Nissan JECS ECU RE: I another new guy.....

[BOWEN, SCOTT M. (JSC-CC)]

Yup, that is my problem, no removable EPROM...
But Jim Wolf adds an EPROM/Daughter Board via the 40 pin port that is on the
board in the ECU[#A12-001 B57]...

I am trying to figure out how to do this.....

Or find the equivalent chips that Nissan/JECS uses and replace them with
something I can FLASH.

A neighbor and I popped open the ECU of an '85 or so 300ZX engine.  It
used a Motorola 6802 along with several other 40 pin DIPs.  It appeared
to have a mask ROM or an OTP PROM.  There was no unplugable EPROM.
