i share project working in free time: name fuelino. fuelino fuel injection controller , data logger designed motorcycles equipped efi (electronic fuel injection). regulating fuel injected in cylinder, possible increase power of engine. if modification optional, if have stock engine, becomes mandatory if change components of motorcycle, such exhaust pipe, camshaft, cylinder size (bore kit), air filter , on. fuelino helps adjust injection timing, achieve proper stoichiometric air-fuel ratio maximizes output power of engine, or minimizes fuel consumption. compensation applied original signal timing, in %, depends on throttle position sensor signal (if connected), , engine rotation speed (calculated measured time period between 2 consecutive "start of injection" events). the project open source, can find more info @ following links: http://www.monocilindro.com/fuelino/ http://www.monocilindro.com/category/electronics/fuelino-project/ the following image shows how connec...
