T4U for Tesla

YOUR BATTERY HEALTH FOR REAL 8.9.3 : Update for Model Y SR Your Tesla now continuously reports the energy actually left in its pack. T4U reads that figure straight from the vehicle's computer, even while parked. No more deriving health from displayed range. The direct consequence: one single figure everywhere — home, diagnostics, shareable card and widget. It stays on screen even with no connection. PACK DIAGNOSTICS, CELL BY CELL Voltage spread between brick groups, thermal spread between modules, internal resistance, open-circuit voltage, real cycle count. Every weak point is identified by its number inside the pack. A WIDGET THAT NO LONGER GOES STALE The widget updates while the car sleeps and while the app stays closed for days. Charge, range and health, current on your home screen. REDESIGNED HOME SCREEN Every pack reading now sits in one place. High voltage safety no longer takes up room while everything is fine — and becomes impossible to miss if anything is wrong. DRIVING EFFICIENCY Now based on your own car's range estimate compared with its rated range. One value per day, steadier and fairer. ALSO IMPROVED - Far more reliable connection to your Tesla account: no more unexplained sign-outs - Hardened access to your diagnostic data - Every reading now states how it was obtained, and when - Displayed range corrected, now matching your car's own screen - Numerous display fixes Thank you for the feedback — keep it coming, it genuinely shapes what we work on.
