Now I done it... (general discussion)

My modersickel is new enough that it has an "ECU" or Engine Control Unit...a computer.

It controls all manner of things including the fuel injection, the "throttle by wire", traction control, ABS brakes, cooling fan, etc. etc.

One of the common complaints about the bike is snatchy fueling and excessive engine braking. It IS a little difficult to control the throttle smoothly, especially at low speeds. This is because, apparently for emissions reasons, when you back off the throttle the injectors cut off completely. LOT of engine braking. Opening the throttle back up without chain snatch takes some practice.

So, there's a company out in Warshinton that will "re-flash" your ECU to correct these things and will also change several other settings to your specification or a custom flash if you've gone to an aftermarket exhaust or suchlike.

They're having a sale...

I'm going to have their basic stock flash done which will cure the snatchy throttle issue and also have them remove the electronic speed limiter and lower the "fan on" point to 200°. Even in Maine, the bike will go north of 220° at a stop light in July.

Fortunately, there was a tutorial on how to get to and remove the ECU to send it out to be reflashed. Sufferin' Teapot, there's a lot of plastic on that bike.

Upper Tank Shroud. (4 fasteners and 2 rubber bung mounts)
Rear Tank Shroud. (4 fasteners)
Lower Tank Shrouds.(3 fasteners, a bung mount and some velcro on each side)
Turn Signal Panels.(3 fasteners, an electrical connector, a bung mount and a clip on each side)
Rear tank mount bolts.(2 fasteners)
Front tank mount bolts.(2 fasteners)

Just so I can lift the tank up far enough to undo two multipin connectors and slide the ECU out. And I cheated and just propped the tank up while removing the ECU instead of unhooking yet another connector and two hoses from the fuel pump and taking the tank all the way off.

Almost makes me want to go back to carburetors. Almost...

Hah! We ARE taking our country back. Suck it, Liberal Commies!
