• Reliable, easy to install and operate.
• Overdesigned using the highest-quality automotive and industrial grade electronic components that far exceed the operating ratings and life cycle of the OEM electronic modules
• Fully manufactured and tested in Canada

Torqbyte PM5 is an advanced microprocessor-controlled brushless low-pressure fuel pump (LPFP) controller. It was designed to be a complete Plug-n-Play, drop-in replacement for the OEM fuel pump PWM control module. PM5 is used to provide increased fueling in returnless direct injection fuel systems on upgraded EA825 setups.

PM5 is capable of continuously supplying the OEM fuel pump with up to 40A of current.

While the PM5 increases the capacity of the OEM fuel pump, its electronics interface directly with the ECU ensuring no diagnostics trouble codes are generated. Torqbyte's innovative technical approach built into the PM5 allows the ECU to maintain full control of the aftermarket LPFP operation and maintain the closed-loop fuel pressure control mechanism that the vehicle was originally designed with. This crucial feature is something that _none_ of the other LPFP "upgrades" currently on the market are able to offer.

Because it interfaces directly with the ECU, PM5 is able to live-stream the ECU commanded duty as well as pump actual duty, over USB, to a laptop running the free Torqbyte TorqBLPM Windows software. These logs can be very useful in identifying tuning issues or diagnosing mechanical fuel system problems.

Plug-n-Play Wiring

All EA825 kits are provided with custom-made PnP wire adapters that provide seamless integration with factory wiring without the need to cut or splice anything. This provides cleaner and more reliable electrical connections and also means that a vehicle can be returned to factory configuration, if required.

LPFP Voltage Boosting

The PM5 with Integrated Voltage Boosting includes an advanced quad polyphase synchronous voltage booster that raises the incoming battery or alternator voltage and  supplies the pump with a variable voltage of 15Vdc to 24Vdc. The output voltage level is user-adjustable and is maintained even when the input voltage (from the battery or alternator) dips down to as low as 8Vdc.

Voltage-booster voltage can be kept static  at a fixed value or can be configured to track engine throttle position readings obtained over CANBus. 

Flow Test Results

• PM5 with Integrated Voltage Boosting 

TorqBLPM Windows Software

PM5's operation can be configured or reconfigured using the provided USB Cable together with free TorqBLPM Windows software.

TorqBLPM is intuitive and easy to use and allows the user to configure all aspects of the PM5 and its voltage booster. The user can fine tune the behavior of the pump in response to an input command (which can be derived from an ECU's PWM signal, a MAP sensor (or another 0-5V signal source), or over CANBus). Additionally, the behavior of the voltage booster can also be configure to be either static, switched between 2 preset levels or adjusted progressively based on a MAP sensor (or another 0-5Vdc signal source).

Multiple configurations can be saved and shared making remote tuning very easy.

In addition to configuring the PM5, feature-rich TorqBLPM software also includes Live-Viewing, Data-Logging and Log Visualization functions. 

Power, Ground and Pump Connections

The voltage-boosted PM5 requires a dual fused 40A connection to the battery +ve terminal and a dual solid connection to the nearest vehicle chassis ground.

As with the standard PM5, the pump wires should be kept as short as possible keeping in mind that the PM5 is not sealed and MUST be mounted inside the vehicle.

The torqbyte_ Advantage

PM5s are 100% manufactured in Canada and the United States. We use authentic components sourced from manufacturer-authorized distributors and our only offshore import are wire adapters and connectors from OEM suppliers in Germany. We assemble everything using only manufacturer-recommended tooling, procedures and automotive-grade materials. 

PM5 is housed in a rugged, thermally-conductive, CNC machined aluminum enclosure that is hard anodized for maximum durability.

Torqbyte PM5 wiring only use US-Spec SAE J1127 SXL and TXL or European-Spec FLRY automotive wire with annealed stranded copper conductors and premium-grade abrasion, chemical and moisture resistant, high temperature Crosslinked Polyethylene insulation.

All pump power adapters are supplied with the thickest possible wire gauge for the given connector family ensuring minimum line loses and maximum power transfer to the LPFP.

• Unit Mounting and Thermal Considerations

The unit is not sealed. It must be installed on the interior of the vehicle and not be exposed to any condensing moisture or debris.

The unit may get warm. I should not be covered with thermally-insulating material (such as carpeting or seat cushion foam).

Ideally, the Voltage-Boosted PM5 should mounted directly to a large metal panel/surface in order to aid its heat dissipation.

• Dual Pump Control

If additional fueling is required, a second PM5 (either standard or with integrated Voltage Boosting) can be added and configured as a "slave" which is controlled from the primary "master" controller. The configuration parameters for both controllers is entered only into the master controller, so that both pumps respond to the same ECU signal. Operation of the two pumps can be configured completely independently from one another, but since the ECU must stay in full control of both pumps at all times, only the master controller receives the control signals from the ECU and relays commands to the leave controller in accordance with the slave table loaded into the master controller's configuration. If the slave controller has an integrated voltage booster, the master controller will ensure the secondary pump's boosted voltage rises and falls in accordance with its own.

A special harness is required to connect the two controllers together,

Note: Torquebyte controllers are ordered through and fulfilled by torquebyte_ and any post sale service will be administered by them directly.
