Hello all, just purchased an elm327 for my veh. trying to narrow down the cause of a lean code on bank2. I downloaded the free torque lite on my phone, but don’t see anything about fuel trim readings. does the paid version supply that? Thanks

Torque Pro definitely does do that. With the ELM327 in hand, you are only Four dollars & ninety-five cents away from one of best code readers around. GET PRO.

I would go one step further. 99% chance a lean code is a vacuum leak. There is no better, faster, simpler method of identifying a vacuum leak than monitor Fuel Trims & O2 sensors on both banks while using an “un-light” Propane Torch and blow propane all around vacuum lines, break booster hoses, PVC valve, bottom ‘O’ rings on injectors, around / under intake manifold and even the OIL filler spout.

You hit a vacuum leak, fuel trim and O2 sensor on that bank will immediately go NUTS.
