Polaris Slingshot Custom Performance Tune by MEFIBurn
Dyno testing has shown that reflashing a stock Slingshot ECM, gains 11 rhp and 18 ft/lbs of torque on just the tune alone, with no other mods. If you pair the ECM tune with other engine mods such as Exhaust, Headers and a Cold Air Intake... this reflash can gain you up to 30 rwhp depending on the mods you've selected. The MEFIBurn ECM reflash improves calibrations to increase overall HP, Torque and drive-ability without breaking the bank. Not only does the ECM reflash gain you power but you can also look forward to smoother mapping and better gas mileage.

Do I have to physically send in my Polaris Slingshot ECM?
  • Yes, you will receive a "Pre-Paid" Shipping label to and from MEFIBurn (Emailed to you after purchase - Please print both labels and include in the box)
Are all ECM tunes the same?
  • No, after hundreds of ECM tunes MEFIBurn has compiled tunes for just about every possible mod configuration. The tune is unique to your mods.
How long does it take to get my ECM back?
  • The actual tune itself only takes 1 to 2 days (on average). Most of the waiting time is travel time for the ECM itself from your location to MEFIBurn and back to you again.

Disclaimer: Be sure to tell your service department that you have a custom performance tune.  Any Polaris ECU update MAY overwrite your performance tune. Please note a dealer may be able to deny a warranty claim if you have a custom tune for your Polaris Slingshot.

Ecm reflash
Ecm reflash has been done, after the reflash i drove it about 200 miles, after that I started having cam codes, replaced the cam sensors and so far so good with no codes. I wish it would come with paperwork of what parameters that they have changed or added.

Wow... just wow.
So I have my 2017 Slingshot SLR almost a year now.. only have a Cold Air Intake.. no exhaust yet. I was a bit skeptical on this tune as I wasn't sure how much of a difference it will make as I don't have that many mods yet. But based off even on a stock Slingshot, you're getting +11rhp/+18lbs of torque and more if you have mods. It doesn't seem like a lot but it is considering the curb weight is not even 1800 lbs. You'll notice the difference as soon as you've gone through the first 3 gears. The engine is now alive and pushing through a lot harder and smoother. The only downside is you need to remove your ECU which is super easy (un-clip 3 connectors and remove 2 bolts) 5 minutes max. Shipping is fast with FedEx and turn around time was super fast. Highly recommend this tune. A+++++++++++

Ecm refi
Low end response is great. The sound is even a little deeper. I would recommend this tune-up to anyone who wants to upgrade performance.

A must mod
I am from Canada I shipped it to bobs and it was returned in about 4 days. I have cold air intake , headers and exhaust. The increase in power was more than I expected. This makes the slingshot ride like it looks.

ECM Flash/Tune
Very impressive tune and shipping speed!! I even called in because it seemed to get back to me too quickly so I thought something was wrong. However once I did the reinstall and drove it I knew...Money well spent!! Responsiveness, idle, low and high speeds have it feeling like a totally different vehicle now!!
