Pete_89t2 Posted April 20, 2020 Report Share Posted April 20, 2020 I'm building out a new wiring harness for an FD RX7 project that is running a G4+ Fury that has a Continental flex fuel sensor. According to the Link help file wiring diagram for this brand of sensor, it says to connect the sensor's ground pin to the "Ground Out" (green wire on the "A" connector if I were to use the Link wiring loom). The previous owner simply grounded this sensor pin to the engine block. Does it make a difference? The sensor seemed to be working fine in that configuration, as I was seeing good data from the sensor in the logs. Thanks, Pete Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 20, 2020 Report Share Posted April 20, 2020 Yes that should be fine. It is a digital signal so not too sensitive to ground offsets. The switching threshold on the DI's is about 1V, so as long as there is less than 1V offset between ECU ground and Engine ground (highly unlikely) it will be happy.
