Anybody here run them? I'm looking to upgrade a fuel system with the Aeromotive 5.0 brushless variable speed pump, it come with a 3-wire hookup. The third wire is for a throttle body censor. My question how does the carb censor gets wired? I'm using a MSD digital 6 for now but will be upgrading to a 7.....Thx

We run them on our Off Road Truck Racing Series engines that require carbs. However, we use all Motec electronics and software. It is a RG.SN.3051 part # if this TPS will work for you.

The Gen 3 Ultra Dominators have the provision for a TPS. We use it for a Racepak, no reason why it couldn't be used on other carbs with a little fab work / or modification. https://documents.holley.com/199r10624rev.pdfEdit: Looking at the instructions I'd be tempted to run it with a micro switch for full demand when the throttle is opened to a % position of your choice. It looks like it needs a 0 - 5 V signal to get the full variable speed mode, but anything over 3.7V's it runs at full speed anyway. https://prod-da.s3.us-east-2.amazonaws.com/BHKJ/07742b772ad557f0b01ab640e6a80905.pdf

I bought a throttle position sensor for a 350Z and mounted it to the stock pedal. The stock arm of the pedal rotates the sensor. $35? This is an A body WWHHHAAAATTTTT???? That's excellent setup...pics please!!!

Here it is. Been on the car for a couple of years?

Did it through the logging software. Watched what volt value it showed at idle and watched what it showed at full throttle. Then made those voltages o% and 100%. Some will just self learn.

Let me look for pictures of it installed. Thxs for the info. ? those pictures you posted on the TPS is six wire/pins and most of the one i see are the three wire .Do you wire in all six of them into your system?

My question how does the carb censor gets wired? I'm using a MSD digital 6 for now but will be upgrading to a 7.....Thx OK. As far as I can tell the pump achieves full speed (100%) @ 3.7V and min speed (25%) @ 0.5V which means it has a resolution of 25- 100% speed in 3.2 V. You will need a 5V supply to achieve the best control. Otherwise, if you will be using a 12v supply, aprox only 25% of full TPs movement will give you 25 to 100% speed control and it's likely to be nearer 20% movement once the alternator is running. So pretty much like an on/off switch anyway. If you just require the TPS to control the pump you can't get much easier than what Aeromotive recommend using a simple micro switch. Again the "on" (100% speed position) can be set to wherever you feel comfortable with throttle wise.

Are you using a 5.0 pump ? it's listed as FI only ? If you are going FI it's a different ball game entirely.

Thxs for the info. ? those pictures you posted on the TPS is six wire/pins and most of the one i see are the three wire .Do you wire in all six of them into your system? 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.

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. 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...
