> Wow, can't get over the group interest in this topic!  You bet I could use
help<G>
> There must be a bunch of guys interested in applying DIY-EFI conversions
to aircooled motors in aviation, car and bike applications.
> The type of vehicle is not as important as sharing the information.
> I have a completed Polliwagen homebuilt airplane and have started
rebuilding a Corvair with a Rinker redrive. Initial plans were to install a
Zenith sidedraft carb, but this step may be skipped to go directly with EFI
as I have most of the parts.
> I have 2 ECUs from a 1990 Geo Storm.  I understand this ECU or variations
were used in other 3, 4, 6 and 8 cylinder applications.  My expertise level
is strictly mechanical so be patient with my low level of electronics
understanding.
> The ECU box is coded  86501 J100699333*    How can the code mask be
retrieved?
> Big chip on motherboard  -  u7  185  16141356  KQEXB8942C
> Other chips:   34492 Delco        16045980 Delco    16045580 Motorola
34993_945D3_466        2 of 519K_8937_9057_16079435
> Duh, now which one of these is the prom?  All chips appear hardwired as in
soldered.
> The loss of Steve Parkman was tragic, and his business partner suffered a
very severe disabling stroke, effectively closing down SWAG Aero.  I don't
think anyone else is carrying on the business. There was a tremendous amount
of interest in the system since for $100 one got a conversion manual
including reprogramming of your GEO ECU for specific applications.
> The SWAG  EFIs were reliable and effective if properly installed.  From
what I understand, Steve's crash was caused by a failure of his own design
chain driven reduction drive.  The prop sheared off shortly after takeoff,
and his VariEze homebuilt crashed in quite rough terrain.
