Sim on m56 engine
For the M56 SULEV: I built/installed the sim and also fool the SAP MAF. So far still no P1418 code.
So, I needed to do both on the M56 1. Add the sim as per Drewfus2101 and 2. Add the voltage divider to the MAF connector.
O--10k--- - GND pin
O--10k--- - 5V pin
O-------- - Sig pin (2.5V)
