ECM Test Bypass
« on: May 11, 2020, 02:10:36 PM »
Hello,

As a potential purchaser of an Eagle and just curious, what exactly does the ECM Test Bypass do and why is it regarded as such a benefit.

Thanks in advance.

The ECM Test Bypass (also called The "Neuter Bypass") takes the computer out of the circuit. I don't know the EXACT details, 2 of the last three Eagles I've bought already had it done & I didn't mess with it. I know it is (at least partially) for the feedback carb..
