I assume you want to do "Engine Learn" If you want to set low idle, start the machine and rotate the throttle knob to minimum. The out put voltage from the EC sensor should be 2.5 volts. The controller considers 2.5 V as "idle position". Adjust the lever arm on the EC motor to achieve low idle RPM while at 2.5 V. RPMs also can be tweaked using the Palm based Dr ZX. This changes the voltage that the controller considers as idle voltage. Example, 2.3 V. This eliminates wrenching on the linkage to change the idle RPM. If you want to do the the high idle side, pull the fuse cover (in the console to the rear of your left elbow while sitting in the seat) and find the engine learn switch. (Small toggle switch under a "C" shaped cover.) I think it is a 3 position switch, back, center, and forward. With the engine stopped and the key off, flip the switch towards the "E" stamped on the "C" shaped cover. (Forward I think) Turn the key switch on for 5 sec, turn the key off and turn the engine learn switch off. (center I think) You are done. The engine learn allows the EC to "find" the injection pump's hi idle stop bolt and stores that voltage as the hi idle position. Auto idle etc. is "prorated" from 2.5 V to the stored V of hi idle. Good luck.
