Re: Understanding your GenI Speedometer: Reed Switch
      10/13/04 02:21 PM

So I've been paging through my manual over the last few days trying to understand what the function of the reed switch is on the V6. Besides being a component of lighting our 4WD indicator light, under the section on Multi-Port Injection it lists the reed switch as having an input component of ignition timing! This set off a few bells in my mind although my cohorts assert that's it's probably not a critical factor at the worst. However...

Something that I'd like to share with the group today is what I've noticed about my fuel milage recently. With about 5000mi on the correctly rebuilt 3.0L V6, I've managed to sqeeze as much as 19.5mpg out of it at speeds of 55mph or under. Staying under 60mph, I can still get 17.5-18.5mpg. However, once I break that threshold of 60mph, my fuel mileage goes down to 15.5mpg. Oddly enough, after breaking that threashold, it doesn't seem to matter that much whether I'm traveling at 65mph or 85mph, I still get 15.5mpg!

Could this be the critical component where the reed switch input corresponds to better fuel mileage by correctly adjusting ignition timing?

Whatever the case may be, it's really got me anticipating expertimentation. 24 toothed speedo gear is in the mail and should be on next week. I hope to see a positive gain from the swap! (and maybe leaniency from the judge concerning that speeding ticket)
