Default 335is Dct hybrid turbo, hesitation - 04-12-2021, 04:33 PM

So full story: we had a 135i with hybrid on @25ishpsi with all the same mods listed below that ran flawlessly . The 135i decided togo single turbo so the setup was sold to this 335is Dct .

Car has jb4 backend flash , hybrid e85 port injection bef, index 12s , 450lpfp,
New delfi coils , ngk plugs @.20 , put all new intake gaskets and port gaskets, new valve cover gasket.

Jb4 setting: duty bias all 50 // fuel bias I moved around to make the best af for port// open fuel loop @0 // disabled ff rpm gain. Same settings I had on the 135i.
So with all that being said , car on map 2 will make a clean pull.
Car @22ish and up will have a soft hesitation in 3/4gear but fully cleans on 5gear.
Iíve noticed fuel trims have been low compared to other cars with the same setup.

Youíll notice the fuel trims climb nice and together with the 135i log
But with the 335is itís kinda all over the place.

Second log is the 135i .
First log is the 335is. You can see the rpm line is not smooth.

Without looking at the logs it sounds like you need fuel. Check the LPFP or HPFP.
