My bad on asking about Techstream software.
Does anyone have any idea as to what the cost of the full version would be, or if a non-Toyota tech could even buy it?

Or, what software are others using to log data? I want to look at getting a tune but think it would help to provide some vehicle data to get a more optimum tune.

 

$1095 annually. I have a subscription. I am not a Lexus tech, and my work is in an unrelated field.

 

Think there are some blutooth/wifi dongle + mobile phone apps that let you datalog. Probably no where near as powerful as much information as techstream but better than nothing.

 

Yeah, thanks. I looked into things a little more and will probably go with dashcommand to start with. I'd really like Techstream but can't justify the cost for what I'd use it for.

Thanks again-
