Not easy if you haven't done it before, you need hot air to remove it, and is probably coated with laquer that needs removing first.

Open the ecu and look for a small chip half size of your smallest finger nail, 8 legs and should have 93C46 on it, see what you think.

Or do you have any local tuners near you, all decent ones have this gear, you're welcome to send them to me if you get stuck.
