ECUType / HONDATAKSERIESECU

HONDATA K–SERIES ECU

The Hondata K–Series ECU has software selectable 9600 bps or 115200 bps output baud rates. To be compatible with the Race Technology ECU decoder, the ECU must be set to output data at 9600 baud. There are two models of this ECU in common usage, the PRA and PRB. This unit will only work with the PRB ECU.

Name Race Technology Name Resolution
Engine Speed Engine RPM (RPM) 25 RPM
Coolant temp temperature 8 (Water temp) 0.1 oC
Air temp temperature 1 (Ambient Air Temperature) 0.1 oC
Battery Voltage misc 3 (Battery voltage) 0.01 V
Air Fuel Ratio misc 1 (Lambda 1) 0.01 lambda
Throttle Position aux 1 (Throttle position) 0.1%
Manifold pressure pressure 5 (Boost pressure) 0.1 kPa
Injector Time measured time 1 (Fuel Inj 1 PW on) µs
Ignition Timing angle 2 (Ignition angle) 0.5o


There is more information about connecting to the hondata ECU here:
http://www.hondata.com/help/kmanager/index.html

In particular the data output from the ECU is on Pin 24 on the E connector, this is labelled as “SEFMJ”


IMPORTANT: The Hondata ECU does not use standard serial data voltage levels, so the hardware of the Race technology ECU adapter must be modified to suit this adapter. A Hondata ECU adapter cannot be used with any other ECU, and visa-versa.

On the Race Technology ECU adaptor there is a 9-way d-type connector labelled ECU. You need to connect PIN2 to PIN E24 of the ECU.

If you are powering the ECU from a different power source as the ECU adaptor then you will also need to connect pin 5 from the ECU adaptor to the ECU’s power supply ground.
