KEBAB DRIFTER Posted August 30, 2021 Report Share Posted August 30, 2021 Hi All , New to tuning an i'm awaiting my G4x plug in ecu , with the factory ecu there is a noticeable timing retardation when the vehicle is cold , I believe this is due to the ecu warming the car up quicker it will retard the timing by 15 degrees to enable a faster warm up. Common issue with the factory Nissan RB20 Ecu anything over 50 %throttle or 3500rpm and the car will switch maps and jump back to operating timing and feel like a big surge in power. Im running a straight pipe exhaust and it makes the car sounds horrible (think v6 commodore for the first 10 mins of driving the car) How would i remove or delete this timing retardation on cold starts in the ecu. I drive the car sedately until it reaches operating temperature Thank you KEBAB Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 30, 2021 Report Share Posted August 30, 2021 The cold retard that OEM's use is to get the o2 sensor and catalytic converter up to temp quicker. The G4X doesnt have this feature. Quote Link to comment Share on other sites More sharing options...
