ECM reflash???? trouble?

Has anyone been dissatisfied with the reflash? I am right now. I have tried it out for over 700 miles and lost 1 to 1.2 miles per gallon. I feel a loss of power up to 3000 rpm, but have felt a big jump in power over 3000 rpm. Trouble is, I wanted more power up to 3000 rpm and more mpg. Going above 3000 rpm, I am over any speed limit in Ga. Has any one else had this? ? ? I called Don and he said he was going to look up records of my ECM and see if he could tell what was loaded. It has only been three hours but I am waiting for his call back.

This is mixed,not aggressive riding with the #3 tune,how hard are you riding? what is your MPG?


80 miles 1.8 gallons = 44.4 mpg

95 miles 2.2 gallons = 43.1 mpg


69 miles 1.6 gallons = 43.1 mpg


121 miles 2.9 gallons = 41.7 mpg, more traffic and stop lights then first three rides

I think you may be the first one to have a 2006 reflashed. It's possible that the original maps in your bike were different from the 2012 maps that Don base-lined from.

By the way, Don has always offered to reflash any ECM back to stock for free if you aren't happy with it.

I spoke to Don today and almost no changes were made in the mapping on the 06 below 3K rpm. The changes were made to the maps on 2012/13 bikes to make them mimic the 2006 map in that RPM range, specifically for fuel trim adjustments. It may be that since the bike now makes more power now above 3K, that it just "feels" like it lost power down low because there is such a dramatic change or "hit" above that rpm range. Don is also going to overlay the data from your original ECM with the changes and double check them today. He also suggested that if you could bring him your bike and put it on the dyno, he could do some further testing for you.

Don sounds like a good guy that wants to make things right.

That is a mild understatement. Don's name and rep. means more to him then having an unsatisfied customer.. He will do whatever he can to make your bike right !

This is why it is a better idea to have an inline manipulator instead of flashing some predetermined map onto your bike. Just as reference, all the Honda race bikes that get remapped require going lean between 2800 and 4K. I'm sure there are other such anomalies in regards to different engines in Honda's line up.
I would definitely take the guy up on bringing the bike to him to try to create a proper map for "your" bike.
BTW this, "Seat of the pants stuff" is BS. You can advance your timing to make it seem that it has much more, "seat of the pants" power because it will hesitate for just a bit, then come on like a bat out of heck. But if you actually time runs, you will find that you lost out. Seat of the pants is for harley riders, not motorcyclists.

Well even without the DYNO chart Don did of my poor departed WING, showing gains most of the way up from idle.. My seat of the pants feel was wonderful and gas mileage improved enough for me to want to keep it.

Don did call me back and said he would do what ever he could to make me happy with my bike. We are about to leave on vacation, he said to call when we return. He said I could have carbon build up that will not let the new flash work right. He said to try a little higher octane to see if that helps. I told him I would run a load of sea-foam through it also and see how that works. I will try almost anything to get it to work like everyone else's before I send it back to Don. Fred, you are right. He want's everyone to be happy. Thank you Fred for talking to Don with ideas. I hope everything works great by the end of our trip.
