I actually need two ECU's, one that I can "destroy" - remove the processor and install it in my adapter to obtain an MCU read with. I could probably remove the processor and install an 84 pin socket so that I could re-install it - but I haven't done this before and I couldn't gaurantee that it would be successful - especially with my lack of a proper SMD rework station. I am a subscriber to the waste not-want-not school of thought so I would like to do this to an already broken ECU, then it would be simply a gamble in order to get it working properly again. Someone out there must have a broken ECU.
The other ECU I need would have to be working. I would need to hang on to this ECU for a few months in order to fully experiment with it, but I can promise to return it in working order with the addition of a socket installed. If I can get my RAM/ROM dump program working, I may not even need the above ^. I am currently experimenting with it and the results are promising. I can read the internal MCU programming one byte at a time through the serial port, but once I send it into a loop it locks up the ECU.
The 95-96 ECUs aren't viable candidates at this time. Ducaticraig sent me some pictures of the internals and they mirror the updates made to the Acura RL (replacement for Legend *snicker*) ECUs, which I've studied some. They are 100% internal MASK ROM embedded on chip with no flash available. They are also copy protected so I cannot obtain a read of them with my adapter. There are companies that can get a forceful read of the processor but it costs upwards of $200 - $300, I would need to see a real interest before investing in that. In order to "chip" them, a read would have to be obtained, disassembled, fuel and ignition maps and other variables identified. Then, an 84pin socket is installed in its place and *NEW* processor is programmed with the modified software and installed into the socket. The processor is only programmable once so this can get expensive fast.
I am a die hard Legend fan. My shop is in Bristol and we are one of a kind in that we specialize in (and love) the Legend. My claim to fame is in professionally swapping in the 3.5RL motors with the Type II parts "The 3.5 Hybrid" to alleviate the well known head gasket problem with the C32A1 and to improve performance. Here are a few pictures of my showroom loaded up from the last turkey day meet 11/28/10:
