I bumped into ECUnleased today. They offer flashed to ECUs that remove/fix limitations that are factory programmed into the ECU.

The good thing about this is a piggy back device is not required, and the changes are direct to the ECU. In addition to fuel changes, timing changes, and restrictions are removed/fixed.
The guys who do my tuning offer this service and seemed pretty pleased with it so far. The cost is $449 is a pretty good deal considering the cost of a PC3 and a dyno session.
From what I understand the flash can be loaded and the bike can be dyno tuned and further refined. Also once the flash is created it can be reload if need be with at no additional cost.
I'm sending my FZ1 ECU to AF1 Racing to have the work done. Turn around time is about a week and half with the mail.
Here's the stuff they can tune:
ECU Modifications – (Optional per customer request and application)
* Remove Factory Timing Retard
* Remove Throttle Restrictions
* Increased Idle
* Increased Rev Limit
* Remove Speed Limiters (Gear Dependent)
* Reduce Excessive Engine Braking/Improved Deceleration
* Improved Throttle Control & Reaction
* Remove Injector Shut-Off on Deceleration (Bye bye FCE)
* Eliminate Factory “Error codes” (ex. exhaust valve, steering damper)
* Improved Fuel Maps
* Improved Ignition Maps
* Injector Phasing Adjustment
* Velocity Stack Switching Adjustment (Variable Stacks Only)
* Race Fuel Mapping Accommodations
I would think that this would fix the crappy FZ throttle for good.
