Double Thumbs-Up on ECU Reflash for '04 Breva 750cc

I installed the ECU that Todd ("GT-Rx") reflashed for my 2004 Breva 750cc. After filling the tank, I took a 150 mile day ride with it. I fell in love with that motorcycle, all over again. The bike runs fantastic. I was immediately impressed with the new found tractability:

  • Started quickly with no spitting on cold ride off.
    Tip-off from closed throttle to WOT, and all points in between, is perfectly smooth.
    No blubbering at lower throttle openings, or after shifting gears.
    Sustained "traffic cruise" at 25 mph with barely open throttle was smooth, with neither misfiring or bucking, and
    No stumbling or hesitation at all on subsequent acceleration - or anytime else.
    My ride included elevations from 5,000 ft to 7,500 feet. Perfect fueling and perfect manners the whole way.

Previously, the engine would "fade" slightly from time to time at highway speeds as if the ECU was briefly unsure of how much fuel to feed it. Maybe the O2 sensor was sending flaky voltages. Who knows? The important thing is that there is no more fade out!

And the final accolade:

After such a full-spectrum improvement I was fearful of how bad fuel consumption might now be. More good news: 150.9 miles only took 2.9 gallons to re-fill. That calculates to 52.3 mpg, and that ain't bad. Oh yes, that included playing squid in the mountains with some guy performing unnatural acts on a GL1800.

Double Thumbs-Up to Todd's work. So worth the price paid.

Thank you
