I will get the oil temp data by taking the vdo oil temp sender (thermister) in the sump location and remove the thermister and modify it for a thermocouple (thermowell).
I can drive the oil temp gauge with a D/A converter as well as the CHT gauge by modifying my program to feed the signal from the highest cht of the 4 to the cht gauge so it will always read the highest temp from the 4 cht thermocouples.
I'm not worried at all about oil temp right now because my cooler/ducting system never goes over 200F while driving at extended rpms for a long amount of time.
