{"product_id":"stage-1-ecu-performance-tune","title":"Stage 1 ECU Performance Tune","description":"The Unitronic Stage 1 ECU Performance Engine Tune is a sophisticated engine control unit (ECU) performance software upgrade engineered for the VW\/Audi GTI, Golf R, and S3 models equipped with the MQB EVO 2.0TSI engine. This tune is precisely calibrated for 91 octane\/95 RON fuel, delivering substantial power increases over stock while preserving OEM-like driving characteristics and exceptional reliability.\n\nAdvertised power figures require the use of Unitronic Stage 1 TCU Performance Software, a Unitronic Intake with Air Duct, and a Unitronic Intercooler. For the MK8 GTI, expect gains of +95 HP and +79 LB-FT, reaching a total of 336 HP \/ 352 LB-FT. The MK8 R and 8Y S3 see gains of +71 HP \/ +57 LB-FT (MK8 R) and +80 HP \/ +72 LB-FT (8Y S3), resulting in 386 HP \/ 367 LB-FT for both.\n\nKey features of this tune include optimized responsiveness, smoothness, drivability, and comfort. It offers precisely calibrated ignition timing for higher octane fuel, optimized maximum output, and power delivery throughout the power band. The speed governor is removed, and improved fuel efficiency is also noted. Factory safety limiters are retained.\n\nThe UniCONNECT+ system also provides capabilities for data logging and easy restoration to the factory stock calibration. Unitronic recommends specific battery chargers to ensure uninterrupted flashing.","brand":"UNITRONIC","offers":[{"title":"Default Title","offer_id":52689528881464,"sku":"UNI-EC85-MK8","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687751122.webp?v=1784907335","url":"https:\/\/store.motormia.co\/products\/stage-1-ecu-performance-tune","provider":"MOTORMIA","version":"1.0","type":"link"}
