Data Request: SR20VE ECU CPU pinout
I'm looking for a pinout of the physical CPU inside the SR20VE ECU, not the connector pinout, the 136pin main CPU inside the ECU. I know its a long shot, but i know there are some pretty switched on people lurking around here...

He is talking about the big square chip which is visible only if you unsrew the ECU cover. I tried in the past finding some datasheets on this without any luck so far. Nissan is probably using CPUs exclusively made for this use and the company that made them is paid NOT to release the datasheets. Reverse engineering is not an option. If you know your way around these stuff there is a chance that you find something identical to this with a different part number but I find it extremely hard to do so.

If worst came to worst can't you follow the harness/connector pinouts for the leads that you need to the points to the CPU and snag them that way? Are you just trying to install a daughterboard on the VE ecu?
