Looks like about 1E-2D would be the security data for the ECU link, 3 strings are sent in the relink and this is right size, data changed on the first relink but not after that.

Other bytes might be related to options? and pin codes.

Well I think that is enough for the eprom for the time being.
Started looking more into getting a ROM dump from the mcu, cheeky engineers have tied the uart RX pin to the reset output of the 5V reg ic....

Finally got a chance to get back to this, darn life n shit getting in the way, let the hackery begin when I get more time........
Fun time to be had programming something like an arduino/esp32 to read/program the microcontroller as the only options being commercial are way out of hobby league, it's only 3 wires, how hard can it be?

Darn manual labour..... used to be able to punch out console mods with more wires faster than this took me to solder.
