Screamin' Eagle Pro Street Tuner

Part Number 41000008C




The Screamin’ Eagle® Pro Street Performance Tuner is designed to simplify management of engine operating parameters as performance modifications are made. Once installed, the kit allows you to adjust key parameters or simply upload the latest Engine Control Module (ECM) calibrations to match your bike’s state-of-tune. Start with a high-flow air cleaner and Street Performance mufflers and upload the calibration that provides the best performance mix. Add additional Stage Upgrades later, and you simply upload the proper ECM calibration to match the model and hardware. Plus, you have free online access to the latest factory calibrations. Ideal for real-world street performance applications, the Pro Street Tuner provides the adjustability to account for bike-to-bike variation and for changes to cams, heads, intake and exhaust while maintaining closed-loop fuel control for fuel economy in the part-throttle operating range. Unlike other aftermarket tuners, The Screamin' Eagle® Pro Street Tuner actually talks directly to your motorcycle’s ECM and re-programs the motorcycle’s operating system. It isn’t a piggyback system that tries to fool the ECM into adding more fuel or changing the ignition timing. The Pro Street Tuner plugs into the bike’s data port, so no splicing or under-seat hardware is required. And unlike other race tuners or engine controllers, the Screamin’ Eagle® Pro Street Tuner does not impact your Harley-Davidson® factory warranty coverage.

Pro Street Tuner is rated 3.5 out of 5 by 6.
Rated 1 out of 5 by from Windows Compatible Only Despite the photograph in the catalogue (on-line) of the Pro Street Tuner plugged into a Mac laptop, the Pro Street Tuner is only compatible with Windows based systems...not OSX. This despite assurances on the product page that Safari is an appropriate modern browser. Also there are no cables included... so be sure to purchase them if you want to plug it in to your Windows based laptop. As a Mac user (OSX), I guess I'm kind of out of luck...wont be able to use the product unless I buy a computer or load Windows on a Mac

Rated 5 out of 5 by from Required Small part of the total price when I went stage IV plus breather and pipes. I love the tune. Great throttle response off the line and pulls hard through the entire rev range. Could never own a just a stock HD.

Rated 1 out of 5 by from Software won't install. I downloaded the software, tried installing it on 5 DIFFERENT COMPUTERS. It will NOT install on anything I can find from Win XP to Win 8.1. I called HD for help and got no answers. Now I'm stuck with a $330 piece of sh*t and bike that still needs tuning.

Rated 5 out of 5 by from Works on M8 Tri Glide Contrary to the fitment guide, this tuner works on the 2017 M8 equipped Tri Glide. Very nice addition to complete your HD Stage 1 upgrade. Even better, you no longer have to go to the dealer when the mothership updates ECM files and keeps you within the "new" warranty guidelines.

What EXACTLY do I need to make this work?

Hey guys, New Harley owner here (I know, relax gents), I have a 2018 Breakout 107 and I wanted to do a Stage 1 kit to it. AIR, EXHAUST, and TUNER. The AIR, and EXHAUST are easy to install, the tuner i have a question with. If I buy this product, do i need anything else to make it work? Such as extra cables, also I want to install a cruise control button will this affect that at all? Thanks guys, I really like the Harley community, everyone is so nice and thoughtful.
Asked by: TheLegend27
Hey, a 2018 Breakout is a pretty badass first Harley! You will need the cable (about $30) and a Windows computer. I had issues with installing, I had to unpack (decompress) the main download with Win.rar and then run the .exe file and it installed. (you may not have to do this). Just double click the .exe and see if it installs. After that, fire it up and the software will guide you through the steps, or watch the videos on the website. A cruise button won't have any effect on the tuning. What you're actually doing is loading in a new map for the fuel injection to put more fuel in the mix. After you load the new map, ride for a while and check your spark plugs. If they're white, you're too lean and you'll need to increase the fuel a bit more. You do this by opening the VE tables (you can link both cylinders to make it easier) and highlight some or all of the table and click the increase button at the top. Save this as a new file, and then download it into the bike like you did before. You'll still have the first file saved if you want to go back to the previous air/fuel mix. I juiced my Sporty up by 8% and she's running sweet. Have fun!

Stage 1 Maps on Tuner?

2017 Road Glide. I am planning on doing a Stage 1 myself. Does this tuner include a stage 1 map that I can download or do I need to have the dealer do it.?
Asked by: Glidez66
This is a DIY (do it yourself) tuner. Download the software to a PC, watch the training videos and tuner your bike. The software has tunes for all the Stage upgrades. Once you download the tune to your bike you can run some autotune runs to get it dialed in to your bike. Harley also updates the tunes, so if they find something that will improve drive ability or performance they update the tune and make it available for download.

Do I need an internet connection to tune my bike or can I load the map in the tuner then take it to my bike?

Asked by: TLavy
You don't need an internet connection to download maps to the bike. Maps are installed with the software. (beware of viruses...) The software does search for updates each time you launch the app, but if the installed maps are up to date, you should be ok. (I don't imagine that HD updates maps very often). You'll probably be modifying the mapping at some point anyway, so you'll be creating your own. I'm guessing Canada isn't as enviro-fascist as CA (where I live) so you probably have more mapping options than I have.

Will this work if there is already a dealer installed map?

I read an amazon review on the v&h fp3 that it would not overwrite a dealer installed map. He said it had to be set back to the factory map by the dealer before the tuner would work. Is this an kssue with the SE tuner? Im buting a used bike that has a air cleaner and exhaust installed but no idea if its been remapped at all.
Asked by: Bookie60
This isn't the same as the FP3, so I'm not sure how the FP3 works. But after finally getting this installed (download had a virus...) it's been working ok for me. This tuner should let you overwrite whatever is in the bike's memory, but you will need to make a backup of what's in there now. (which is a really good idea BTW).
