Due to a crush of popular demand, OK, both of you, I was able to get an unflashed 2013 ECM so I could determine what just swapping cams would do.
Thanks to pekingduck for the loan of the ECM.
Unfortunately, it would appear that the limiters are different. Running in 3rd the limiter was coming in at what appears to be 5800 rpm. The lean spot at 3500 rpm is far more exaggerated which appears to cause a loss in power.
At about 3650 rpm it richens up and power and torque bounce up above what my stock setup was.
This is not apples to apples, I should have just replaced the cam, tested, then flashed. I suspect that for whatever reason, the original programs may have changed? I know when I was working at a GM dealership we would occasionally get a notice to do an upgrade flash on certain vehicles. Maybe Honda made some midyear changes.
It does appear that beyond 5500 rpm power seems to be the same as original.
I do know that with the flash and the cam swap it runs great.
Heck, it ran great before! But I really like the torque bump and less buzz.
Sorry, Josh, the dyno man didn't know anything about a run file, said he hadn't dealt with it. I know he dyno tunes Harleys (don't tell anyone), and the sportbike guy across town might have been able to, but I got what I got.
The wheels are already off for new tires and I am swapping sprockets for longer distance cruising this summer.
pekingduck, I will get your ECM back post haste.
