Orion is the low cost Engine Control Unit (ECU) or Transmission Control Unit (TCU) which replace the whole of our economy range products. With slight changes in some harnesses it is backwards compatible with all the ECU range products. It has negative, positive and coil drivers to cover most applications and reduce costs. It can connect to most sensors found on engines and transmissions. The biggest advantage is that it has a bootloader and firmware can be downloaded with the tuning cable. No special firmware programmer is required.
