An owner of a Nissan Cefiro with 2JZ transplant want a better performance from his stock 2JZ motor.We fitted and tuned his engine with Adaptronic e420d ecu.
Stock engine,0.95 bar boost tapering to 0.85 bar at redline,the sequential twin turbo have been converted to parellel operation and drive by wire throttle body (ETCS-i) have been disabled.
Final result,base run and optimized.We having problems with initial boost response after a few run due to boost control system unstable but manage to find a bit more top end torque and power.
