Assembled, cased VEMS v4
VEMS ECU with internal DBW (electronic throttle), software configurable input triggers, and multiple communication interfaces, including internal CAN bus interfaces.
VEMS v3 assembled ECU is recommended for now, except very special installs.
For CAN-dash, there might be a more cost efficient approach, please detail your app on your project page and see CAN-bus page.

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.
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)
Flyback:
- "active flyback" is a must for low-Z injectors (universal: can be used for high-Z too)
- or "High-Z only 30V flyback" for high-Z injectors only.
- Low-Voltage is obsolete (not recommended, except for those who know exactly what they are doing, or replacement of old ECU with similar option if re-tuning VE is not an option.
Specify the engine model (which does not, by itself, make it a "special request", and it is non-binding; but allows some chance of catching mis-specification early).
NOTE: The generic/universal harness for v3 is not applicable. Requires detailed project page, with all information suitable for testing (eg. trigger patterns). Leadtime unspecified. expect appr 2 months. Service=ASAP is not applicable.
