TPS adjustment tool

[New To Sleds]

I'm seeking info; as a side job I make a tool that makes TPS adjustment a breeze and I'm curious if there's any need for this in the sled community. I ride dirt bikes myself and this is where the tool is currently being used, but I can easily make them for sleds if there's any need. You can see how the tool works here:

Please let me know if there's any interest in something like this among the sled community, any and all feedback is welcome. There's piles of discussion about how well this works in the dirt bike forums and there's no reason it wouldn't work just the same for sleds, assuming there's a need to ever adjust the sled TPS.

There is much talk on here about TPS, so I would assume there would be a good market.

There needs to be a 5 volt power source to the TPS so that the base setting can be adjusted properly.

Many threads on here about proper testing procedure.

The ECU gives you a nice tight 5V, that's why this works so easily. Here's a video showing exactly how it works. This is on a dirt bike, but I think you'll see how it would work almost exactly the same on a sled:

Works if you can turn on a key and get power to the TPS, not the case on our sleds unless they are running.....can't set base setting without aux power.

Just let it idle while you set it. Some dirt bikes are the same, if the engine is running then the ECU is giving 5V to the sensor.

Tell you what; if someone is genuinely interested and can send me pictures of the TPS plug, I'll hunt down the connectors and make a couple for them to try out for free.

Picture of TPS and plug. Initial base setting on the TPS procedure is with throttle plates in closed position, sled won't run. Can set idle voltage but that doesn't help setting the base starting position of the sensor.

Ahh, I see thanks for the clarification. I didn't realize you had to set the voltage with he throttle plate all the way closed, you don't have to do that on the dirt bikes. I wonder why the difference...

In any event, thanks for the picture of the plug. I'll try to find the plug, and I may be able to come up with a simple plug-in power supply to go with it. I considered doing this for setting the TPS on the bench but stopped because lack of need/demand, but if it's necessary for sleds then I'll get back on it.

If you have time, would you mind also posting a pick of the other plug as well?

Thanks!

Perfect thank you! I'll get hunting on the plugs and post back when I find them.

Piece of cake with powering up the ECU externally... SLP already makes an external power-up plug, then the rest is just back-probing the ECU.


The best thing id think for making available would be an easy way to back-probe the ECU. Most now use some fluke probes, or sharpened paperclips.

I dont think there is a market for another guy building pro or iq tps tool, there already is a thread in the iq section on how to build one also there are a few guys on here that build and sell them already and a guy on ebay,that is where i got mine 35 bucks free shipping,
