No its not soldered in it's part of the harness the harness is 100% part of the FCD. The sticker has air bubbles behind it. I've opened it up as it has 4 screws on the back. The 8 pin chip has had all the details sanded off it so it's unidentifiable as most Jap tuners do and has CEP-27 and 00251-02007 on the PCB there is a variable resistor in it for adjustment but is glued in position so you can't adjust it.
