In trying to diagnose my current FI woes, I've been spending a lot of time with the MPS and the ECU (see post:http://forums.pelicanparts.com/showthread.php?s=&threadid=98920&perpage=20&pagenumber=2.

I noticed that prior to some of my testing the knob on the ECU when turned CCW (leaner) would cause the idle to increase. While turning CW (richer) would cause the idle to decrease.

Somewhere in my testing of the last several weeks it has switched. CCW on the ECU now decreases idle, and CW increases. Since my FI problem is related to fuel mixture, this doesn't completely surprise me, but I'm wondering how it came about.

Any ideas?
