Default K210 G2 Dripping on startup

Hello,
I've recently had to switch fuel back to diesel and I can't seem to get a good clean start out of this engine anymore. I was using pure kerosene before and had no issues but now, no matter what I try in the settings - increasing the pump to make the startup faster, decreasing it to make it more lean, adding duty cycle to switch more fuel to the main injectors or decreasing it to again make it more lean... a few drops of fuel always end up dripping out of the tail cone during the stage after switchover, no matter what I do. I don't get flames so it's not that big of an issue, but it is troublesome and annoying because it fouls up the airplane and because I need to put extra care preflighting to make sure the fuel has been cleaned up before closing the airplane and taking off.
I am at a loss because I have had kingtech engines for many years and never had this problem, with G1 or G2 ECU. Anyone have any tips on how to solve this? (going back to the previous fuel is not an option unfortunately)
Thanks!

My brand new kingtech k210 g2 had the same on first start. Fuel drips from the cone , nothing happened but I am afraid to put it on a fuselage, because it might cause serious problem. Any suggestions???

Is this still in the same plane? Or have you changed the installation too when you changed fuels?

Same everything.
What I did notice is the winter diesel seems to drip more than the summer fuel. I wonder what kinda crap is in there

Winter diesel depending on where you live, will have a winter additives in it, so it won’t freeze as easy as summer one which become like a gel and a few thing for starting ect….in really cold temp for truckers it work very well….
