There was once a guy that shared instructions on how to resolder that chip (Get dump of software, root it, solder new chip with more memory). It was instruction on how to root Tesla. But oh, he deleted his content and left some comments: > As a result I've taken down my howtos. I'm sorry about this but there is some kind of political problem which I don't understand. https://www.diyelectriccar.com/forums/showthread.php/howto-tesla-rooting-firmware-199457.html https://www.diyelectriccar.com/forums/showthread.php/howto-t... Pity the site is not available on waybackmachine.

I'd be surprised if it's any different to modding your BIOS in a PC motherboard: Buy a SOIC-8 clamp, a USB interface and bob's your uncle. Unless the ECU is potted in epoxy.

  Doubt it’s an SOIC. More likely a 40 or 48 pin TSOP or the like. But if it was an SOIC... just lift the power pin, power the chip externally and find some other points to tap into the clock and data lines and dump away. Then solder the legs of the new one on one side and connect VCC on the other side.
