Default PC III hesitation off idle on 07 models

The new firmware is a hit!
For anyone who thought that there was a tuning problem - it wasn't. Installed the new firmware and now the problem is not present. Fully warmed up the bike, duplicated the hesitation. Uploaded the firmware and could not duplicate the hesitation at all. Not sure what was changed in it, but it solved the problem. DynoJet has restored my faith.

This was on the 07 Street Glide, Rineharts and Big Sucker. Problem existed since January and could not be tuned out. Bike was run for 6000 miles with the issue.

I installed it a few days ago but didn't try it out 'til today. My hestitation was very minor, maybe a few times per week and barely noticeable, mostly something I heard rather than felt. On today's ride the bike ran perfect with no hestiation at all. Others have reported that this FW update has fixed their hestiation problems, so maybe this is, as you say, a hit.

You can get it on www.fuelmotousa.com and click on "dynojet technical info" on the menu. There is a link about halfway down the page.

Just flashed to the new firmware and it seems to have cured my stumble problems as well. I have an
'07 FXSTC.

I went to the Dynojet site and saw there are TWO firmware updates

One say FUEL Firmware update 2.1.2
and the other says IGNITION Firmware Update 2.1.2

do you need BOTH firmware updates?

Looks like Fuel Moto has 2.2.0 Hmm going to wait until Monday to Call Dynojet and find out which is the proper firmware and what it fixed (release notes)

spoke with Dynojet and there is a version 2.2.0 which is in BETA still. Looks like Fuel Moto has released it, but Dynojet has not officially released it on their website.

It does address the hesitation from idle only. The tech said he was not sure when the 2.2.0 would be put up on the Dynojet site.

the 2.1.2 firmware is the one for the Harleys now. the 2.1.2 Ignition is for sports bikes.

My recommendation would not be to update firmware unless you are experiencing a problem. Updating any firmware "just because" is never a good idea. If it aint broke, don't fix it.

I applied this to correct my pinging problem (recommended by DJ). It did NOT correct the problem. The new firmware is not compatible with the Accelerator Pump utility. The utility will not see the PCIII. If you have it turned on prior to installing 2.2.0 it still is still activated in the PCIII. But to turn it on or off you must reload the 2.1.2 firmware, toggle the Accel Pump and then reload the 2.2.0 firmware.
