Zeitronix Eca Wiring And Config

[Hanaldo]

Precisely

Though getting the sensor into the ethanol is going to be tricky, seeing it's all wired into place now. Really should have tested it before installing

I have a long shot for you haha I noticed in the install instructions it says any air bubbles will cause incorrect readings.

Any chance you've got an air bubble in there giving inconsistencies haha?

So I did a few tests over the last few days to test the accuracy of my sensor.

First of all my sister is a lab technician at ChemCentre which is WA's statutory body for analytical tests. So I gave her a sample of E85 from my local station and she tested that using separation funnels to be 88%. Accurate to within 2%. Then using a sample of the same batch of E85, my sensor gave me a reading of 82% on both the Zeitronix display and my ECU.

Then using a multimeter to measure Kelvin resistance, I measured that sample of E85 to be 13 degrees. My Zeitronix display told me it was 12° while my ECU says 17°.

So, I'm still not sure what to make of it...

Does it matter how accurate the sensor is if it's dyno tuned on that same sensor? Just stick it in and tune the damn thing.

[Hanaldo]

Matters to me!

It will be getting tuned. I just like to know that what I've done is working correctly before I give it to my tuner.

I understand that, but the ecu doesn't care for exact content percentages, as long as the sensor reads consistently it will tune fine.
