te449 hot start and idling issue

does anyone have any info on a diagnostic tool for the te449. will the gs911 tool for bmw,s work for this bike. if not ,which will and where can i purchase it. how much?

My bike requires a small amount of throttle on hot starts, perhaps 1/8th. Otherwise it just cranks.

Mine (2008 Husqvarna 450 TE i.e.), also requires a small amount of throttle, but on cold starts. Otherwise, without the small amount of throttle, I have popping/detonations and no start. I took out the spark plug and it's black.
I've checked the fuel pump, fuel filter, injector, and everything ok.
But I can not start the engine without a small amount of throttle, and after it starts, the idle is fluctuating between 1650 - 2300 rpm.

Has the secondary butterfly been removed? Reason I ask is that I tried remove mine with map 3 caused all kinds of surging and stalling reinstalled all went back to normal. Awhile back I ran into a new issue while out riding bike would die not start until throttle body did it's r2 d2 thing then would start but die or sputter very frustrating spent days trouble shooting and it literally was the ground at the back of the transmission. Fyi butterfly was a success with pcv installed!

Interesting you had issues with the butterfly on Map 3.

Heaps of bikes on our FB group (mine included) on map3 and no butterfly. Possibly the start of your earth issue perhaps, and just a coincidence.

finally got bike back from 2nd shop i left it at (about 175 miles from home ...these bikes not popular in n.y.!!!) it was a combination of fuel pump and ignition coil. what a nightmare . hopefully NO MORE ISSUES!

Fingers crossed!!!
Doesn't sound like they knew what it was doing when replacing two components....
