I had a brain fart the other day, and ordered myself a Power Commander V. Who knows why,
because my bike is running beautifully, and I really don't need the extra power, but I
have this curiosity to see how this auto tune thing works. I ordered it from the Bike
Doctor here in Perth, and the Australian importer, because Dynojet won't warrant or support
the units if you bypass their dealers.
It turns out that I appear to be the first person in Aus to have bought one through the
local importer, so I am breaking new ground here. They had them in stock, so I got the
units overnight after I placed the order. I spent today doing the mechanical installation,
and tomorrow I will re-assemble the bike, program the units, and see how it works, good I
The first problem I had, was that my computer with Windows Vista, absolutely refused
to load the program disc. I switched off the firewalls, virus protection, user account
control, and everything else I could think of, but it wouldn't have it. Fortunately, I have
and old computer with Windows XP, and that took the disc no worries, so I will use that.
The main connectors into the EFI. I also had to block off the air injection pipes into the
exhaust system. When I make up some proper plugs, I will be able to get rid of all those
air pipes and air solenoid on top of the motor.
The hole in the exhaust where the old O2 sensor went.
New O2 sensor installed. I had to file that bracket to make room for the cable.
New connector for the O2 sensor, ugly great thing.
Units in the tool tray.
Power cable for the Autotune unit, spliced into the tail light circuit.
