Quote: Thanks for the recipe Gunpilot. That is helpful. Emsvital was suggesting I calibrate it while the engine was running so the voltage at calibration was the same as with the engine running. That kind of changes things a bit, I was wondering what his take on this would be.
Oh, I see. Well, there may be some merit to that but I've always done mine with the engine off, and like as not, with a somewhat depleted battery from all the cranking and messing around. You could put a charger on it instead of running it but I guess even that would be different. Sam My first O2 setup was a narrowband with an Autometer gauge, and it was crazy sensitive to chassis voltage. I could change my AFR reading by turning the headlights on and off. The LC-1s have not been that way for me. |

I'm not sure how clean the power from a charger would be....... Go thru the steps to calibrate (sensor not installed) as indicated. My idea was to have the car running for the higher voltage. I'd still try that. Also, there's a setup parameter that changes the response time from immediate to a slower update (I'm thinking 1/12 sec). This is supposed to help with an E8. You do this with the LM programmer.... |

So would you start the engine for all power up steps? Sam |

Got caught up in church activities with Easter week. Would it be helpful to put a voltage regulator in the 12 volt supply to the sensor and control module,(LC-1). I drove it to work on Thursday, and everything worked great with no error codes. But, it was a little cooler on Thursday. Sam |

You may want to try a capacitor to smooth out any voltage spikes you may have from your cars charging system. Find a good quality 25 Volt (or more) of around 10 mfd value. Wire it from ground (-) to the +12 volt line that powers your controller/cpu-what ever it is. As close as you can to the controller/cpu/what ever. You can try a Radio Shack part but I would not-most of their parts are not rated for the temp under the hood. |

What would be a good source of high temp capacitors? Sam |

Were do you live? Most any electronics/TV repair shop will have them. It just Radio Shack is not the best place to get parts. |

Thanks Chuck, What is the logic governing the choice of spec for the capacitor? Keep in mind I have only the vaguest notion of what a capacitor does. Is a 1000mF part better, or as good, or worse in some way? I looked at the assortment at Radio Shack, and the 1000 mF part is about the same size as the old capacitors that used to be in the distributor. Would a distributor capacitor work? Is the spec critical? Sam |

The value of a capacitor is not critical (in the 1930's a +/- of 80% was common) but they do have a range. 10mfd is good for short spikes. A 1000mfd is good for audio-filter out "hum" or coupling low freq audio from stage to stage. .001 mfd is good for rf filtering/coupling. A "cap" is like a short term battery as it soaks up voltage and gives it back slower. |

I wouldn't say that the value was not critical back then, but as for today, what he said! |

OK. A 10 MFD it is. You don't have to educate me completely here,(there would be a serious limit to the potential on this end), but as a matter of curiosity, and something I have always wondered about, why does a capacitor NOT create a short. It does go from ground to +12. Thanks in advance for any education you do provide. Sam |

Caps can make a short-when they fail. Do you know how a resistor works? A cap acts the same but only for AC voltage. It blocks DC and passes AC. A "voltage spike" can be thought of as AC because it is a short pulse. A cap passes the AC to ground (shorts it)-Not really but it can be thought of that way. |
