Mapped ECUs how to spot a fake

[Simon]

As there has been a few instances of fake mapped ECU come up i thought i would share these pictures.

I brought a starlet that i knew had been modified in Japan there were no external fuel modifications that i could spot and this is how the ECU looked:

Looks standard enough no stickers or seals but i was sure there was something done to the ECU so i opened it up:

Here you can clearly see the daughter board that has been fitted to alow the use of a chip that can be written to form the specific map on that car. As far as i'm aware nobody has managed to connect to a stock toyota ecu and rewrite onto the chip that toyota fits thats why tuners have to oprn the ecu and solder the new daughter board in onto the motherboard.

If you ever have doubts about an ECU ask for some pictures of the board this should prove it has been altered but not if it's still working or not.
