red80 New Member 12 Member For: 6y 9m 1d Posted 04/04/18 05:48 AM Share Posted 04/04/18 05:48 AM I'm running a BF turbo engine for an engine conversion and need to calibrate the coolant temp and oil temp to the Haltech ECU. Does anyone have the resistance charts for these? I.e. 0 deg = 10ohms - 80 deg = 0ohms or whatever it may be Link to comment Share on other sites More sharing options...

I seem to remember my wiring guy saying something about them being GM style sensors. Could be wrong though, as it was a while ago. 1 Link to comment Share on other sites More sharing options...

Eot is in the linked doc interesting the Cht is not listed. https://www.dropbox.com/s/dmw5g4n2yek2ir8/303-14 Powertrain Control Management.pdf?dl=0 Link to comment Share on other sites More sharing options...

The sensor doesnt touch liquid. Its head temperature.. Link to comment Share on other sites More sharing options...

Turbo Yoda sorted out the harness and they got it tuned at Castle Hill Performance. You could email any or all of these guys and I don't see why they wouldn't help you out. Of course you could just plot your own curves. Nothing that a multi-meter, a freezer and a pot of water on the stove wouldn't fix. Here is a discussion about that kind of stuff.

red80 New Member 12 Member For: 6y 9m 1d Posted 12/04/18 05:15 AM Author Share Posted 12/04/18 05:15 AM oil temp easy swapped if need be but head temp is a brand new sensor as they are a pain to get to if it fails Haltech use GM style sensors but by the time you buy a bunch of them they add up. Trying to spend money in the right areas without going overboard with new everything. Was going to plot the temps as suggested with a spare sensor and I figure the oil temp would give a good indication of engine temp. Does the Barra actually have a sensor for coolant?
