FE/FC 2015 FE 350 TPS settings

Just bought new FE 350 does anyone know best TPS settings for this bike?

S or non S? If S best to leave the TPS alone from what ZipTy has discovered.

non S

I bumped my 501 up to .60 and it's perfect IMO. Not sure about a 350 but it's been said to leave it where the factory sets it. I don't ever need to use the cold start button even when its 30 f outside. Fires right up. I have the Euro reflash and the sicass map switch installed as well. Highly recommend a reflash.

Where can I find more info about that? My FE350S pops and buckfarts on decel like crazy.

Call zipty. They have a power commander solution.

Dont know about the 350, but I just recently got my 500exc running right with a TPS adjust (to .638v) and some decent settings on the tuner (richened low, leaned mid/top). Zero pop, no hint of flameout and runs quite a bit cooler. None of which it did w/ stock TPS and JD recommended tuner specs. The tuner isn't cheap, but it along with the tps tool ($35) made my 500 like it should have. My bike is uncorked and desmogged, btw.

The Powercommander on the FE350s performs beautifully and there is much power to be gained even off of the dyno. Testing the newly tuned 350S showed smooth power, except when the throttle was snatched open hard from 0%. Power was inconsistent and was causing occasional flame outs. I like having quick response for lofting the front wheel over a log or rock and I hate having to time the power delivery for a sudden ditch or drop off. The Powercommander offers an amazing accelerator pump feature to relieve this. It's going to be a "work in progress", but for now the 350S is feeling much snappier off the bottom and will definitely feel more controllable in the slow technicals.

Hey Tinken,
You have a dyno chart for the 501 before and after the PC?
I'm on an S model and, based primarily on your advice in other threads, I'm leery of playing with the TPS, now considering the PC...

sorry for thread creep

I think I can dig something up for you, but let's put it in a different thread.

Muchos Gracias!

Andy's bike 350S....the thing is full afterburner with the simple edition of the PC5 and slip on muffler.

What has ZipTy discovered regarding the TPS.

On the S models it may create a dangerous condition causing engine damage. Best to talk to Tinken.

It's actually the same on S and non-S models, but the non-S models have a little more leeway due to the richer condition. Increasing the voltage on the TPS pushes the map forward which results in a richer condition. It also pushes the timing map forward which is beyond the limits of this engine. I know of one instance recently which resulted in catastrophic engine failure in only 5 miles of riding at the higher voltage on the tps. This was on a 2015 FE501s.

My recommendation is not to advance the TPS. Instead either advance your fuel timings with a KTM user setting tool for non-S models or with a fuel tuner such as a Powercommander on the S models. That way fuel may be added without the additional timing advance.

OK. One instance. Can you unequivocally assign blame to the TPS setting? Engine failure after only 5 miles seems suspect. What was the TPS set to? I can see going to something like 0.67V or 0.68V being a problem, especially at altitude. But bumping up from 0.57 to 0.6-0.63 should not be an issue. Many, many KTM's, and now Husky's, are running with TPS adjusted to something higher than stock.

Yes! I don't understand the obsession to move the TPS settings. It creates a host of problems as the complete fuel and ignition table gets shifted. It's like moving your wall because the hose to water the plants is too short.
Common issues of moving the TPS are: bad idle, hard to start or not at all, erratic revs, blowing up engines due to high ignition advance and detonation. Just get a Powercommander and do it properly!

I know heaps of bikes run Ok after it has been moved a bit but wait till you away from home and have to put shitty fuel in or it's a really hot day...worth the risk, don't think so.

I hear what you're saying but I think that moderation is the key. My 501S was at .58 and I moved it to .65 along with desmog, can screen removal and filter mod. It runs fantastic, idles smoothly, throttles smoothly and still excellent gas mileage. From my perspective, there is a little paranoia being spread about TPS mods but in about 500 miles on mine...I'm good to go without a PC or any other of the add-ons.

There has been more than one instance and Yes, KTM tore the bike completely down and inspected everything. And no amount of tps tweaking will make a bike run as it should. It's not the tps voltage that's at fault here, the fuel mapping is what needs to be adjusted.

I am in the same boat. I adjusted mine to 0.62 as I live at 6500 ft and generally go up from there. In more than 500 miles of riding I have had zero issues and my bikes runs smoothly with no issues apparent to me. But I am certainly not a pro so it's possible I am missing something.
