Alas, the MH8106F chip seems rather mysterious. I haven't found a single datasheet for it as yet. This chip seems to often be used for vehicle ECUs, so I suspect that the lack of data is intentional, to make reverse engineering harder, so people can't do dangerous things with their cars. Unfortunately, that means they also can't get information on them for interoperability, or patch undesirable behaviour that the manufacturers don't fix.To make progress with the iMiev ECU firmware, we'd need these things:A binary or hex dump of the flash imageA datasheet for the MH8106F, with at least basic information on what the various special function registers doProbably also a datasheet for the other large IC, IC2. We don't even know which of the several numbers on it are the part number, or who the actual manufacturer is (I doubt that Mitsubishi have their own semiconductor fabrication facility, but I could be wrong).A disassembler / decoder, preferably for Ida Pro.Lots of time and patience.This information has to be "out there", since there seems to be a market in reprogrammed chips for various vehicles, all at high prices. If anyone comes across any free information, I'd be interested.
