Which OBD scanner is anyone using that displays open/closed loop? Does it change and show the status of the open/closed loop?
Do I need Torque PRO?
My Innovate LM-2 shows open loop ON or OFF. When ON, the fuel trims do not change(and the fuel trim display stays at the previous value), and when OFF, they do change(cause the pcm is using the o2 data), so even scanners that display fuel trims can give you a clue. Do you have a wideband o2? If not, then I highly recommend the LM-2 as a wideband o2/obd2 scanner/datalogger in one package.
