I'll repost what I put up in the Tuono forum:


Top blue and green lines are Gabro (tuner from Italy) V5 (EPROM, based on 03' RSVR ignition map) + PCIII, Evo (Evoluzione) Header, Evo Filter, Evo wires (non-resistor) and Telco slip-on, 2 best full HP runs from the day.

Upper yellow-green line is Evo Filter, Telco slip-on, Gabro V2. Red line is Same but Gabro V5 map.

Bottom dark red line is stock US ECU, Evo Filter and Telco slip-on.

Note: The lower 3 are from a different day, but the same dyno. Uncorrected HP on the final day was 124.14 and 77.43 ft/lbs, but the dyno room was 56F vs 79F.

Keep in mind also, my bike ran unusually rich prior to mapping. I was getting good freeway mileage, but around town I was getting ~25mpg.

cool..thanks Chris..it was not easy...that thing was all over the place!! most shops will only show you the 100% TP (wfo) charts cause they dont spend the massive time to get the part throttle right...ASK FOR A PART THROTTLE RUN! We (EDR) dont give it unless someone asks, cause it waste paper and 99% folks will be confused at what they are looking at.

When I raced novice at Spokane and Seattle back in 99', I had a lot of problems with the hairpins becuase my GSXR's carburetion was so erratic at partial throttle, and low speed corners exacerbated the issue.

On the Tuono, the partial throttle issues make the bike difficult to ride in stop and go traffic. I had to compensate by slipping the clutch or by trailing the rear brake at times. It also destroyed my gas milage during commutes.

I'm not an expert in tuning, but I can't imagine why any shop wouldn't focus most of their energy on partial throttle fuelling, considering how critical it can be for control in corners. WOT peak power is great, but how often do we really use it on a streetbike?
