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...

You know, it's a funny thing, I left the dummy sensor on today---just for grins---Went to church, also went to a couple of stores, and I keep wondering why the gauge was reading so high. So we have one sensor for the fans, one for the LH and EZL, and a third one too? Where is it? This means I didn't really know what temp. was being sent to the LH and EZL?
What I'd like to do on the street is let the LH see actual eng. temp. (for good fuel economy) and let the EZL see only what I want it to see via a resistor (which should help both fuel economy and power---the EZL is way too prone to pull ign. advance at the slightest little rise in temp). I just don't know which pins go where.
I can't wait till you start trying this stuff on your E420. Just make sure you've got plenty of rubber under that thing! Regards, Eric
