Cannot find info on how to socket/upgrade EPROM on this ECU. There is plenty of info on how to install Nistune Board, however only want to swap EPROM for injector upgrade

There might be some info on older pages. Like this for example http://redz31.suomiz.net/pages/fuel/romulator.html

and yes, it's about installing the NIStune board, but it shows the EPROM for the 84-85 for fuel & timing maps.

Thanks for your reply.

However , the instructions only relate to connections from the Nistune Board to CPU chip etc - not an EPROM. It appears that a replacement EPROM can be only loaded to later i.e 88ECU which are single EPROM.
