No, that sensor measures the position and the rate the throttle is moving. I figured out which pins showed variable resistance when moving the arm and used them. Most sensors use 0-5 volts. When logging data you configure the channel so the range of data you display relates to the 0-5 volt range. You tell the logger that zero volts equals zero throttle and 5 volts equals full throttle and it displays the valve throughout the range.

Got it.

Can't use that setup in my Coupe - totally different pedal arrangement, however the sensor tab is something that maybe more usable in terms of hooking this up to the existing Carter TQ carburetor linkage...so yeah, good stuff, thank you again!

Diplomat, if you figure how to hook to a thermoquad, please let me know. I don’t know if it would be better for me on pedal or carb.

I'm using a carb.The diagram list FI,or carb....I'm looking to upgrade to one of the 5.0 Pumps. I currently have the A-1000.

Ran this setup for a few years with a LM-2

I also ran 2 O2 sensors and a map sensor all connected to the LN-2 for data logging.

So here is a strange, but I think nearly OEM solution for the Carter TQ crowd out there - Mopar stuck the "Throttle Position Transducer" (TPT) on the TQs that were installed in cars running ESA (Electronic Spark Advance), LeanBurn, etc. setups. The Carter specs book says these things were used to provide up to 15 deg. advance at WOT (once the transducer readings were accounted for by the computer). The only other specs about the transducer itself that I have been able to find is that the coil itself should have been 60 and 90 ohm reading.

Hmm...OK, so what's next?

Well, not paying attention to any of this "way back when" I yanked so many of these things off the carb and straight into the garbage bin as the LeanBurn stuff was getting converted that I lost count. Yet today I could certainly use a working one because I'm guessing this is a simple resistance measurement and therefore if you were to supply input voltage and read the output (the TPT just has two terminals) you could develop a reading map that basically spells out the actual throttle opening angle...ta da, equivalent of modern day TPS after all. All you do then is to bring those values into your data logger and start logging.

Spring is nearly here, and my bucket of TQs has got to have one of these things still attached...somewhere...I hope... boogie

Look up 2016 Challenger or other accelerator pedal
All the new cars have the TPS built into the pedal. Feed it 5V and you have the TPS signal.
I'm sure you could pick up something cheap at JK and bolt it in.

Diplomat - yes , let me know what you figure out.

BDW - will check the gas pedal idea out. If you don’t have to use the new pedal, that would be good. Otherwise, I don’t think I would want to use a new pedal. I was trying to keep the car look as stock as possible and I already are needing to use the new console (had to modify the hump for the bigger trans.).
