Harley Davidson Magneti Marelli Fuel Injection Settings
This video is about setting the Throttle Position Sensor and cold idle motor of the Magneti Marelli Fuel Injection System used on some Harley Davidsons from 1995 through 2001. First of all, let me just say, "if it ain't broke, don't fix it." If your TPS (throttle position sensor) is not defective and has not been moved from its factory setting, DO NOT TOUCH IT! I have experimented with changing the settings of the TPS on a few fuel injected machines over the years and thought this system to be no different. It is, in that it is very sensitive in how far it is moved. It doesn't take much movement one way or the other to make it way off from where it should be for a good running motor. I even had it so far off at one point that it tripped the check engine light on a test ride! There's a reason the TPS screws have some sort of epoxy in the heads of them to keep us from tampering with them! I decided to find the info on resetting it to factory specs (with a minor change to the cold idle setting) and doing it myself. So, that being said, if you absolutely HAVE to wrestle with this beast, maybe this video will help you understand what you are up against. I will tell you it was difficult to keep the TPS still while tightening it down while watching the voltmeter. Anyway, thanks for watching, comment as necessary, especially if I left anything out. Here are the instructions I found on a forum to tell me how to do this with some minor changes to help explain the process a little clearer: Unplug the ISC (cold idle motor/solenoid connector) actuator connector. Back the cold and warm idle screws out enough so they're not affecting anything (leaving a gap between the screw ends and the surface they normally press against to control the idle speed). Backprobe the TPS connector (stick a small sharp pin into the wire to touch your test meter probe to) at the GY/V wire (the grey/violet stripe wire on the right side facing the connector). Connect your volt meter to the probe and ground it to a GOOD ground. With the bike's ignition on (bike not running), loosen the TPS screws enough to turn it side to side and adjust until you get the 0.275V figure on the voltmeter. Lock it down there while watching the voltmeter reading. Next, adjust the cold idle screw by turning it in until you raise the voltage reading to 0.65V. (Using the procedure in the manual will almost always produce a cold idle that's low, if you see an older manual). Power off the bike. Re-connect the ISC (cold idle motor/solenoid connector) actuator connector. Remove the probe pin and voltmeter and make sure area is safe to start the bike. As the bike warms up be ready to adjust the warm idle screw by turning it in to keep the bike from stalling as the cold idle motor/solenoid relaxes the throttle until it comes to rest against the warm idle screw. Adjust the warm idle screw for the bike to idle at about 1000 rpm's. The warm idle screw can be reached through an access hole in the plastic air filter backing plate in case you need to readjust it after everything has been put back together. Bonus Tip: I covered the TPS wires with clear nail polish around the area where the pin was pushed into the wire, both sides, all the way around, to protect the wire from the elements.
