited and will limit current with PWM switching. This PWM control limits the voltage and causes heat to be generated.
The EKPM replacement board uses relays to directly control up to two fuel pumps. It has canbus support to emulate the stock EKPM and is capable of up to 25 amps per built-in pump. This board uses high-quality 45 amp relays from TE connectivity, and a grounded output that is configurable based on your pedal position, engine torque, fuel flow rate and is triggerable by a custom canbus message.
This EKPM replacement board includes several features including crash detection from the airbag modules that will turn off the fuel pumps in the event of a crash. The fuel pump(s) will not consistently run while the ignition is on and the engine is off. There is an additional relay control pin that will allow you to activate an external relay to control a third or more fuel pumps.
Versions
| NO CANBUS - Single Relay | The "NO Canbus" version activates the Relay when the 15_WUP (Ignition-on wire) is powered. This version is considered an EKPM delete/bypass due to the lack of canbus support. With this version you will have an active error code because the ECU will not recognize that there is an EKPM installed. |
| Canbus - Single Relay w/ switched ground | The Canbus - Single Relay version includes a switched ground wire that plugs into your stock EKPM connector which will allow you to trigger an additional external relay. |
| Canbus - Dual Relay w/ switched ground | The dual relay version includes a PNP secondary fuel pump wiring harness as well as the switched ground wire. With the dual relay harness, you can control up to three fuel pumps. |
Fitment Notice
The following EKPM part numbers will require trimming of the plastic cover for the relay(s) to fit. Please verify stock EKPM is at-least 4.2 inches long prior to ordering:
- 16147263392
- 16147268028
- 16147276046
The following EKPM part numbers do not fit as the board is too long. We are working on a billet enclosure for these:
- 16147407513
If your EKPM enclosure is too small, then add this EKPM enclosure on to your order. We will ship your EKPM as completed module (board installed in enclosure).
Planned Features
- M3 Kombi Shiftlight control
