Megasquirters using 32*i coolant sensor, need your values..

[beast02er]

I am trying to configure my coolant sensor and am having an ass of a time getting the readings that I think make sense. I had 36 at 38 degrees F, then 70 at 150 degrees F, and then I measured at 100 degrees and got 36 again, this didn't seem right.....

Do any of you have your values handy? I found one of the guys on the board, and his #'s were like .3 etc..... and that confused me because the megasquirt site was showing the GM values to be big whole numbers...

So if you can help me out that would be great.

Which sensor are you using? Is it the standard sensor which goes into the coolant neck of an E30? What color is the plastic connector on the top (assuming it's a Bosch)?

[beast02er]

Yes, its the standard coolant sensor from the E30 water pipe thingamabob. Top is brown I believe.

Okay, that's the same one I'm running. I have my values written down at home and I can send them to you this evening. However, I think the most important thing is that your numbers are calibrated to YOUR sensor, and that they read consistently. If you are getting inconsistent numbers, you may want to double check not only your multi-meter, but also maybe try getting another sensor, they're cheap at Pick'nPull

I use the Bosch defaults and they seem to work well. They are:

-18 = 12000 ohms

18 = 2315 ohms

94 = 250 ohms

All degrees in Celsius.

Cool, thanks inka. I will try those values out and see how it likes them.

I got the following resistance number, all are in degrees Farenheit.

35 degrees...5500

84 degrees...1700

208 degrees...230

On the low end it's reading perfectly, but on the high end it's a few degrees out so I need to adjust the number a bit. Good luck.
