Introduction

The Syvecs OEX (Oe Ecu eXpander) is a powerful expander module enabling advanced after market features on existing OEM engine management systems via CAN/CANFD communication. By utilising the well proven Syvecs X20 hardware which was born in 2020, a version of the software has been created to provide our Syvecs market leading features into the Oe Ecu eXpander package. This provides the best solution for clients who need to expand the capabilities of an original ecu control module or to integrate with another engine control unit (Master).

Features

  • 12 x Sequential injectors with closed loop feedback from Onboard lambdas or OEM readings
  • Internal or External Fuel Calculations from multiple internal sources or external CAN targets from and OEM ECU (Master ECU)
  • Live calibrating from SCAL software via USB C
  • 2 x NTK Lambda Circuits for close loop fueling with option to pickup lambda targets from OEM ECU (Master ECU)
  • Dual Wastegate Control with option of internal targets or external targets from OEM ECU (Master ECU)
  • Dual Knock Control Circuits to externally monitor, warn and feedback to the OEM ECU (Master ECU)
  • USB Datalogging to PC or External Memory Stick (up to 4000 times a second!)
  • Flex Fuel Controls, change Injection parameters, boost targets and more
  • Nitrous Control, wet or dry strategies with bottle pressure control
  • External DBW Strategy for Older cars which want to add Drive by wire support
  • LimpMode strategies with option to bring OEM ECU light on, adjust sensor voltage outputs to OEM ECU, lower boost targets, enable outputs and Limp CAN Messages
  • Water injection Control with safety strategies for Level, Pressure and Flow from our WMI Module
  • OBD2 Support - Pick up many OEM sensor readings including Lambda, Ignition Timing, Temperatures, MAF etc
  • Lean lambda trip from our standalone Engine Control Module to add protection
  • Traction Control calculation done internally on the OEX to reduce boost and send torque reduction the OEM ECU (Master ECU)
  • Signal rescaling / clamping on 4 x DAC outputs to modify signals in the OEM ECU (Master ECU) like Manifold pressure sensors
  • 20 x Analog inputs with frequency, thermistor and ADC support
  • 20 x Output, 8 Half Bridge and 12 Low Side
  • CAN / CANFD Support
  • Optional FlexRay hardware available on request to allow all OEX functions on newer models of vehicles, software currently under development.
  • Crank and Cam Setup strategies from our Standalone Engine Control modules
  • CAN Bridging/Forwarding between 2 CAN Bus’s and ability to drop frames, then transmit own messages to keep OEM modules happy
  • Water Resistant
    and more

Extensive CAN integration

Syvecs is known industry-wide for our OEM/ECU CAN data capabilities, and the OEX is no exception. We have incorporated our most popular CAN database decodes into the OEX, allowing for direct communication with many powertrain CAN buses. This enables users to quickly retrieve information from their vehicle or aftermarket ECU, displayed in the OEX without the limitations of the OBDII protocol.

The OEX integrates with OEM Can bus systems in the following ways, all of which can be used to your advantage.

• Reading of OEM sensors such as Manifold Pressure, Air charge, Oil and Coolant temperatures.
• Reading of calculated loads such as Torque and Fuel trims, ignition advance and Load.
• Reading of measured values such as TPS, Speed and RPM, and OEM Lambda.
• Ability to manipulation the OEM CAN by forwarding through the OEX CAN0 and CAN1, Can then drop and modify data.
• The OEX can also produce can frames for sharing information such as LimpMode, enabling the OEM CEL light.
• OBD2 Communication to extract Data and also Clear DTCs or Enable modes such as DynoMode or ABS OFF

Triggered CAN messages are also available to send OEM diagnostic messages to clear DTCs.

If a vehicle/ECU is not listed, installers can use our Generic CAN receive/transmit function and configure their own CAN communication.

Syvecs OEX buyer guide

The Syvecs OEX is an OEM ECU expander. It adds control functions alongside an existing OEM or other master ECU through CAN/CAN FD communication; it is not a replacement standalone engine ECU.

Start by identifying which controller will remain in charge of the engine and which functions you want OEX to add. Confirm the vehicle's CAN messages, sensor requirements and supported control strategy with your installer.

Syvecs OEX FAQ

What is the Syvecs OEX used for?

OEX adds functions to an existing OEM or other master ECU using CAN/CAN FD communication. It is an expander, not a standalone replacement ECU.

Is the OEX the same as a full standalone ECU?

No. OEX works alongside a master ECU. If you need standalone engine management, compare S7 Plus, S7D, S8C and S12 against the engine and wiring requirements.

What should I pair with a Syvecs OEX?

Choose supporting displays, sensors and power-distribution hardware for the functions you need. Confirm CAN communication, wiring and electrical requirements before ordering.
