It is. FAST offers an optional harness for analog input of up to 8 additional channels to monitor pressures, speeds, temps, etc. I am using 2 of those for oil pressure & fuel pressure, which work fine using inexpensive transducers from E-Bay.. You can also use them for D/S speed, accelerometers, etc. Although the instructions state oil temp is a useful input, FAST doesn't offer a sensor, nor can I find one available. My 1st thought was to use another CTS, which FAST told me should work fine. So I installed one into my pan. I then realized it is only a 2 wire sensor, and won't communicate with the ECU, which requires a 3 wire sensor. FAST now told me they thought a 97-98 Vette uses a 3 wire oil temp sensor. From what I've found, they are all 2 wire, the same as the CTS I already have. Now, I'm stuck.
