The reason for TIVThe anti-jerk function detects oscillations of the power train and damps them out by applying opposing-phase torque interventions. The torque intervention is converted into an ignition angle offset by the torque interface.
In order to damp the power train oscillation efficiently, the torque intervention should counteract engine speed oscillations. Thereby the same effect is achieved as if the attenuation coefficient of the drive shaft is increased.
You can have more power/ Performance but still have exact same peak bhp. Peak bhp is only a reading at 1rpm point to show where the max hp point is.
Performance tuning is about getting as much power from the whole power band. The more average bhp the quicker the car.
I would be happy having a car with 230bhp and 200bhp average over a car with 250bhp and 180bhp average.
2hp peak is nothing, it could be a cooler day, better fuel.
The TIV and TIV+ mapping is allowing us to unlock power from the whole of the torque curve its not aimed to get peak numbers. The TIV mapping also transforms the car on part throttle light load driving. At the moment we are the only company to offer this full TIV reduction mapping for ME9 - MED9 and ME7.5 ecus. It wont be long before everyone catches up
again..lol
Mk5 stock vs stage1 custom with TIV+
1.8T K04 with stage2 and high flow manifold. This graph shows the same map back to back, the smoother map has just the TIV reduction added, so its running the exact same boost, fuel and timing requests. More power and EGTs where 120deg lower.
This both runs have a low filter in the dyno settings so show whats going on during the run. Most rolling roads will have high filters and the lower run with interventions would look smooth bust still lower power. having a low filter allows us to see where the opposing-phase torque interventions happen. But when we allow the timing with no interventions the graph is smooth and a lot stronger
