which pipe and which fuel map on the ecu?
which pipe and which fuel map on the ecu?
Akrapovic exhaust and whatever the factory KTM map is... Not sure. The latest update is the problem was apparently solved by KTM. They flew one of the race techs in to troubleshoot the bike it was determined to be a faulty throttle body. So now it idles and runs although the check engine light is back on now. So it is back at the dealer. They claim it won't take a month this time. So hopefully that knowledge will help someone in the future.

So how did you get on Bags?
Did they replace the whole throttle body to solve the problem with the idle?
I have unfortunately had very similar problems with the idle being very rough and when you finally go to take off and put it in gear it just dies. Argggggggggggg !
My bike has done around 8500 ks now and the problem seemed to lessen over time - UntillI installed the Bazzaz EFI and wow it made a huge difference idle was smooth and was perfect - for about 3 days and then back to crap idle and cutting off with the slightest throttle twist and dies when you put it into gear - anyone help please - Not sure if the bike would be covered with any warranty now after installing the Bazzaz - All I want is to sort this idle and stalling issue thanks

Sounds like nothing to do with the electronics, more likely something mechanical such as the solutions mentioned before. Dies when put into gear? Could be the sidestand switch, too. I'd try removing the Bazzaz EFI first, though.

My stalling while idling cold is gone now after I install my power commander 5
Replacing the throttle body solved the idle problem and the stalling while ridding it as well. Once you rolled off to get it turned it would shut off and bump start itself. I had no aftermarket fuel management installed this was all factory. Although now I have it back at the dealer for a code 23 Speed Sensor? Not sure how that happens since there is no odometer or speed reading on a cup bike.

I did the same thing chrisv102581 and after the install no more stall and idle issues - finally a bike worth riding
This TPS adjustment tool, according to the testimonials on the site, successfully addresses stalling/"flameout" issues on KTM engines. This might be a simple fix for the stalling/engine cutout problems vexing some unlucky owners of both 390 variants. Inexpensive, worth a try.

Very interesting!
I believe that would be a 'clue' to the mystery idle issue, fortunately mine does not suffer the issues, but, shows proper operation of TPS via OBD diagnostics...

check your spark plug/cable. my plug was so loose in the cable that my bike would idle like shit and die randomly. Change the cable to a new cable that fit tightly on the plug and it has never run better!
ecu reset
Had similar problem when I went to pick up my 2017 RC 390 from the dealer. The engine would quit when pulling in the clutch to change gears.The dealer reset the ECU. I had to wait two hours for the engine to cool off. The engine was started and allowed to come up to temperature. This sets a base line temperature in the ECU. This engine will quit if it gets too hot. If this base line procedure may not have been done correctly. The bike may have been run a short time at the factory and the base line temperature would be way off. Give it a shot. I do not see where it could hurt. I suspect there are other problems this procedure would fix.
