I don't know what the variation is in resistance, but have you looked at thermocouple amps?

There are quad multiplexers out there that are used in the security arena. I'm pretty sure that Chasecam's multiplexer is based on them - though not sure. m One thing of note - I use a chasecam PDR1000. Nice unit and easy to setup. I have a 420 line Sony bulletcamera. At the "normal" setti...

It's in F and it's just the Ohm reading per temperature. It's up to you to figure out what the pull up resistor rating needs to be. I haven't had time to do that yet - working on a steering sensor first.

I think the OP wants to see if there is a GPS lock, not the logging status....

I just did some calibration work on some more VDO temp senders. The equation on the 120* is pretty good, not so much on the 200* one. It is a 400*F sensor and I can only get to 210*F boiling water. Assuming they behave the same, an exponential equation is best. 120*C Ohm = 1850.5e-0.0183(TempF) Temp...

You can pick up the tacho in a number of places: Connector X16, pin 20, it's the 26 pin white connector on the back of the instrument cluster, the black wire. D100 Data link Connector in the engine bay, pin 1, black wire Or any place between. (this information comes from the MCoupe wiring diagrams. ...

My firmware version is 8-5. Is there a compelling reason why I need to re-flash my DL1?

So, the dumb question of the day - All I do is run a wire from the battery + terminal to an analog in on the DL1 mk2?

Most cars run at 13.8-14 VDC so is that OK?

VDO temp Gauge/sensor + Pull Down to DL1

I am installing a DL1 and would like to use the VDO temp sensors with a pull down to the DL1 - the trick is I'd also like to use the same sensor to run the VDO Temp gauge.

Wondering if there are any issues with tapping off the sensor wire to the gauge for the pull downs to the DL1?
