I want to log fuel pressure with the Datalogit but I don't want to add more gauges. Is there a sender that I can by that has an analog output that I could wire into the Datalogit. I found a pressure sensor that outputs 0-20mV but I don't think that wil work. Any help would be greatly appreciated.

 

In my opinion this is an important tuning parameter that's woefully overlooked. I installed an AEM 30-2130-100 sensor in place of the Mazda fuel temperature sensor on the rail. the PFC's fuel temperature wiring works just fine and logs into the Datalogit as 0 to 5V. You will need to add the PFC's instrument ground to this sensor. Monitoring the pressure in comparison to AFR is enlightening.

You could probably just use the sender for a autometer electronic fuel pressure gauge, that's What I use and I think they are sold separate. It is a 1/8 npt, I have it screwed into the aeromotive fuel pressure regulator, the purple wire is the 0-5 volt output to connect to datalogit.

 

Thanks a lot guys! I will try Toms way because I don't have the wiring for the temp sensor so I will by an auto meter gauge and hook it up to FPR.
