Yea I here ya.

Actually I've used the dyno at the harley shop near me many times. They are real cool about it. I can just use the thing. They always like my bikes because they get to see what is being made.
They liked my air/oil motors.(suzukis)
And they shit when the CBR made 147 they couldnt believe it.
They said a 150hp HD engine would be more than this bike cost when I bought it new.

The day the 12r rolled in there they started to laugh and say what now. Before he did the first run he told me "this fuckin thing better not kill me..."
These guys like the high tech shit. They fully admit HD makes junk. But they make alot of money making,building and fixing them fuckers. Guys there is HUGE money in that crap.

...because I haven't made the trip up to swft's shop yet (or someone like him)....actually, I just don't know who to trust around here and I'd rather have a shop who is UP TO DATE on what's going on with the 12R and how to get the most out of it...so there it is....

I couldn't wait on a Yosh box.

Or should I say, still be waiting on a Yosh box. Hell, I couldn't wait for the PCIIIR, either. Still, the Yosh box is nice but rather pricey when all the options are added in and then how long will it be for non-Yosh pipe owners to get maps? Other questions, like can the Yosh box interface with a dyno (don't know) or computer (probably)? I've had my 12R for 20 months now and there's no way I could have waited this long for such a device. No matter how many cool bells and whistles it has.

As for the nearest dyno that's capable of tuning a PCIII is about 340 miles from here (Little Rock to Dallas). There's only one dyno locally and it's a old DJ150. With just a Muzzy pipe and MH filters, I ran a 167.4, 172.8 and a 174.6. We all know that a DJ150 can be a little "happy" with the numbers and of course, can't interface with a PCIII.

Last May at the Gap, my 12R did a 176.1 & 97.7 on a portable DJ250. Dave in Daytona has a similar set-up as mine and did a 181 & 101 on the same portable dyno at Gap II last September. My A/F ratio was a tad rich through the midrange, but close to right on at the high end. I'm currently running Dave's map and am pleased with it.

This is the tough part about it, I'd have to trailer my bike close to 700 miles, pay $300, spend 3 hours at their shop and I'll end up with a map that will have some minor tweaks to it... at best. Jim Sabin at Sabine Performace has been very nice and informative in our exchange of e-mails. He's even offered me some form of discount because of the distance I'd have to travel.

Still, 14 to 17 hours of trailering/dyno time and $300 is a tad too much for me, right now. Especially with the possibility of getting a map that has just a few minor changes from what I already have. For an additional $90 or so, I can have Race Tech revalve my forks. That would be a higher priority.

I guess I'm lucky

Jeff's dyno is about 1/2 mile from my house and I have a custom map.He's getting the updated Dynojet stuff in jan with the load cell and it makes the correct map for you.Jeff is really good at doing the maps manually.He's done lots of maps.He even does boat anchors.

I wouldn't say that I'm disappointed - I just wonder if it was really worth the expense.

The bike ran good when I took it in to have the map made and the bike ran good when they finished making the map! Biggest difference I could actually tell (by riding it - not looking at the paperwork they gave me!) was that the engine was definitely smoother. Smoother vibration-wise (not that it was particularly buzzy when stock) and smoother power delivery. Now then... to me this was good and bad at the same time! Good because everything was "smoother" and the air/fuel ratio was pretty much a flat line from 4,000 rpm up to the rev-limiter. Bad because that wonderful "hit" at around 7,000-7,500 rpm was gone - the bike actually felt slower --- too refined?? It just seemed to take out some of that kick-in-the-pants top end rush that I love.

Also, I've seen others say that they've gotten an increase in peak horsepower with custom mapping. I'm pretty damn sure I didn't gain any peak h.p.. I had the Dynojet fuel map for the Yosh RS-3 Duplex pipe and Hank's ignition timing map already loaded into the PCIIIr when I took it in for the custom map. When they were done creating the new fuel map there were several differences in low, mid and upper mid-range rpms, but absolutely no change to the values up near the top. In other words, whatever peak h.p. I went in with is what I came out with!!

So.... I think the mapping I had done was beneficial from a driveability standpoint, but not worth a penny in the quest for upper rpm power. I just wonder if it was worth the $$$ for what I got.

I'll experiment with tweaking on my custom map next spring. If I don't like the changes I make I can always put it back the way it was. Wish I had the bucks to have my own DJ250!!

Carry on.......

Fish!! What the fuck?? You know I run a DJ250! Oh, I see, it's easy for you to flounce your candy ass down in a cage for a Mariner's game, or the motorcycle show, but you can't handle sitting those pearly cheeks on your 12 long enough to get it down to the shop??

How does one ( ME ) go about finding someone/
someplace good?????????

My 12 is 100% stock ( so far ), I'd like a baseline,
But I WILL NOT deal with alot of typical "punks"
( Exapmle: Some of the Dealerships here...)
telling me what I need/dont need to get.....
I have no time OR tolerance for that shit.
( Some weasel fresh out of MMI is not what I had in mind.)

Any suggestions at all,on where to start, will help

I worked on my map myself for quite a while. When I put it on the Dyno the operator said it was as good as it gets and wouldn't recommend having a custom one done because it wouldn't be any better than what I had done.

9R, No Dynos in Daytona ? - I know of 5, there may be more, Crane, AMI, PCS, Carl's, DB HD.

Sure fish but a full tune at our facility is pretty pricey....

It is probably going to cost you AT LEAST 1 gooooood hangover. And a ride to the Beartooth wilderness while your here.

*grin* Fish will never do it. I've let several customers go after an initial run and analysis. Sometimes the map is so close to optimal that the expense is just not worth it.

I'd just like to know, Who misses fiddleing with jet size, needle position, and float-bowl levels? Or is the general opinion that FI systems are definatly better? Just wondering.

OK Educated Me

My limited experience with dyno tuning and PC3Rs has been the one time I watched a friend dyno his gsxr1000. He changed his ignition and fuel settings via a laptop that was plugged into the PC3R. The only other connection between the bike and the dyno was the connection to read the rpm. My question is

Are you actually hooking the PC3R to the dyno's computer and making changes to the PC3R's settings with the dyno's computer or are you making changes with an external computer that has the PC3R software on it and doing multiple pulls on the dyno to see what the results are and making adjustments to improve the results?? That's how the guys I watched were doing it, i.e. make run, modify settings, make a run compare to previous runs, make adjustments. Incidentally, there was nothing measuring the composition of the exhaust. I think I've seen what looks like a gas analyzer hanging from the pipes in some of the photos. How important is that measurement in tuning the bike for peak performance??

Also my friend with the 00 12R has a PC3R and an Akaprovic pipe but he is using DynoJet map for the Akaprovic. He has not made any other adjustments to the map and seems to be happy with it.

Are you serious?
Do you like? the smell of gas???
I don't EVER want to pull another carb to tune it but...that WON'T happen for several more years...I'm affraid...

PLUG IT IN...plug it in...
I'm NOT talking about air fresheners either...

Carbs

I still have bikes with carbs, and I am so sick of carbs.
When that cbr1100 was gone I swore off carbs forever.
The gs 1100 wont be apart anytime soon.
My wifes bike needs a carb dial in.(CB-1)
But she doesnt complain and I dont have time.

I still like to mess with the V-8's.
Was just working tonight with a set of dominators on a BIG big block chevy on the dyno. Nothin like getting up close and personal with a HOT engine that just made 977 hp 1 minute ago.

Carbs suck.

poll addition

You need to add the following selection to this poll:

" I dyno'd with the PC3 and a custom map and lost 5hp vs without it".

I'd vote for that one.
