Description
Built for your Model 3 & Y, not bolted on
SCDI is engineered around the electrical architecture of the Tesla Model 3 and Model Y. It sits quietly inside the car and works the moment it is connected. No subscriptions, no app maze.
What it does
- Smarter charging: live charge insight and protection tuned to the Model 3 / Y battery, so Supercharger sessions are efficient and gentle on the pack.
- Hidden diagnostics: state of health, cell balance and fault codes at a glance.
- Seamless install: one module, plug-and-play harness, no splicing. Reversible in seconds and leaves no trace.
Compatibility
- Model 3 and Model 3 Highland
- Model Y and new Model Y
Install in three steps
- Pick your car (Model 3 or Model Y).
- Click it in with the plug-and-play harness (about ten minutes, no tools).
- Drive. Reverse it any time.
