Throttle Position Sensor for Carburetor

-
The holley is direct mount to a specific carb that already has the mounting holes, so you are paying $71 for just a gm tps and plug. The Innovate is best IMHO but you lose the choke linkage.

The innovate is the one I was considering. I’ve had good luck with their products. I do not have a choke or the linkage. It has all been taken off the carb I am planning to use, which is a 3310.

Also, I linked the wrong Holley kit I was referring to. Even though this one is made for a carb with a choke, it’s the one I meant to link.

I use the AccuLink kit with my Innovate SSI-4, has worked fine for years and calibrates easy.

Thanks for posting. What carb do you have it mounted on? Any pics?

I’m using a Quickfuel HR850 with the no choke body, but will work with either.

That looks well made, easy access to the adjustment screws at idle, and it is on the same axis as the butterfly versus a linkage, but I guess they all work well enough. :thumbsup:
 
I use innovate stuff, the SSI4, used a 350 Z throttle position sensor on the throttle pedal arm. Tells me what I wanted to know.

I like that. What do you use the data for? I need a 0-5 volt tps signal for a trans controller. Up until this point I’ve only considered the bolt on stuff for my Holley carb. I like that pedal setup.
 
I used it to see how quickly I’m able to roll into the throttle. I had no idea how long it was taking. You can daisy chain Innovate AFR gauge and their SSI-4 interface. It has 4? channels and you can create channels using math and other channel input. I’m logging throttle position/engine rpm/driveshaft rpm/G force/AFR using the SSI-4 and their AFR gauge. You may want to go with plug and play, just for the included conversion table. My throttle position sensor is not linear. I could create a conversion table to make it linear, but I don’t need it. Controlling a transmission might want a linear 0-5 volt output. My sensor being a rotating arm. The first 10% of movement increases voltage more than the last 10%. I didn’t buy any plug and play sensors. Have about $700 in the whole thing. Bought sensors from Amazon. The 350Z sensor is mounted to the pedal originally in the Z, it measures the position and the rate of open and closing. I just use the position terminals.

Awesome thank you. I’ve looked at the SSI-4 for data logging on carb’d stuff I’m just not quite there yet, and definitely not for the vehicle I’m doing this set up on. It would be overkill. But I am trying an electronic controller for a 46re and one of the things it needs is a linear 0-5 volt reference. So your rotary pedal set up (non linear) might not work. Appreciate the info.
 
I ordered the innovate unit from the link in post 1. Once I get it I’ll install it and update this post.

Just out of curiosity, what 46re controller will you be using?
 
For anyone following along, I received the TPS kit from Innovate and have it installed on the 3310 Holley I’ll be using initially to get the engine fired up. Fit and finish was great, and it seems it will function as designed. It’ll be a minute or ten until I put it in use but when I do I’ll let y’all know.
