Engine tune and octane
I always use European 95 octane (which would be same as US 90.7) because over here that is the lowest available.
Would that be considered premium, as mentioned in the RPM Motorsports tune description ? Is a bit lower, but could I get away with it ?
Perhaps I can install the tune without the need to get the more expensive European 98 octane (which would be same as US 93.5)
Solstice / SKY 2.4L LE5 Stage 1 Tune
Cooling Fans set to 205F
Fan speed increase for more rapid cooling.
Speed Limiter Removed
Mass Air Flow sensor calibrated for most cold air intakes on the market.
Power Enrichment delay removed to allow for more immediate Full-Throttle response
Air Fuel Ratio adjusted for better performance.
Timing Calibrated for Premium Grade Fuel. (91+ octane).
Low end torque and fuel economy improved by adjusted timing
Spike at ~4,000rpms less severe due to a more linear power curve
Top end timing advanced 2-3 degrees for better peak horsepower
RPM Limiter increased in manuals to allow for more aggressive full throttle shifts
Torque Management (granny controls) removed to prevent computers from reducing torque output below 3,000 RPMs
Typical gains: 8-12HP and 12-18lbs of TQ
*NEW* Automatic Transmission equipped cars now have Full Throttle Shift points raised to 6,750 RPM.
*NEW* Automatic Transmission shift time reduced by 0.25 seconds per gear change.
