Setting UP Hitachi Sera DBW

EMU BLACK / CLASSIC
1

Hello everyone,

I’m currently wiring an electronic throttle body (Hitachi SERA576) to an ECU Master Black (USB Type-C Edition)

The throttle motor is connected to H-Bridge 1, and I’ve tested the output—the throttle flaps do respond. The position sensor is wired to Analog Inputs 2 and 3.

However, I’m encountering an issue: the calibration tool isn’t working as expected. Unfortunately, the manual hasn’t been much help in resolving the problem.

I’ve attached two pictures and two videos that show the current setup and issue:

I’d greatly appreciate any guidance or suggestions to get it properly configured.

Thanks in advance for your support!

You have a CEL lamp on if there is a DBW error;, the DBW calibration tool won’t work

Hello Everyone

Hi Greg you were right. There was CEL on

CLT, IAT, DBW

I cleared CLT and IAT with a temporary resistor.

The DBW-CEL sometimes disappear, and the Calibration Tool starts.

It comes will the following Error Message “Max pos is not equal 100%. Something went wrong!”

I attached the details in the link below.
I would be grateful if you can help me in this final step.

Note: When I finish fix this issue, I will make a complete Step-by-Step guide. Such that it can help others.

Hello Everyone,

I’ve successfully got everything working, and I’d like to share the steps I followed based on my personal experience. I hope this helps others who are setting up DBW (Drive-By-Wire).

STEP 1: Hardware

I chose a compatible throttle body from the DBW Wizard options.
During my research, I discovered that some electronic throttles require more than 6A of current. The DBW Wizard dropdown only includes throttles that draw less than 6A.

In my case, I used a Hitachi SERA576, which required no physical modifications.

Once you have your throttle body and its connector, look up the pinout diagram online. Then wire it according to this diagram:

STEP 2: Wiring & Testing

  1. Wire the throttle as shown in the link above.
  2. Once wiring is complete, check if the throttle flap responds:
    Go to Tools > Test Outputs > H-Bridge1A, then **H-Bridge1B.
  3. Next, you need to determine the throttle position range:
    Go to Log > Analog Inputs and monitor the reading for your input pin (in my case, B17).
    Record the value with the throttle fully closed – this is your “Position Min.”
    Use your finger to open the throttle fully, then record that value – this is your “Position Max.”

STEP 3: Parameter Setup

In the software:

  • :white_check_mark: Check the “Enable” box.
  • Enter the Min and Max values you recorded.
  • Set “Position Sensor Input” to Analog Input #3 (B17) (or your corresponding input).

STEP 4: DBW Calibration Tool

Before starting calibration:

Ensure there are no CEL (Check Engine Light) alarms.

You can now proceed with the DBW Calibration Tool.

Hope this helps and good luck with your setup!
