Stage1

  • Intake Requirements: COBB Panel Filter 7B1110 Covered under CARB EO D-660-7

  • Intercooler Requirements: Factory Front Mount Intercooler

  • Exhaust Requirements: Stock exhaust or upgraded cat-back exhaust

  • Boost Targets

    • 91 OCT or 95 RON 10psi peak tapering down to 9psi by redline +/- 1.5psi

    • 93 OCT or 98 RON 12.5psi peak tapering down to 11.5psi by redline +/- 1.5psi


C.A.R.B Note

The above Stage1 calibration is legal for use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it and the parts have a California Air Resources Board (CARB) Executive Order (EO) number: 

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

Revision Notes: 

v202 –  Maps renamed to follow standards for Octane rating
Aggressive renamed to 93 octane/98 RON
Sport renamed to 91 octane/93 RON

v201 – Corrected Fault Logic In Stage2 Maps
Only affects N55 vehicles with 98G1B or 98H1B ROM ID running Stage2 Maps.

v200 – Updated Calibration Logic
Implemented new D.M.E. logic to allow more accurate calculation of load target/requests.
Stage2+: Logic and tuning parameters have been adjusted in order to capitalize on Stage2+ hardware. See hardware requirements for a list of needed upgrades.

v100 – Original Release Calibration
Stage 1: Adjusted boost levels, fuel, ignition, and base programming logic to improve performance and reduce ECU interference over vehicle driver’s input. Torque and load limiters adjusted or altered to allow for significantly increased power over stock levels. Fuel mixtures have been appropriately tuned for increased power levels to provide safety and performance.

Stage 1+ COBB FMIC: Logic and tuning parameters have been adjusted in order to capitalize on Stage1+hardware. “Stage1+ COBB FMIC” mapping requires a COBB front mount intercooler.

Stage2: Mapping Intended for vehicles with COBB downpipes or full TBE. Adjusted boost levels, fuel, ignition timing and base programming logic to improve performance and reduce ECU interference over vehicle driver’s input. Torque and load limiters adjusted or altered to allow for significantly increased power over stock levels. Fuel mixtures have been appropriately tuned for increased power levels to provide safety and performance.
