HI all,
I can't seem to figure out how these two features work - in normal ECU operation the fan will switch on its output when the CLT temp reaches a predefined temp, and then outside of the hysteresis it will switch off the output again --
The fuel pump should switch on as soon as ignition is switched on and power is applied to the board - go through its prime cycle (how many seconds preset in the tender studio software) and then switch off, until the engine is cranked, then it should switch back on again and stay on until ignition is switched off again.
I cannot seem to get any joy out of either of Pin14 and Pin15 -- I have tried to connect a relay shield to the mix and use the pin14 and 15 as the GND pin - no luck, i tired to use it as the SIGNAL pin - no luck either....
is there possibly a diagram available?
