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.

*** PLEASE NOTE THIS REQUIRES YOU TO SEND YOUR ECU IN & IS A NON-REFUNDABLE SERVICE***
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.

Why can't any ordinary car tuner tune a Polaris slingshot? ( Peter Reyes, 02/27/2017 6:39 pm )
Hey Peter,

When you read out the ECM output, it will just be a long hex file. Someone has to take that hex file and figure out what all of the addresses are doing with engine management before making any modifications. Since the MEFI controller in the Slingshot has a very specific language that is not common to other controllers used in Corvettes, Camaros, mustnags, etc. Other mainstream tuners have not taken the time to map those fields and MEFI Burn is currently the only option available to us for engine tuning.

This is a must upgrade
You will definitely notice the boost in power. The most noticeable improvement
is how smooth gear shifts are. I also bought the 1320 stage 1 header and rear exhaust
Sounds and runs great now !!!!

2017 Flash
I am really pleased with the reflash-The reflash was performed for an increase in fuel economy and modest performance enhancement throughout the power band.If you have a 2017 there are major improvements over the 2015. But the reflash was an eye opener. Smoother shifts, better 4, 5th pull and fuel mileage did whaywhat I asked for. Thank for the superb upgrade Turn around ship day to return Oklahoma - California - 4 days.

A remarkable difference
I waited a while to write this review to give it a proper test drive. I can now say, that I can really sealed the difference after this modification. Everything seems smoother and more powerful, especially in second gear. I would highly recommend that you put this modification on your list if you're serious about improving the performance over the factory settings!
