Yaris ECU Reverse Engineering Progress

[Nexus1155]

Yeah, i was going to get into the BMW bandwagon and play with the new tricore hardware, but thats at a later date and when i have more money for R&D. A reflash will be cheaper by all means atleast if it comes from me, because i know how costly something can be...

Atleast when all is said and done i will atleast have access to throttle maps, fuel, ignition, O2 sensors, etc, which is needed for a basic tune, the more complicated stuff i can work out later.

If i were trying to crack it through OBD, maybe, but ive dealt with encryption before on the Audi ECU's. When you are dealing with something that has direct contact with the MCU, i doubt there will be an encryption since it is such a mundane way of programming the ecu directly from the factory... Now if they removed a resistor to short out the communication, then ill be screwed...
