About this item
Hey there!
So, you're about to swap out your car battery or mess with the ECU, and you're worried about losing all your radio presets, engine learn data, and security codes?
Yeah, we've all been there.
Super annoying.
That's where this little gadget comes in to save the day (and your settings).
It's an OBD2 Memory Saver.
You just plug it into your car's OBDII port under the dash, connect a 9V battery (not included, gotta grab one of those), and boom – your car's computer thinks it's still connected to the main battery.
It supports CAN, EOBD, and standard OBD systems, works with most passenger vehicles, and even has a 1-year warranty.
The part number is CNBJ-550-PLUS.
It's a simple, unbranded tool that does a very important job.
Keep your tunes and your engine happy while you work!
