Rides smooth at hwy speeds, throttle is responsive with the fly by wire system. The only thing is the rear cylinder will not cut off in traffic. I had Harley check it out and the bike does not have that feature. I installed Love Jug fans and the bike does not go below 8 lbs of oil pressure sitting in traffic. Highly recommended item. TACOMATruckin98. drive by wire = throttle plate is not mechanically controlled ( throttle plate opening/closing controlled by a cable). it has a sensor on the gas pedal to determine gas pedal position, then the signal is relayed to the ecm/ecu. after that the ecm/ecu sends a signal to open/close the throttle plate via a small motor on the Causing the throttle to be stuck at 50% because that's where it was when the PCM rebooted and it now thinks that 50% is 0%.. That's just one of a hundred scenario's that makes this insane. If you're going to run throttle-by-wire with a megasquirt you might as well setup brakes-by-wire too. $0.02. What is Throttle By Wire aka Fly By Wire you ask? Take Off the Old Handlebar & Remove Old Cable. At the end of your throttle side of certain handlebars made specifically for most 2008 up big twins, there will be a castle looking end. I nserted in that end is a tube with a gear that locks into the castle part of the tube. Accelerate-by-wire or throttle-by-wire, more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric motors by Blue/green wire on twist grip sensor to blue/green wire on ECM (pin 59). Brown/orange wire on twist grip sensor to brown/orange wire on ECM (pin 50). If the reading Open or "OL" is present on any of these six wires, there is a break in the wiring. Figure 4. The twist grip sensor. Related Discussions. Fly by Wire Throttle Failure - HDForums.com Throttle-by-Wire. In 2005 Ford introduced the throttle-by-wire system that actuated the throttle plate using an electric motor rather than a traditional cable. The gas pedal is an electronic device that sends signals to the throttle motor via wiring. This means provisions need to be made in your swap to accommodate the throttle-by-wire gas pedal. The first component of the 'X-by-wire' system introduced to the market was 'throttle-by-wire' from the late 90s to early 2000 (Anwar, 2009). The electric-hydraulic breaking system, as a way of Paired with the throttle-by-wire system, a new slipper/assist clutch also ensures that the lightweight naked bike doesn't put eager noobs in a bind. In addition to delivering a feather-light On a fuel-injected engine the throttle body is normally located between the air filter and the intake manifold, and is connected to the gas pedal mechanically with a cable, or electronically by wire. When the driver presses the pedal the butterfly in the throttle body pivots to let more air flow into the manifold. XocQy5.
