Has anyone used/is using any of the OBD meters currently on the market? I want a bit more monitoring ability but due to warranty I can't install aftermarket gauges that require fitting sensors/cutting lines etc. Well I can but have to change everything back to stock every time the car goes to the dealer and if something breaks when I'm away from home this may not be possible.
There are a bunch of ODB Multi-Info meters available here in Japan from Blitz, Greddy, DEFI, as well as the usual Android/iPhone set-ups etc but I I'm not sure which way to go. I remember the ECUData scan seemed to work well but is not available anymore. I'm mainly after boost reading but am not really sure if the ECU gives live boost, obviously corrected from MAP/AAP, or just monitors for under/overboost situations.
