COBB Custom ECU Features:

These cars offer a variety of added features such as launch control and traction control. For more information check out our guide COBB Custom Features: Volkswagen MQB Platforms

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.

Stage 1

CARB EO: D-660-37

Intake Requirements :
- stock air filter
- Stock airbox with drop-in replacement,
- COBB Redline CF Intake 7A1100 (CARB under D-660-30)
Exhaust Requirements: Stock exhaust or upgraded cat-back exhaust
Boost Target:
- 91 Octane 95 RON Minimum: ~21 psi peak boost pressure tapering down to 16~ psi as you approach the 6800RPM redline, +/- ~1.5psi.
- 93 Octane 98 RON Minimum: ~22 psi peak boost pressure tapering down to ~16psi as you approach the 6800RPM redline, +/- ~1.5psi.

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%)

Stage 1+Flex Fuel

Peak Power is achieved at 30% ethanol content

Intake Requirements :
- stock air filter
- Stock airbox with drop-in replacement,
- COBB Redline CF Intake 7A1100 (CARB under D-660-30)
Exhaust Requirements: Stock exhaust or upgraded cat-back exhaust
Fueling Requirements: COBB Flex Fuel Upgrade Kit 3V2650
Boost Target:
- 91 Octane 95 RON Minimum: ~21 psi peak boost pressure tapering down to 16~ psi as you approach the 6800RPM redline, +/- ~1.5psi.
- 93 Octane 98 RON Minimum: ~22 psi peak boost pressure tapering down to ~16psi as you approach the 6800RPM redline, +/- ~1.5psi.
- Ethanol: As much as an additional 2psi peak boost pressure with the most at 30% ethanol (E30)

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.
