Works on an '07 .. I wonder if it will work on an '08?
One wireto the battery ground, and connect harness to the injectors. ECM doesn't know it's there.
Easy setup .. Comes with a couple 330 ohm plugs... Got mine under the seat of both my Electra Glides.

Unplug the O2 sensor connectors.. plug in the 330 ohm resistors... No more closed loop.

I think the injectors were changed somewhat on the 08 to go with the new 50mm throtle body, but they may still have the same connection.

I doubt if anyone has done any fuel management to the 08's yet, HD hasn't even shipped out the SERTS or offered a download yet. Mid September and you will see the setups being done.

I'm not usingmy sensorsand the engine runs much cooler.. and has much more pep.
This by all means isn't the right fix, but it gets me by for now.
I'm waiting for another solution to the heat issue. I read the pamplet inserted into the summer edition
of the Enthusiast. Very thought-fully written. The person that wrote it .. said big bores make more heat.
I have been around large bore v-twin japanese bikes. They seem to run cooler then my TC96? I wonder
what AF ratio they are running? Maybe it's all in the timing?
