Nissan 300 ZX

[Roy]

Hi There to all

I am working with my Nissan 300ZX and want to remap some of the fuel and
ignition settings having raised the boost pressure and fitted a larger
intercooler.

The module is a JECS unit that has two processors, both are 68 pin
devices one marked with " HD63C03YCP" the other " HD63140CP". The Rom I
have replaced with a 256 Eprom so as I can Access the code.  

Does anybody have any idea who manufactures these processors and any
software that can help with the remapping.

	Thanks Roy.
