FE570 Fuel mapping

Hi guys, I own a US spec 2011 FE570 and I'm trying to find a source to correct the lean fuel mapping. Bazzaz apparently has discontinued their FI programmer. I'd be thrilled to send my ECU off to be re-mapped if I could find a source to do this. Any help would be appreciated. I'm open to buying anything that actually corrects the lean fuel condition.
Thanks in advance for any help.

I'd recommend reaching out to 2WheelDynoWorks.

They've tuned several of my bikes over the years.
(incl...KTM's, Husky, Triumph Bonneville...some by overwriting the stock ECU, or by piggybacking a PowerCommander)
Hands down, one of the best tuning businesses out there.

(disclaimer) I don't work for them, or have any sponsorships, etc, from them.

There are "piggyback" tuners available that intercept the stock fueling signal and either lengthen or shorten the input to the injector, based on throttle input. JD Jetting and EJK both offer the same/similar product with different labelling. The tuner and interface is identical, but they each suggest different initial settings for aftermarket, less restricted exhaust. Search the forum for FI tuners and mapping options. I have personally used the JD Jetting tuner and have found noticeable changes in engine character based on settings. EJK seems to have more online information regarding Husabergs. With all zones set to "3" you are running stock setting. Each of 7 zones/parameters can be tuned between 1 (leaner than stock) and 8 (richer than stock).
