• KiwiEFI K88 ECU

The KiwiEFI K88 is a high speed 32bit Teensy 3.5 powered Ecu with 8 x 8 sequential fuel and ignition, with Can bus communications,

The K88 uses the same Teensy pin assignments as the Speeduino Dropbear ECU and is 100% compatible in software configuration so is able to utilize all current and future firmware upgrades written for the Dropbear.

* Includes Mating Harness Connector and Terminals

  • A 56-pin connector which allows the simultaneous use of stepper idle control and eight other digital outputs,  (i.e. you don't lose 4x outputs if you require stepper idle control.)

  • Serial output to the Ecu connector which can be switched between 3.3V Logic level or RS232 level for connecting external devices.

  • Socket for a Crank/Cam VR conditioner allowing use of MAX or other types of conditioners from KiwiEFI and other vendors. With switch selectable filtering.

  • Socket for a 2nd VR conditioner on Digital input 1&2 pins for VVT cams, Wheel speed sensors, Vehicle Speed sensors etc.  With switch selectable filtering.

K88 Features

  1. 8x high impedance injector drivers (with diagnostic indicator LEDs)

  2. 8x 5v/12v coil pre-drivers for use with igniters/smart coils (with diagnostic indicator LEDs)

  3. 8x Digital Outputs:  (as well as 4 dedicated stepper motor outputs)

    2x low current outputs for Tach and FP relay control.

    4x medium current outputs for Fan relay, Boost control, IDL1, and Idl2.

    2x high current outputs for VVT1 and VVT2.

    Stepper idle control uses optional DRV8825 board

  4. diagnostic indicator LEDs on the Fuelpump and Tach outputs

  5. 7x analog inputs plus internal Barometric Pressure Sensor and Battery Voltage sense inputs

  6. 4x digital inputs

  7. CAN BUS transceiver with termination jumper select

  8. Serial Data with switch selectable 3.3V Logic level or RS232 voltage levels

  9. Serial data TX indicator LED

  10. Optional plug-in VR conditioner for Cam/Crank sensors

  11. Optional plug-in VR conditioner for DI1 & DI2 inputs.

  12. Switch selectable filtering on Crank/Cam inputs

  13. Switch selectable filtering on DI1/DI2 inputs for filtering sensors such as VVT, Vss, Wheel Speed etc.

  14. Diagnostic LEDs for Crank/Cam and DI1/DI2 inputs

  15. Optional internal Map sensor or external sensor (we recommend external for faster response), see accessories page for Map option.

  16. 4x LED indicators for power supply voltages status.


We do not own Speeduino, we make ECUs to run the Speeduino firmware to help users who wish to get involved with Speeduino who may not wish to build their own ecu.

Speeduino is a standalone open source ECU project aimed at the DIY type person who would usually install and tune it themselves, giving an extremely cost effective way to run their engine.


Please keep in mind that being an open source project you will need some diy skills to use it.  If you are looking for a polished product, to have professionally installed and tuned, with strong dedicated support, you may wish to consider other options.
