Ok guys, I've done a little searching, and I have a question.
Let me start off by explaining my situation. My roomate has a 2005 Accord Auto. We are getting into electrical engineering, and as a project we decided to try to get into his ECU. But he didnt' want me fiddling with it, so I bought one out of a junkyard. I was expecting to find an OKI chip, which is what Honda has traditionally used. Long story short, it has a SH7058. I just found out today that many subaru ecus have that same chip. I went on the Renesas website and downloaded the manual for the chip, but they don't say anything about getting a rom dump off the thing. I looked at the way we have traditionally gotten rom dumps, and it usually involves loading a Rom Dumper program onto the stock chip through the external eeprom spot on Honda's OBD I ecus.
From what I've read so far, it seems that you guys have found a way to get the ROM off the ecu through the OBD II port. My question is:
How did you get the stock ecu to give you its rom?
