So today I picked up three 4 pin temp sensors at the local U-pull-it and I'm going back to the track this Sat. Since the sensor is grounded through it's wires and not it's case, I can just plug in a "dummy" sensor, wrap it in a bag, and leave it on top of the eng. Since the business end won't be submerged in water, it will automatically read lower---just what we want. And the gauge will be telling me what temp. the sensor is telling the EZL and LH ECU. |
Eric, that's a great idea, adding a "dummy" coolant temp sensor that's loose under the hood. One catch - the dash gauge reads from a totally different sensor. So you will never know what the "dummy" sensor is reading, without a digital scanner connected (which will show you the live data from the dummy sensor). That's good though, this way you know the exact engine temp based on the dash gauge.
Regardless, it should still work pretty well - and your tests back that up. I was going to try this myself, with a resistor pack, but I like your idea better since it's easier! Now I just need a 4-pin sensor...
