Well I finally got a chance to get my bike to the dyno. It didn't work out like I had planned, but it seems I did go to a rather competent tuner. It was just a bit out of my way.

What I'm working with.....

-'09 FLHT
-Factory 96" motor (no internal mods)
-PC-5
-V&H Dresser Duals
-CFR mufflers
-PM AC w/ K&N

I called my initial choice for my tune and got the run around. Didn't know if they could get it done, couldn't get ahold of the actual tuner to ask him, blah, blah, blah! Well, they just lost my business. Too bad because they were about five minutes from me. As the barber said, "NEXT!" Called another recommended tuner, couldn't fit me in. Booked till next Wednesday and rightfully so as they came highly recommended. Wasn't too upset about that one as it's my fault because I wanted it done ASAP.


Ended up taking it to Mickey Cohen of Mickey Cohen Motorsports located in Placentia, Ca. (714) 276-0478. Had many, many race cars and bikes there.

Dropped it off at about 11:30AM. He told me to come back in an hour, hour and a half. He actually said go get some breakfast or lunch and come back. Cool guy for sure. After eating lunch, called him. It was about 12:45PM. Said it was ready, come get it.

When I got there I asked him what it was like before he tuned it. Told me the AFR's were all over the place and something about the torque. Can't remember off hand. I'm going to call him to see if he has anything on his computer from before the tune so I could compare.

Anyways, here's the sheet.




Let me know what you think!
 
What did he charge you for the tune? Local guy here said 3-4 hours to tune. All the shops in the area use him. Hour 15 mins. is pretty quick from what I've been led to expect.
 
Can someone discuss the curves? I don't know a whole lot about these sheets, but how do they look? What are they supposed to look like, etc.?
 
An hour and 15 minutes is pretty short. Dave tuned the Night Train's stage 1 for almost 8 hours to get it right.

It'd be nice to know if those graphs are SAE, and what smoothing was used. I'd also love to see what the canned map looked like.

But based on what you've got there, it looks pretty decent. How does it feel? That's really all that matters.
 
I had zero issues when the bike went in. No decel popping, no backfiring, nothing. Just wanted to make sure the bike was running as efficient as possible. Maybe that's why it didn't take that long. Maybe it was running at it's best when it went in. Who really knows? I guess the only way to really tell was to have had a pull done before I went in which I didn't do. I do know it is running better.

I was under the same impression that it would take a while to get it right. At least that's what a lot of people say. But if the tune isn't that far off, can it really take 3-4 hours? Does anyone really know how long their tune took unless they sat there and watched the whole process? I could have easily kept my tune and been happy.

On a side note, I had talked to a different tuner before I went to the tuner today and he told me it shouldn't take that long to get the tune right if I was having no issues. Just a few changes here and there and it should be done.



What did your tune look like before you took it in? Did you have any issues? I'm not knocking your tuner, but how can it take 8 hours? What were they doing? Changing components? All the places I called told me tunes are usually $300.00 (3-4 hours.) I'm sure there is a time limit on that price and $300.00 wouldn't cover 8 hours. I mean a tune can take an hour or up to 8 hours, but do you really know unless you sit there and watch.

I can feel that the bike runs better. Especially when just cruising on the freeway in a certain gear and then gassing it while in the same gear. It used to lag some. Now it does not. I haven't really got on it yet, but so far it seems better.
 
Don't worry about the short time on the dyno. Your setup is is basic a/c and pipes. If he's a good tuner he simply loaded a map he's been tweaking for years that matched your setup. A few tweaks for your bike's specific needs and it's good to go.

The most important thing, as others have mentioned is, are you happy with the way the bike runs? Are you happy with the fuel mileage? If you are than your tune is perfect.
