Got a BIG problem and need help! Installed triple filters, downloaded Hans tune, did all the resets, 12 minute adaptations and all was well. Hooked up the Dobeck 4+, started engine, it ran 20 seconds, then shutdown (got error code for injector 1,2,3). Reset code and disconnected all the Dobeck stuff and went back to stock. Now the engine will turn over and get fuel as raw fuel ran out the exhaust (fuel dripped to the ground from the exhaust). I think I am not getting spark! Fuses all good. Is there an inline fuse that controls the current to the coils? I quit as the bike smells of fuel and am afraid the stupid thing will catch fire! HELP me please or I will not be able to sleep at night!

Make sure you're not getting spark. With that much fuel out the pipe could be drowning the plugs.
 
Did you download the tune you had in the bike before installing the new one? your plugs are going to be pretty wet remove them dry and gap and get all the fuel out of the cylinders easy way is to-remove the-plugs and wave a flame over the the openings and woosh away the gas goes.
probably nothing serious and be patient more help (better help) will be along soon.
 
I did save the OEM (TOR) tune, am afraid to wave anything associated with fire near the bike as it reeks of fuel. Funny how much fuel the injectors pump with only three short starter engagements. I did forget to add in my woes paragraph that the reason the engine shutdown might be that I failed to connect the positive lead into the battery. It was touching the post under the other wires I hooked up, so allowed it to start but lost contact and shutdown the engine. Would that cause the ignition system to quit working or cause the installed tune to screw up?
 
Does anyone know what to disconnect so I can motor the engine without the injectors squirting fuel? I unplugged them but the engine wont turn over when unplugged. I would like to motor the engine to flush out the excess fuel and check for spark.
 
Make sure your insurance is current....
Take the plugs out the fuel will evaporate in time or blow out with compressed air (That's probably what i would do)
take the fuel pump fuse out - maybe.
 
With no spark plugs you should be able to turn the engine by pushing it in gear with ignition off - you might want someone to help with this.
 
I did pull the plugs which were wet, pulled the exhaust (collector had almost a cup of fuel inside!), drained the oil in the sump which seemed to be gas free, checked the spark plug holes also no pooled fuel. Put it back together and reloaded the tune back in the ECM, motored no more than 5 seconds, same thing with no start and gobs of fuel! Cleaned all up again, put the original dealer TOR tune in the ECM, You guessed it, same thing. I am not the sharpest knife in the drawer but I think my ECM bit the dust-Ouch. Looking online, seems Triumph has had problems with certain ECMs for 2014-2015 models which caused the ECM to dump too much fuel into the engine- just like mine is doing? Time to call the dealer.

Running the bike without the battery in the circuit could have caused big problems. If you get the engine running and disconnect the battery, there is no reference voltage for the regulator which could cause the voltage to spike causing coil, light bulb, ecm and other electronic failures.

I once had a fellow start his boat with the battery from his truck, after it started, he removed the battery and drove the boat around the lake until it quit. That little run fried every coil in the boat. Tach was cooked, oil injection solenoid fried along with the ignition coils and a couple of light bulbs for the running lights. I've seen voltages climb on some vehicles to over 100 volts. Typically a voltage spike won't fry a coil right away like a light bulb so there shouldn't be any major issues with yours since it only idled for a few seconds. My only concern is the ECM given the fact that there might be no spark now. The ECM might be a bit more voltage sensitive and prone to failure. Hope that isn't the case and the engine is only flooded.
