Re: E46 330i supercharger ICV delete?

Yeah, I think you're finding that deleting the ICV is just putting a band-aid on a bigger problem. We checked the disassembly and there appears to be only a couple ways around these DTCs. The first is a curve called IP_TPS_MAX_TPS_RATIO_DIAG. The second is a parameter C_VB_MIN_MTC_CTL_DIAG. This is probably a safety critical component, so we won't offer any advice on how to "tune" this; you're on your own! There are also three other parameters that determine if it throws 0xA0 vs. 0xA1: C_MTCPWM_PI_MAX_DIAG, C_T_MTCPWM_PI_DIAG_CUR_OFF, C_T_MTCPWM_PI_DIAG.
Did you try flashing the 330i supercharger tune we made available on our forums? This one worked fine for us when we helped with another customer's car. Again, there shouldn't be any need to delete the ICV when doing forced induction.
