OBD2 Memory Saver ECU Emergency Power Supply Cigarette Lighter Cable

Stop the Reset: Professional OBD2 ECU Memory Saver & Emergency 12V Power Link

Who It’s For: Engineered for the DIY mechanic and the performance enthusiast running any 1996+ OBD2-equipped vehicle. If you are tired of your car idling like trash or losing your custom settings every time you swap a battery, this is a mandatory tool for your box.

The Symptom: Modern Engine Control Units (ECUs) rely on volatile memory to store "Long Term Fuel Trims" (LTFT), idle air bypass settings, and transmission adaptive learning. When you disconnect the battery, that voltage drop wipes this data clean, often resulting in a sluggish engine, erratic idling, or even security lockouts on high-end audio systems. You aren’t just losing your radio presets; you’re forcing the engine to spend the next 50 miles re-calculating its entire combustion strategy from scratch.

The Engineering Fix: This system utilizes a high-conductivity 10-foot cable to create a bridge between an external 12V source and your vehicle’s OBD2 diagnostic port. By back-feeding the electrical system with a low-amperage steady current, we keep the ECU energized while the main battery is out of the loop. It maintains the internal clock of the processor, ensuring that your digital settings, seat positions, and critical ABS/Anti-skid calibrations remain exactly where they were when you turned the key off.

Why Mechanics Choose This Kit

• Adaptive Memory Retention: Prevents the ECU from resetting to factory "base maps," maintaining your engine’s optimized fuel and timing trims.
• Total System Coverage: Keeps power flowing to the dashboard, digital clock, stereo settings, memory seats, and power window modules.
• Extended Reach Design: The 3.2-meter (10ft) cable allows you to easily connect to a jump starter or a secondary vehicle without crowding the engine bay.

The Performance Promise

Expert Advice for Installation: When using this cable, always insulate the positive battery terminal once removed from the battery post. Because this tool keeps the system "live," touching that terminal to the chassis will cause a short. Do not attempt to start the vehicle or turn the ignition to "On" while the memory saver is connected. Buy with confidence. Backed by real automotive experts and fast shipping.
