GM ECM Flash programmer

[peter paul fenske]

Hi Ken

I have been looking at the 8051 PCM.
Aldl communication is not difficult.
Just use the RS232 interface and software that was posted
to this net previously.

However to up load and download eeprom contents is a wee bit more
difficult. But similiar to aldl comms

email me if interested
