Serial data out (rs232) for a dashboard

[kamannolli]

I want to connect a dashboard "DashII" from Race Technology/ UK to my Kpro ecu (Civic Si ´05) by using a rs232 interface. Therefor i need to know, which of the ecu´s pins (on connector "E") delivers the serial data stream?

In Kmanager, go to Help, contents and search for serial output. All the information on the serial output is located there.

Thank you for quick response. I followed all instructions for the serial output like described in KManager Help. Also i set the baudrate to 9.600 as indicated by the instructions of Race Technology. Then I connected the Race Technology interface for Hondata with the ECU. To find out if there is a serial data steam, i used the programm "Lite Monitor" from Race Rechnology. But it is not receiving any data. Is there a possibility to find out, if there is a serial data stream directly on Pin 24 of connector E before connecting it to the interface? What is about the program which created the diagrams under the point "serial otput"?

The dash2/dash3 cannot read the ECU serial stream directly. I believe Race Technology sells a box which translates the serial output from the ECU output, but I am unsure if that works on the dash2.

I am using this box, it is the serial interface sepecified for Hondata. The program "Lite Monitor" from Race Technology does not show any receive of serial data from the interface. So my question means: How can I find out if there is a serial data output directly from the ECU? If there is one, the fault should be founded in the interface or connection of it.

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.

I have not used the interface from Race Technology.

I suggest using a logic probe (~$10) to see if there is serial output from the ECU, then from the RT box.

Serial Output

The K-Series ECU can be configured to output a serial stream for a datalogger.

Note that only PRB calibrations support the serial ouput. PRB calibrations may be used in PNF, PRD, PRC and PND ECUs with re-tuning, but cannot be used in PRA ECUs.

Are you using a PRA ECU ? Im interetsed to know as Im trying to find out if the Race Technogy Interface works with the PRA .. but no one seems to know ..

However .. the data is available to the Hondata software so why would a "box" not be able to take that data from the ECU vai the USB and then give it to a serial output ?

[Hondata]

Good point - the PRA ECU does not have a serial output. The reason why the PRA does not have the serial output like the PRB is that the PRA flash memory is 99.9% full, and there is no room to add any extra features.

The Race Technology box translates the ECU output to that which the DL1/Dash can understand.

Its a pity RT cannot get the data from the USB port, like the Hondata software does - that would be nice to just connect a USB and have a lead that then connected to the serial input on the DL1.
