TPS censors for carbs.

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

My bet is it needs a tps bolted to the linkage. Probably a GM sensor. The three wires are 5 volt feed, reference,and ground. This way the pump will increase volume with throttle opening. Also assuming fuel pressure should be set with the throttle lever at wot.

Thxs Doug Been researching this and found out that Holley actually sells a TPS for the 4500 series carbs. Reading though some of the commits on the tube someone mentioned DWM any ideal what that stands for?

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.

Edit: 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.

I've been eyeballing these for a long time since for my DIY carb tuning efforts this would be a great data point to have.

What I've learned so far is this: while the well known aftermarket vendors for the most part can provide you with a nearly "bolt-on" setup, unless you have to do so I would recommend eBag shopping...most of these sensors are pretty generic and they can be had for literally $10-15...so if you have to make your own mounting brackets it just makes sense to save a boat-load of cash in taking that approach.

Search eBay for the following item ID 156108911635, it literally appears to be the very same switch: 'GM part # 17112679 TPS'.

Yes I do...I have one of the newer Holley Dom's that has provisions for one and I wired it into my stand alone dash. Works well, and I trigger the data logger off of it at 80% throttle...

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!!!

I would like to see this as well! Does it matter what year 350z tps?

Let me look for pictures of it installed.

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

The green trace is it, it is not linear, but it showed me what I wanted to know. You could build a compensation thing in your channel configuration.

Did you have to do any figuring for the amount of peddle arc to open the tps all the way vs. the peddle all the way to the floor? Or did full peddle equal full opening of the tps?

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.

I m not familiar with logging software, I assume the computer that needs the TPS input is where you could do the setting for it? I will be using a TPS for a 8 speed trans install so I assume that the controller will be where that would be done?

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?

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.

Thxs a key part in this is a micro switch.

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.

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.

Thank you.

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...

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.).
