NM Engineering STAGE 1 software is the ultimate for your MINI Cooper equipped with the N14 or N18 turbo engine. Renowned for smooth drivability and exceptional reliability this software has been proven to be the best in exceptional horsepower and torque gains. NM software re-maps boost pressure, ignition timing, air fuel ratios, throttle response and rev limiter (manual trans).

NOTE: Compatible with Stock and JCW Turbo's, US and Euro models. Your ECU must be shipped to NM Engineering in SoCal (fully insured) for programming. Unit is reprogrammed and shipped out in under 24 hours, usually same day.

Stage 1: Stock condition or with simple bolt-on (Intake, exhaust, turbo pipes)

Benefits of the NM flash:

• Factory maps changed not redirects
• RSA encryption and checksum blocks intact
• Original file and P-Chip file saved
• Only one performance file required for different octane, software will adjust
• NM Tune file utilizes factory flash updates which normally comes with 'fixes'
• In-house chip tuning for over 20 years
• Each tune was road-tested for 2 years+ before officially released

See this link for instructions on ECU removal.

Notes:

• Dyno chart reflects wheel power.
• Check local emissions laws for compliance.
• 25-30 HP and 30-35 Ft-lbs gain on stock engine. (15-20 HP and 25-30 Ft-lbs for JCW)
• Intercooler is needed for Stage 2 which will produce additional 20-25% power gain
• 91 Octane or higher fuel required!
• We DO NOT overide check engine light/fault codes produced by low-grade catalytic converters
• ECU needs to be sent to NM Engineering (CA) for the procedure
• Price include Expedited return shipping
• While the ECU is removed from your vehicle, DO NOT TURN ON THE IGNITION
• After you install the upgraded ECU, turn the key ON and WAIT 30 SECONDS BEFORE STARTING ENGINE.

If your ECU gets reflashed by the MINI dealer after the upgrade, NM will reprogram your ECU at no additional cost - you pay shipping.

Limited to US and Canadian MINIs. (Shipping from and to Canada will take longer than continental US addresses).
