What is happening is the data for RPM's is very choppy; or the most noticeably choppy. I'm using an ELM327 mini adapter and the Track Recorder add on for the Torque app. (Then using Race Render free and a gopro video to add it all together)
Does anyone have any suggestions on getting better/quicker data? It seems like there might be other apps focused only on track recording but Torque is what I have at the moment.
Do some research on the OBDLink products, I have both the ELM 327 and the OBDLink LX but sadly the car is a week or two out so I can't comment if it is indeed faster. It claims to be up to 4 times faster and is certainly a nice well made unit.
