I've been researching building a DIY O2/Lambda sensor eliminator and came across the following for the Super Duke:

A O2 eliminator should trick the ECU into thinking it is in stoichiometric and break the closed loop cycle. This is useful on the 390 as if you are running a piggyback like the PowerTronic it won't work properly when the ECU is in closed loop mode (below approximately 4-5000 RPM).
The trick to a DIY version is just getting the resistance correct to feed the ECU the correct voltage. I'm guessing that the Super Duke version discussed above is a good starting point but will likely require a bit of reverse engineering on the 390 to get the precise voltage.
In theory I would imagine you could go even fancier and attach a POT instead of a static resistor and you could "tune" richer or leaner.
I'm in CA and still don't have a bike yet so I can't test any of this stuff out. Be interesting to see what others come up with.
