VEMS utilizes an advanced microprocessor and surface mounted component technology, with state of the art electronics to allow you to precisely control your engine. Ask your regional VEMS dealer for more information VEMS is manufactured in the E.U. Sensors VEMS can be configured to use almost any standard OEM sensor for:
  • Throttle position
  • Coolant temperature
  • Air temperature
  • Crank and Cam sensors - configurable for the standard OEM configurations such as Ford 36-1, GM/Bosch 60-2, Audi 5 cylinder 135 tooth as well as being customizable for many different timing strategies
  • Manifold Pressure through a choice of built-in pressure sensors, or an external OEM type
  • External fuel and exhaust pressures
Additionally VEMS also has the built in ability to control:
  • Integrated Wideband O2 Controller utilizing the low cost Bosch LSU4 sensor
  • Up to 2 Exhaust Gas Temperature sensors
Drivers/Outputs Throughout the development of VEMS, Customization has been the focus. The number of driver channels are as plentiful as the ways of configuring their operation. Outputs can be triggered by temperature, rpm, throttle position, or air pressure. 6 Low current drivers providing control for relays (fuel pump, fan, water pump) or lights (shift light, activation light, MIL) 8 High Current solenoid drivers that can be configured to control:
  • Fuel Injectors
  • Variable cam timing solenoids (VANOS, VTEC, VVT etc)
  • Idle air controllers
  • Nitrous solenoids
  • Boost controllers
VEMS features an advanced injector control system, which can control high impedence injectors with incredible precision. If you must run low impedence injectors and can not run ballast resistors, we do have an injector driver solution for lowZ injectors, but please contact us before ordering and ask about this. Coil drivers are built in and can be specified when purchasing a unit, up to 8 ignition coil drivers can be fitted, which can be configured to run single coils, wasted spark coil packs or Coil On Plugs. Because the coil control is built in VEMS has full control with coil charge/dwell times
  • 8: all 8 ignition channels are configured with built-in ignition driver controlling the ground of a coil. This is recommended for 8 cyl fully sequential (non-wasted-spark) ignition with traditional coils. Also popular for 5 cyl setups and 6cyl COP install.
  • 6+2: 6 IGBT + 2 logic-level : Suitable for up to 12cyl wasted spark, up to 6 cyl fully sequential ignition, while also suitable for the 4cyl active wasted spark modules
  • 4+4: 4 IGBT + 4 logic-level output
  • 2+6: 2 IGBT + 6 logic-level output
  • 0: 0 IGBT + 8 logic-level output (useful for 8cyl fully sequential with active coils)

Specify the engine model and any special wishes in the order comment. Examples:
  • BMW S50 or S52 dual-VANOS engine: VR, VR, VR + 4 * PFET high-side switches for the 4 hydraulic cam-actuator solenoids
  • BMW S54 dual-VANOS engine: VR, HALL, HALL + 4 * PFET high-side switches for the 4 hydraulic cam-actuator solenoids
  • "Preferrably leave 2 (or N...) custom (mcp3208) analog inputs without internal pullup resistor" (most analog inputs, by default, are equipped with internal pullup to +5V for installer convenience, but some sensors, like most pressure sensors are easier to install withOUT internal pullup).
