The Pro Street Tuner will let you add a auto tune session or manually adjust the VE tables in the Working Table, not the original table. I don't see any reason why MyTune adjustments couldn't be added to your Map, but I've only actually used MyTune with my SE Pro Super Tuner on my 2013 Ultra... Just now getting back to a Street Tuner on my '17 due to the Frickin Warranty BS...

 

ooops

 

Hi all -

Can someone recommend a map for me to start out with? I’ve got a SE super tuner which has been sitting in the box since the dealer did the stage 1 on my bike back in 2012. I’m installing cams now, so id like to get a good starting map loaded on the bike before I can get it over to the dyno tuner. Thanks guess all I have to buy is the cable?

Here’s what I’ve got:
2012 FLHX
SE air cleaner
Rush ceramic headers
Rinehart true duals
Andrews 57h cams
No headwork or anything else

Thanks.

 

Harley finally got me an answer, the new Softail download maps merely have a typo that says they are Twin Cooled. This is supposed to be rectified in the next update. I put on the SE Slipons, Intake and dropped in the Stage 1 tune. Seat of the pants feel is significant and the Street Cannons sound very good. My bike isn't broken in yet, so I'm waiting, for miles to Smart Tune.

 

Just saw the update for the HD Tuner A/O 11/16/17.
looks like they corrected the softails as being twin cooled and now there is a REV A for the 2018 softails and REV C for the 17 touring models.
Seems as they update almost as often as my Iphone.
which by the way I really wish you could run the software from your phone like an APP.

 

Hi Folks,

This may have been asked before but I am having on heck of a time searching so here it goes...

I have a 2018 Road King Special approximately 500 miles, stock, however, I want to change/swap the air cleaner to either the SE ventilator or the heavy breather, add the SEPro/Street Tuner, but keep the stock pipes...my forth Harley and really am not want to change the factory stock muffler/pipes as I like the way the exhaust sounds.

Question to the group is, other than not allowing a free flowing exhaust:

1. Are there any short or long term issue?

2. Will the change marginally improve performance?

3. Will my current stock MPG @49mpg, decrease or increase?

4. Will I experience increase engine heat or higher temperature?

5. Will I get approximately 10% HP & Torque increase using my stock factory mufflers?

Will this just be a complete waste of money without changing the muffler to Vance & Hines HI Output which I was considering but I've heard, this pipe it could negatively impact low end torque due to its 4.5' diameter size.

Thanks for listening in advance...

 

In order:

1. No.
2. Yes.
3. Should be no significant change.
4. Should be no significant change.

Since you are only using genuine Harley-Davidson parts, and you are tuning the bike using a Harley-Davidson Screamin' Eagle Pro Street Tuner, you're absolutely doing everything by the book.

Have fun!

Edit: Forgot to answer the last question! No, it won't be a complete waste of money.

However, adding a Vance & Hines exhaust could be problematic, particularly if it does not have a catalytic converter. At that point, trying to retune the bike using the Pro Street Tuner will no longer work, because it's not capable of handling the changes in air/fuel flow caused by the combination of both the air cleaner and exhaust. If you use another tuner, your powertrain warranty is void, as is the powertrain portion of your ESP, if you have one.

 

Thanks for the response...with regard to the V&H Hi Output, I have no plans to change the stock headers and correctly me if I am wrong, have the CATs been moved to the mufflers on the M8 models?

I was under the impression that it was still on the stock headers...

I only have the standard two year factory warranty and yes, I have been made aware of third party tuners, other than SE, could void power train warranty...

One other question is, will I get approximately 10% HP & Torque increase using my stock factory mufflers?

 

Changing air cleaner assembly, changing mufflers and adding a tuner may or may not make a 10% change in the top numbers of torque and horsepower, but might increase the area under the curve, making more usable power throughout the rpm range. As long as you keep the stock headpipes, choice of muffler is up to you.

 

No plan on changing the stock headers/head pipes and the factory stock mufflers...would this setup still provide some torque or HP gain?
