Sensor voltage modifier

Here is how Harley Davidson "richens" up their sensor.

This is the exact opposite of what an EFIE does. The EFIE adds voltage to make the mix look richer to the ECU, which will then lean the mix.

The circuit on that link lowers the voltage, makes the mix look lean, and the ECU then richens the mix.

As a note, if you want to run a vehicle richer, just hook the EFIE up backwards to the signal wire, and you'll get an adjustable richened mix.

Correct- they are trying to give the HD more power. I believe their afr was 14.3.
