Transmission Temperature ECU Input

[Trackman]

I'm considering using the Auto Meter 2252. Does anyone have a part number or link to the pigtail I need for it? Auto Meter offers a harness, but it's more than the sensor!

The Delphi Metri-Pack mating connector & terminal is in post #1 of this thread.

Danny, I'm looking at using the Auto Meter 2253. They list only 8 temp/Ohms settings (LINK). You think we could do the "math" to make up the rest of it for the Holley EFI 16 Cell Calibration Table?

Plotting it out in Excel, it looks like the curve on the right:


I would input the values given and leave some columns blank in the area where you would want the most resolution, which is presumably in the normal operating range, then just add values that make it a smooth curve. Andrew

I excluded the 350°F temperature cell, and included the 198°F & 213°F cells. I also added this sensor calibration data to post #1 of this forum thread.

Temperature = Ohms (Holley EFI 16 Cell Calibration Table):
60°F = 1200Ω (Right)
80°F = 827Ω
100°F = 453Ω
130°F = 292Ω
160°F = 130Ω
175°F = 103Ω
190°F = 76Ω
198°F = 69Ω
205°F = 62Ω
213°F = 55Ω
220°F = 47Ω
230°F = 41Ω
240°F = 34Ω
260°F = 27Ω
280°F = 19Ω
315°F = 14Ω (Left)
