The TPS adjustment thread


Recommended Posts

I have adjusted the tps opened up the exhaust and removed the smog parts. The bike runs really good now so the question of the day is, should I load the European map or leave it as is?

IMO, adjusting the TPS, removing the smog, and opening up the exhaust makes the bike run good.....the Euro map makes it run great!

Euro map installed, wow what a difference! smooth linear power, more responsive, way more bottom end power. TPS still at .67 and I think I will leave it there.

Shocked you found someone in CA to change it.... I am looking for someone to do it for me. Can you PM the info on where to have this done?

It's an active sensor, it has to be powered to give a reading. The easiest way is to use the power supplied by the bikes ecu. The challenge is getting to the wires to take a measurement while it is powered by the ecu, because the connectors are water tight and there's no access. The TPS tool allows you to access the wires to take a reading while the ecu is powering the sensor.

Watch the video at www.tpstool.com and you will see how it works

To clarify; making holes by forcing the probes into the wires or the plug will in the least create a hole where water can get in and allow corrosion to start. So poking holes in the wires or the plug might work to get a reading, but could lead to long term problems when water gets in and the wires or plug start corroding. With the tool you don't have to poke any holes.

I'm curious if people are setting and forgetting their TPS or if they are altering their summer, high altitude, hot temp configuration to go to a winter, low altitude, cold temp configuration. My 14 350XCF-W still isn't broken in, so I haven't really experimented with it yet.

In theory you can set and forget since the ECU does adjust for altitude and temperature.  But it is an open loop system on the USA models, so depending on how perfect KTM got the maps, it is possible that tweaking could help with drastic changes in temp or altitude.  I'm curious to know too, anyone try tweaking the TPS when altitude or temps change drastically?  I'm in FL myself, high altitude is about 100' and temps get all the way down to about 55F for a couple days over winter, so my testing grounds aren't the best for this particular question. 😉

Did a test ride......the low rpm farting is gone...but I did have my first flame out going from 3rd to 2nd gear. No biggie just pulled the clutch and bump started it back to life while it was rolling. Gonna try .62 now and see what that does.

Desmogged and screen pulled...14 exc 500..stock map

You may want to go with .64, that's what worked for me at least.

Any special process or care that needs to be taken to clean the injector?  I haven't looked at it or done it before so I appologize if that is a stupid question...

 

remove.. go here www.proflowtech.com , print out the service request form, fill out, box up , ship 🙂 We basically loose money on cleaning 1 injector, but do it anyway in hopes people will send sets from bikes, boats or vehicles later and spread the word. Ktm kehien injectors are literally the ONLY dirt bike injectors we see issues with.

Greg,

What difference are you seeing with KTM injectors vs. other makes? Why do you think KTM has more issues?

What was your stock setting? I was surprised to see mine @ .56. The bike ran good at .62..... But I did have a couple of backfires. Have you tried above .64? Or did you just work your way up to that point to find your sweet spot?

Thanks
