Optimum by ZAC Motorsport delivers professional remote tuning and coding services that enhance performance, reliability, and sound. All services are completed from your own garage using the Optimum Tuning Tool with support from our tuning specialists.
Performance Tuning and Logging
Custom ECU calibration tailored to your vehicle, fuel quality, and altitude. Optional data logging and refinement sessions provide maximum power, response, and drivability.
Exhaust Valve Coding

Downpipe Coding (CEL Removal)
Removes Check Engine Light warnings caused by high flow or decat downpipes installed without Stage 2 tuning. Prevents limp mode and restores normal operation.
