Tps setting closed throttle setting

Hi
i own a husaberg 570 FE 2012
i was experiencing alot of flame outs and under power issues
long story short it turns out the tps was out of adjustment
using a multimeter i checked what it was set at it read .408v in the closed throttle position so i done alot of digging around to find out what it is supposed to be and had no luck so i got the correct stock setting
.601v at closed throttle
all my problems disappeared once i adjusted it to around that a little over is better than under
the tps is know to bump around and lose its position because its only held in by one screw
a hard knock will put it out of adjustment worth checking if your having problems

Can you go into any more detail on how you adjusted it? pictures perhaps? and how did you find the correct closed throttle position setting?

Cheers.

Hi On the tps there is a plug with 3 wires You want the yellow and black wire
While its all plugged in using sewing pins push into the wire so you can connect the multimeter to read the values
the black lead goes on the black wire and the red lead goes on the yelow wire On the meter select the minimum dc setting so it can read less than 1volt in detail should look like 0.000 depending on the multimeter
Now once its all connected tap the start button to get the power on you should now see what it reads
To adjust it you lossen the screw on the tps and turn it anticlockwise to make the values go up and clockwise to come down you may have to keep taping the start button to keep the power up to it while you adjust it or you can do it running but not advised because its so sensitive
it changes even doing the screw back up
Im going playing around with it again later theis week instaling jd jetting efi tuner ill take photos then and post here showing what i mean
and about the way the wires are conected its the only way i could do it as i have not found the plugs to make a connection lead between the tps and the wireing harness
Thanks from tourist

In regards to the correct tps setting i found out from ktm mechanic making out i had the breakout kit and said i purchased a new tps for my bike and was wanting to know what the setting was because the instructions it came with did not have the stock setting To be sure i rang 3 different stores and got the same results

If the value is less than 0.601 what is happening is when mine was 0.408 at idle when you open the throttle the fuel injector wont give any more fuel to the engine untill the tps has gone past 0.601 hence causing flame out high air ratio not enough fuel
Even though the stock setting is 0.601 i set mine at 0.630 it has made it a little rich at idle but has made the throttle more responsive
It works for me

Cheers nathanz,

If you can put up some more info when you fit the JD tuner that would be great. I think my FS570 could definitely use a TPS adjustment i just wasn't sure how to go about it until i saw this thread. Little nervous about pushing sewing pins into the wiring though haha! is there another way to do it?
Thanks from nathanz

Sewing pins work great, you can push them in at the cdi box

jd tuner

I bought a used one of these and it is fun to play around with after I got it working... The thing was full of sand and corrosion when I bought it. I fixed frayed wires and siliconed the entire perimeter inside and out... It is not waterproof!!

It actually got me out of a bad situation once. I bought a used fuel pump which had been sitting dry for a bit. When I installed this fuel pump, the filter inside the tank must've dislodged some fibers which were sent to the filter in the injector. The bike kept running leaner the further I went. I just kept upping the fuel output on the tuner. I didn't make it all the way home but it got me out of the woods before the bike ran so lean that she wouldn't even start.
Thanks from nathanz
