SV: auxiliary fuel control that modifies factory ECM pulse widths

[Raymond Brantley]

Not to knock Racelogic Julian was really helpfull, but the software/hardware
was VERY expensive. I ended up selling mine to someone at Hypertech. Then
just opening up the binary file in Hexedit and looking for maps and
functions :>)


Thanks,
Raymond

The other way around - it looks to me like Intel used the EECIV CPU to
make the 8096/80196 family.

In other words, Racelogic doesn't know where the maps are.  They leave
it up to the user to find the maps - via trial and error using some
simple brute force software.

The EEC mailing list archives contains a lot more info.
