Automatic temp spoofer available

Yes, I use Hybrid Assistant daily to observe all stages of engine operation. I asked if the spoofer will work with the Prius C / Aqua. I asked this because OP designed the spoofer to work with a gen 2 Prius. The Prius C / Aqua has the same engine operating procedures as a gen 3 but with the 1.5L engine of a gen 2.

 

The engine operation stages are the same. You can see this through the program.

But the spoofer automatically works with a specific engine ECU. I believe that it uses certain levels of electrical parameters calculated for a specific ECU.
These parameters may be different in different cars.
In order not to harm your car, I would not recommend using a spoofer for the Prius C that is configured to work with GEN2.
First, try manually selecting the resistances that simulate the engine sensor temperature.
