I have a 2012 Ultra Ltd. Installed the PV auto tune pro yesterday and went for a ride to do some logging. Well I screwed it up somehow and didn't properly download the learned values. Went out today to take another ride but bike wouldn't start. Fuel pump will not come on. Did lots of checking and found that there is no power to the fuel pump fuse. Also tried to reflash the ECU but the PV says no ECU connected. I believe that has something to do with the fuel pump not being powered. Any ideas!

 

I'd disconnect tuner and check all the fuses- incl. pulling the main fuse for a few minutes to see if this does a reset.

then try.

if still dead and under warranty, call the dealer and do not say a thing about the tuner.

Thanks Mike. Did all those things and still no power to the fuse. Even if I remove the PV, auto tune pro module and the wide band sensors, which is a bit of work, there would know regardless because of the custom tune in the ECU, yes? Can't get rid of that either because the PV won't let me reflash the ECU. Error message says "ECU cannot be detected" , which I believe has something to do with the fuel pump power problem.

 

warranty?

you did check the kill switch--- does the motor crank when you push the starter?


this post will only bump you up- my wiring diagram is for an 09 and I know your model has advanced wiring.

there is a relay on the fuse for the fuel pump on the 09- if that were to go


I am not up on the tuners...by choice

Yeah, put some super glue on the kill swich in the run position head.
