2002-2003 AccessPORT Map
Info File Last Updated: 9/2/04
Map Name: Stage2 93 oct
Description: Stage 2 using 93 octane fuel. Requires stock turbo, stock intake and turboback exhaust. 280HP / 285 ft-lbs.
File Date: 9/2/04
Latest Rev: 1.20
1.20 - Added additional CEL defeats listed below. Revised fuel mapping under full load, primarily between 3000-5500 RPMs to accomidate a wider range of vehicles and smooth power delivery. Revised wastegate duty cycle maps to smooth boost response. Revised boost target maps for smoother response and better partial throttle driveability. Raised Rev Limiter to 7250 RPM.
1.19 - Original mapping. Based on the AccessECU Stage2 reflash version 1.19.
Base Map vs Real Time Map Differences -
The base mapping contains some additional logic for improved performance and is HIGHLY recommended to be used if you plan on operating at a Stage2 level.
For use with a stock turbo, stock injectors, stock intake and a TURBOBACK exhaust system. Additional modifications such as uppipe and underdrive pulley are still within the acceptable parameters of this mapping. MUST USE FACTORY INTAKE. NO AFTERMARKET INTAKES ARE CERTIFIED COMPATIBLE WITH THIS MAPPING.
Best if used with 93 and 94 octane. For 92 octane please use the 91 octane mapping.
Target boost pressure is 15.8psi +/- 0.5psi depending on vehicle and conditions. If after 1-2 weeks worth of driving you are still unable to reach target boost pressures, you may try using the HWG version of this map.
Target A/F Ratios are mid 12's under load before the onset of boost. Under full load by 3500 RPM the A/F Ratio will drop to mid 11:1 and gradually run richer as RPM's increase ending at mid to high 10:1 A/F at redline.
The "Speed Limiter", which in reality just turns off boost control above 130mph, is removed.
The Rev limiter at 7250 RPM.
