Product Details

Please Note: Only available for purchase and shipment in the United States

Throughout their extensive research and development, entrance into the motorsports arena, and knowledge of the European vehicle line, APR has designed the ultimate upgrade for any vehicle. Dyno-proven horsepower increases and complete customization make APR ECU upgrades the absolute best value in performance. Even if your vehicle is stock, APR will extract hidden power with fuel and virtually all engine mapping.

APR has also introduced their revolutionary Enhanced Modular Chipping System, or EMCS. Developed and available exclusively from APR, EMCS allows you to change up to 5 different modes of performance from the driver's seat utilizing your OEM cruise control buttons. This keeps your performance discrete, perfect for those trips to the dealership.

APR achieves all of this performance without putting any of your vehicle's internal components at serious risk. This extra power comes from carefully recalibrated engine control strategies to give you an almost OEM feel with no loss of drivability or reliability often found in inferior systems.

Four different levels on performance let you choose your driving experience. 91, 93, and 100 octane performance levels is perfect for the street or occasional trips to the track. The versatility of choosing which mode to drive your vehicle in allows streetability with performance at the touch of a button. Valet mode lets you turn off the performance of your vehicle and limit speed and RPMs for when the vehicle is out of your hands.

This chip tune/reflash allows you to choose one level of performance or valet. Performance does not need to be purchased progressively, such as one before the other. If you just need 100 octane performance, APR and ECS Tuning are happy to oblige.

All chip tunes can be accomplished via prepaid mail to ECS Tuning. After your purchase, you will be emailed a Next Day Air UPS label to send your ECU to ECS Tuning. Once received, ECS Tuning will perform the chip tune and return the ECU to you within one day. When you receive your flashed ECU, simply reinstall.
