Good info to know... Can the standard 07K 2.5L Beetle/Rabbit/Jetta ECU control the N75? Can you forsee any CANBUS issues (missing message from instrument cluster, ABS module communication)?
CW_CAN_R will take care of any CAN-BUS errors. That's the very least of your issues. As for N75 control, probably not, but I'd rather have wideband anyway.
