Description

The DTA S40 gives the best of both worlds for the high performance A-Series engine - a programmable distributorless ignition system that retains the simplicity of fueling with carburettors.

It will offer improved power and drivability once correctly mapped on a rolling road or dyno, for race or road applications.

DTA software is known for its user-friendly interface and is widely used by professional tuners.

We've teamed up with DTA to bring you a Mini-specific professional wiring loom to make installation simple. The loom comes with connections for the following:

  • Crank position sensor
  • Coil pack
  • MAP sensor
  • Throttle Position Sensor
  • Fused 12-volt ignition
  • Ground
  • Tacho
  • Shift light

The loom has been designed to fit the coil pack up on a Mini bulkhead, to plug straight into our crank position sensor kits and for the ECU to fit around the dashboard area. We would not recommend installing the ECU within the engine bay.

See the extra tabs for more info, wiring diagrams and downloads. For a complete installation setup, we also offer the MED Ignition Management Kit.

For owners of other A-Series powered cars we can supply alternative wiring looms - please contact us to special order.
