I have a 2007 Lexus GS450h hybrid that I’m planning to use as a donor car for an EV conversion.
The car is complete and working but I want to catalog as much of the CANbus data for future integration and control purposes before taking the car apart.
My plan is to use the OBDii splitter cable to connect Techstream to a laptop as well as SaavyCAN at the same time.
Techstream is Toyota’s diagnostic software which is capable of triggering the car’s controls and devices on command such as Hazard Lights or Warning Buzzer etc. However it does not display what CAN commands are being issued or being returned.
I want to issue the commands with Techstream and listen and capture the CANbus data with SaavyCAN and a Macchina M2 on the OBDii splitter cable. Ideally on the same laptop with different USB ports, but possibly on separate laptops if that won’t work.
What I’d like to know is if this setup would be expected to work or if there’s something fundamental I’m missing.
