APR Stage 3 TTE700 ECU Software EA855 DAZA

The APR Stage 3 ECU Upgrade for the Audi RS3 8V.2 DAZA and TTRS 8S DAZA is the next step towards making more power! This stage is available for multiple setups, and are all designed around using a drop-in turbocharger upgrade. Stage 3 has specific software for the TTE700 and GTX3582 drop-in turbo upgrades. Both require a APR TCU Upgrade, race DP exhaust system, midpipes, Bosch 980cc port injectors (0280158040), turbocharger inlet system, intercooler, and NGK heat range 9 (NGK-R7437-9) spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km.

The TTE700 requires the included wastegate actuator. The GTX3582 requires the included turbosmart wastegate actuator and MAC 3-port solenoid. A proper 500 LPH+ @ 6 bar LPPF is required to run E85, but the stock LPFP is ok for all other fuels. The TTE700 produces 576-713 HP with 523-536 FT-LBS of torque. the GTX3582 produces 581-740 HP with 511-555 FT-LBS of torque. RHD vehicles without the turbo inlet will experience reduced output. In all cases, torque is kept flat to aid in component longevity.

This stage has optional high and low grip modes designed to reduce wheel spin and aid in 60 FT and 0-60 times depending on surface prep. Additionally this stage is available with optional exhaust crackle modes. The more aggressive modes increase the length, duration, intensity, and operating modes of the exhaust crackle. Aggressive modes are only recommended with testpipes. APR recommends NGK heat range 9 (NGK-R7437-9) spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km.

Currently available for 99RON and E85 fuel grades/
