Today , on start up ,i noticed her V,lumpy , on inspection she was off on the LHS cylinder , i removed the spark plug ,great spark , great compression , but i wonder why i didnt get the smell of petrol … Dialled up the “Menu” and nothing showing on the faults lists.

Worth checking the electrical/fuel connectors to LH injector.G.
The bike "diagnosis" ECU 27 which is LHS Injector ,all connectors seem clean and bright , just going to change , the Lhs to the rhs to see if shes off when i change them about..HT leads are exact length. Mine worked lose one side
She has a great spark on both sides. Injectors changed round , still not firing on LH Cylinder. Volt meter shows LHS connectors are at 1.2 , RHS connectors are 1.9 , chasing wires now !....Pulled the Injectors Relay , No real signs of corrosion . Clipped off the ECU cover , front connector looked fine ,rear most one doesnt look to hot ,a lot of a Bluey type gunge ,and it looks like some of the prongs may be damaged ? ?
Sounds like the dreaded negative path corrosion, the best product to sort this is an aircraft anti-corrosion spray, ACF50, this is brilliant on copper, brass and aluminium, Motomecca stock it if you cannot find it locally.Cheers, Gerry.
I only wish it was a bad earth . I suppose it was a few bad earths . Blue goo !. Now just for good measure , I have one of the wee pins stuck up inside the connector ! ..... Balls Have any of you any idea of , 1 , if this can be repaired , 2 , who can do it , 3 , how do i get the one remaining pin out ?Magneti Marelli IAW 5AM This unit is not spefic to the Stelvio , i see it on Some ducatis , and a lot of Fiat cars , Any info on the different applications ,and what would work for me would be good
