Little update....video is in Toronto being examined...Ive also added that while my machine sat outside in -30c temperatures for a couple days it started quicker than it would have at -10c or freezing. The first try at starting when -30c it actually ran for 5 seconds and then stalled, second time it ran right away. SOmetimes it would be on the first try it woul go. Obviously labours to start when its that cold but it doesnt take the usual three times. Im thinking with these machines running on premium the ecu is not sending the right messages for startup but well see
Sounds like its not getting enough fuel at start up. That should be easy to program to fix.
Alan ulmer indicated that they are actually too rich on start up. Then most of the upper rpm fuel curve is too leanSled Dog said:
Well is the problem the ignition is shutting it off which would make no sense when trying to start the sled or a fuel delivery problem? I would say that has to be figured out first.
