Good to see people using this. Anyone foresee long term issues with ABS and heat? I have been waiting to market these until I get my printer setup for polycarbonate, but maybe my worries are over blown? Glass transition temps are roughly 105 and 140 degrees C, respectively.

I've been using ABS parts around radiators for quite a while. Don't know if that's the same as something attached to the engine mass though.
Really cool design Sean! |

I have a grand total of about 30 minutes of run time on mine. 110+ ambient though. Doesnt even get really warm, but im not really heat soaking the engine bay, and I have all the intake/TB "coolant" (warmant?) lines removed and barbs plugged.

Here are some crappy photos of it the TPS bracket printed and installed. I repinned the TPS connector. Thanks again for designing this.

How did you repin the connector? I can't figure out how to get the pins out :( I'm using the same kia tps btw, and I swapped the 5v and sig wires at the ecu end with no improvement to my issue. In TunerStudio when I have closed throttle, my value is 165 and at WOT my value is 53, so I'm guessing the ground is swapped with another wire.

Why would you be repinning? The whole point is not to repin... Your ground is fine, swap the signal and 5v

Sounds like you sent 5v straight to ground then. Figuring out the pins is easy with a dmm.
|
Has anyone experienced an issue where regardless which way the red and green wires are connected, the throttle signal stays inverted? I had my TPS harness wires swapped for a while now without issue while running an FM VTPS kit, but now that the sensor has gone noisy i've replaced it with the Kia sensor and bracket to save a couple bucks. I've swapped the wires back and forth and just can't get it figured out, any ideas? 1990 short nose running ms2.

Yes, it isn't just them, the third one has to be switched too. Just try all the combinations until you get it right, that's what I had to do.

A knowledgeable moderator let me know that TS will let me calibrate it with the values being opposite regardless.. So for now the issue is fixed. Will go back due to OCD and try to figure it out in the future though.

Hmmm, ok. It didn't work like that for me when I was setting it up, but that was months ago.

Simply calibrate the TPS as normal, regardless of the higher value input being for no throttle and the low value being for full throttle.
google should get you some other details.. |
Im pretty sure all 3 iterations of my vtps were "backwards" and ive never had an issue afaik.
|
bought the TPS on ebay UK for a ridiculus 8 pounds shipped ( object 182634520178 ) printed the bracket at a local shop for 15 eur. bolted straight on! another thing to consider is that I've seen people having to take out the CF to be able to replace the TPS. in my case it was enough to pop the plastic cover of the OEM TPS, slide out the cover, then the TPS itself. reassembly: first the 3d printed bracket, then the tps, then screw everything in and JOB DONE. |
Wouldn't something like this be the easy button, instead of futzing with jewelers screwdrivers repinning or cutting the thing open to adjust internal connections?

Are you running a PNP?
|
No. Gonna be trying a Speeduino.
|
With speeduino you just need a small change in the code to pick inverted value. it should also be added in the gui at some point |
