The OBDII output simulates an auxiliary ECU signal when plugged into a vehicle\u2019s OBD port, which requires a unique address from the other ECUs already on a vehicle\u2019s network. AEM\u2019s default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary.<\/p>\n<p>Accurate AFR data is critical when tuning an engine. Running rich (very low air\/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air\/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air\/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency.
