What happens here

After replacing the ECU and connecting it to the HP Tuners software via a laptop, perform an initial startup and adjust basic parameters to allow the engine to idle. This includes addressing the significantly oversized 1500cc injectors, which require substantial fuel trim adjustments to prevent the engine from running overly rich or stalling. The goal is to achieve a stable idle before commencing test drives.

Goal: Achieve a stable engine idle with oversized injectors.

Tools and materials

  • 1500cc Injectors — Providing fuel to the engine; requires specific tuning due to high flow rate
  • HP Tuners — Making real-time adjustments to engine parameters
  • Laptop — Running the tuning software
