Nautamaran
2004 140” HRC 2500 (Crewed)
Last winter forum member Calbiker and I spent a fair chunk of time reverse engineering the data available from the engine and transmission modules from the OBDII port. He used the information to make a data logger, and I made myself a dash display.
The top row shows true (calibrated) vehicle speed, fuel consumption rate (Litres per hour, or per 100km), LOD, and fuel remaining in the tank (64 litres).
The middle shows engine coolant, ATF, and engine oil sump temperatures, fuel quantity control valve duty, rail pressure, and rail pressure control valve duty, return fuel temperature, oil level, and oil quality.
Next are actual and selected gear, engine and input shaft RPMs, TC Slip, engine torque, input shaft torque.
Bottom section shows LOD, MAF, turbo actuator duty, and EGR duty, and ambient, intake, and MAP air pressures, and intake air temperature.
The display has a touch screen, and this winter I intend to write a bit more code to allow pulling and clearing DTC's from the engine and transmission by tapping areas of the display. It's able to read basic DTC's and their status (eg: P1041, current/pending/stored), but I will have to do some additional snooping to get at the extended sub-codes (eg: P1041-3)
This week I presented one of these to Glasseye, and he encouraged me to share the love and offer them for sale to forum members, something I was holding off doing pending some additional beta testing... but I've been running it full time without a glitch all summer and it seems that the hardware is stable enough.
So... who would be interested in buying one of these if I were to put a batch together, and at what price point?
