Subaru FA24 E85

Subaru FA24 E85

This option is for doing a remote (email) tune on a completely stock 2022+ Subaru WRX with an FA24 engine and any bolt-on supporting mods as long as the turbo remains stock.  


This tune is specifically for doing an E85 tune which means filling up on E85 only.  This tune can safely account for E60 to E75 blends.  If your ethanol is testing at 80-85%, we do recommend blending in 1-2 gallons of pump gas to bring the ethanol content closer to 70-75% to be more respectful of the fuel system limits on this engine.  Most stations however will be between 60-75% at most times.

With our E85 tune, we do limit the boost a bit in order to ensure that we can run a safe fuel target without running out of fuel capacity from the direct inejctors and pump.  This means our E85 tune will not make some of the higher numbers you may see from other tuners but we do not feel its safe to run these engines that lean.   It can lead to engine issues quickly or over time.  Our E85 tune produces about the same power or slightly more as our E40-50 blend tune but you gain the convienice of not needing to blend fuel each time you fill up.


Estimated power:

E85: 370-390 whp / 390-400 wtrq depending on mods

  • Burble Tune Add-On - $50

    Add some some light crackles, pops or burble (whatever  you like to call them) to your exahust when you lift the throttle above 3000 rpms.

    We do this just like OEM Audi/VW/Ford, etc and it can be setup to your liking but we do not make loud or aggressive nor is it going to "shoot flames".  

    This is done as a completely separate tune that you can flash when you want it and flash back to your regular map when you don't.

    The sounds is based a lot on your catback exhaust.  This video can give you an idea what this effect sounds like:
