Unfortunately it looks like I binned the PCB. I do have a knock sensor IC from a dead 3VZ-FE ECU, the IC part number is D151802-8860. I also have a faulty main MCU from a later MR2 ECU, part number D151803-9651 if you'd like to look at that as well.
DIP40? The photos I've seen show a DIP42 package. Post 686 on this thread has a photo of a ROM reader board which can read DIP42 CPUs.Is there any info or any progress being made on the 3S-GE engine's ECU? That is the NA engine in the Celica ST165 and ST185.
The Ecu's got the DIP40 packaged CPU, and i've always wanted to dump the content of the rom and make a daughterboard with external DIP28 27C256 that will allow me to use the Ostrich 2.0 emulator and tune the software for wilder cams etc.
