Bosch 4.9 wideband sensor

Post by Totalnova »

So I have a bosch 4.9 sensor on my AEM gauge with intergrated controller I have it set up with my sS40 ecu but I just want to make sure it's configured correctly, will one of the sensor scales all ready set up work or do I need to manually enter them, if so how do I go about doing this?

Thanks Nick

There's no preset for the AEM gauge.
Just fill in the voltage to lambda/AFR table from the AEM manual.
