That's an interesting idea for Bimmer's aero grill, and it should be very yeasy to fabricate something similar. I'm just thinking if I won't use one "kidney" as an inlet for ram air setup, but that's just thoughts for now. Anyway I'm working now on MPGduino setup for Berta, and it's pain in the .... because of my huge LCD display and no good place to put is on the dash. Then I'm planning a kill switch, because Berta engine's running in period is about to finish. Then tempomat and manual accelerator linkage, then some aero mods finally.
