AUX. MEM. PORT

[peter paul fenske]

Hello to everyone:
Am just wondering if anyone besides GM has tried to acess the
auxiliary memory port on the 730 ECM. It appears that by pulling
one pin low on the test connector , ported memory driven by a PC
could be attached. This could allow custom fuel calibrations ect.
This is a little bit easier than borrowing very very expensive
eprom emulator.
Also wondering if anyone played with redundant fuel device.(RFD)
Also can someone confirm that the extra two chips in the calpak
are resistor networks designed to drive the RFD. I always thought
that the software which hooks at 6000 was located here.
Well tnx for help
GL all: peter
