[Ducati] Ethanol blends

[Wright, Dirk]

Dang. that's awesome! I wonder how much one of those things costs? I can't find an online dealer with prices, not that I'm going to be running out to buy one of these things....

The Motec fuel injection system for motorcycles has a provision for an O2 sensor (including wideband lambda if you want it!!)  and is fully programmable for injector pulse width, ignition timing and dwell, speed, traction control, etc.

See it at:  http://www.motec.com/products/ecu/m48ecu.htm

Only a few Ducati's have O2 sensors, at least the one's sold here in the 'states. The only ones that have them are the ones that catalytic converters on them. I suppose Ducati had to put an O2 sensor on those to make sure the cat didn't melt and/or otherwise overheat. Still, an O2 sensor on an FI engine is a great idea, with or without a cat. I just wish there was an aftermarket ECU available that accepted an O2 sensor input. The oem ECU has static mapping, from what I can tell, which is a pain to deal with really.

Not sure about ethanol, but we used to run our methanol bikes a lot richer,
like 5x the volume of fuel compared to petrol.  Engines ran cooler and made
more power.

Ethanol should have more available carbons for oxygen than methanol but not
as many as regular petrol, so I would think that you could experiment with
going slightly richer.  I would also think that the oxygen sensor in the
exhaust should pick up excess O2 and cause the mixture to richer
automatically.

So, all you should notice with an efi bike is slightly (maybe 5% ?) heavier
fuel consumption.  I wonder if this happens in practice.

I wonder if there is a way to optimize ignition or valve timing to get
better performance out of this stuff?
