530i e34 swap m60b44

[cordeiroservice]

some help please. Swaped the b30 for a b44. but I used only block and heads. the rest all of the b30, includes ecu. perfect. However, I feel limitation above 4000 rpm. Bought the manilfold b40 (large) throttle and maf. then it ruined in low rotation and every now and then I find trans program accusing throttle failure. It was weak from low rpm. any tips?

Just to clarify your question: You are trying to use an M60B30 ECU to run an M60B44 hybrid, and you are wondering why the combo isn’t running great?
