COBB Custom ECU Features

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

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 "93" are for use with 93 and 94 octane fuel or better.
Maps designated with "91" are for use with 91 and 92 octane fuel or better.

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" octane version 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.

If you are unfamiliar with how to datalog using the Accessport or what to look for, you can find a guide on our website here.

If knock or detonation is present even when using the appropriate fuel, try reflashing a map that is intended for a lower octane fuel.

Stage 1 91

Stage 1 93

Map	Peak Gains*
Stage1 91	+26.4% HP / +32.4% TQ
Stage1 93	+31.2% HP / +37.6% TQ

Stage1

Intake Requirements : Stock airbox with stock air filter, drop-in replacement, or COBB Tuning SF Intake System
Exhaust requirements : Stock exhaust or upgraded cat-back exhaust
Boost Target:
- 91 Octane 95 RON Minimum: ~22.5 psi peak boost pressure tapering down to ~13psi as you approach the 6800RPM redline, +/- ~2psi.
- 93 Octane 98 RON Minimum: ~23.5 psi peak boost pressure tapering down to ~14psi as you approach the 6800RPM redline, +/- ~2psi.

Stage 2 91

Stage 2 93

Map	Peak Gains*
Stage2 91	+42% HP / +37.15% TQ
Stage2 93	+42% HP / +43.6% TQ

Stage2

Intake Requirements : COBB Tuning SF Intake System
Exhaust requirements : Stock exhaust or upgraded cat-back exhaust
Intercooler: AMS Performance Front Mount Intercooler GTI
Drivetrain: Upgraded Clutch or DSG Software Recommended
Boost Target:
- 91 Octane 95 RON: ~24 psi peak boost pressure tapering down to ~15 psi as you approach the 6800RPM redline, +/- ~2psi.
- 93 Octane 98 RON: ~25.5 psi peak boost pressure tapering down to ~16 psi as you approach the 6800RPM redline, +/- ~2psi.

Stage 3 91

Stage 3 93

Map	Peak Gains*
Stage3 91	+42% HP / +44.6% TQ
Stage3 93	+46.5% HP / +50.8% TQ

Stage3

Intake Requirements : COBB Tuning SF Intake System
Exhaust requirements : COBB Tuning Turboback
Intercooler: AMS Performance Front Mount Intercooler GTI
Drivetrain: Upgraded Clutch or DSG Software Recommended
Boost Target:
- 91 Octane 95 RON: ~25.5 psi peak boost pressure tapering down to ~16 psi as you approach the 6800RPM redline, +/- ~2psi.
- 93 Octane 98 RON: ~26.5 psi peak boost pressure tapering down to ~17 psi as you approach the 6800RPM redline, +/- ~2psi.

*Peak gains are measured as the difference between the highest points of the two plots.

*Largest gains are measured as the largest gain at any single point between the two plots.

Results may vary. Power as tested on 2019 GTI DSG using these identical calibrations. Generally speaking, the 91 octane calibration has a richer fuel curve and a less aggressive ignition advance map to help compensate for 91 octane fuel and/or less than ideal atmospheric conditions. The map designed for 93 octane is the most aggressive.

High Altitude:

A quick note for those of you that live at higher altitudes: it is common for turbocharged cars at higher altitudes to run less boost pressure due to lower air pressure and air density. Your turbocharger has to work harder to compress a less dense air mass compared to the same turbocharger at sea level. This must be factored in when determining if your turbocharger is running the proper amount of boost pressure and not being pushed beyond its efficiency range.
Example: If you live in Denver at 5280 ft. and are trying to run a peak boost pressure of 15 psi, your turbocharger has to work the equivalent of making ~17.5 psi at sea level.
There are barometric compensations within the factory ECU that lower boost targets as you climb in altitude in an effort to keep the turbocharger in its optimal range. The COBB performance maps utilize these compensations and therefore, it is perfectly normal for the final boost / load value to be lower than what is listed for your map.
