I will not recommend this. Firstly, if you go through diagnostic mode then there is no option for freeze frame data. Secondly, when live data is displayed this unit becomes very slow and it takes time to go through different parameters. Thirdly graph does not have any axis. Fourthly it claims to be for japanese cars but it struggles to intereact with different parts. For my honda odyssey 2000 it only interacts with AT and SAS but not with Engine. For me its $300 wasted. Not user friendly.
