OK, so here we go again. :-[

 Power commander tables are built on throttle position sensor inputs.  That's where the problem comes from, because at low throttle opening the engine IS being directed by a speed / density table from the map sensor , and then the power commander is trying to override the wrong table. Probably the best way to get out of problems with the power commander is to zero out the maps and make no corrections below probably 30% throttle so it doesn't try to override the fueling generated from the map sensor.  Steve

Steve,
  To make all of this simpler for us just be straight up and admit it's all PFM.  :motonoises:

No, it's not. Don't know where you saw THAT, but it's clearly $75.

I meant for the entire Dyno Tune that was included.

Roger that. It does seem like you get quite a bit for $75. But I think I'd rather get all the testing, tuning, and refining that has gone into Steve's package, which would seem to be the most likely to provide the across the board improvements I'd like to see.

Like I said, I paid over $300 for a Power Commander on another bike, and it was only marginally effective. I spent a lot of time screwing with it, trying different maps, making my own, and finally settling on one that another guy that had the same bike with the same setup had created with dyno pulls and let me have. It DID turn out to be the best, but it was a gas hog and only made a modest improvement in the "seat-of-the-pants" department. It wasn't worth $300.

Hello to all.  New poster here with a question, while we are on the subject.  Just bought my first Concours (2017) this past June.  The first mod I did, even before I had finished breaking it in, was get Steve's evolution flash, which I am very happy with.  It addressed all of the issues and frustrations I had with the Concours (namely jerky throttle response and lack of low end torque).  The 10-15% increase in gas mileage (as corresponding increase in range) was just a bonus.  My previous bike was a 2011 Suzuki 1250FA.  Even though it had only 98 HP, it sure felt a lot stronger, I guess due to different tuning, an engine with a longer stroke, and the fact that it was 110 pounds lighter.  Anyway, my question is in regards to the o2 sensors and the ECU flash.  I unplugged them as originally instructed, though I understand this is no longer recommended, since as Steve explained, it was only done to diagnose faulty grounding issues.  My question is, would there be any benefit to plugging them back in?  Or does the ECU flash completely override input from the sensors anyway?  I believe I read in a previous post that one member swore that the bike seemed to run even better after plugging them back in.  Is this logical, or not?  I like to ride up into the mountains in higher elevations sometimes here in Virginia and perhaps input from the O2 sensors might offer some benefit??  Also, I have a little concern about the open O2 plug wires being exposed to the elements, even though I have covered them with electric tape.

Freddie, they're already off, just leave them off. The system is shut off anyway. Steve

Thanks.  That answers my question.
