TuneECU and Dyno in Las Vegas, NV

[JSHRAM]

Hooray! I have been going to this shop for several years and always loved the professional expertise there. Dale, the owner, agreed to help with my Tune ECU. So, here's how it went. He ran the bike on my chosen map and tracked where it was running lean/rich. Then I saved that map file with a new name on MY computer and he tweaked it right on my computer, I then saved the file, and downloaded it to the bike, and he'd run it again.. we did that about 4-5 times.

So, until he figures out TUNE ECU and gets it into his dyno computer (he's very protective about his Dyno computer for good reason) you'll have to bring you own lap-top and your own cable..

But the GREAT news, is that Dale will help us Tune ECU folks in the US South-West! WOOT!

I figure the more folks that ask to use Tune ECU, the more motivated he'll be to get it working on his computer, so go on in! Price was right too.. he charged me $100 for the session.... I just had to be patient as he did business in-between runs. .no problem. Glad to be patient for such great service. Besides, he was patient when I was fiddling with my computer/program. Best to make sure you're up and running with that before you go in....

Good news. Vegas is only 7 hours from me. How does your bike run after the tune?

Fantastic! Much smoother, easier transitions through throttle and no decell popping anymore.. plus it isn't lean! yesterday I did 650 miles around through Page, AZ and the North Rim of the Grand Canyon... zero issues... burns a little more gas now, but that's how to not make it lean...

Please post your dyno for us to see.

Awesome! Sounds exactly like my experience! Enjoy!

These observations appear critical but they are intended constructively and not argumentatively

So the plot is a wide-open throttle (max HP) plot
A/F is right at 14 (pretty much exactly - flat line) up to 80mph (rpm would have been more useful) which almost suggests it was in closed loop control over that part of the curve (but then again it can't be if it was WOT);
then from 80 + it certainly does look lean - at least where making power is concerned.

You mentioned it was smoother through the rpm range but that you only did about 4-5 iterations
Honestly, that is nowhere nearly adequate to dial in the whole map - maybe just the wide-open throttle map - and the $100 is indicative of that (and a more than fair price for a WOT tune)
But that is not going to do much for your mid-range performance (although maybe that's more the area he was focusing on?)
To do a thorough tune, you really need a pull at each throttle opening increment - that is 12 pulls for base reading alone and only considering the 10% to 100% throttle range (which is in essence just half the map!)
Even if every other throttle increment and interpolating in between, that is still 6 pulls for baseline alone
And not even touching the idle/off-idle control (below 10%)

Again, I'm not trying to pick holes in your experience and you are clearly happier with the post-tune performance, so that is what matters
Did you get any other plots for throttle openings other than 100%?

@JSHRAM glad to hear you found a tuner in Vegas that’s willing to work with TuneECU.

150 on an SAE chart, not bad at all, though it is a big correction factor, so not ideal weather!

There’s a little room for improvement that will help tame the heat from your headers, if the chart is the tune you rode away with.

Wish he’d given you some part throttle print outs.

Ideally, you want the AFR to track on or close to the red dashed line, usually within a half an AFR point will yield good safe results. In particular from 4000-5200 you can add 10% and pull it down out of the 15:1 AFR range. It may not make any more power, but knowing first hand how hot it gets where you live, it will ensure a good 115f day doesn’t cost you a motor

I see the sheet notes say he added fuel in the 0-15% range, how is the slow speed throttle response now, like below 2000?

Curious what mods you have made to the bike, air cleaner, exhaust, etc.
