Dyno sheet is below for my 08 SEUC.  I commented on the lack of A:F chart, and the tuner told me that he can’t do it the way he has it set up.  He can give me all of the A:F charts from all the runs, but not with this one.  Thanks to GH and Hoist! for all the tips on how to get a good tune out of my dealer.  Runs really, really well -- lots of power.  More than I would have believed without doing any further work, and the tuner says that their Dyno is about 5hp less than the one that he worked on before, using his scoot as a baseline.  Not sure the number really means much unless the Dyno is calibrated before and after a run, but that’s another discussion.

I went with the D & D Fat Cats, quiet baffle, SERT, AC and the ghost pipe to make it all look even.  I believe I got the wrong ghost pipe though.  The inside fake baffle doesn't match and it's about 6" inside the pipe rather than out to the end like the real one.  I'll probably take that up with the dealer. 

On my first ride with it I went about 110 miles and could tell it was running pretty rich just going down the highway.  It was fine on acceleration but if I didn't have all the vents adjusted to blow at me I could smell exhaust and it ran HOT.  I don’t have a temp gauge to compare with.  Proof was in the MPG - only got 28, and this was down from 34.  I stopped back in to the dealer and he had adjusted the closed loop settings to 14:1.  I got there 15 minutes before closing and he did it right away, staying after until it was done.  I do like this dealer.  He raised that back up to 14.7:1 and increased the closed loop baseline pressure to 75 from 70 and told me to ride it a while and bring it back if I noticed any more problems.  I haven't noticed any performance loss with this, but the MPG is now 36, which still includes tons of fun acceleration.  Needs to go back for a slight adjustment around 2100 RPM I get a little backfire on deceleration.  Not bad but enough to not be right.

Thanks to this site, I have the right pipes for my riding style and got a good tune even though I don’t have all the answers.  Goes to prove that it’s not what you know but who you know.

What do you guys have against posting your ET sheets.

Is it because these numbers take 6 seconds to develop ?

This was all I got.  If I'd have gotten anything else, I would have posted it too.

BB, looks like you are on this one...I'd like to see one of those ET sheets though, just to see what one looks like.  Of all the dyno tunes that I've had done, I've never seen one...or asked for one for that matter.  I'm having a little motor work done now, so when I get it retuned later this summer I'll ask the tuner for an ET sheet so that I'll know what it is.

I don't understand why nobody has em. They are part of the software for the dyno. No idea why, but most dyno shops never give em to you. I had to go back to the dyno shop that tuned Bubba_T's Mackie rebuild recently and they pulled his up and printed it. So anyway, What it is, is a graph that shows tourque and horsepower curves with the time in seconds shown on the bottom from the rolling start to when the motor is shut down. I've said this before, but in case you've missed it, a motor that hits say 110 TQ and 110 hp at 3 seconds into the run will destroy one that hits say 130 / 130 in 6 seconds. By the time the big number bike hit's his peak, small number bike is already 100 yds in front of him. That's pretty much all she wrote in a drag race or stop light to stop light out on the street.   This is why some people on the site only "race" from a 60mph rolling start. They're running down the highway in 3rd gear at 60 with their revs up and into their power band so then they win. From a standing start they can't. It also explains why a guy with lesser numbers wins a 5th gear roll on. Long story short, is I counsel my friends to look

[SCRM-R]

Yeah, I understand what it is, and I'll ask for one at my next dyno tune.  You've got my curiosity up now...

[courter]

Sounds like it is good information to make comparisons.  The TQ curve was my biggest priority -- and it looks just like I hoped it would.  Best TQ is way down low, and I can really feel it.  Thanks for the additional info!

Here is an example of the ET Sheets you were asking about above.   Top one done in RPM and the bottom one done in Time (sec's).  What you look at is in the top dyno sheet is pick a point of Torque or HP then go to the bottom one and see how long it took you to get there.   Look at 120 torque in the top one then go to the bottom one and look at the timed one to see how long it took to get there.

So that tells us what?  That it took 6.2 seconds to get from 2,400 RPM to 6,500 RPM?  What is the true relevance of this?  That you can go from 40 MPH to 130 MPH in 6.2 seconds?

It seems that the same information also exists in analysis of the HP vs TQ, only that it takes analysis to get the information, not just looking at the peak HP, TQ and ET.

To me, it tells me I'd love to ride that RK!!!

     It's not how much time it takes to get to a particular RPM, it's how much TQ and HP it's producing at that time and RPM. If I'm in my power band running hard and you're still climbing to get to yours, you're looking at my tailights real quick. I'm not gonna kick this around any more. Either you get it or you don't. The guys that get it are the ones that build the bikes that kick a$$ on the street. The ones that don't are the one's riding around with dyno sheets in their saddlebags so they can show their buddies what a bada$$ bike they've got - - - - - on paper.

That's it, I'm done. UNBALANCED can pick up this argument now. He gets it, ask anyone who's raced him, he gets it real good

Please don't get me wrong -- I do understand what you're talking about.  What I'm trying to say is that the time factor on the dyno is not as relavent as the HP and TQ, factored with weight, wind and rolling resistance will give the same answer but in a different way.  It's simple physics.

We're heading for the same destination, but from different directions.  We'll all get there, and you'll probably be first.

Now lets go ridin!

If I'm going faster,  quicker, I'm gonna feed you exhaust fumes. Physics be damned

Guys,

I know their is a place for Dyno Runs in the Ultra Topics, however could not find one for the Electra Glides and I know if this is in the wrong place one of the moderators will put it in its proper place.

Anyway some of the mods since I bought the bike, SBC (Vortec) Headwork, Dave Mackie 595 Cams, Zippers AC and SE Backing Plate )did not have a proper Zippers backing plate for the Zippers 50mm Throttle Body I have, next time) and Supertrapp Supermeg 2:1. Baker OD6 which was on the bike when I bought.

Rest of engine stock.

See the attached Dyno Run.
