Warning

We've noticed a few simple issues can cause flashing your car to fail so it's critical to watch out for these problems.

A 10-12 amp battery charger is CRITICAL to keep the voltage stable when flashing, if the voltage goes too low it can cause the flash to fail or brick the module.
If your key's battery gets low and dies or you walk away, the key can become disconnected from the car and cause the ECU to lose flash mode.
Make sure to disable bluetooth on your cellphone as the process in which it connects to the stereo can also cause the flash to fail.

Fuel Requirements:

Each map lists the minimum required octane. A higher octane fuel can be used safely on a map designed for lower octane. DO NOT use maps designed for higher octane with lower octane fuels. Top Tier gasoline should be used where available.

Maps designated with "91 OCT or 95 RON " are for use with 91 and 92 octane/95 RON fuel or better.
Maps designated with "93 OCT or 98 RON" are for use with 93 octane/98 RON fuel or better.
- 94 octane with 0% Ethanol should run the ACN91 Map.

Note

Running 0% Ethanol Fuels

These maps are designed for E10 fuel (fuel with 10% ethanol content). For those who only have access to E0 fuel (fuel with 0% ethanol) it is recommended to use the "91" and "ACN91" octane versions of the maps and datalog the car to ensure your fuel is performing to the necessary level. This is especially important for those using Canadian 94 octane E0 fuel.

- Stock airbox with drop-in replacement,
- COBB SF Intake 7V2150COBB Redline CF Intake 7A1100
Exhaust requirements : Stock exhaust or upgraded cat-back exhaust (2014-2017), upgraded cat-back exhaust (2018-2019)
Boost Target:
- 91 Octane 95 RON: ~22.5 psi peak boost pressure tapering down to ~13 psi as you approach the 6800 RPM redline, +/- ~2 psi
- 93 Octane 98 RON: ~23.5 psi peak boost pressure tapering down to ~14 psi as you approach the 6800 RPM redline, +/- ~2 psi

Stage1+Flex Fuel

E## refers to the ethanol content (E) in % (##). So in the case of E10, it is 10% ethanol (Pump gas is typically between 7 & 15%)

These maps are optimized for use with a stock fuel system. The stock fuel system is maxes out with a blend of E30 (30% ethanol). Ethanol content beyond E30 will trigger a custom COB13 DTC, indicating power output has been reduced.
