I have my four individual EGT sensors wired up to sensor ground and precision 123 and four range of sensing is about 30deg, Is there a setting I’m not seeing wondering if it’s set to 0-5v? and it ranges between 90 and 120. If I hook individual sensors to my fluke meter sensors measure correctly. Any help would be appreciated. Thanks
Sorry, but your description is not clear to me.
- Are you using PRO-8 or PRO-16?
- What do you mean by “range of sensing is about 30deg”?
- “and it ranges between 90 and 120” - Do you measure 90-120 degrees with EMU PRO in ambient air?
- Do you have other sensors connected to that sensor ground?
From ambient to the car running raise about 30deg, I’m pretty sure I used a dedicated sensor ground but shared for all 4 EGT sensors
It is the Pro 8 ECU, is there a setting from 0-5v or MA?
There are no settings to change the measurement range.
For now, it is 0-256 mV.
The only settings you can change are measurement mode and pull resistor. Measurement mode should be set to single-ended, which is the default. You can change this in “ECU / Hardware / Precision analog”. The pull resistor should be set at 1M.
Those sensors also have polarity, so they won’t work if connected the wrong way around.
