This is a Single Fuel, Speed Density ETune or "Quick Order" for FA20 Cobb ETunes.


With all the issues with Intakes, MAFs, and BOVs on the highly sensitive FA20s MAF system; going Speed Density is a very popular option lately. So much so I have made a quick order for it. The FA20 WRX requires ZERO hard parts to have a fully functioning SD tune. It uses the OE Port/Manifold IAT sensor for SD Compensations.

Got a Cobb Big SF or BOV and tired of crazy AF learning and stalling? Buy this!


"Single Fuel" meaning Tuning on one octane either being 93, 91, E30, E60, E85 etc.
