jono Posted July 30, 2017 Share Posted July 30, 2017 Wondering if anyone has monitored an ea82 EDI coolant temp device to see if is a simple rich or not rich switch for ecu or does it give variable ohm reads to ecu to vary fuel delivery? I want to use it as an egr switch just to operate at op temps Quote Link to comment Share on other sites More sharing options...
jono Posted July 30, 2017 Author Share Posted July 30, 2017 EFI not EDI !! Quote Link to comment Share on other sites More sharing options...
DaveT Posted July 30, 2017 Share Posted July 30, 2017 The cts is the 2 wire sensor that gives the ecu a temperature measurement. It is a thermally sensitive resistor. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 30, 2017 Share Posted July 30, 2017 It's a standard thermistor, not a switch. EGR is generally disabled by the computer till it reaches close to operating temp. What are you trying to do? GD Quote Link to comment Share on other sites More sharing options...
jono Posted August 4, 2017 Author Share Posted August 4, 2017 That.makes sense thanks. Fitting ea eighty two t into Brumby without ecu and any wet fuel delivery system. The ecu in donor was not controlling as per manual. It worked all temps all speeds yet all solenoids were good...ecu first found solenoid "stocked to open or shut" so that was fixed. I once had a frequency switch kit for speed control....gave up on idea. Just a temp range digital unit can take care this time.
