I\'m not 100% sure but I dont think you can set the secondary injectors to this size with the commander. You will need the datalogit software.

You will also need to alter the secondary transition (secondary injectors on time. You\'ll need datalogit to do this.

Stock setting is 1.5 ms.

You\'ll know if it needs changing, because the car will stumble on light throttle during the transition to secondary injectors at around the 40% mark. This equates to around 95/100 mph on light throttle cruise.
