I’ve just completed sorting out some issues on a DTAFast S60 engine loom and the customer has a Stack 8100 dash.
Whoever wired it before had removed most of the sensor connections to the ECU so that they could be read on the display so the ECU couldn’t see the state of the oil or water temps and the fuel and oil pressures.
The guy I'm doing it for asked if I could wire them both but when I have tee’d them together, whilst they both see the readings but they are incorrect and they affect each other. By plugging each in individually, they work fine.
Having done many searches to see if I can find a solution, it seems others have had the same problem but no one has solved it. Have any of you guys managed to do this successfully? TIA
Unless the Stack 8100 can interface with the ECU (the MFD could do this), then you are best fitting two sensors. Otherwise, you could connect just the Stack signal wire, and create custom sensors to match the readings you get from the ECU.
resistance based sensors can not be split between two devices.
Your options are:
-Put in a sensor for each reading for each device (ECU and dash).
-Interface the ECU and dash through a serial or CANBUS connection, if they are capable of doing so.
-Connect sensors to the ECU and then use spare custom outputs to drive the dash inputs, if the ECU is capable of doing so.
