I bought a JDtuner for my 2011 HUSQVARNA TE511 a little while ago, had it running but i have encountered a problem. I am not close to any bike mechanic that can help me so if you can offer any advice it would be greatly appreciated.
After I installed the tuner i was testing different settings because with the default settings engine was dying at high speed with full throttle. So i lowered some of the ranges and this fixed the dying at the high end.
In trying to find the "mean" settings i lowered some of them a bit more, went to take the bike for a run.... and bike stopped, bit of smoke and fuel fumes pouring out of exhaust. now cannot start. Indications of bike getting too much fuel but considering i was leaning out the settings, not making them richer! therefore doesn't make much sense.
I disconnected the JDtuner and plugged original plug back into fuel injector, still won't start.
I checked for spark and all good there... but then noticed alot of fuel exiting the plug port upon cranking. (too much fuel)
I have removed fuel injector and tested outside the bike, upon cranking the fuel injector sprays a constant "heavy spray" of fuel until i stop cranking (it's like the injector stays fully open and fully on) and then the spray dies down to a stop when I stop cranking, doesn't snap shut off!
At this stage i think the fuel injector has something stuck in it or it has died. I have tried compressed air in reverse direction while toggling power to the injector to see if any obstruction could be dislodged. (no luck)
So i either have a dead fuel injector of have somehow wiped the ECU (but I can't see how I could have done that)
I have put a test light across the 2-wires that hook to the injector and cranked the engine... light lights up and dims out a little while cranking but it seems to be constant, its a bulb type test light and slow to react to any high rate flashing "if there was any".
new info.. I bought a new injector and no difference (waste of $180)
while I had the tank out exploring other idea's I decided to fully flush out both fuel tanks (as i was very surprised to see a fair amount of crap in the first tank and a little bit in the second tank). Anyway I took the fuel pump out of the tank and noticed that filter in the tank was black... I wondered if that was normal or not (didn't know) so I just put it all back together.
is it fair to say it's fooked being black? and if it is fooked then would that cause an over supply of fuel? I would have thought if fooked then it would starve the injector?
