Honda-Gen-PGM-FI-Modbus

Adapter to gain access to Honda Gen DLC data via Modbus TCP.

The current master branch of this project only offers up mock values and does not query the actual hardware interface. This project is still in development.

See my other related projects for more context.

Modbus Table

The values are broken up into their respective underlying controllers. These numbers are 0-indexed. If your Modbus client is 1-indexed. Add 1 to the addresses. All values are unsigned unless noted.

ECU1

Address	Description	Example	Notes
100	Runtime in Days	42
101	Runtime in Hours	59
102	Runtime in Minutes	30
103	Engine RPM	3000
104	Battery voltage * 10	124	Divide by 10 to get 12.4v for example
105	Cylinder Head Temperature in C	50	This is a signed integer
106	Ignition Degrees	65526	Signed integer, -10 for example
107	Output Voltage	120

ECU2

Address	Description	Example	Notes
110	Baro Pressure in KPA	100
