SECU-3 Micro Configure GAS_V as O/P

Post by jim-bartlett »

Hi. I'm in the process (finally) in configuring the SECU-3 Micro to drive my 1968 Morris 1310cc 4cyl Mini ignition. I will be using:

1. A Hall effect TPS -> CARB
2. A GM temp sensor -> TEMP
3. 1 wasted spark coil (VAG logic level, so will be driven directly from SECU-3 Micro -> IGN_OUT1 & IGN_OUT2
4. 1 VR CKP sensor using a 36-1 sensor wheel -> CKPS1 & CKPS2
5. GM 1Bar MAP Sensor -> MAP_S

My question is, can the GAS_V be configured as an O/P? I want to use it as an O/P to drive a solid state relay for my electric radiator fan.

Hi,
GAS_V is input, not output. Because, two existing outputs are already busy, the only way to control a relay is to add several components (transistor, two resistors and diode) and connect them to the one of MCU ports.
