megagame - any update. Have been following and enjoy what you are doing. May need to do some upgrades to my Spyder down the road, but my '85 Gold Wing Limited Edition FI model ECU replacement project (turned into a CFI system upgrade) has kept me busy. Don't know if I mentioned, but I am using the Speeduino v0.4.4 interface board with an Arduino Mega 2560 microprocessor. Very impressed with it to date. Doing road trials at this time. Have turned this old GW FI system into a more modern one with the addition of a WBO2 sensor, new coil driver (Bosch 211), sequential fuel and ignition, COP units, VR crank and cam shaft sensors sensors replaced with Hall Effect sensors, upgraded fuel system with an adjustable FPR, and lots of wiring changes. Honda used two camshaft sensors in its design, know why, but have had to take one out. Learning how tuning software works, Tuner Studio and MegaLogViewer, has been a steep learning curve as well.
Enough about mine, let us know how your's is progressing. Cheers
