datalogging with aem wideband.
this is the part in the instructions where im confused "RS 232 serial data output port for data logging without an engine management system" . what exactly do i do with the wire?
I know you can view it thru HyperTerminal but it would not do you any good without a way to log
AFR against MAP or at least RPM ect.
An external data logger is your best bet.
