Harley Davidson Magneti Marelli Fuel Injection Settings
This video is about resetting the Throttle Position Sensor 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.





Como Funciona a Injeção Eletrônica de Combustível
A injeção eletrônica (português brasileiro) é um sistema de alimentação de combustível e gerenciamento eletrônico de um motor de um automóvel - motor a combustão. Sua utilização em larga escala se deve à necessidade das industrias de automóveis reduzirem o índice de emissão de gases poluentes. Esse sistema permite um controle mais eficaz da mistura admitida pelo motor, mantendo-a mais próxima da mistura estequiométrica (mistura ar / combustível), isso se traduz em maior economia de combustível já que o motor trabalha sempre com a mistura adequada e também melhora o desempenho do motor. O sistema faz a leitura de diversos sensores espalhados em pontos estratégicos do motor, examina as informações e com base em outras informações gravadas em sua memória envia comandos para diversos atuadores espalhados em pontos estratégicos do motor. Esse procedimento é efetuado varias vezes por minuto com base nos movimentos da cambota.

DIY Fuel Injector Cleaning & Repair
This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause. Tech info: The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it. I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary. In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at. This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.

Why Fuel Additives Don't Work The Way You Expect
http://www.fueldirect.ca The Consumer The Goal - Save Money on Fuel Cost The Corporation The Goal - Save Money on Fuel Cost, Maintenance and the Bottom Line In Order To Reinvest 2 Completely different markets but they both has common goal - To Save Money On Fuel Cost. Well there are many fuel additives to choice from but which once can you trust to used that will not leave something behind. While most additive will work they tend to use harsh commercials and or petrol based distillates. But in this video are going to share with you a brands ability to burn clean. Clean means no left over residue once it's introduced to the burn process. Take a look and name a winner. Xp3 Fuel Enhancers are not your everyday fuel additives, nope it's more then that...it's a fuel enhancers that was produced to burn clean without increase toxic emissions and without the use of Petrol distillates like aromatics, Naphtha or Alcohol.

MAP Sensor Quick-Fix
GET SOFTWARE NOW! http://www.autodiagnosticsandpublishing.com/Software_Catalog.html MAP Sensor Quick-Fix The MAP sensor, is a 3 wire sensor, that measures intake manifold vacuum. The ECM,uses this value,to calculate fuel injection open time. To test the MAP sensor, and circuit, do the following, with MAP sensor disconnected. 1) First check the ECM circuit, by checking for 5 volts, at one of the 3 MAP sensor wires. 2) Check sensor ground. Check voltage between battery positive, and one of the MAP sensor wires, either or is fine. 3) Reconnect MAP sensor, then backprobe center wire, should have under 1 volt. That's it for circuit check. Then, while probing on center signal wire, start engine. If engine won't start, due to no injection, then it's not the MAP sensor. MAP causes stumble and rough idle, not no start. If no start, use the No Start Trubleshooter Software for extended help. Finally, with MAP sensor, and voltmeter connected, remove MAP sensor, plug a hose to it, and suck on it. You should see voltage fluctuating. If so, then engine no start is due to another reason. If engine starts, then use the waveform database, to determine proper idle running value, and fuel trims at plus or minus 10%. That's all for the MAP sensor quick fix.
